I've been having a slight problem with something munching on the leaves of my Meyer. Not widespread, half a dozen leaves or so. I've been treating with insecticidal soap and later on Sevin.
I caught this butterfly in my macro lens perched on an already chewed leaf and he just sat there. I watched him for a long time to see if he would actually eat the leaf. He never did.

Could the butterfly be what's munching on my leaves?

No, butterflies don't eat leaves!
But the caterpillar that produced the butterfly could well have done the damage some time ago before pupating.

Thanks for the reply. It seemed like a logical question. He was perched there and for all intents and purposes looked like he was there for a meal.
Glad to know he's not the culprit.

Those caterpillars I am aware of. They love my cilantro and they're responsible for some damage done to my sage this year. But unlike the cilantro and sage, I've never caught one on the Meyer.

The orange dog is the larva of the swallowtail butterfly. He will look like bird dropping and will run 2 red like horns out if disturbed and will give off a foul odor. If you like the butterflies leave him alone.

That bird poop camo has lost it's effectiveness! I was letting 3 or 4 go on my mandarin, but they did not make it--I think the birds have figured out the disguise.

If only a few leaves have cutout spots, it could be leaf cutting bees. They use the patches they cut out to line their nests.
