Utetheisa pulchella crimson speckled moth
Description
Palpi porrect, extending beyond the frons. Antennae ciliated. Fore wings long and narrow, where the outer margin short and somewhat erect. Vein 3 from before angle of cell. Veins 4 and 5 from angle, vein 6 from upper angle and vein 7 to 10 from a short areole. Hind wing with vein 5 from above angle of cell. Vein 6 and 7 from upper angle and vein 8 from middle of cell.
Caterpillars of many Utetheisa species feed on Crotalaria (rattlebox), and hence the genus as a whole is often called rattlebox moths. The adults usually have bright aposematic coloration and contain toxic pyrrolizidine alkaloids, which are used as a chemical defense and are also incorporated into the sex pheromones of the males.
Taxonomy
