I grow Brassicas which you may know as a fancy name for cabbages, cauliflowers, turnips, radishes etc. Enter, the Cabbage White Butterfly which probably has a Latin name but who cares? These beasties used to lay neat yellow clumps of eggs on the leaves of my crops that hatched out into caterpillars and decimated the foliage.
So I got a system. Once or twice a week, I'd check the kitchen garden for said neat yellow clumps of eggs and squash them. Result! No caterpillars. Woot!
Until this year when Charlie upped the ante. I found a load of fully-grown caterpillars munching away at the kohlrabi leaves. On the Sea Kale too. No eggs anywhere!
I'm still trying to work out how he's done it. Maybe there are eggs but they're so small or well camouflaged that I haven't spotted them. Or maybe the eggs are just as big as they ever were but were laid on some other plant and the caterpillars marched across the lawn?
Answers, as they say, on a postcard.
