Setostylus bellulus?
Copyright © 2019 Samuel DeGrey

Setostylus bellulus?
Pine Hollow State Natural Area, Sauk County, Wisconsin, USA
Reared this keroplatid out from a larvae. The larvae was your typical highly elongate, mucus web spinning keroplatid larvae.
Using the manual of Nearctic Diptera, I keyed it out to Euceroplatus. However, after reading the discussion here, I suspect it may be Setostylus bellulus.

Update 5/25/19- Keyed it out with both the manual of Central American and Palearctic Diptera, and got Setostylus both times.

Collected as larvae April 5th 2010, Pupated ~May 6th, 2019, eclosed ~May 8th 2019

Dates
Please adjust the dates or remove them. (on each image) The capture date is the only truly reliable date here, but it should only be applied to the larva image.
Are you saying that it was in the pupa for two days or for two months? The way you have it now is confusing, sorry. Otherwise, great work rearing up the little bugger! -- Please update the size fields, thanks!
Please explain: How did you gender this guy? Did you dissect it?

I reformatted the dates. A
I reformatted the dates.

As for sexing it, I assumed that the things poking out it's back were the gonostylus, but after reading the mycetophilid chapter in the MND it seems like this is actually probably a female. I just removed the sex label.
