Species text
Campsicnemus magius is a small dolichopodid fly in which the front legs of the male are strongly ornamented with processes and bristles which give the appearance of additional legs. It is given Near Threatened status in a recently published national status review (Falk & Crossley, 2005) and is also a new UKBAP species. Most records are from the Thames Estuary. The fly occurs on bare mud in coastal levels and upper saltmarsh where there is an intermediate level of salinity and does not normally occur on the tidal parts of a saltmarsh. The larval biology is unknown, but it is probably a semi-aquatic predator in mud. Adults are found skimming across areas of gently shelving bare mud. References
