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. Eisner T, Eisner M, Siegler M. 2005. 1999) and Argiope florida Chamberlin & Ivie (Eisner et al. 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. (For chemical structures of Utetheisa ornatrix pheromones, see El-Sayed (2014). ), with flowers and fruit. In the U.S., it is more common in the southern part of its range. These plants produce pyrrolizidine alkaloids which are toxic to many species, but not the ornate bella moth. Agaristidae through Nymphalidae, including butterflies. Freshly emerged adult. The male then lands beside her and copulates. Learn more about the McGuire Center for Lepidoptera & Biodiversity at the Florida Museum. Sourakov has taken research of Eisner and his colleagues forward, out of the lab and into the real world. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. 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. “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. 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. 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). You are what you eat: native versus exotic Crotalaria species (Fabaceae) as host plants of the ornate bella moth, Storey GK, Aneshanslely DJ, Eisner T. 1991. (Report) by "Florida Entomologist"; Biological sciences Beans Diseases and pests Physiological aspects Insect-plant relationships Research Legumes Mimosaceae Moths Health aspects Parentally provided alkaloid does not protect eggs of. University of California Press. 2000. Evolution and hybridization in the. Proceedings of the National Academy of Science USA. Gmel.). Leaves are arrowhead-like in shape (3-12 x 2-6 cm) and alternate on the stems. Adults are concentrated in patches of Crotalaria. 2016, LaMunyon & Eisner 1993). McGuire Center for Lepidoptera & Biodiversity. 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. 49, No. 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. 1997. Sarasota, Florida. Covell CV. 2005. Bella Moth - Utetheisa ornatrix Bella or Rattlebox Moths are one of the most colorful moths found in Florida. Chapter 10. Connor WE, Roach B, Benedict E, Meinwald J, Eisner T. 1990. 1999), the jumping spider Phidippus audax (Hentz) (Eisner & Eisner 1991), and the orb weaving spiders .Trichonephila clavipes (Linnaeus) (Eisner & Eisner 1991, González et al. Isley D. 1990.Vascular Flora of the Southeastern United States. System Naturae. 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. It is the same root word as used in the genus name for rattle snakes, Crotalus. 930348.00 – 8105 – Utetheisa ornatrix – Ornate Bella Moth – (Linnaeus, 1758) Photographs are the copyrighted property of each photographer listed. Ornate Bella Moth . 1991), the pyrrolizidine alkaloids did not protectornate bella moth eggs from infection by the entomopathogenic fungi Beauveria bassiana (Bals. In northern regions, 496 pp. Extrafloral nectaries as a deterrent mechanism against seed predators in the chemically protected weed. 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. A Field Guide to Moths of Eastern North America. 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). 1987. Florida Museum of Natural History photo by Andrei Sourakov. 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. 369 pp. (Report) by "Florida Entomologist"; Biological sciences Beans Diseases and pests Physiological aspects Insect-plant relationships Research Legumes Mimosaceae Moths Health aspects Lanceleaf rattlebox, Crotalaria lanceolata E. Mey, in fruit. 3, Part 2. 1972. Therefore, by selecting males with higher gifts of HD alkaloid, females are simultaneously selecting for increased male body size – a trait that will be passed on to her progeny. Figure 3. Ornate bella moth larvae sequester these chemicals and become poisonous (and usually repellent) to predators. 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. Robinson GS, Ackery PR, Kitching IJ, Beccaloni GW, Hernández LM. LaMunyon CW. But the bella moth relies on these particular alkaloids to produce chemical defenses and pheromones. The additional nutrients allow the female to lay a larger number of eggs than would otherwise be possible. 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. 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 sweet smell of success. Figure 9. The pupae are encased in a brown and black sac covered in a light coat of silk. 1980. A moth friendly garden should be pesticide free. Smooth rattlebox, Crotalaria pallida Aiton var. There are distinct white spots on the anterior and posterior margins of the black bands. Higher HD alkaloid levels in males is correlated with larger body size which is a heritable trait (Iyengar & Eisner 1999a&b). Eggs of the ornate bella moth, Utetheisa ornatrix (Linnaeus). Habit and habitat - Adult Bella moths concentrate around Rattlebox plants… 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. All photographs are copywrited property. http://www.pherobase.com/database/species/species-Utetheisa-ornatrix.php, http://mothphotographersgroup.msstate.edu/species.php?hodges=8105, HOSTS - a Database of the World's Lepidopteran Hostplants, Bezzerides A, Eisner T. 2002. 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. Powell JA, Opler PA. 2009. This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 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. 