I have always had plenty of b'flies in my garden which has lots of nectar producing plants, but this 'summer' has provided very few. I saw a holly blue (the first) yesterday and this AM I saw the first peacock. I am assuming that this is due to the weather of recent months but I would ask the forum if this situation is countrywide.
Although there seem to be a few Blue Skipper and Meadow Brown butterflies on the Downs near where I live (Isle of Wight) I must admit I have not seen many others. Cinnabar moths are not particularly evident, judging by the small number of caterpillars I've seen, yet in other years there have been lots about. Not even much evidence of Cabbage White on my nasturtiums, which does indicate we have a problem. I was idly speculating last week whether to think about nurturing some caterpillars at home for overwintering and releasing next spring, but am reluctant to disturb the natural process too much. Haven't seen anything other that very common species which is a worry - or maybe a sign I need to get out more ;0)
