Following form my last post, here are the photos from that feeding great silver water beetle.
You can really see those asymmetrical mandibles in this close up.
Which they use to eat the snail.
It would occasionally uncurl to get some air from the surface.
Before recurling around its wandering pond snail prey.
In this photo is adopting the ‘textbook’ posture with the snail resting on its back.
It was fastinating to finally witness something I had read about, one of those things you see in books, but few people actually see.
Superb sequence and fascinating to see.
