Trapezonotus dispar Family: Lygaeidae Trapezonotus species are medium sized ground bugs which are rather oval in shape. The sides of the pronotum are regularly rounded and thinned at the edges to produce narrow keels.   This species was previously considered conspecific with T. desertus and T. arenarius, and the three species are very difficult to separate, ideally requiring examination of the male parameres. In T. dispar the blade of the paramere is very strongly angled (see right). This species is also generally slightly larger and the hind tibiae and sometimes the mid tibiae are usually partly pale or red-brown. Adults are frequently macropterous. Widespread in southern England and more strongly associated with wooded habitats than other species in the genus. Adult: All year Length males: 4.6-5.2 mm, females: 4.6-6 mm
