Yellow-Spotted Webworm Moth (Anageshna primordialis) lives in open savanna across North America. It feeds on grasses and leaves.
Fascinating facts about the Yellow-Spotted Webworm Moth
- The yellow-spotted webworm moth is the sole representative of its genus, making Anageshna a monotypic group within the Crambidae. The genus was erected by Eugene G. Munroe in 1956, establishing a unique taxonomic slot for this insect. Its single species, Anageshna primordialis, had already been described earlier by Harrison Gray Dyar Jr. in 1907, linking the two authorities across decades.
- Records show the yellow-spotted webworm moth occurring in more than twenty U.S. states, stretching from Maine in the far northeast down to Arizona in the southwest. Its distribution covers the eastern seaboard, the Midwest and the Gulf Coast, reflecting a broad ecological tolerance. Adults are active from August through November, a period that coincides with the late summer and early autumn months across its range.
- To date, researchers have not identified any plant that serves as a food source for the caterpillars of this moth. Its larval host relationships remain undocumented.
