Male Agapema moth courtesy of Leroy Simon . The brown outer wing margins clearly distinguish homogena from other Agapema species. The single-brooded Agapema homogena moth flies from May through July in the U.S. and from May through September in Mexico. Agapema homogena moths emerge in the morning and mate after sunset with brief pairings, lasting less than two hours.
Males use well-developed, light coloured, quadripectinate antennae to locate the calling females.
Ova are deposited in large clusters on host plants. Gregarious larvae feed in large groups which become progressively smaller as caterpillars develop. Leroy Simon Photo Larvae leave the host plant to spin tightly woven cocoons in any kind of crevice they can find. Other Agapema species tend to weave cocoons on hostplants. Silk is at first light in colour but darkens with age.
