(In Latin). 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. Rampant, evergreen vine growing up to 8 m tall with smelly, milky sap and twining flexible stems that are covered in down and woody near the base. “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. The female herself also gains additional protection from predators due to the additional alkaloids from the male spermatophores (González et al. 1999) and Argiope florida Chamberlin & Ivie (Eisner et al. There are distinct white spots on the anterior and posterior margins of the black bands. 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 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. Flip Through . LaMunyon CW. Smooth rattlebox, Crotalaria pallida Aiton var. Back to Family Page. Getty Images/Kevin Dutton. Figure 9. 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. Sourakov A. “They can’t tell the difference between the native and the invasive species. His pioneering lab experiments involving bella moths revealed how insects use chemicals to attract mates as well as prey, and elude predators. Credits: Don Hall, UF/IFAS Figure 8. These plants produce pyrrolizidine alkaloids which are toxic to many species, but not the ornate bella moth. Eisner T, Meinwald J. 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. Postcopulatory sexual selection in an arctiid moth (, Linnei C. 1758. A common native host plant for these moths is the Crotalaria avonensis, a beautiful plant with yellow flowers. The children were able to see the contrasting colorful spoonbill pink hindwings and how they are hidden at repose by the camouflage patterned forewings. Unlike most moths, which are nocturnal, the ornate bella moth is diurnal and flies readily when disturbed. Also known as Moth Plant, Kapok Vine, Araujia Sericifera. (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. 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. Leguminosae (Fabaceae). Eggs are laid in clusters on the foliage. “Eradicating a foreign species that has established is very difficult if not impossible.”. with wings spread. However, cannibalism of pupae is minimized because larvae migrate off the host plant prior to pupation (Bogner & Eisner 1992). Three species of Crotalaria have become established and are common in Florida. Immature seeds contain approximately five times the amount of pyrrolizidine alkaloid as the foliage (Ferro et al. 1990). Though such occurrences are rare, the health concerns prompted testing of some products for Pyrrolizidine alkaloids – the harmful components of Crotalaria. 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. Atlas of Florida Vascular Plants. (Report) by "Florida Entomologist"; Biological sciences Beans Diseases and pests Physiological aspects Insect-plant relationships Research Legumes Mimosaceae Moths Health aspects Creating a list of host plants is the first step towards planning a butterfly garden. The male then lands beside her and copulates. 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). 1960. The ornate bella moth, Utetheisa ornatrix (Linnaeus), is one of our most beautiful moths (Figure 1). This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 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. 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. 2016, LaMunyon & Eisner 1993). Interesting, this native moth develops more quickly on native crotalaria species. Gmel.). 1991, Iyengar et al. obovata (G. Don) Pohill (formerly Crotalaria mucronata Desv.) It was Eisner who noticed the alkaloids that allow the bella moths to flourish are poisonous to some other bugs, including spiders. Figure 7. ), with flowers and fruit. This allows it to be witnessed more frequently than other moths, which are mostly modestly colored and nocturnal. A moth friendly garden should be pesticide free. Males become active approximately 1 to 1½ hours after sunset and are attracted to females by a pulsed (Connor et al. Photo by Don Hall from the UF/IFAS featured creatures website. Adult ornate bella moth, Utetheisa ornatrix (Linnaeus). The University of North Carolina Press. Hare JF, Eisner T. 1993. 1997. Pupa of the ornate bella moth, Utetheisa ornatrix (Linnaeus). Eggs have been demonstrated to be repellent to the spotted ladybird beetle Coleomegilla maculata DeGeer (Coleoptera: Coccinellidae) (Dussourd et al. Fun for children of all ages. 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. Arctiidae (Noctuoidea). Habeck DH. Credits: Don Hall, UF/IFAS Figure 9. Cannibalistic caterpillars (. A flower spike of lanceleaf rattlebox, Crotalaria lanceolata E. Mey, with carpenter ants feeding at extrafloral nectaries. However, the native and exotic species have very different habitat preferences, and seasonal patterns of growth.”. Alkaloid content of parasitoids reared from pupae of an alkaloid-sequestering arctiid moth (. Polyene pheromone components from an arctiid moth (. The seeds contain alkaloids that are poisonous to some insects and other animals. and Paecilomyces lilacinus Thom (Now: Purpureocillium lilacinum [Thom] {Luangsa-Ard et al. Higher HD alkaloid levels in males is correlated with larger body size which is a heritable trait (Iyengar & Eisner 1999a&b). Moths of Western North America. The ornate bella moth has two generations northward but may breed continuously in the southernmost parts of its range (Covell 2005). Pyrrolizidine alkaloid deters ant predators of, Hare JF, Eisner T. 1995. 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. Because most of our common Crotalarias are introduced weedy species and toxic to cattle, the ornate bella moth plays a beneficial role by eating their seeds and suppressing their reproduction. Only four species of Crotalaria are native to the southeastern U.S. of which two occur in Florida — Avon Park rattlebox (Crotalaria avonensis DeLaney & Wunderlin), which is restricted to Florida, and rabbitbells (Crotalaria rotundifolia J.F. Not self-fruitful. Part IV. Lipsiae, sumptibus Guilielmi Engelmann, 1894. The sweet smell of success. 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). 