This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

Tree from Stark and Stewart (1981).
Containing group: Plecoptera


Peltoperlidae is one of the smallest families of Plecoptera with approximately 50 species divided between the nearctic, palearctic, and oriental regions. The nymphs are very distinctive in being "roach-like" in appearance. They often occur in very shallow flowing water, such as seeps on rock faces, but are also represented in a wide variety of small streams and rivers. The adutls are recognizable in the field as having small heads when compared to other Systellognathan stoneflies such as perlids.


Synapomorphies for Peltoperlidae: 1, body stout, head prognathous, cockroach-like nymphal body form; 2, male cercal segments fused; 3, nymphal coxae with flap-like lobe.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
