Fly ?

I think it is a Tipulidae...
Nice shot Les !

"Tipulidae is a family of large crane flies in the order Diptera.
There are more than 30 genera and 4,200 described species in Tipulidae, common and widespread throughout the world..."

It is one of the Ptychoptera craneflies, Les. Also known as Fold-winged Craneflies but the 'folding' of their wings makes full identification impossible.

Ptychoptera contaminata or lacustris or longicauda but it needs close examination of the wing veins to separate them.

All flies and only flies
are in the order Diptera, from the Greek words for two wings. Other insects, or at least most, have four wings, although in many species one pair has evolved into a sort of protective shell. Instead of a second pair, flies have little globular structures called halteres.

Geoff can correct me if any of this is incorrect.

Yes, flies in the order Diptera only have two functional wings. But there are many other fly families which have two pairs of wings (4 in total) but they are placed into different orders. For example the sawflies.

I'm not an entomologist, but I think this depends on whether one uses the scientific classification or common speech, and if the latter, which language one uses.

Sawflies are "flies" in common speech, but not in biology. They are closely related to wasps, bees, and ants, not to true flies, which is why they are in order hymenoptera rather than order diptera. Diptera subsumes flies and midges. For those interested in flies, an interesting if overwhelming site (there are a LOT of species of flies) is diptera.info.

Some languages hew more closely to the scientific classification in this particular case. If my vestigal German is correct, in that language, flies are Fliegen, and wasps are Wespen. House flies and robber flies are Stubenfliegen (room flies) and Raubfliegen, respectively. Sawflies are Blattwespen (leaf wasps).
