Euura stenogaster (Förster, 1854)

Euura stenogaster

Specimens recorded as this species, or under the synonym Amauronematus fallax, may contain other overlooked species in Britain. The presence of this species in Britain and Ireland is uncertain. Several specimens labelled as Amauronematus stenogaster or Amauronematus fallax were examined prior to 2010 by Liston et al and all were found to be either Amauronematus mimus, or another unknown species resembling mimus.

Larvae feed on creeping willow.
