Earlier this month our volunteer, Annabelle Hammond, found this awesome caterpillar whilst managing some of the willow.  It turned out to be a very rare species called the willow sawfly (Cimbex luteus).

Sawflies get their name from the female’s saw-like genitalia, which are used to cut or drill into a host plant so she can lays her eggs inside.

Although rare, none of the sawfly family have a conservation status in the UK.  This is because, they are regarded as a garden pest, as the larvae will feed on the plants they hatch within.  Willow sawfly larvae eat willow, as the name suggests.  Sawflies are related to wasps but don't sting.
