Females deposit bottle-shaped eggs in the fall on twigs and other surfaces which overwinter.
Nymphs , with red and black patterns, hatch in the spring. Older nymphs resemble adults but lack fully-developed wings. One generation is produced annually. Wheel bug nymphs and adults are predaceous on a wide range of insects including honey bees and caterpillars. However, they are rarely numerous, and therefore have minimal impact on prey insect populations in agricultural crops.
