Episcopic

In reflection (epi), first we have brightfield, then darkfield, and finally with Disco Lights Illumination (epi-Rheinberg).

Diascopic

In transmission, I used a 40x LWD HMC objective (long working distance Hoffman Modulation Contrast). First is brightfield, then two HMC views and finally with crossed polarizers.

Finally, a small .GIF (654 KB) animation showing the living worms inside the eggs. All these photos were taken after about 12 hours after collection.
