Sawfly (or something simular) eating cabbage

[cambourne7]

Hi Guys,

The weekend i have noticed that my spring cabbage look like lace, and there are what looks like sawfly on them muching away.

I have sprayed with deris but can anyone tell me what time of year these should be attacking in normaly?

I knew i should have covered in netting but just though it was 2 late in the season (stupid me)

If they are green they are small cabbage white caterpillars. I've just been squashing them today! came home with green fingers. They show up well on my red cabbages. They do quite a bit of damage and produce lacy leaves.

Cabbage moth Caterpillars have a pattern, they can be green or brown. i posted a picture of one (not my picture though, one from the web)  last year that I found after a big hunt to find out what the caterpillar was hiding on my plot in late autumn. I can't find it again and I don't know where I posted it now.
