Adults appear in the spring and are short-lived (particularly males), the species spending almost all the year in the egg stage and larval development taking only 2 weeks. The reddish nymphs are covered in dark hairs and the two basal antennal segments are thickened. Males are attracted to UV light and may be found in moth traps.

Very common throughout Britain.

Common in Leicestershire and Rutland.
