Abstract

High altitude occurrence and westward expansion of the seven-spotted lady beetle, Coccinella septempunctata (Coleoptera: Coccinellidae), in the Rocky Mountains.

Abstract

In a survey in 1990, Coccinella septempunctata (which had been introduced into North America as a biological control agent) was recorded at several sites in the Rocky Mountains at altitudes of up to 3475 m. Individuals were collected from Compositae and other flowering plants, under rocks in alpine tundra, on a snow field and in the air. Records for Washington and Montana are claimed to be the most westerly observations of the predator in the USA.
