Took myself off on a mini tour of a selected few South Yorkshire reserves a few weeks back, including Brockadale and Blacka Moor (nr Sheffield). The most noticeable thing for me recently has been the number of butterflies on the wing lately. I suspect and hope it's been a good year for them after last year's wash out and by all accounts (mainly from the keen lepidopterists from Askham Bog) this does seem to have been the case. I hope you've seen plenty in your garden and not just the common white variety!
Here's a nice Marbled White for starters.
That was one of several I saw at Brockadale nature reserve nr Pontefract and an absolute haven for butterflies at the moment.
Same location and not really butterflies there were hundreds of these Burnett Moths in the fields around the reserve.
