For the uninitiated, a crane fly is best described as a giant mosquito. I have had some whose leg span is considerably bigger than my open hand. They are flies; members of order Diptera (Di - meaning two; Ptera - wings). You can clearly see this fly has the required two wings (unlike most of other insects) and a pair of drumstick-like halteres which are what remains of the hind wings.
