Here is a very young nymph of the leaf-mimic katydid Phoebolampta caeruleotergum. This species was discovered on St. Martin in 2006. It is possible that it also lives on other nearby islands, but I have not yet seen it documented anywhere except St. Martin. The adult is primarily green, with angular wings that make it look very much like a leaf. Most katydids are nocturnal, so their leaf-like appearance helps them rest undetected on plants during the day.
