Downlooker Snipe Fly (Rhagio scolopacea)


This fly gets its name from the habit of resting with its head down on tree trunks. It is usually in flight from May to August. This one was spotted on a stile close to a meadow near woodland in Darwen, Lancashire on 2nd June 2011. The female of the species, as shown above, can be distinguished from the male by the separation of the eyes; the eyes of the male are close together. It belongs to the family Rhagionidae. The larvae are predators on other insects and are often found living in rotting wood.

Gymnocheta viridis (a Tachinid Fly)


The images above were taken at Brockholes Wetland Reserve, Lancashire on 6th June 2011.
This beautiful fly is often found close to woodland. As an adult it feeds on nectar and pollen but its larvae are endoparasitoid on moth and butterfly caterpillars causing their host's eventual death. This fly belongs to the family Tachinidae all of which are endoparasitoids on other insects. At a glance it can be mistaken for a greenbottle but differs in that it is covered in bristles.

Sawfly (Tenthredo sp.)


This sawfly, Tenthredo sp. (probably T. mesomelas ) like other sawflies belongs to the order Hymenoptera which includes ants, bees, wasps and ichneumon flies. Sawflies are plant eating insects and the female lays her eggs inside the plant host. This is aided by the female having a saw-like structure on the ovipositor which is used to cut through the plant tissue. Both body shape and wing venation closely resemble ancestral forms found in fossil records that date back as far as the Triassic Period (200 million years ). The image above was taken in grassland at Brockhole Wetlands, Lancashire, 5/6/10.
