This moth- Geina periscelidactylus which is not the first image that comes to mind when you think of a moth landed on a milkweed leaf as a gentle rain was falling. Every day there is something different on our milkweeds but so far nary a Monarch larva. We have been visited by the butterfly and I did find an egg under one leaf but that apparently was eaten by someone and no caterpillars yet.
I think it is interesting that its species name sounds like pterodactyl. It does seem a bit prehistoric.
In case you are wondering why only part of the leaf is sharp, the leaf was curled and the idea when photographing a moth or other subject is to get as parallel to the subject as possible so that take priority and the leaf second place. This was shot at f/16 so even with that increase depth of field the leaf still fell out.
