Since different plant species attract different butterflies, you need to choose the right host plants for the survival of caterpillars. pp. Ornate Bella Moth . Interesting, this native moth develops more quickly on native crotalaria species. Unpalatability of the pyrrolizidine alkaloid containing moth. Back to Family Page. Plant-derived pyrrolizidine alkaloid protects eggs of a moth (, Bogner F, Eisner T. 1991. Chapter 62. pp. Connor WE, Roach B, Benedict E, Meinwald J, Eisner T. 1990. 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. Not self-fruitful. Chemical basis of pupal cannibalism in a caterpillar (. But the bella moth relies on these particular alkaloids to produce chemical defenses and pheromones. Higher HD alkaloid levels in males is correlated with larger body size which is a heritable trait (Iyengar & Eisner 1999a&b). 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 mature dried fruit of Crotalaria rattles like a rattle snake when the pods are shaken or blown by the wind. 930348.00 – 8105 – Utetheisa ornatrix – Ornate Bella Moth – (Linnaeus, 1758) Photographs are the copyrighted property of each photographer listed. A year later, he noticed the seasonal plant had dwindled more than 90 percent. The concentration of HD in the coremata is correlated with the amount of alkaloid carried by the males. Today, the plant would control many Florida habitats if it weren’t for the tiny pinkish-red ornate bella moth keeping it at bay. Iyengar VK, Eisner T. 1999a. Need two plants to cross-pollinate. Bella Moth Biology The Bella Moth is a colorful moth distributed throughout North and South America. Deer browse the stems and leaves. 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. obovata (G. Don) Pohill (formerly Crotalaria mucronata Desv.) and Crotalaria pallida Aiton var. 1997. 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 more common "bella" form has the front wings yellow with white bands each containing a row of black dots, and the hindwings bright pink with an irregular marginal black band (Figures 5 and 6). Species Pages. Larvae: The larvae are orange-brown with broad irregular black bands on each segment (Figure 3). 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. (2006) reported that Utetheisa ornatrix larvae were repulsed from the racemes of Crotalaria pallida by ants attracted to the extrafloral nectaries but that predation on the larvae was rare. Fairchild’s writings suggest a variety of exotic rattlebox plants in the genus Crotalaria were introduced to South Florida about 100 years ago. Adult and larva of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 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). Photograph by Don Hall, Entomology and Nematology Department, University of Florida. Powell JA, Opler PA. 2009. Many other species of Crotalaria were introduced into the southeastern U.S. 55-65 years ago for soil improvement and forage. Only four species of Crotalaria are native to the southeastern U.S. of which two occur in Florid… Photograph by Don Hall, Entomology and Nematology Department, University of Florida. Crotalaria plants (particularly the immature seeds) are laced with pyrrolizidine alkaloids. 2016. The University of North Carolina Press. This work is summarized in his book, For Love of Insects (Eisner 2003, Chapter 10). In the laboratory, Utetheisa ornatrix male larvae developed faster and resulted in It is also found through Mexico and southward through Central (Powell & Opler 2009) and South America all the way to Argentina (Pease 1968) and throughout most of the Antilles (North American Moth Photographers Group Undated). Part IV. The life cycle of the ornate Bella Moth is short.. only three weeks. This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). A Field Guide to Moths of Eastern North America. Please contact us for permission to use. Alkaloid content of parasitoids reared from pupae of an alkaloid-sequestering arctiid moth (. Cannibalistic caterpillars (. Florida has ten exotic species, including Crotalaira spectabilis, and four native species of the poisonous rattlebox, all of which the bella moth successfully keeps at bay. Contact … Rattlebox moth is our favorite, because it reflects the relationship between the bug and the group, or genus of plants called Crotalaria, on which it depends for survival. It’s a vigorous slender evergreen vine that … Cornell University Agricultural Experiment Station Memoir 329. 286-291. Vuill. (For chemical structures of Utetheisa ornatrix pheromones, see El-Sayed (2014). (Report) by "Florida Entomologist"; Biological sciences Beans Diseases and pests Physiological aspects Insect-plant relationships Research Legumes Mimosaceae Moths Health aspects Figure 6. Covell CV. 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. Moths are attracted to gardens with a mix of plants that include grasses, flowers, shrubs and trees. thanks. 2006). 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. North American Moth Photographers Group (, Pease R. 1968.

