No, he’s not one of the ninja turtles. It’s a caterpillar, eating on a lime leaf. :)
It will soon become a lime swallowtail butterfly. It has no tail unlike most swallowtail butterflies.
The caterpillar’s length was about four to five centimeter and it consumed a lot of lime leaves. The poop was rounded and black.
