Eastern Boxelder Bug

This bug is found primarily on boxelder trees, as well as maple and ash trees. The adults are about 12.5 mmm (0.49 in) long with a dark brown or black coloration, relieved by red wing veins and markings on the abdomen; nymphs are bright red. Boxelder bugs are redolent and will release a pungent and bad-tasting compound upon being disturbed to discourage predation; this allows them to form conspicuous aggregations without being preyed on. In the spring, the bugs leave their winter hibernation locations to feed and lay eggs on maple or ash trees; aggregations may be seen during this time and well into summer and early fall, depending on the temperature.
