Keys for the British species of Asilidae

These are the robber flies which use their elongated legs to catch other insects on the wing. 16 genera are found in the British Isles, from four subfamilies - a total of 29 species. The key should allow identification of our species.

There are online keys to the European species here: http://www.robberflies.info/keyger/htmle/key.html

For more information I would recommend buying a copy of British Soldierflies and their Allies by Stubbs and Drake, available here http://www.benhs.org.uk/publications/british-soldierflies-and-their-allies-second-edition/