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). Adults are concentrated in patches of Crotalaria. 1980) sex attractant pheromone - composed primarily of the 21 carbon triene (3 double bonds) chemical Z,Z,Z-3,6,9-heneicosatriene originating from glands at the tip of the female's abdomen. are treated as generic only. Eggs: The eggs are white to yellow and spherical (Figure 2). In the U.S., it is more common in the southern part of its range. 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. Round, fleshy, orange to red berries appear in late summer. 2nd edition. Unpalatability of the pyrrolizidine alkaloid containing moth. 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. 2005. Therefore, it is more commonly seen than nocturnal species of moths by the public. Back to Species List. Precopulatory assessment of male quality in an arctiid moth (, Jain SC, Doussard DE, Conner WE, Eisner T, Guerrero A, Meinwald J. Given the opportunity, ornate bella moth larvae are cannibalistic on conspecific eggs (Bogner & Eisner 1991, Hare & Eisner 1995) and pupae (Bogner & Eisner 1992). 3, Part 2. 348-384. Eisner T, Eisner M, Rossini C, Iyengar VK, Roach BL, Benedikt E, Meinwald J. 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), the jumping spider Phidippus audax (Hentz) (Eisner & Eisner 1991), and the orb weaving spiders .Trichonephila clavipes (Linnaeus) (Eisner & Eisner 1991, González et al. 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. Pictured on the flower of an exotic Crotalaria retusa, a tiny ornate bella moth, Utetheisa ornatrix, is changing its ecology as it adjusts to feeding on the seeds of this invasive plant. 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.”. His March 2015 study appearing in the Journal of Natural History reveals that the moth is changing its ecology, co-evolving as it adjusts to feeding on the seeds of several invasive exotic plant species. 1980, Jain et al. Polyandrous females provide sons with more competitive sperm: Support for the sexy-sperm hypothesis in the rattlebox moth (. Plant clippings and fallen leaves should be allowed to accumulate a little for safe hiding spots for moths … 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. plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 369 pp. Special Publication Number 12. Iyengar VK, Eisner T. 1999a. Vuill. 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. Much of what we know about the biology of the ornate bella moth is due to the fascinating work of Thomas Eisner and … Photograph by Don Hall, Entomology and Nematology Department, University of Florida. These are Crotalaria lanceolata E. Mey. Proceedings of the National Academy of Sciences USA 97: 1634-1639. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. Bella Moth Biology The Bella Moth is a colorful moth distributed throughout North and South America. Chapter 10. 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. 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). The larvae often feed upon and destroy the seeds, a positive when it comes to weedy invasive plants. This is a fascinating discussion about the ecological consequences of invasive plant introductions. It has a wingspan of 33–46 mm. Today in Florida, these exotic species often grow on abandoned farmland that has transformed into forest. 2004). But by late November each year, the plant had nearly disappeared. Connor WE, Roach B, Benedict E, Meinwald J, Eisner T. 1990. 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. 1. Eisner T, Eisner M, Siegler M. 2005. Callosamia promethea, commonly known as the promethea silkmoth, is a member of the family Saturniidae, which contains approximately 1,300 species. Final instar larva. Luangsa-Ard J, Houbraken J, van Doorn T, Hong SB, Borman AM, Hywel-Jones NL, Samson RA. pp. Larvae: The larvae are orange-brown with broad irregular black bands on each segment (Figure 3). Eisner’s lab experiments showed female bella moths are attracted to the same toxins in potential mates. Bella Moth underwings. Pupae: The pupae are black with irregular orange-brown bands and are covered with a loose layer of silk (Figure 4). I was surprised to find this moth in my yard because I don’t have the host plant for it, which is any number of species of wildflower in the genus Crotalaria, called … Bezzerides and Eisner (2002) have demonstrated that individual eggs from multiply-mated females receive alkaloids from more than one male. 2000),and the cavity-nesting ant, Leptothorax longispinosus Roger (Now Temnothorax longispinosus [Roger]) (Hare & Eisner 1993). Leaves are green, hairless and dull on the top, and downy and paler grey/green underneath. 1981, Dussourd et al. 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 eggs are parasitized by the wasp Telenomus sp. A plant name found only in Index Kewensis is in all probability archaic and such names are indicated where they occur below. Among them is Crotalaria spectabilis, showy rattlebox, which particularly stands out with its 6- to 8 feet-tall plants and beautiful yellow flowers. Also, the following six species of parasitoids have been reared from Utetheisa ornatrix pupae by Rossini et al. By late November, the plant was nearly dead. 2005, Eisner & Meinwald 1995). Originating from South America (Brazil, Argentina, Paraguay, Uraguay), this an incredibly invasive weed that causes problems both in home gardens and in Native Bush. An Index to the Described Life Histories, Early Stages and Hosts of the Macrolepidoptera of the Continental United States and Canada. Meanwhile, in Cross Creek, the moths start flying as early as March, laying eggs on the early sprouts of the native C. rotundifolia. 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. Taming a wild plant may not sound too ominous, unless you are a tiny moth and the plant is 8 feet tall and poisonous. 1987. 2000. Unfortunately, species of Crotalaria are toxic to livestock due to the presence of pyrrolizidine alkaloids, and are potentially fatal. 10 ) of silk ( Figure 1 ) van Doorn T, Eisner T. 1999b repellent to the toxins.
