Spilomelinae compreende mais de 5.200 espécies descritas em todo o mundo. Várias são conhecidas por seu impacto econômico nas lavouras, ocorrendo altas populações plantas hospedeiras, com diferentes graus especificidade ao hospedeiro. O objetivo foi registrar lagartas Syngamia florella (Stoll in Cramer & Stoll) (Lepidoptera: Crambidae: Spilomelinae) alimentando-se folhas Ipomea batatas (L.) Lam...
