Flip Through . Plant asters (genus aster) in your butterfly garden, and you'll attract any number of the 100-plus Lepidopteran larvae looking for this host.As an added benefit, asters bloom late in the season, giving migrating butterflies a much-needed energy source when other flowers are past their prime. It was Eisner who noticed the alkaloids that allow the bella moths to flourish are poisonous to some other bugs, including spiders. The pods resemble pea pods and rattle when the plant stem is moved. Adults: The adult ornate bella moth is a rather small moth (wingspan 3.0 to 4.5 cm). Today, the plant would control many Florida habitats if it weren’t for the tiny pinkish-red ornate bella moth keeping it at bay. You are what you eat: native versus exotic Crotalaria species (Fabaceae) as host plants of the Ornate Bella Moth, Utetheisa ornatrix (Lepidoptera: Erebidae: Arctiinae) Journal of Natural History: Vol. Moths of Western North America. (In Latin). The pupae are encased in a brown and black sac covered in a light coat of silk. which are both native to Africa and Crotalaria spectabilis Roth which is native to Asia. Host plants for the moth’s caterpillars are both native (four species) and non-native (10 species) Crotalaria, known as rabbit bells, as well as rattlebox for the rattling sound of ripened seed pods. Cannibalistic caterpillars (. A common native host plant for these moths is the Crotalaria avonensis, a beautiful plant with yellow flowers. Adults are concentrated in patches of Crotalaria. According to Fairchild, this particular plant was introduced from India around 1914. Today, some Crotalaria plants are still used as cover crops in the United States (mostly in the South), and around the world. He found C. spectabilis growing in Micanopy Hammock in 2013 had its seeds depleted by the bella moths from July through October. Also known as Moth Plant, Kapok Vine, Araujia Sericifera. Adults are approximately 1.5 inches in wingspan. Fun for children of all ages. The children were able to see the contrasting colorful spoonbill pink hindwings and how they are hidden at repose by the camouflage patterned forewings. Why do larvae of, El-Sayed AM 2014. (Hymenoptera: Scelionidae) (Bezzerides et al. The woolybears, tiger moth larvae. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. Males convert some of their Crotalaria alkaloids to a related compound hydroxydanaidal (HD), and upon approaching a female, expose two eversible brushes (coremata) from the tip of the abdomen that contain HD saturated scales (Conner et al. Freshly emerged adult. are treated as generic only. A year later, he noticed the seasonal plant had dwindled more than 90 percent. Sourakov said species of rattlebox have also been occasionally documented to grow among crops, ultimately contaminating cereal consumed by humans, and herbs used in tea. “In this day and age, some of these rattlebox plants probably wouldn’t have been introduced because people are more aware of the negative impacts of introducing exotic species and how they can became a nuisance,” he said. Leaves are arrowhead-like in shape (3-12 x 2-6 cm) and alternate on the stems. https://butterfly-conservation.org/moths/elephant-hawk-moth The sweet smell of success. United States Department of Agriculture. This allows it to be witnessed more frequently than other moths, which are mostly modestly colored and nocturnal. (2000) who reported an overall parasitism rate of 20% and suggested that pupal parasitism may be one of the chief causes of mortality in Utetheisa ornatrix: In laboratory studies (Storey et al. Unlike most moths, which are nocturnal, the ornate bella moth is diurnal and flies readily when disturbed. Though such occurrences are rare, the health concerns prompted testing of some products for Pyrrolizidine alkaloids – the harmful components of Crotalaria. North American Moth Photographers Group (, Pease R. 1968. Adult moths live for about 4 days and do not feed. Postcopulatory sexual selection in an arctiid moth (, Linnei C. 1758. Pupae: The pupae are black with irregular orange-brown bands and are covered with a loose layer of silk (Figure 4). Getty Images/Kevin Dutton. Semiochemicals of. Sourakov, with the help of UF undergraduate students, is now continuing to explore the ongoing coevolution of plants and moths. Hummingbirds and butterflies are attracted to the nectar produced by the flowers while birds and small mammals eat the fruit. Heritability of body mass, a sexually selected trait in an arctiid moth (, Iyengar VK, Rossini C, Eisner T. 2001. 286-291. Pyrrolizidine alkaloid deters ant predators of, Hare JF, Eisner T. 1995. Showy rattlebox, Crotalaria spectabilis Roth., a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). Need two plants to cross-pollinate. The bella moth is one of the few insects that have evolved to use the Rattlebox as host due to the plants extreme toxicity (the plant is laced with pyrrolizidine alkaloids). “They can’t tell the difference between the native and the invasive species. Adults are approximately 1.5 inches in ... leaves of the host plant, and at later stages, they feed on the seeds, which contain more alkaloids. System Naturae. 