Crane fly

The adult crane fly has a slender body and stilt-like legs that are deciduous, easily coming off the body. The wingspan is generally about 1 to 6.5 centimeters. The antennae have up to 39 segments. It is also characterized by a V-shaped suture on the back of the thorax and by its wing venation. The rostrum is long; in some species it is as long as the head and thorax together. - from Wikipedia
