Abstract

The life cycles and larval feeding habits of Leucopis (Neoleucopis) pinicola Malloch and Chamaemyia polystigma Meigen were studied in northeastern Ohio. The larval stages of L. pinicola are predators of the pine bark aphid, Pineus strobi (Hartig) (Homoptera: Adelgidae). Probably there are only two generations a year, and overwintering occurs as mature larvae or pupae that are in diapause. Larvae of C. polystigma prey on the blue grass mealybug, Heterococcus nudus Green (Homoptera: Pseudococcidae), that infests perennial rye grass, Lolium perenne L. This species has three generations a year and overwinters as diapausing mature larvae and pupae.

The eggs, three larval instars, and puparia of both species are described and illustrated.