1999), the jumping spider Phidippus audax (Hentz) (Eisner & Eisner 1991), and the orb weaving spiders .Trichonephila clavipes (Linnaeus) (Eisner & Eisner 1991, González et al. Figure 7. 930348.00 – 8105 – Utetheisa ornatrix – Ornate Bella Moth – (Linnaeus, 1758) Photographs are the copyrighted property of each photographer listed. But by late November each year, the plant had nearly disappeared. Butterlies get most of the attention with their bright colors and sun-loving ways, but a variety of beautiful moths can be supported as well. Bella Moth - Utetheisa ornatrix Bella or Rattlebox Moths are one of the most colorful moths found in Florida. Guide to the Vascular Plants of Florida. Among them is Crotalaria spectabilis, showy rattlebox, which particularly stands out with its 6- to 8 feet-tall plants and beautiful yellow flowers. This is a fascinating discussion about the ecological consequences of invasive plant introductions. Clusters of 2-4 bell-shaped creamy coloured flowers (20-25 mm diameter), occasionally with pink streaks, appear from December to May, followed by distinctive thick, leathery, pear-shaped choko-li… Part IV. The caterpillars of Utetheisa ornatrix, the ornate bella moth, feed on host plants in the genus Crotalaria (Fabales: Fabaceae), which, in Florida, encompasses 4 native and 10 introduced species. Just like with milkweed butterflies like the monarch or queen, the color of the rattlebox moth is intended as a warning to potential predators that eating it will make you sick. Wunderlin RP, Hansen BF. While not all moth are pollinators, they do have unique realtionships with native plants, and provide an important food source for birds as well. Sourakov has taken research of Eisner and his colleagues forward, out of the lab and into the real world. Adult and larva of the ornate bella moth, Utetheisa ornatrix (Linnaeus). This leads to another common name for the Bella moth: rattlebox moth. Fanning the female with the coremata stimulates her to raise her wings exposing her abdomen. In addition to sperm, males also transfer nutrients and HD to the female during mating via the spermatophore. His pioneering lab experiments involving bella moths revealed how insects use chemicals to attract mates as well as prey, and elude predators. “The moth has always fed on native species of Crotalaria,” said Sourakov, showing a drawer with hundreds of bella moth specimens that he reared in the lab. Biparental defensive endowment of eggs with acquired plant alkaloid in the moth, Egan AL, Hook KA, Reeve HK, Iyengar VK. Figure 6. The ornate bella moth is found from Connecticut westward to southeastern Nebraska, and southward to New Mexico, southeastern Arizona and Florida (Covell 2005, Powell & Opler 2009, North American Moth Photographers Group Undated). Female choice increases offspring fitness in an arctiid moth (, Iyengar VK, Eisner T. 1999b. A common native host plant for these moths is the Crotalaria avonensis, a beautiful plant with yellow flowers. Gmel.). 1972. Proceedings of the National Academy of Sciences USA 97: 1634-1639. Unpalatability of the pyrrolizidine alkaloid containing moth. 538-542. Sourakov stumbled upon one of Florida’s 10 exotic species of rattlebox (there are four native species) in 2011 growing near the edge of a wooded area in northwest Gainesville. A Field Guide to Moths of Eastern North America. Many other species of Crotalaria were introduced into the southeastern U.S. 55-65 years ago for soil improvement and forage. 2011. McGuire Center for Lepidoptera & Biodiversity. Only four species of Crotalaria are native to the southeastern U.S. of which two occur in Florid… Learn more about the McGuire Center for Lepidoptera & Biodiversity at the Florida Museum. 2006). This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 1960. The ornate bella moth, Utetheisa ornatrix (Linnaeus), is one of our most beautiful moths (Figure 1). Therefore, it is more commonly seen than nocturnal species of moths by the public. This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). It is the same root word as used in the genus name for rattle snakes, Crotalus. Today in Florida, these exotic species often grow on abandoned farmland that has transformed into forest. 2010, Tietz 1972), species in the genus Crotalaria (e.g., Figures 7 to 10) are without a doubt the major if not the only true hosts. