I thought this fly looked very striking with its patterned wing markings, but I assumed it was a crane fly. Not so. These are related to the crane flies (Tipulidae) but can be distinguished by the way they hold their wings at rest. Crane flies usually hold their wings outstretched, but limonia flies fold theirs along the back of their body. Both only have fore wings; the hind wings are reduced to little knobbles. Limonia flies also tend to have aquatic or semi-aquatic larvae, whereas Tipulidae have land-based larvae. I think this is a Limonia nubedulosa because of the wing pattern, stripy legs, and brown head.
