The Wheel Bug, or Assassin Bug as some call it, is a vicious predator of insects. And I do mean vicious. This bug attacks with intent to kill! It will defend it's meal with gusto. And it will inflict a painful bite to critters larger than humans when disturbed; bites which can take months to heal. It is a bug to be respected! But don't let me scare you, this bug is more good than bad in that it is a predator of many of the insects we call pests. Common in eastern North America, and desired.
