I took this shot today in my garden in Wolverhampton, UK ... this fly was crawling all over the black fly on my nasturtiums (I presume collecting their sugary nectar, like ants do) ? would this be Lucilia caesar, or are there similar species in the UK?

Quite a few similar species  A smaller photo would be better too - try to keep 640x480 pixels or less if you can  |

Hi Jez, nice to see you back. It's L sericata, female, by the look of it. (Pale basicosta, single ad on mid-tibia, very widely spaced eyes.) 3 post sutural acr preclude L caesar, which only has 2. Also sericata is much more likely than caesar to be found in an urban habitat, and is by far the most commonly encountered Lucilia species in my experience. Basicosta - where the wing joins the body. ad - a single forward pointing bristle on the middle tibia. Post sutural acr - the pair of bristle rows running lengthwise down the middle of the top of the thorax. The suture is the crease that runs across the thorax from just behind the forelegs. Susan |
