I seem to have lost the data for your Chetostoma curvinerve specimens! As I am near completing my paper for the Dipterists Digest can you send them again? The basic data are: date, site name, site grid and any comments on habitat etc. Thanks in anticipation.
We still don't know what the larval food plants of Chetostoma curvinerve is, but it is likely to be a berry-bearing plant of some kind. Do you also have anything like Cherry Laurel or Ivy in your garden?
I see on Flickr that you recorded Chetostoma curvinerve last year. As I am compiling a paper on the occurrence of this species in Britain I wounder if you would provide details.
