I had previously worked on some flies for a fantasy army, and this project was quite similar.
Sgt Slag 
suggested using "a pearlescent green nail polish" for the eyes. I liked the idea, but didn't want to mess with nail polish. Fortunately, I discovered that Dollar Tree had Ceramcoat Metallic Lime Green paint.
I glued the flies to the 50mm-square bases I made in the previous article, and applied the lime-green metallic paint to the eyes, not bothering with any primer. Two coats achieved good coverage, then I tidied up with black. I also decided this time to drybrush the fly body with dark gray to bring out the details.
And here are the finished flies.
In 15mm scale, they are humongous.
I didn't apply a sealer coat, as it didn't seem needed.
It perhaps would have been more in the spirit of Alien Squad Leader to have multiple flies per base, but I didn't have any smaller flies that I liked.
Similarly, since these are flying creatures, I considered trying to create a flight stand for them, but realized these models are not in a flying pose.
