A Wheel Bug (not a mis-pronunciation of "Real Bug") is easily identified by the spiny "wheel" on his back. Being 1 1/4 inches long and unusual in appearance, it can be quite intimidating. However it will make every attempt to avoid human contact. If handled, it may emanate a foul odor (it is in the same family as the stink bug) and try to bite.
The bite is more of a sting because it has a syringe-like beak (that reddish thing folded down under his face) that the bug inserts into its victims. It injects a venom which dissolves its prey's insides. In humans, this venom causes a burning sensation (similar to a bee or wasp sting) that lasts several minutes and leaves a wound that can take several weeks to months to heal.
Don't be too quick to shoo them out of the garden though. They are very beneficial because they eat soft bodied pests like caterpillars, aphids, moths, etc. I even read that they may eat Japanese Beetles!! Since we had an issue with Japanese Beetles this year, these bugs are more than welcome. In fact, my husband wants to look into how to encourage more.
They are a slow moving insect and generally won't land on you just to bite you. If one happens to land on you, gently brush it off. Once you know they have taken up residence, make sure you watch out for them when working in your garden.
