Allotments 4 All

  Hi all,
   for the last two months or so, something has been eating my brassicas. The soft parts of the leaves are going  leaving a 'leaf skeleton'. I have surrounded them with slug pellets, but no dead slugs evident, I have looked carefully no sign of caterpillars or anything else on the damaged leaves.
   The mystery deepens, when I walk my dog in the morning across a field that had rape in it  in the Summer and now has some  sort of 'beet' growing, right across thy field  all the little plants are showing the same damage I am experiencing! Just wondered if anyone had any ideas what the culprit could be?

Could be a cabbage looper which is a small green catapiller have a closer look bothe under and on top of the leaves

Slugs are doing that this year too...
