FLESH FLY & SAW FLY

Had a busy day at work today so glad to get home for my evening meal, did a couple of small jobs and then grabbed the camera and headed into the garden for half an hour. Not much to report as it was quite chilly and not much flying about, but did manage to catch a couple of species which are featured below.

The Flesh  Fly

This is one of several greyish species with large feet and red eyes, they cannot be reliably seperated without microscopic examination. The insects breed in carrion and are viviparous, with the females depositing small larvae instead of eggs.

The Saw Fly : Sirex Noctilio

There are two speces of this Saw Fly the other being Sirex Juvencus, these flies are active from May until October mainly around Pinewoods and plantations, where the larvae spend two or three years tunnelling into tree trunks. The larvae can survive in felled and sawn timber, and adults often emerge from Pallets and other timbers far from there original homes.
