Dasysyrphus pauxillus (Williston, 1887)

Biology & ecology:

Members of the genus Dasysyrphus are aphidophagous but, as yet, the larva of D. pauxillus is unknown. Adults appear to be associated with conifer plantations.

Distribution:

It has already been recorded from two sites in the Brecks of East Anglia. This was a North American species that has been spreading west across Europe and its arrival in the UK had been expected.

Status & conservation:

This species was added to the British list on the basis of two specimens taken in 2010 (Rabbarts, 2010) and is probably a recent arrival.
