I think spring is well and truly here. On my walks I am now seeing lots of insects that I remember from last summer, such as scorpion flies, longhorn moths, frit flies, and Tachina fera. I am also seeing some, like the above soldier fly, that are completely new to me. It is a male, probably of species Microchrysa polita (Diptera: Stratiomyidae), based on a good match with the photo here. The only similar species I have come across is Microchrysa flavicornis but that has yellow, instead of black, antennae.
