Boosting your butterfly photos

It is Green Hairstreak season. I’d heard that this tiny, shimmering green butterfly had been spotted on Devil’s Dyke in Cambridgeshire in mid-April, so I headed out on foot to a local woodland patch that very day where the butterfly had been seen a couple of years ago. I was in luck! One specimen showing briefly. Unfortunately, I didn’t get a photograph on that visit. Next bright, sunshiny day headed out with Mrs Sciencebase to take another look. There were none on the expected patch, but we kept at it and rounded a corner where there was a Dogwood thicket and various other bushes with a crowd of Green Longhorn moth! So I got a couple of snaps of those. Green Hairstreak, Callophrys rubi Mrs Sciencebase spotted the first Green Hairstreak landing. And so with a little bit of patience I managed to get a few overexposed snaps. Using a new second-hand lens (Canon EF 75-300mm lens, 1:4.5-5.6 L IS USM) on my Canon 7Dii), I’ve not quite got used to just how much light it lets in compared to the Sigma 150-600mm I’ve been using since January 2017).
