Essex Red Data List comment
Restricted to dune/heath habitat. Recorded from dune-like PFA lagoon habitat at Barking Levels (now destroyed) and Chafford Hundred (area now built on).
This small stiletto fly is widely distributed on coastal dunes on the east coast. It also occurs inland although this is rather unusual, notable in the Breck district of East Anglia and on some heaths and commons (Stubbs & Drake 2001). In Essex there are very few records including Barking PFA lagoons (now destroyed) and Chafford Hundred (area probably now destroyed). References
