Aradus depressus
Family: Aradidae

Unlike Aneurus species, the wing membrane in Aradus flatbugs does not extend below the apex of the scutellum. A. depressus is distinguished by the pale shoulders, and the 2nd and 3rd antennal segments are similar in length.

This is the most common UK flatbug, found under the bark of various trees
which are infected by fungi, particularly native deciduous species.

Although widely distributed across England and parts of Wales, it is not often recorded. It appears not to have a strict reproductive seasonality, although nymphs are more common in the summer.
