Adult coccinellid abundance was monitored in agricultural areas of the Tanana and Matanuska—Susitna River Valleys of Alaska during 2004 and 2005. Thirteen species were collected in association with Alaskan agricultural crops. Of the species collected, Hippodamia quinquesignata quinquesignata (Kirby), Coccinella transversoguttata richardsoni Brown, and Hippodamia tredecimpunctata tibialis (Say) were by far the most abundant species, making up 51, 18, and 12%, respectively, of the individuals collected. Two new species, Coccinella septempunctata L. and Hippodamia convergens Guerin, were recorded for the first time in Alaska.
