Was going to get rid of some nettles earlier this week only to find one
clump swarming with caterpillars (Probably painted lady) several hundred and
all about 1/2 inch.
Late, but they may well miss the birds that so often have them with me
earlier in the year.
a few years ago I was going to spray nettles in the spring, only to find
they were all swarming with caterpillars, so I left them.
Within a week not 1 caterpillar left, watched Blue tits gathering them to
feed their chicks, so some wary nice blue tits but few butterflies.
