At least Lonchaeidae is correct

Hi Kurt adult Lonchaeidae are notoriously diffficult to ID from photos as most of the key characters are difficult to see - what I can say is that it is a female Lonchaea spp. - the rather obscurelly orange basal tarsomeres may suggest L. obscuritarsis or L. albitarsis but thats just a bit of a guess .........

Hi Ian you say adult Lonchaeidae are notoriously difficult, are the immature stages easier then? Mark |

Hi Mark adult Lonchaeidaee not too diffivcult to do if you have a microscope - the key characters relate to the number / colour of setae on the body and the shape of the genitalia - however these do not show up well on photographs! so only a very few spp can be identified on this site. Perhaps I was being a bit pedantic by saying adult! - the larvae of most British species can be identified from the shape of the head skeleton - its all laid out in MacGowan, I. and Rotheray, G. E. 2008. British Lonchaeidae. Diptera, Cyclorrhapha, Acalyptratae. Handbooks for the Identification of British Insects, Vol. 10 (15). Iain MacGowan |
