I don't think these pics are good enough for the gallery, but I thought it was worth posting them to show what another species of Chymomyza looks like. (We've had quite a few of Chymomyza amoena, with its banded wings.) I found both females and males (these are the male) on a Salix tree which had been stripped of some bark. This is a typical habitat for the species. The locality was beside a lowland river, near Norwich, England. 2 Sept. 2007 Tony Irwin attached the following image:  [31.12Kb] Tony ---------- Tony Irwin |

The larvae, which are always found under bark, probably feed on micro-organisms (yeast and other fungi) that invade damaged trees. Chymomyza amoena is unlike the other species - its larvae feed on micro-organisms that grow on the frass produced by caterpillars that bore into nuts, etc. Tony ---------- Tony Irwin |
