Aneugmenus fuerstenbergensis

Records are widely but sparsely distributed across much of Britain, and the species continues to be recorded in recent years throughout.

A black species with contrasting bright yellow legs. Males of Aneugmenus fuerstenbergensis are encountered as frequently as the females. The claws of this species are simple and lack an inner tooth (unlike all other Aneugmenus species). The abdomen is dulled by well-defined microsculpture (glossy at least on the first tergite in padi). In the male specimen seen, the pronotum is pale adjacent to the yellow tegulae.

Larvae unknown but believed to feed on ferns. They are green in colour and all larvae in the Aneugmenus genus have a v-notch in the first thoracic annulet behind the head.
