Squash bug (Anasa tristis) is a “true bug” with piercingsucking mouthparts (Order Hemiptera) in the leaffooted bug family (Coreidae). It is common throughout the U.S. and found from Canada to Central America. Adults (Fig. 1) emit a foul odor when disturbed and may be called “stink bugs”; however, true stink bugs are in a different true bug family.
