Extract

Conwentzia psociformis (Curt.) and Conwentzia pineticola End. differ as adults in only two characters, and since there are variable and intermediate forms occur, reliable determination is sometimes impossible. In the past, these two species have often been regarded as two forms of the same species.

The immature stages of C. pineticola are, however, very different from those of C. psociformis and show that the two are distinct species and can readily be separated on larval characters. The larval stages and egg of C. pineticola are described for the first time, and an account of its life history given.

The feeding habits of these two species are described, and mention is made of two other Coniopterygid species that occur in orchards.
