The hypericum rhopalid is a hairy, reddish-brown bug with membranous forewings, alternating dark and light bands along the sides of the abdomen, and a whitish, two-pointed tip to its scutellum.

Adults and nymphs feed mainly on Hypericum species through the warmer months, though the bug will also take a range of other low-growing plants.
