squash bug

 or leaf-footed bug

Any of more than 2,000 widely distributed insect species (family Coreidae), including many important plant pests. Most species are dull-coloured and more than 0.4 in. (10 mm) long. Many have enlarged, flattened extensions on the legs. The North American squash bug (Anasa tristis) is an important pest of squash, melon, and pumpkin (plants in the gourd family). It is basically yellow but is covered with black pits that make it look black. The larvae feed underground, and the piercing and sucking mouthparts of the adults enable them to attack the parts of plants that insecticides rarely penetrate.
