Lizard Feeding by Leptoconops (Brachyconops) califomiensis (Diptera: Ceratopogonidae) on Desert Sand Dunes

Abstract

Adult females of Leptoconops (Brachyconops) californiensis Wirth & Atchley and 1 female of Leptoconops (Holoconops) sp. near knowltoni were collected from 5 species of lizards in desert sand dune habitats in San Bernardino and Riverside counties, California, and northern Sonora, Mexico. Feeding by L. califomiensis was observed on the dorsum (usually the heads) of the lizards, with up to 6 L. califomiensis on a host at 1 time. The L. sp. near knowltoni appeared to be trying to feed but did not contain blood. Midges fed during calm, warm daylight periods from March through October. Reptile feeding by Ceratopogonidae is reviewed.
