Abstract

Chrysocharis laricinellae (Ratz.) from Austria, Sweden, England, and Wisconsin, some of which were thought possibly different species, were crossed. Hybrid sex ratios in this arrhenotokous species were similar to parental types, indicating conspecificity. English and Wisconsin strains tended toward darker legs and female scapes.
