The parasitic Five-Banded Tiphiid Wasp is good news for flowers, but bad news for beetles.
This medium-sized wasp is highly beneficial because they prey on a variety of beetles that destroy trees and flowers. The female wasp lays an egg on May Beetle larvae buried in the ground. The wasp larva hatches and immediately invades the beetle where it slowly eats it from the inside out, eventually killing it. The wasp larvae then mature into adults in early summer.
Unfortunately, this wasp is also a victim of parasitism by Velvet Ants and may find its own larvae the acting as the meal of that wasp (Velvet Ants are actually wasps in disguise).
Males have a pseudo-stinger at the tip of their abdomen, while females have the real thing. Adults drink nectar from flowers. This species can be found in gardens, meadows, fields or on lawns.