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. (For chemical structures of Utetheisa ornatrix pheromones, see El-Sayed (2014). Parentally provided alkaloid does not protect eggs of. It is not clear if people who introduced rattlebox plants were aware they are poisonous to livestock and can become nuisance invasive exotics, sometimes completely overrunning the ecosystem. Vol. (2016) and the Plants Database (2005). He found the moth feeding on rattlebox in several different habitats in Gainesville throughout most of the year. Leguminosae (Fabaceae). With his trademark spectacles and safari hat, David Fairchild, known as the Indiana Jones of botany, traveled the world during the early 1900s in search of plants and collected thousands of exotics and new varieties, like pistachios, mangos, dates, cotton and wheat, and introduced them to the United States. Atlas of Florida Vascular Plants. 1987. Precopulatory sexual interaction in an arctiid moth (, Connor WE, Eisner T, Vander Meer RK, Guerrero A, Ghiringelli D, Meinwald J. Deer browse the stems and leaves. The life cycle of the ornate Bella Moth is short.. only three weeks. Since different plant species attract different butterflies, you need to choose the right host plants for the survival of caterpillars. Sourakov continued searching for bella moths feeding on Crotalaria in the Gainesville area. Females measure the HD concentration of males and use that information for selecting males with the potential to donate the most pyrrolizidine alkaloids in the spermatophore (Conner et al. But the bella moth relies on these particular alkaloids to produce chemical defenses and pheromones. Adult ornate bella moth, Utetheisa ornatrix (Linnaeus). Eisner T, Eisner M. 1991. Larva of the ornate bella moth, Utetheisa ornatrix (Linnaeus). It was praised by Fairchild and others as being an effective cover crop, which not only is able to enrich soil with nitrogen, but also is able to trap nematodes. The female herself also gains additional protection from predators due to the additional alkaloids from the male spermatophores (González et al. 3, Part 2. Figure 4. In the upland pine habitat behind the Florida Museum, Sourakov witnessed bella moths feeding on the exotic species C. lanceolata at the beginning of October two years in a row. The bella moth is one of the few insects that have evolved to use the Rattlebox as host due to the plants extreme toxicity (the plant is laced with pyrrolizidine alkaloids). “The moth has always fed on native species of Crotalaria,” said Sourakov, showing a drawer with hundreds of bella moth specimens that he reared in the lab. 1981, Connor et al. Cornell University Agricultural Experiment Station Memoir 329. Bella Moth Biology The Bella Moth is a colorful moth distributed throughout North and South America. 49, No. Ithaca, New York. The moths sequester these poisonous chemicals and thus become poisonous to predators. Crotalaria lanceolata and Crotalaria pallida both have extrafloral nectaries that are often visited in the Gainesville, Florida area by aggressive Florida carpenter ants, Camponotus floridanus (Buckley) (Figure 8), and red imported fire ants, Solenopsis invicta Buren. Host plants are believed to be limited to members of the Crotalaria (Rattlebox) family of plants, the larva stores the alkaloids it receives from these plants making it toxic to potential predators, a trait that carries over to the adult moth. “Horse and cattle folks know that these plants are poisonous to their livestock,” Sourakov said. Eisner T, Meinwald J. 1991), the pyrrolizidine alkaloids did not protectornate bella moth eggs from infection by the entomopathogenic fungi Beauveria bassiana (Bals. Eisner T, Eisner M, Rossini C, Iyengar VK, Roach BL, Benedikt E, Meinwald J. Whereas most arctiine larvae have verrucae (elevated wart-like areas on the cuticle) bearing many setae, Utetheisa larvae lack verrucae, and setae occur singly (Habeck 1987). Taming a wild plant may not sound too ominous, unless you are a tiny moth and the plant is 8 feet tall and poisonous. 1999) and Argiope florida Chamberlin & Ivie (Eisner et al. Ornate Bella Moth . 2010. The eggs are parasitized by the wasp Telenomus sp. If you want to see more of both butterflies and moths (Lepidoptera) in your yard, the addition of specific host plants is an empowering way to take an active role in supporting species diversity. 348-384. Three species of Crotalaria have become established and are common in Florida. Plants Database 2005. Adult ornate bella moths live approximately three weeks and females mate on average four to five times and as many as 13 times — each time receiving additional nutrients and alkaloids as nuptial gifts via the spermatophores. These plants produce pyrrolizidine alkaloids which are toxic to many species, but not the ornate bella moth. The Rattlebox and the bella moth's biology are intricately intertwined. Extrafloral nectaries as a deterrent mechanism against seed predators in the chemically protected weed. Courtship pheromone production and body size as correlates of larval diets in males of the arctiid moth, Connor WE, Eisner T, Vander Meer RK, Guerrero A, Meinwald J. Moths are attracted to gardens with a mix of plants that include grasses, flowers, shrubs and trees. Although a variety of plants in the family Fabaceae are listed in the literature as hosts for the