Spotted next to my side gate yesterday:
Abraxas grossulariata (Magpie Moth) caterpillar
I took this photo of a Magpie Moth in 2009:
This is a Summer daytime flying moth. The caterpillars may be found feeding on Blackthorn and Hawthorn but can also cause widespread damage to the leaves of currant and gooseberry bushes.
