Phylliinae

Mating pair of Phyllium siccifolium, from Phasmids in Cyberspace.
Belongs within: Phasmatodea.

The Phylliinae include the leaf insects, characterised by having the abdominal terga and sterna dilated to mimic leaves. Living Phylliinae (excluding the plesiomorphic fossil Eophyllium messelensis) also have the tergal thorn pads reduced or absent, the fore femora straight, and the cerci dorsoventrally flattened (Wedmann et al. 2007).
