During life history investigations on Xyela minor Norton (Hymenoptera, Xyelidae), larvae of two species of gelechiid moths were found feeding in the staminate cones of digger pine, Pinus sabiniana, along with the Xyela larvae. These moths are Exoteleia burkei Keifer (1931) and Chionodes sabinianae Powell (1959), the latter having been described from material collected during rhe course of our investigations. Exoteleia and Chionodes are not closely related genera within the family Gelechiidae, and the two species are related in the present study only by larval habitat.
