Segmented black fly on Gorse.
No interactions present.
This is probably Bibio lanigerus, as the stigma is pale brown and the body hairs are long and pale. The posterior veins are pale on the wing and the rest of the venation fits for lanigerus. However, a specimen under the microscope is always the way to a certain ID.
lanigerus has been the commonest I have been taking through March and the first week of April, but johannis seems currently to be the commonest species around my sites.

Thanks! As I stick to field photography I will probably always be limited to "Bibio" with these. (Except B. marci!)
