Tool-using Wasp?

At Duck End Nature Reserve this afternoon, 1st July, an Ammophila sabulosa found this caterpillar and dragged it back to her burrow. She then spent some time enlarging the burrow before dragging the caterpillar in.

During the enlargement process she briefly wielded this pebble seemingly like an hammer bashing the opening before discarding it and digging again with her feet and jaws...


Once the caterpillar was housed the hole was filled in, using her head as a vibrating ram - I could hear her buzzing as she packed the material hard. Small pebbles were finally arranged over the surface.

Hello Keith,
Discovered your blog while serching in google for tool using wasp...
Anyway about 20 years ago I observed a wasp using man made sewing needle to send a big cockroach in a small hole... I don't know if the ability of wasps tool using are frequently observed. Perhaps not. Google result does not say that... Anyway there is not many thing about yourself in your website...