The male then lands beside her and copulates. 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.”. Eisner T, Eisner M, Siegler M. 2005. A moth friendly garden should be pesticide free. 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. Polyandrous females provide sons with more competitive sperm: Support for the sexy-sperm hypothesis in the rattlebox moth (. 1972. ), with flowers and fruit. The bella moth was eating the plant's poisonous seeds, which help it produce chemical defenses that make the moths and their eggs unpalatable to would-be predators. Eggs of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 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. Chemical basis of egg cannibalism in a caterpillar (, Bogner F, Eisner T. 1992. For further information on Crotalaria species, see Isley (1990), Wunderlin and Hansen (2003), Wunderlin et al. Chapel Hill. Immature seeds contain approximately five times the amount of pyrrolizidine alkaloid as the foliage (Ferro et al. Sex attractant of an arctiid moth (. 2011}). 1960. 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). (Report) by "Florida Entomologist"; Biological sciences Beans Diseases and pests Physiological aspects Insect-plant relationships Research Legumes Mimosaceae Moths Health aspects In addition to sperm, males also transfer nutrients and HD to the female during mating via the spermatophore. 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. Records that list just a plant genus as host (eg Rosa), records that cite one unidentified species (Rosa sp.) Figure 2. 1988), the green lacewing Ceraeochrysa cubana (Hagan) (Neuroptera: Chrysopidae) (Eisner et al. Also known as Moth Plant, Kapok Vine, Araujia Sericifera. 2005, Eisner & Meinwald 1995). Isley D. 1990.Vascular Flora of the Southeastern United States. Photograph by Lary Reeves, Entomology and Nematology Department, University of Florida. “They can’t tell the difference between the native and the invasive species. Sourakov has taken research of Eisner and his colleagues forward, out of the lab and into the real world. These plants produce pyrrolizidine alkaloids which are toxic to many species, but not the ornate bella moth. The moths sequester these poisonous chemicals and thus become poisonous to predators. 1981, Dussourd et al. (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. Atlas of Florida Vascular Plants. The eggs are parasitized by the wasp Telenomus sp. Smooth rattlebox, Crotalaria pallida Aiton var. 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. 1999) and Argiope florida Chamberlin & Ivie (Eisner et al. Leguminosae (Fabaceae). 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). Vol. which are both native to Africa and Crotalaria spectabilis Roth which is native to Asia. The biology of the ornate bella moth is intricately intertwined with its Crotalaria host plants. Regnum Animale. Precopulatory sexual interaction in an arctiid moth (, Connor WE, Eisner T, Vander Meer RK, Guerrero A, Ghiringelli D, Meinwald J. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. The Pherobase: Database of Insect Pheromones and Semiochemicals. Adults are concentrated in patches of Crotalaria. 2000. It was Eisner who noticed the alkaloids that allow the bella moths to flourish are poisonous to some other bugs, including spiders. Credits: Don Hall, UF/IFAS Figure 9. In northern regions, Bella moths play an important role in controlling these toxic plant populations by feeding on the plant seeds, thereby reducing plant reproduction and benefiting livestock and farmers. 2003. Ithaca, New York. Habeck DH. “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. Chapter 10. Moth host (bumblebee clearwing). Sourakov continued searching for bella moths feeding on Crotalaria in the Gainesville area. Figure 9. Heritability of body mass, a sexually selected trait in an arctiid moth (, Iyengar VK, Rossini C, Eisner T. 2001. 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. “Once a species is introduced, they may take on a life of their own,” said Sourakov, collections coordinator at the museum’s McGuire Center for Lepidoptera and Biodiversity on the University of Florida campus. Why do larvae of, El-Sayed AM 2014. plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). All photographs are copywrited property. Sourakov, with the help of UF undergraduate students, is now continuing to explore the ongoing coevolution of plants and moths. The female herself also gains additional protection from predators due to the additional alkaloids from the male spermatophores (González et al. 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.”. 2nd edition. Utetheisa ornatrix, also called the bella moth, ornate moth or rattlebox moth is a moth of the subfamily Arctiinae.It is aposematically colored ranging from pink, red, orange and yellow to white coloration with black markings arranged in varying patterns on its wings. 