Hi, I have not visited here in a long while.. but here is something interesting.

Many centipedes glow under UV light to some degree, especially legs/terminal legs and often antennae. Although not to such a degree as scorpions, of course. But embryos do flouresce strongly and it seems now that this is only during early stages. I did not know of the 'honeycomb' detail on the outer layer until these photos :)

Please let me know if this topic has been discussed before as I am interested to learn more.. and to know if someone has noticed this before (I hope)

The ocelli are a-glow, as well. I wonder if that is the exterior of the ocelli that glow, interior fluids or just a reflection?

Doesn't at all look like reflection to me.
Thanks for sharing!

Cheers! :)

yes I would imagine its the fluid inside ocelli. I hadnt really paid much attention to that but I will see if this is consistent with all my centipedes (i would assume all their ocelli will glow).

Anyway I played around with the photos a bit more and came up with this to show the detail better in black and white, like they do in scorpion taxonomy. I am wondering if the 'honeycomb' structure is rigid or just dimples. If anyone knows details of the embryonic development please speak up. I am assuming the thin slime sheet that is shed once pedelings 'hatch' remains the same throughout development. So probably that slime sheet is made of tiny patchworks woven together.

I seem to vaguely remember something about egg structure from Lewis' Biology of Centipedes, but can't say for sure and unfortunately don't have a copy.