ornate bella moth (Covell 2005, Robinson et al. He discovered the culprit was the bella moth, which he observed eating seeds from pods that grow on the plant. The caterpillars of Utetheisa ornatrix, the ornate bella moth, feed on host plants in the genus Crotalaria (Fabales: Fabaceae), which, in Florida, encompasses 4 native and 10 introduced species. Join me and my guest Dr. Andrei Sourakov as we discuss how bella moths have shifted their diets to include invasive rattlebox plants and how this host shift is keeping their invasion at bay. Please contact us for permission to use. 2nd edition. and records that cite several unspecified species (Rosa spp.) 2011}). The mature dried fruit of Crotalaria rattles like a rattle snake when the pods are shaken or blown by the wind. The larvae often feed upon and destroy the seeds, a positive when it comes to weedy invasive plants. Chemical basis of egg cannibalism in a caterpillar (, Bogner F, Eisner T. 1992. Ornate bella moth larvae sequester these chemicals and become poisonous (and usually repellent) to predators. Smooth rattlebox, Crotalaria pallida Aiton var. It should also contain mulch, not rock. Ferro VG, Guimarães PR, Trigo JR. 2006. Not self-fruitful. A moth friendly garden should be pesticide free. In his lab experiments with these plant species, which Sourakov propagated from seeds with the help of volunteers, the moth’s biology was shown to vary depending on the species of rattlebox plant used as food. Sexually transmitted chemical defense in a moth (=, Guimarães PR, Raimundo RL, Bottcher C, Silva RR, Trigo JR. 2006. Eggs have been demonstrated to be repellent to the spotted ladybird beetle Coleomegilla maculata DeGeer (Coleoptera: Coccinellidae) (Dussourd et al. Habit and habitat - Adult Bella moths concentrate around Rattlebox plants… For example Sun Hemp, Crotalaria juncea, which has been used in India as a crop since 600 B.C., is recommended by UF’s Institute of Food and Agricultural Sciences as “a summer cover crop for Florida growers because it returns nitrogen to the soil, suppresses weeds and nematodes, improves soil tilth and water-holding capacity, and reduces erosion in fields otherwise left without plant cover.”. Guimarães et al. In the laboratory, Utetheisa ornatrix male larvae developed faster and resulted in larger adults, when raised on Crotalaria incana vs. Crotalaria lanceolata (2 species native to Africa). Chapel Hill. The ornate bella moth has two generations northward but may breed continuously in the southernmost parts of its range (Covell 2005). The caterpillars of Utetheisa ornatrix, the ornate bella moth, feed on host plants in the genus Crotalaria (Fabales: Fabaceae), which, in Florida, encompasses 4 native and 10 introduced species. The additional nutrients allow the female to lay a larger number of eggs than would otherwise be possible. It is possible that the other host records are due to the habit of full-grown larvae to wander from the host plant (and often onto other species) prior to pupation. The University of North Carolina Press. Immature seeds contain approximately five times the amount of pyrrolizidine alkaloid as the foliage (Ferro et al. Criv.) Much of what we know about the biology of the ornate bella moth is due to the fascinating work of Thomas Eisner and his colleagues and graduate students. University of California Press. Males become active approximately 1 to 1½ hours after sunset and are attracted to females by a pulsed (Connor et al. Chapter 10. This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). These plants produce pyrrolizidine alkaloids which are toxic to many species, but not the ornate bella moth. Linnaeus (Linnei 1758) originally described two species in the genus Phalaena — ornatrix (more whitish or pale specimens) and bella (brightly colored specimens), and Hübner later moved them to the genus Utetheisa. However, cannibalism of pupae is minimized because larvae migrate off the host plant prior to pupation (Bogner & Eisner 1992). Asters come in a close second on our list of native caterpillar food plants. Apportionment of nuptial alkaloidal gifts by a multiply-mated female moth (, Bezzerides A, Yong T-H, Bezzerides J, Husseini J, Ladau J, Eisner M, Eisner T. 2004. The concentration of HD in the coremata is correlated with the amount of alkaloid carried by the males. and Paecilomyces lilacinus Thom (Now: Purpureocillium lilacinum [Thom] {Luangsa-Ard et al. After feeding briefly on foliage, the larvae move to the unripe pods which they bore into to feed on the seeds Upon reaching maturity, larvae migrate from the host plant to pupate in sheltered situations under loose bark on nearby trees, in thick vegetation, or in debris. Interesting, this native moth develops more quickly on native crotalaria species. In the laboratory, Utetheisa ornatrix male larvae developed faster and resulted in larger adults, when raised on Crotalaria incana vs. Crotalaria lanceolata (2 species native to Africa). Figure 5. Powell JA, Opler PA. 2009. All photographs are copywrited property. He’s observed the introduction of several rattlebox species, all with different morphology, ecology and chemistry, has resulted in a substantial expansion of the bella moth’s habitat and activity patterns. Regnum Animale. Bella Moth underwings. 