Anasa tristis of the family Coreidae is a major pest of squash and pumpkins, and is a vector of the cucurbit yellow vine disease bacterium.[1] These bugs can emit an unpleasant odor when disturbed.

This is the "squash bug" of North America, but properly it is known as orange-tipped leaf-footed bug,[2] since "squash bug" is a name applied to any common Coreidae species that include Cucurbita among their host plants. In Europe, for example, the dock bug (Coreus marginatus) is "the" squash bug.
