Locust Blow Fly

Stomorhina lunata


Over all length 8 - 10mm. Looks superficially like a hoverfly. The male has orange on segments three and four, in the female they are greyer. The face protrudes to a point.


Adults are normally seen feeding from flowers, often umbellifers. The larvae predate the eggs of the Locust, so any adults seen in Britain will be migrants.

Status and distribution

Rare migrant to the south and east of England, although there is one record from the north of Scotland. First record for the reserve was in 2014, but by 2020 there were several records.
