The “meat” of the insect can then be sucked up through the wheel bug’s strawlike beak.

Todd (1937) reported the wheel bug under natural conditions as being very aggressive in the nymphal and adult stages of development. This aggressiveness was not so pronounced in individuals under observation in cages. He noted that specimens collected in the field became accustomed to being handled in a very short time. The wheel bug has also been reported as cannibalistic, usually based on caged specimens. Nymphs have preyed upon nymphs, and Barber (1920) reported females killing and feeding upon the males soon after copulation was complete.

Froeschner (1944) counted 76 wheel bugs at one time at lights in front of a store in southern Missouri.

Description
Origin and Distribution
- Wheel bugs are native to North America, occurring from the Northeast to the Southwest regions of the United States.
Habitat & Hosts
- All life stages are predatory and feed on other arthropods such as caterpillars, moths, and other soft-bodied insects. Wheel bugs use their enlarged forelegs to grasp prey. Upon capture of their prey, the wheel bug holds its prey in place while it pierces the prey and ingest the body fluid with its stout beak.

- As is the case with all insects that belong to the order Hemiptera, wheel bugs follow an incomplete life cycle: eggs, nymphs, and adults. There are five nymph stages for this insect. The wheel bug lays its cylindrical, brown eggs in groups. Eggs overwinter and hatch in the spring and continue developing until reaching the adult stage in summer or fall. Small, red and black wheel bugs em…
