The species is found in Europe from Ireland in the West and including the northern edge of the Mediterranean and the East across the Palearctic to Central Asia, Korea and Japan.

Adults are 2.0-3.1 mm long and are a golden brown color, and have a pale-orange head and are therefore easily identifiable.

They are similar to Bryocoris pteridis from which they can be distinguished by the first segment of the antenna, which is shorter than the head is wide.

The males are strong fliers and swarm during the mating season, when they are found also on other plants.

The females lay green eggs from May until early June on the host plants, where they are indistinguishable from the similarly colored spores.
