Description
Wheel Bug (Arilus cristatus)

The Wheel Bug, in the Family Reduviidae, is one of the largest terrestrial true bugs in North America, being up to 1 1/2 inches, or 38 mm, in length; it is the only member of its genus. A characteristic identifying structure is the wheel-shaped pronotal armour. They are predators upon soft-bodied insects such as caterpillars, beetles, etc.

It has one of the most developed mouth parts among true bugs. Its beak arises from the anterior end of its long, tubular head and unfolds forward. The bug plunges its beak into its victim, holding them with its front legs. It then injects enzymes into the victim, paralyzing them and dissolving their insides, and proceeds to drain all of the victim's bodily fluids. The bite of a wheel bug is painful and may take months to heal (sometimes leaving a small scar), so caution is advised when handling them.

The wheel bug is also noted to be very vicious in the wild, and cannibalistic behaviors between them have been noted; for example, nymphs preying on nymphs and the female feeding on the male after mating is concluded.