2016, LaMunyon & Eisner 1993). Creating a list of host plants is the first step towards planning a butterfly garden. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. 2015. Final instar larva. “They affect their livers and their alkaloids even have been found to have DNA damaging effects.”. This work is summarized in his book, For Love of Insects (Eisner 2003, Chapter 10). Moth host (bumblebee clearwing). Chemical basis of pupal cannibalism in a caterpillar (. Furthermore, females are able to control which sperm fertilize the eggs, and those from larger males are more likely to fertilize the eggs (Egan et al. Upon hatching, the young larvae feed on the foliage. thanks. 1990). utethesia bella hi, you may not remember me i sent you a few pictures about maybe 4 months ago of three different caterpillars, one of them was utethesia bella which i was able to take a picture of on it’s host plant, the photo is attached, and recently i found another caterpillar, i hope this image is a little clearer than the others were. These are Crotalaria lanceolata E. Mey. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. Figure 3. But a nearby patch of native C. pumila became the new site of larval development for the moth. The Bella moths wing pattern is extremely variable, it is however the only moth in Florida that has a pink and yellow forewing with rows of black spots ringed in white. The Lepidoptera of New York and neighboring states. During oviposition, the female contributes not only her own alkaloids, but also those received from the male to her eggs making the eggs even more toxic to potential predators. Unlike most moths Bella are active during the day. In laboratory studies, young larvae fed on foliage of native species of Crotalaria developed faster than those fed on foliage of exotic species (Sourakov 2015). Originating from South America (Brazil, Argentina, Paraguay, Uraguay), this an incredibly invasive weed that causes problems both in home gardens and in Native Bush. 1999). There are distinct white spots on the anterior and posterior margins of the black bands. Special Publication Number 12. (Report) by "Florida Entomologist"; Biological sciences Beans Diseases and pests Physiological aspects Insect-plant relationships Research Legumes Mimosaceae Moths Health aspects A flower spike of lanceleaf rattlebox, Crotalaria lanceolata E. Mey, with carpenter ants feeding at extrafloral nectaries. 2005. Vuill. Credits: Don Hall, UF/IFAS Figure 8. Iyengar VK, Eisner T. 1999a. The name Crotalaria originates from the Greek root "crotal" which means "a rattle". “Eradicating a foreign species that has established is very difficult if not impossible.”. Contact … (Report) by "Florida Entomologist"; Biological sciences Beans Diseases and pests Physiological aspects Insect-plant relationships Research Legumes Mimosaceae Moths Health aspects Sarasota, Florida. Higher HD alkaloid levels in males is correlated with larger body size which is a heritable trait (Iyengar & Eisner 1999a&b). The lightly consumed C. retusa nearby became the new host plant, allowing the moth to continue to persist through December. The male then lands beside her and copulates. Credits: Don Hall, UF/IFAS Figure 9. 1983. An Index to the Described Life Histories, Early Stages and Hosts of the Macrolepidoptera of the Continental United States and Canada. A hit was the harmless hand capture and release of on of the beautiful gold, white, black, and vivid pink Bella Moth (often called Rattlebox Moth for its host plant). obovata (G. Don) Pohill (formerly Crotalaria mucronata Desv.) Plant-derived pyrrolizidine alkaloid protects eggs of a moth (, Bogner F, Eisner T. 1991. The mechanism by which females control the flow of sperm is unknown, but LaMunyon & Eisner (1993) hypothesized that females make the decision based on the degree of distension of the bursa copulatrix (insect vagina) by each spermatophore. The pheromone also contains diene and tetraene forms (two and four double bonds, respectively) (Connor et al. Free Online Library: Exotic Crotalaria species (Fabales: Fabaceae) as host plants of the ornate Bella moth, Utetheisa ornatrix (Lepidoptera: Erebidae), in Florida: laboratory biology. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. 39-40, pp. 1980. This brightly colored moth gets toxic alkaloids from its host plant, and the alkaloid content tends to be higher in showy rattlebox than in the native species. This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). However, the native and exotic species have very different habitat preferences, and seasonal patterns of growth.”. with wings spread. 1981. Martinsville, Virginia.