2016. Sourakov continued searching for bella moths feeding on Crotalaria in the Gainesville area. The Bella Moth is a colorful moth distributed throughout North and South America. Eisner T, Eisner M, Rossini C, Iyengar VK, Roach BL, Benedikt E, Meinwald J. (2016) and the Plants Database (2005). A plant name found only in Index Kewensis is in all probability archaic and such names are indicated where they occur below. “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. Today, some Crotalaria plants are still used as cover crops in the United States (mostly in the South), and around the world. 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. The male even shares some of the toxic chemical with the female during mating, which in turn makes her eggs taste disgusting to other insects. Showy rattlebox, Crotalaria spectabilis Roth., a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 1980, Jain et al. The children were able to see the contrasting colorful spoonbill pink hindwings and how they are hidden at repose by the camouflage patterned forewings. Wunderlin RP, Hansen BF, Franck AR, Essig FB. Figure 7. Female choice increases offspring fitness in an arctiid moth (, Iyengar VK, Eisner T. 1999b. Credits: Don Hall, UF/IFAS Figure 8. 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 bella moth measures less than 2 inches, but it is vibrantly colored and active during the day and night. Three species of Crotalaria have become established and are common in Florida. 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. 1981. Plants Database 2005. 1988), the green lacewing Ceraeochrysa cubana (Hagan) (Neuroptera: Chrysopidae) (Eisner et al. 1999). Plant-derived pyrrolizidine alkaloid protects eggs of a moth (, Bogner F, Eisner T. 1991. The alkaloids are retained in the pupal and adult stages and are ultimately passed on to the eggs. Special Publication Number 12. The pheromone also contains diene and tetraene forms (two and four double bonds, respectively) (Connor et al. Figure 10. 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. Only four species of Crotalaria are native to the southeastern U.S. of which two occur in Florid… which are both native to Africa and Crotalaria spectabilis Roth which is native to Asia. 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. 2nd edition. Flip Through . A flower spike of lanceleaf rattlebox, Crotalaria lanceolata E. Mey, with carpenter ants feeding at extrafloral nectaries. It’s a vigorous slender evergreen vine that … and records that cite several unspecified species (Rosa spp.) Meanwhile, in Cross Creek, the moths start flying as early as March, laying eggs on the early sprouts of the native C. rotundifolia. Photograph by Lary Reeves, Entomology and Nematology Department, University of Florida. 2397-2415. This allows it to be witnessed more frequently than other moths, which are mostly modestly colored and nocturnal. Upon hatching, the young larvae feed on the foliage. “They can’t tell the difference between the native and the invasive species. 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. Unfortunately, species of Crotalaria are toxic to livestock due to the presence of pyrrolizidine alkaloids, and are potentially fatal. Moth Vine Plant. 1960. This work is summarized in his book, For Love of Insects (Eisner 2003, Chapter 10). Arctiidae (Noctuoidea). Guimarães et al. In addition to sperm, males also transfer nutrients and HD to the female during mating via the spermatophore. Sourakov, with the help of UF undergraduate students, is now continuing to explore the ongoing coevolution of plants and moths. 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. Immature seeds contain approximately five times the amount of pyrrolizidine alkaloid as the foliage (Ferro et al. Taming a wild plant may not sound too ominous, unless you are a tiny moth and the plant is 8 feet tall and poisonous. Bella Moth Biology The Bella Moth is a colorful moth distributed throughout North and South America. Cornell University Agricultural Experiment Station Memoir 329. Fanning the female with the coremata stimulates her to raise her wings exposing her abdomen. 1995. A common native host plant for these moths is the Crotalaria avonensis, a beautiful plant with yellow flowers. Semiochemicals of. Moths are attracted to gardens with a mix of plants that include grasses, flowers, shrubs and trees. 1990). Larva of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 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. 2016. 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. It should also contain mulch, not rock. 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. 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. Vol. 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. 2005, Eisner & Meinwald 1995). Credits: Don Hall, UF/IFAS Figure 9. 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). Getty Images/Kevin Dutton. 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. 2004). Alkaloid content of parasitoids reared from pupae of an alkaloid-sequestering arctiid moth (. He found the moth feeding on rattlebox in several different habitats in Gainesville throughout most of the year. However, the native and exotic species have very different habitat preferences, and seasonal patterns of growth.”