Anoplophora glabripennis is a large wood-boring cerambycid beetle that has recently invaded North America and Europe from Asia. We discovered the common house spider, Achaearanea tepidariorum, in large cages housing A. glabripennis on trees and confirmed the ability of A. tepidariorum to prey upon adult A. glabripennis by placing the two species together within smaller containers where they could be more easily observed. Adult A. glabripennis, up to 600% of the spiders’ body length, exceed the maximum relative size of prey previously reported for A. tepidariorum or for solitary webbuilding spiders in general.