538-542. 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. 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. The ornate bella moth has two generations northward but may breed continuously in the southernmost parts of its range (Covell 2005). 1991, Iyengar et al. 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 larger spermatophores of larger males would cause greater distension of the bursa. Larva of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 496 pp. Though such occurrences are rare, the health concerns prompted testing of some products for Pyrrolizidine alkaloids – the harmful components of Crotalaria. 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. The woolybears, tiger moth larvae. 2000),and the cavity-nesting ant, Leptothorax longispinosus Roger (Now Temnothorax longispinosus [Roger]) (Hare & Eisner 1993). The Rattlebox and the bella moth's biology are intricately intertwined. The pupae are encased in a brown and black sac covered in a light coat of silk. It is also known as the spicebush silkmoth, which refers to is one of the promethea silkmoth's common host plants, spicebush (Lindera benzoin). Gmel.). A flower spike of lanceleaf rattlebox, Crotalaria lanceolata E. Mey, with carpenter ants feeding at extrafloral nectaries. LaMunyon CW. Agaristidae through Nymphalidae, including butterflies. Hare JF, Eisner T. 1993. Eisner T, Eisner M. 1991. are treated as generic only. System Naturae. “Eradicating a foreign species that has established is very difficult if not impossible.”. “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. Extrafloral nectaries as a deterrent mechanism against seed predators in the chemically protected weed. Guimarães et al. (In Latin). The alkaloids are retained in the pupal and adult stages and are ultimately passed on to the eggs. Therefore, by selecting males with higher gifts of HD alkaloid, females are simultaneously selecting for increased male body size â a trait that will be passed on to her progeny. Upon hatching, the young larvae feed on the foliage. Dussourd DE, Harvis CA, Meinwald J, Eisner T. 1991. 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). Increased fecundity, as a function of multiple mating, in an arctiid moth, LaMunyon CW, Eisner T. 1993. The chemistry of sexual selection. Originating from South America (Brazil, Argentina, Paraguay, Uraguay), this an incredibly invasive weed that causes problems both in home gardens and in Native Bush. Moths of Western North America. Adults: The adult ornate bella moth is a rather small moth (wingspan 3.0 to 4.5 cm). Chemical defense against predation in an insect egg. Sourakov’s research follows in the footsteps of the late Thomas Eisner, a Cornell University scientist who became known as the father of chemical ecology. Today, some Crotalaria plants are still used as cover crops in the United States (mostly in the South), and around the world. 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. Lepidopterist Andrei Sourakov with the Florida Museum of Natural History has been studying ornate bella moths, Utetheisa ornatrix, since 2010. (Hymenoptera: Scelionidae) (Bezzerides et al. Ferro VG, Guimarães PR, Trigo JR. 2006. Hummingbirds and butterflies are attracted to the nectar produced by the flowers while birds and small mammals eat the fruit. Photo by Don Hall from the UF/IFAS featured creatures website. University Press of Florida. The Lepidoptera of New York and neighboring states. Also, the following six species of parasitoids have been reared from Utetheisa ornatrix pupae by Rossini et al. 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. Creating a list of host plants is the first step towards planning a butterfly garden. Today, the plant would control many Florida habitats if it weren’t for the tiny pinkish-red ornate bella moth keeping it at bay. An Index to the Described Life Histories, Early Stages and Hosts of the Macrolepidoptera of the Continental United States and Canada. Unlike most moths, which are nocturnal, the ornate bella moth is diurnal and flies readily when disturbed. Much of what we know about the biology of the ornate bella moth is due to the fascinating work of Thomas Eisner and … Criv.) Pupae: The pupae are black with irregular orange-brown bands and are covered with a loose layer of silk (Figure 4). 2016. 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. 1999). Evolution and hybridization in the. “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. A native species of moth does a good job of keeping these plants under control, and provides a great research model for me and my students.”. He found the moth feeding on rattlebox in several different habitats in Gainesville throughout most of the year.
