There are four main bands located at the base, the middle, a subapical band before the apex and an apical band along the wing tip which joins the subapical band at the costa. Two other accessory bands may be found, a posterior apical band between the apical band and the subapical band, or a short costal band starting from the costa between the middle band and the subapical band. The presence and shape of these band can be characteristic for the species. The body is usually between 3 and 5 mm long, the tarsi of many species are yellow, as are part of the tibiae.
