(Phyllium bioculatum)
The Gray's leaf insect, (Phyllium (Pulchriphyllium) bioculatum), is a leaf insect of the family Phylliidae native to west Malaysia. It was first described by George Robert Gray in 1832, which was his first phasmid he discovered. Leaf insects have extremely flattened, irregularly shaped bodies, wings, and legs. They are usually about 5–10 cm long (2–4 in long). They are called leaf insects because their large, leathery forewings have veins that look similar to the veins on the particular type of leaves they inhabit. Its Polish name is liściec dwuoki, which comes from the two dots located on the abdomen just in this species, as does the scientific name (bioculatum meaning "two-eyed").
