bella moth host plant

Posted on Dec 4, 2020 in Uncategorized

1. United States Department of Agriculture. 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. This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). “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. Adult and larva of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 1980, Jain et al. Robinson GS, Ackery PR, Kitching IJ, Beccaloni GW, Hernández LM. 2015. 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. Atlas of Florida Vascular Plants. McGuire Center for Lepidoptera & Biodiversity. Tietz, HM. Back to Species List. Eisner T, Eisner M. 1991. 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. Creating a list of host plants is the first step towards planning a butterfly garden. 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. 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. 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. However, cannibalism of pupae is minimized because larvae migrate off the host plant prior to pupation (Bogner & Eisner 1992). Not self-fruitful. An Index to the Described Life Histories, Early Stages and Hosts of the Macrolepidoptera of the Continental United States and Canada. Asters come in a close second on our list of native caterpillar food plants. Semiochemicals of. Covell CV. 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. It’s a vigorous slender evergreen vine that … Guimarães et al. Postcopulatory sexual selection in an arctiid moth (, Linnei C. 1758. Freshly emerged adult. 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. 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. Araujia hortorum. 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. Chemical defense against predation in an insect egg. 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). 1999), the jumping spider Phidippus audax (Hentz) (Eisner & Eisner 1991), and the orb weaving spiders .Trichonephila clavipes (Linnaeus) (Eisner & Eisner 1991, González et al. ), with flowers and fruit. During his experiments, spiders that caught bella moths in their webs and got a taste of the unpleasant alkaloids opted to cut the moths free, rather than finish the meal. A flower spike of lanceleaf rattlebox, Crotalaria lanceolata E. Mey, with carpenter ants feeding at extrafloral nectaries. Forbes WTM. 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. Vol. Photograph by Don Hall, Entomology and Nematology Department, University of Florida. This leads to another common name for the Bella moth: rattlebox moth. Powell JA, Opler PA. 2009. Eggs of the ornate bella moth, Utetheisa ornatrix (Linnaeus). 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. Also, the following six species of parasitoids have been reared from Utetheisa ornatrix pupae by Rossini et al. Adult ornate bella moth, Utetheisa ornatrix (Linnaeus). Special Publication Number 12. 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. Many other species of Crotalaria were introduced into the southeastern U.S. 55-65 years ago for soil improvement and forage. Today, the plant would control many Florida habitats if it weren’t for the tiny pinkish-red ornate bella moth keeping it at bay. Need two plants to cross-pollinate. 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). 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. 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. 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. Taming a wild plant may not sound too ominous, unless you are a tiny moth and the plant is 8 feet tall and poisonous. 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. Eisner’s lab experiments showed female bella moths are attracted to the same toxins in potential mates. In addition to sperm, males also transfer nutrients and HD to the female during mating via the spermatophore. Eggs are laid in clusters on the foliage. Vol. Back to Family Page. The pupae are encased in a brown and black sac covered in a light coat of silk. Pupae: The pupae are black with irregular orange-brown bands and are covered with a loose layer of silk (Figure 4). 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. Proceedings of the National Academy of Sciences USA 97: 1634-1639. Three species of Crotalaria have become established and are common in Florida. The moths sequester these poisonous chemicals and thus become poisonous to predators. Hare JF, Eisner T. 1993. But by late November each year, the plant had nearly disappeared. 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. For further information on Crotalaria species, see Isley (1990), Wunderlin and Hansen (2003), Wunderlin et al. 1983. 2011}). Interesting, this native moth develops more quickly on native crotalaria species. Natural Resources Conservation Service. A year later, he noticed the seasonal plant had dwindled more than 90 percent. 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. North American Moth Photographers Group (, Pease R. 1968. Part IV. Ferro VG, Guimarães PR, Trigo JR. 2006. Unlike most moths, which are nocturnal, the ornate bella moth is diurnal and flies readily when disturbed. The bella moth measures less than 2 inches, but it is vibrantly colored and active during the day and night. This is a fascinating discussion about the ecological consequences of invasive plant introductions. 1999). 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. Guide to the Vascular Plants of Florida. These plants produce pyrrolizidine alkaloids which are toxic to many species, but not the ornate bella moth. Figure 2. Fairchild’s writings suggest a variety of exotic rattlebox plants in the genus Crotalaria were introduced to South Florida about 100 years ago. This plant is a host of the ornate bella moth, Utetheisa ornatrix (Linnaeus). Florida Museum of Natural History photo by Andrei Sourakov. This allows it to be witnessed more frequently than other moths, which are mostly modestly colored and nocturnal.

A flower spike of lanceleaf rattlebox, Crotalaria lanceolata E. Mey, with carpenter ants feeding at extrafloral nectaries. Meanwhile, in Cross Creek, the moths start flying as early as March, laying eggs on the early sprouts of the native C. rotundifolia. 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. Pheromonal advertisement of a nuptial gift by a male moth, Dussourd DE, Ubik K, Harvis CA, Resch J, Meinwald J, Eisner T. 1988.
