Elephant mosquito

Toxorhynchites rutilus

''Toxorhynchites rutilus'', known generally as the elephant mosquito or treehole predatory mosquito, is a species of mosquito in the family Culicidae.
Elephant Mosquito (Toxorhynchites rutilus) On Boneset (Eupatorium sp.) at the edge of a dense mixed forest. 

As its name implies, this mosquito is gigantic! However, the adults are nectar feeders (not blood-feeders), so there is no need to fret! Also, their larvae feed on other mosquito species! If anything, I would say that this is a good mosquito to have around!
