Angle Shades Moth - caterpillar

I've seen some strange things in my life but this is a good one. Yesterday I was feeding the rabbits and came across this Angle Shades caterpillar feeding on their cabbage.  A bit of research and it transpires that this caterpillar is quite active in the winter. You learn something new everyday.  Oh and they also they come in two different colours, green or in this case brown.
