Where's Wally?

I just had a bit of time before starting work to do some housework and finally got round to checking the spring cabbage seedings on the patio.  Something was making them holey.  Sure enough each one (on average) had 2-3 little green cabbage white caterpillars.  Very good camouflage especially on the stems so I may not have picked them all off but most of them are now on the patio for the birds.  Fingers crossed the little plants will recover nicely to be planted out in the next couple of weeks.  The caterpillars seemed to have stuck to the outer leaves although a couple of the bigger ones were clearly en route to the heart for a nibble.  

Hopefully, more digging at lunchtime today...
