Body is generally a dark brown, and varies around 2mm in length. The fore tarsi, and fore tibiae are light brown to yellowish brown (Stannard 1968), the mid and hind tibiae are brown, and the mid and hind tarsi are brown or yellowish brown (Nakahara 1985). Antennal segments 1 and 2 are dark brown, segments 3 to 6 are yellow and segments 7 and 8 are light brown. The forewings each have a light brown spot at the base, and are otherwise colourless. The head is longer than wide and transversely striate. The eyes are somewhat large, and ocelli are present. The postocular setae are mid-sized and somewhat dilated. Antennal segment 3 has 1 outer sense cone, segment 4 has 2 outer and 2 inner sense cones, and segment 8 is broadly joined to segment 7 and is not pedicellate (Stannard 1968). The major setae on the prothorax are dilated, though the anteromarginal setae are poorly developed (Nakahara 1985). The metanotum is so weakly sculptured that it is almost smooth, (Stannard 1968) and each fore tarsi has a small, subapical tooth on the inside of the fore tarsi (Nakahara 1985). The pelta is triangular and has longitudinal reticulations. Two pairs of wing-holding setae are present on each of abdominal segments 2 to 7. The fustis is mid-sized, and the tube is short (Stannard 1968).

Both sexes of this species are reported to be in Europe, though only females have been reported in the US and Canada (Nakahara 1985). In fall this species can be found in leaf rolls of Cornus Stolinifera (Heming Pers. Comm 2002).
