Such creatures lives on a sandy beach of my pond.

These are cousins of well known common earwigs. I'm not entirely sure if the ID is correct, but I think this could be Sand Earwig (Labidura riparia).

They are bigger than the common earwigs (20-30mm) and are painted in the colours of sand. They are primarily predaceous, seldom feeding on plant material.

All earwigs are great parents.
Their care of the eggs and young fascinate many entomologists. Earwigs are subsocial insects, meaning that there is parental care of the young, but not cooperative brood care. The nest of the earwig is a short tunnel dug in the ground or a natural cavity, often adjacent to a rock. Most commonly, the nest has two chambers. Males may occupy nests with females for a short time (the honeymoon, so to speak), but are expelled after the eggs are laid.

The female very actively busies herself with the eggs, and unlike Hymenoptera which pretty much leave the eggs alone until they hatch, earwigs clean the eggs often and re-pile them. The female may even move them to different parts of the tunnel. Eggs are often moved in contact with a stone, if indeed the nest is adjacent to a stone surface. That movement of the eggs may be for temperature regulation, but this has not been shown conclusively.

Eggs that are not tended have a much lower survival rate than eggs that are tended. If the female is not present, the eggs are soon attacked by mold. Females not only clean mold off the eggs, but deposit a fluid on the egg as well. They do not seem to recognize the eggs as distinctly their own, but will tend eggs or even foreign objects introduced into the nest. Damaged eggs are eaten.

The female defends her nest vigorously, but if the nest is disturbed repeatedly, she will eat the eggs and abandon the nest.
After the eggs hatch, the nymphs remain in the nest for a time. They are fed by the female but also begin to forage for themselves early on. The female brings food back to the nest for the nymphs. If the young of another earwig enters the nest, the female accepts it as her own, just as any young of hers that wander into another nest will be equally accepted.

Maybe there will be another occasion to write more anout this fascinating creatures.

Good shot Monika, and I like your POV. Having the earwig so centred is just right here. You show him very clearly, great clarity and colours. Well done - BRAVO!
