Criomorphus albomarginatus agg.


Length 2 to 4 mm. This is a difficult genus and the three UK species require reference to the genitalia for accurate discrimination. Because it is unlikely that the records we received will have been checked by genitalia we have decided to treat this species group as an aggregate. Both brachypterous and macropterous forms exist; in macropters, the veins have fine, pale hairs.

Identification difficulty

A variety of grassland habitats.

When to see it

April to August.

UK Status

True status is difficult to determine due to difficulty of identification, but the group appears to be widespread in Britain with Criomorphus albomarginatus being by far the most common.

VC55 Status

Status in Leicestershire and Rutland not known.
