The adult squash bug is flat-backed, brownish black in color and measures
about 5/8 inch (16 mm) long.
Eggs are yellowish-brown to a very dark bronze-brown depending on
age. They are elliptical and about 1/16 inch (1.6 mm) long. Eggs are
laid in clusters on the undersides of leaves in the angle formed by
the veins. The clusters usually contain a few dozen eggs lying on
their sides arranged in rows in two directions meeting each other
at an acute angle. The eggs hatch in about one to two weeks.
The nymphs have a green abdomen with crimson head, thorax, antennae
and legs but soon darken to reddish brown. Older nymphs are grayish
white with black legs and antennae. The nymphs range in size from
3/16 to 1/2 inch (5 -13 mm) in length.
