Development and Ultrastructure:
Zn is Incorporated Late – After Ecdysis:
In the below picture from the top right going clockwise the images show Scorpion, Vaejovis spinigerus 40h, 90h and 160h after ecdysis:
Similarly, Zn is incorporated into ant mandibles, Tapinoma sessile, during the first 100 hours of adult life.
How does Zn enter formed cuticle?
On the left you will see nano-canals and on the right you see the canals.
Zn and Mn are not reabsorbed before ecdysis:
Scorpion stings, Paruroctonus boreus.
