Description:

Long-legged and mainly nocturnal, these true bugs are stubborn pests that favor cucurbits. Both adults and nymphs suck sap from stems and leaf undersides. The 1/2 inch long, shield shaped adults are yellowish to black, while the smaller, tear-shaped nymphs are yellowish green with red heads. Squash bugs stink when crushed.

Life Cycle: After overwintering in debris, adults lay clusters of shiny, reddish brown eggs on leaf undersides and stems, Nymphs that hatch from a single egg cluster feed together. There is one generation a year.
