A worldwide community photographing and learning about wildlife
I saw two mud balls in a branch (photo # 3 and 4), about the size of a marbel. From PN I knew they were Potter Wasp Nest. I had never seen one before. Later I found another one "open" and I could see a green caterpillar inside. The nest is mud made of a mixture of earth and regurgitated water. When a cell is completed, the adult wasp typically collects beetle larvae, spiders, or caterpillars and, paralyzing them, places them in the cell to serve as food for a single wasp larva. As a normal rule, the adult wasp lays a single egg in the empty cell before provisioning it.
Arid place.
I didn't see the wasp.

Gracias Marta
que linda estructura!
I agree Sergio.
I guess that the wasp came back soon, to close the opening. It wouldn't abandon the nest after all the work it had to put that caterpillar inside it.
Just a minute Sergio because I saw a butterfly and I went after it.
How long did you stay around the second nest, Luis?
