Heterocampa

Doubleday, 1841

prominent moths

Heterocampa is a of in the containing approximately 18 described . Species occur in North, Central, and South America. The genus has undergone taxonomic revision; research published in 2021 resulted in some species being transferred to the genera Cecrita, Macrurocampa, and Rifargia. Several species are forest defoliators, with Heterocampa guttivitta (saddled prominent) and H. manteo (variable oakleaf ) being among the better studied due to their economic and ecological significance.

with , larval, and pupal stages. Heterocampa guttivitta has at least five larval . Heterocampa manteo has multiple larval instars with documented morphological criteria for distinguishing instars.

Ecological Role

Forest defoliators; serve as for diverse including (Telenomus coelodasidis, Trichogramma minutum), larval parasites (Phobocampe pallida, Eulophus anomocerus, Diradops bethunei), and pupal parasites (Cratichneumon sublatus, Patelloa , multiple ). are influenced by parasitoid pressure.

Human Relevance

Taxonomic History

A 2021 taxonomic revision reassigned several from Heterocampa to the Cecrita, Macrurocampa, and Rifargia. This reflects ongoing research into phylogenetic relationships within the .

Parasitoid Research Significance

Heterocampa , particularly H. guttivitta and H. manteo, have been extensively studied as model systems for understanding - relationships and in forest . Research has documented rates varying with host , with pupal parasitism by Cratichneumon sublatus increasing from 1-17% during to 32-57% following host collapse.
