The M vein? is curved upward. Plus the species is very dark with a reddish-brown tip of the scutellum. Thank You for your Time. Edit: Sir Stephane has identified this specimen. I will add more photos sometime to complete the post for future reference. johnes81 attached the following image: [109.35Kb] Edited by johnes81 on 17-10-2017 20:40 John and Nini.

I may not get it under the microscope until next week. I'm just happy to know where to begin with the keys. Even better that you suggest levida. Thank You. John and Nini. Naturalists not experts.

You can remove the "cf" for this one as M. levida is the only species to have this very broad r5 cell at apex (other characters are : palpi, antennae and basicosta and legs all black - there is some yellow on other species). Stephane.

I asked my Wife to look at the keys and she mentioned the palpi and antennae being black. I told her that you had mentioned levida and that you are probably correct without seeing a decent photo. Once again, Thank You very much Stephane. You've saved me alot of time. I have some Pollenia to examine, so I have no free time this week. I hope to make time for this by Saturday. I am excited to have my first Muscina under the microscope... John and Nini. Naturalists not experts.
