The Latin species name hortulanus means garden warden.[3] Distribution and habitatThis species is present in most of Europe,[4] in NW Africa, the Caucasus, Asia Minor, Iran, Siberia, Central Asia and India.[5] These beetles mainly inhabit meadows and hedge rows.[6] DescriptionCionus hortulanus can reach a length of {{convert|3|-|4.6|mm}}.[6] These tiny beetles have a short, oblong and convex body, a conical thorax and a long thin rostrum. Thorax and elytra are covered with grey scales. The basic body color is grey-brown, with one large velvety black spot in the middle of the elytra and a smaller one at the apex. The elytra bears four raised lines with a series of black markings. The antennae are reddish.[7] BiologyAdults of these beetles can be found from June to September.[6] They feed on leaves of Buddleja and Verbascum species, while larvae feed on Water Figwort (Scrophularia auriculata), Common Figwort (Scrophularia nodosa)[6] and Great Mullein (Verbascum thapsus).[8][9] Females lay eggs on leaves of the host plants.
