Infestations of large numbers of leaf foot bugs? See Leptoglossus clypealis web page.

My interest in the Coreidae has focused on the Western Conifer Seed Bug, Leptoglossus occidentalis Heidemann. This conifer pest has spread from western North America across to eastern North America, and has recently turned up in Italy.
