Empidid fly

Empis tessellata


Empididae is a family of flies with over 3,000 described worldwide. While mainly predatory they can often be seen visiting flowers to obtain nectar, as shown here. The flower is the Great masterwort, Astrantia major. Common names for members of this family include dagger flies (see the sharp piercing mouthpart on this species). See notes for identification.

Lovely shots... yes looks like E tessellata ♀ to me. Seems many are mis-IDed with E opaca on leg colour.
