Cantharis nigra (Degeer, 1774)

Female
Widespread across England, Wales and southern Scotland. Common and associated with moist habitats e.g. Marshes, wet meadows and shaded waterside vegetation. Adults from mid May until early August, late in the season they become adventitious and may be found from any suitable habitat. The specie's inclusion on our list is based on several specimens from Sarrat Bottom during June (2003 and 2006), although we have yet to find it nearer Watford we have no doubt it will turn up as there is much suitable habitat locally.

5.5-7.5mm. Elytra covering abdomen and wings, black with fine pale pubesence giving the insect a shiny appearance to the naked eye. Scutellum black (cf C.thoracica (Olivier)). Pronotum appearing impunctate (X10), front margin evenly rounded and covering base of head. Margins explanate, widest at front angles and without basal fovea, varies from red to completely dark. Head black, yellow in front of eyes. Antennae black with the basal segments orange. Terminal segment of maxillary palpi flat and broad, dark. Legs orange, tibiae sometimes darker, tarsi dark or with basal segment orange. Third segment of mid and hind tarsi bilobed, anterior claw on each leg toothed at base.