. Many other species of Crotalaria were introduced into the southeastern U.S. 55-65 years ago for soil improvement and forage. “Eradicating a foreign species that has established is very difficult if not impossible.”. 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. Creating a list of host plants is the first step towards planning a butterfly garden. Fun for children of all ages. It is also known as the spicebush silkmoth, which refers to is one of the promethea silkmoth's common host plants, spicebush (Lindera benzoin). Back to Species List. Criv.) Rossini C, Hoebeke ER, Iyengar VK, Conner WE, Eisner M, Eisner T. 2000. North American Moth Photographers Group (, Pease R. 1968. Males become active approximately 1 to 1½ hours after sunset and are attracted to females by a pulsed (Connor et al. It was Eisner who noticed the alkaloids that allow the bella moths to flourish are poisonous to some other bugs, including spiders. The pupae are encased in a brown and black sac covered in a light coat of silk. 2000),and the cavity-nesting ant, Leptothorax longispinosus Roger (Now Temnothorax longispinosus [Roger]) (Hare & Eisner 1993). The woolybears, tiger moth larvae. The chemistry of sexual selection. The larvae often feed upon and destroy the seeds, a positive when it comes to weedy invasive plants. 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. Crotalaria plants (particularly the immature seeds) are laced with pyrrolizidine alkaloids. Bezzerides and Eisner (2002) have demonstrated that individual eggs from multiply-mated females receive alkaloids from more than one male. Originating from South America (Brazil, Argentina, Paraguay, Uraguay), this an incredibly invasive weed that causes problems both in home gardens and in Native Bush. 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 Rattlebox and the bella moth's biology are intricately intertwined. 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. 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. Ferro VG, Guimarães PR, Trigo JR. 2006. University Press of Florida. Asters come in a close second on our list of native caterpillar food plants. Figure 4. Today in Florida, these exotic species often grow on abandoned farmland that has transformed into forest. (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. Virginia Museum of Natural History. The eggs are parasitized by the wasp Telenomus sp. Full-grown larvae are 30-35 mm in length. Predators: All life stages of ornate bella moths are protected from a wide range of predators by the alkaloids sequestered from their host plants. 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.”. United States Department of Agriculture. Adult ornate bella moths are rejected by the wolf spider Lycosa ceratiola Gertsch (Eisner & Eisner 1991, González et al. Passion flower, Passiflora caerulea, is an exotic-looking climber, bearing evergreen, deeply lobed, dark green glossy leaves, from which large white flowers with central filaments of purple, blue and white appear from July to September, followed by egg-shaped, orange-yellow fruit. Adults are approximately 1.5 inches in wingspan. Forbes (1960) included both forms under the species Utetheisa ornatrix. Wunderlin RP, Hansen BF. 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). are treated as generic only. 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). Need two plants to cross-pollinate. Therefore, it is more commonly seen than nocturnal species of moths by the public. “They affect their livers and their alkaloids even have been found to have DNA damaging effects.”. They lay clusters of eggs on rattlepod plants (Crotalaria ... the leaves of host plants. The female herself also gains additional protection from predators due to the additional alkaloids from the male spermatophores (González et al. Proceedings of the National Academy of Sciences USA 97: 1634-1639. 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. 538-542. 930348.00 – 8105 – Utetheisa ornatrix – Ornate Bella Moth – (Linnaeus, 1758) Photographs are the copyrighted property of each photographer listed. 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. Records that list just a plant genus as host (eg Rosa), records that cite one unidentified species (Rosa sp.) 2003. Callosamia promethea, commonly known as the promethea silkmoth, is a member of the family Saturniidae, which contains approximately 1,300 species. (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. 1981, Dussourd et al. Lipsiae, sumptibus Guilielmi Engelmann, 1894. 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. Among them is Crotalaria spectabilis, showy rattlebox, which particularly stands out with its 6- to 8 feet-tall plants and beautiful yellow flowers. Round, fleshy, orange to red berries appear in late summer. Gainesville, Florida. The Lepidoptera of New York and neighboring states. 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 … Ithaca, New York. Adult ornate bella moth, Utetheisa ornatrix (Linnaeus), on fruit of lanceleaf rattlebox, Crotalaria lanceolata E. Mey. Moths of Western North America. Since different plant species attract different butterflies, you need to choose the right host plants for the survival of caterpillars.
