I have been a fan of the ambush bug for a long time. Every time I take a walk in the summer, I am careful to inspect Queen Anne's Lace (a common white flowering weed in the Midwest, USA) for the ambush bug. They wait for unsuspecting flies, moths and other insects to land... then grab the prey with pincer-like forearms before injecting their poisonous probiscious into the poor prey.
With the exception of one photo, these ambush bugs were photographed at Prairie Oaks Park in Central Ohio. The exception was found in my backyard.
