Nephrotoma australasiae Tiger Crane Fly
Crane flies (Tipulidae) are a family of insects resembling giant mosquitoes. Like the mosquito, they are in the order Diptera (flies). They have numerous other common names, many of them more or less regional, including daddy longlegs, mosquito hawks, mosquito eaters (or skeeter eaters), gallinippers, and jimmy spinners.
In appearance crane flies seem long and gangly, with very long legs, and a long slender abdomen. The wings are often held out when at rest, making the large halteres (balancers) easily visible (also visible on house flies).
