A close up of a small fly on yellow flowers. The eyes are dark red with a white face between and the body and legs are black. The abdomen is tapered and in some of the pictures, you can see a pincer like structure at the end, marking this as a female.

   Rather embarrassed by how bad these pictures are, but this tiny fly was hyperactive & I was struggling to keep my balance 🤷♂️

   But it's an interesting one – a tachnid fly of the Leucostoma genus, with characteristic large white calypters under the wings & a tapered abdomen.

   And this is a female, betrayed by the forceps-like pincers at the end of the abdomen.

   Can anyone ID the species? 🧐
