Name this Fly

First attempt  at doing a focus stack with microscope images.

Last week a began setting-up for taking images through a second-hand microscope that I obtained many years ago. This is not a great photograph, but it is my first attempt at a focus stack using images made through a microscope. I have since found out a few ways that should improve the quality, but I thought I would post this to see if any Dipterists out there could figure out the ID from just the genitalia. Any takers?

Originally I was going to name this post “Name these Stacked Genitals”, but I don’t really want to compete for popularity with the Beetle-poop Geek. 😉

More details on the equipment/techniques (and lack there-of) later.

    I’m glad you specified genitalia, because my first thought when I saw the photo – knowing only that it was a fly – was that it was the larval head of some carnivorous species with terrifyingly developed mandibles!

      They are a bit scary.. definitely looked designed for grappling, if not puncturing!

    This is a pretty tough challenge Adrian! I really have no clue, but I’m going to guess something in the lower Brachycera, perhaps Asilidae or Rhagionidae? Definitely not going to venture beyond that level of ID…

    Looks to me to be Sciaridae

    Matt is right, with BugGuide naming the fly as a Dark-winged Fungus Gnat (Sciaridae). Thanks!
