Aradus

Aradus is a genus of true bugs in the family Aradidae, the flat bugs. It is distributed worldwide, mainly in the Holarctic. There are around 200 or more species in the genus.

Most Aradus feed on fungi, often in dead trees. Some species are pyrophilous, associating with burned habitat such as forests after wildfires. They feed on the particular fungi that grow on burnt wood. Examples include A. laeviusculus, which eats fungi growing on burned conifers, and A. gracilis, which occurs in large numbers on burned South Florida slash pine (Pinus elliottii var. densa).
