Huebneria affinis at Rye Harbour

On the 20th June 2007 I collected several parasitic flies from shingle to the west of Ternery Pool. Most of these were readily identified, but one left me stumped. I subsequently handed it on to Chris Raper, the national recorder for this group, and yesterday he came back with an answer. It is Huebneria affinis, an extremely rare fly in Britain (RDB1 – Endangered) with only two records, from Folkestone in 1866 and Deal in 1921. Larvae of this species are parasitoids of Arctiid caterpillars (‘woolly bears’ such as Garden Tiger and Cream-spot Tiger), so Rye Harbour is the ideal place for them.

RSPB Dungeness Nature Reserve

Today two glossy ibis have been seen on the lakes near Boulderwall farm and a bittern flying at Hookers pits. Yesterday, as well as glossy ibis and bittern, the great white egret was at Denge Marsh and a raven was flying across the reserve. On the 24th we also had two penduline tits at the ARC site and a goosander on Burrowes pit.
