Genus Paracharactus

Paracharactus

A small genus of six species spread across the holarctic region. In Britain the genus is represented by a single species and is absent from Ireland.

The genus Paracharactus is characterised within the Blennocampinae by the following features. The malar gap is about the width of an front ocellus. The upper half of the outer orbits has a sulcus. The tarsal claws lack a basal lobe and only have a small, sometimes obsolete, inner tooth. The wings are only weakly infuscated. It should be noted that there is disagreement as to the precise characteristics that define the genus as the nearctic species are considerably more variable than the palaearctic species.

Larvae feed on Ranunculaceae.
