The DBS patch still going strong
Re-visited the Devils-bit scabious patch again on Tuesday after work, with hoverfly numbers still high. Saw all the species I saw on Saturday plus further species in Chrysotoxum arcuatum, Eristalis rupium and Helophilus trivittatus. Sericomyia silentis numbers reached double figures also. A single very late Hogweed plant also produced a very late Cheilosia illustrata. Also present were the conopid flies Physocephala rufipes and Sicus ferrugineous.
