These are the eggs of the dragonfly Aeshna palmata, 25 days since oviposition. The brownish circular area near the bottom is the eye starting to form. The ommatidia in the eyes are starting to be visible. My plan is to follow the full development of the eggs and also get stills and video of the pronymph hatching and the development of the nymph.



Darkfield lighting, Nikon D810, 10x Mitutoyo M Plan APO mounted on a 200mm Micro-Nikkor, f5.6 ISO 64, flash, 72 exposures stacked PMax in Zerene Stacker.

Very interesting subject and study! Thanks for sharing.

Would it be possible to make a stereo pair? With 75 images it might be interesting.
