? What makes this one S. scripta, when there have been other obs submitted as that, then demoted to just Sphaerophoria, are there other spp around?
It's a male (eyes touching) and scripta can be told from all the other species, as a male, because the wings only reach about half way down tergite 4. In other species, they reach the end of the abdomen, pretty much. Females cannot be taken to species with confidence.
