Quite possibly our strangest observation on the Hills so far: Whilst trying to ID a species of Slug (Arion spp) within woodland area, we noticed a small fly that appeared to be attracted to use of Flash photography. This individual was approximately 5mm in length; appeared to be quite mobile, clearly unable to fly but managed to hop short distances. This individual was photographed on the edge of stem (Photo 2) and then inextricably launched itself onto the coin, becoming stuck to the slug (photos 3,4,5). We carefully extricated the fly and it did appear to be fine thereafter (Photos 6,7). It was only after downloading photos that we were able to see closer detail of body: Note vestigial wings striped thorax, and hairy yellow abdomen. We have reached the outer limits with research on this observation and doesn’t appear to fit examples of Drosophila (Trip down memory lane & A-levels - recessive genes). Would welcome support and advice. See ID notes & Comments.
