The Oleander Aphid and the Monarch Egg
You never know about those photo-bombers. You can't trust 'em. So here I was, trying to photograph a tiny egg that a monarch butterfly had just deposited on our milkweed. I held it up for a better look. And then, the photo-bomber! An oleander aphid, Aphis nerii, appeared...
