I coaxed him onto my windowsill and when he was there put a slice of apple there.
He (or she?) is actually eating the apple and you can actually see some of it in the mandibles.
Later as a reward for being a model I put a plastic cup over him and slid a piece of card under it.
Then I was able to open the window and he flew away.
I used the Canon 100mm macro fitted with 3 Kenko extension tubes on my Canon 1Ds MkII
