Similar to an assassin bug but their bodies are slender, and the protonum is longer and slimmer.
They have well developed front legs similar to the raptorial legs of the praying mantis, which they also use to grasp their prey.
They are grey-to-light brown in colour and very fast moving.
The nymphs look like smaller, wingless versions of the adults. In other species some early instars mimic ants, making them difficult to distinguish from the nymphs of some pod sucking bugs.
Adult size: 8-10 mm
