I've seen a lot of these shadow boxes with leps, but never one with a map as a background. This really adds a touch of class to the item! Adam's suggestion adds scientific accuracy to it, but as a beetle guy, I would never have caught that, and I suspect if you were producing these to sell, the average non-entomologist buyer wouldn't notice if they had been African species! But scientific accuracy is always better - even if it may go unnoticed...
Why is the Graphium weiskei on the Philippines? Perhaps you weren't intending to associate the butterflies with the places on the map.
Yes, you are right! I'm just putting them in order of size, though every butterfly in the picture should fit in at least somewhere on the map. I'm not selling these, I'm just making them for fun. I have a couple of more maps planned.
I did think about sticking some weevils on the map!
