Musgrave's Psednura - Psednura musgravei

Family Pyrgomorphidae

This page contains pictures and information about Musgrave's Psednura that we found in the Brisbane area, Queensland, Australia.
 
Female, body length 50mm
This Pyrgimorph can be found on grasses and sedges. Its stem-like and slender body make them camouflage well when they are hiding within grasses. They rest with head upwards, holding the grass stem with the front two pairs of tiny short legs.

When come closer to them, they try to hide by slowly move to the other side of the stem. When disturbed, they move up and down of the stem by the front two pairs of short legs.

Adults are wingless. They look very similar to those Matchsticks, but can be distinguished by the antenna and the back of their "neck".
