Abstract

A total of 5183 adult aquatic insects, representing 3 orders, 7 families, and 16 genera, and 1447 adult terrestrial insects representing 8 orders and 21 families, were light trapped at Lake Murray Reservoir, San Diego County, California, from 17 April–25 November 2019. Diptera was the most abundant taxon for all sampled individuals. A single species of mayfly, Caenis amica Hagen, 1861, was collected. Five aquatic Diptera and three Trichoptera species are new distribution records for San Diego County. A second state distribution record for the micro-caddisfly, Oxyethira arizona Ross, 1948, is also reported. New observations of adult swarming behavior of the caddisfly, Oecetis inconspicua (Walker, 1852), are reported.
