If only! Whilst it is sometimes as simple as that, there are plenty of exceptions (including virtually all micros). Anyone who thinks photographing moths must be easy all the time needs to have a go and share in the endless hours I've wasted over the years trying to get some inconsiderate six-legged bugger to comply. There are certain species which are almost always a pain in the arse, and White-marked is one of them - hence having to leave it yesterday and have another go this morning. At last it sat still for a few seconds so I got one shot without blurry wings.
Inconsiderate bugger - but a smart one
I was hoping to get a shot of the species-pair White-marked and Red Chestnut together - but I think that's going to be nigh on impossible.
