unusual group of insects are the Snake Flies, of which
there are just four UK species and about 20 living in
Europe. They are best looked for on the trunks of Oak and
Pine trees. All four of the UK species belong to the
Raphidiidae family and are terrestial insects. The larvae
live on or under loose bark and feed on other insects.
Females can be distinguished from males by the presence
of a long ovipositor. The adults emerge from early May
onwards and are thought to spend most of their time in
the tops of trees, accounting for the general scarcity of
sightings. Snake Flies seem poorly recorded insects, but
they are certainly some of the strangest and most
difficult to find.
