Zelus luridus

Species of true bug

Zelus luridus, also known as the pale green assassin bug, is a species of assassin bug native to North America. It is the most common Zelus species in the eastern United States. The size ranges from 12.5 to 18 millimetres long. On average, adult females are 16 millimetres (0.63 in) long, while males are 14 millimetres (0.55 in) long. Though the base color is pale green, markings on the back can range from dark brown or red to bright yellow. Nymphs are generally more solid green, wingless, and with narrower bodies than adults. The most reliable feature to distinguish this species from others is the pair of spines on the rear corners of the pronotum. These spines are long on the lighter colored individuals and shorter on ones that are darker. It can also be distinguished by dark bands on the distal ends of the femurs, but these can often be too light to be easily seen. The egg masses, which are laid from late June to August, are conical in shape with a flat top. They are laid on leaves in groups of twenty to fifty and held together with a sticky, brownish material. Their bite is extremely painful.
