Asciodema obsoleta (Hemiptera: Miridae): New Records for British Columbia and First U.S. Record of an Adventive Plant Bug of Scotch Broom (Cytisus scoparius; Fabaceae)

A. G. Wheeler, Jr.

Abstract


The European plant bug Asciodema obsoleta (Fieber) develops mainly on Scotch broom, Cytisus scoparius (L.) Link; it is one of several broom insects that apparently have been introduced to North America with shipments of nursery stock. This mirid first was reported in North America from British Columbia (Vancouver, Vancouver Island, Bowen Island) in 1966, but no additional records have been published. Based on specimens in BC museums and our recent field work, we extend the previously recorded BC distribution of A. obsoleta and provide the first U.S. record: Washington State (Point Roberts, Whatcom County).
