Genera

see text

The family Phylliidae (often misspelled Phyllidae) contains the

extant true leaf insects or walking leaves, which include some of the most remarkably camouflaged leaf mimics (mimesis) in the entire animal kingdom. They occur from South Asia through Southeast Asia to Australia. Earlier sources treat Phylliidae as a much larger taxon, containing genera in what are presently considered to be several different families.[1]

Characteristics

Leaf insects are well camouflaged, taking on the appearance of leaves. They do this so accurately that predators often are not able to distinguish them from real leaves. In some species, the edge of the leaf insect's body has the appearance of bite marks. To further confuse predators, when the leaf insect walks, it rocks back and forth, mimicking a real leaf being blown by the wind.[2]

Tribes, genera and species

The subfamily Phylliinae has been divided into two tribes since 2003. This classification is not confirmed by more recent molecular genetics investigations. In addition to the fossil genus Eophyllium, the subfamily distinguishes thirteen recent genera, eight of which have been described since 2017.[5] Within the genus Phyllium, the subgenus Pulchriphyllium, set up by Achille Griffini in 1898, has been distinguished from Phyllium since 1898.[6][7] With Comptaphyllium and Walaphyllium two more subgenera became in 2019 and 2020.[8][9] As of 2021, all three subgenera are considered separate genera.[10]

Since 2021, in addition to morphological, molecular genetic studies have also increasingly been included in clarification of the phylogeny of Phylliidae. Their results show the general relationship between the genera, but when comparing female and male representatives, they do not yet provide a clear phylogenetic picture of the recent genera.[11]

Captivity

Several species have gained in popularity as pets including Cryptophyllium celebicum, Cryptophyllium westwoodii, Phyllium jacobsoni, Phyllium ericoriai, Phyllium siccifolium, Phyllium letiranti, Phyllium monteithi, Phyllium philippinicum , Phyllium rubrum, Phyllium tobeloense, Pulchriphyllium bioculatum and Pulchriphyllium giganteum .

Extinct species

A 47-million-year-old fossil of Eophyllium messelensis, a prehistoric ancestor of Phylliidae, displays many of the same characteristics of modern leaf insects, indicating that this family has changed little over time.[13]
