Crane Flies are flies, not big mosquitoes or daddy-long-leg spiders
They belong to the family Tipulidae, which interestingly has more species than any other fly family in Australia. This family belongs to the suborder Nematocera, which does include Mosquitoes, Midges and Sand Flies. However the Crane Fly is quite harmless, it neither bites, stings or sucks blood, in fact many do not eat at all, being only able to drink, consequently they are very short lived and mainly exist to establish the next generation.
With legs like these, they can't even run fast, particularly when some are easily mislaid.
Crane Fly from the family Tipulidae
Most Crane Flies have an aquatic larval stage and generally prefer moist shady environments, so they are far more common in the near east coastal areas from Tasmania to north Queensland. However we do have over thirty WA species from several genera, whereas in the east they have many times that number. Besides those that prefer aquatic environment, there are also some that breed in moist soils, compost and rotting vegetation. These larvae of these will feed on the decomposing vegetation and/or small invertebrates.
With such long legs, some positions are out of the question.
Unless you look closely, you would think that this fly has a large head and a long proboscis, but on closer inspection it is the thorax that is large and the proboscis looking part, the real head. Examination of the antennae, this species has unbranched tips, which taxonomically places it in the subfamily Tipulinae. Unfortunately I cannot id it to genus let alone species level, as these details are only published in specialist journals that I do not have access.
