It, and another similar wasp (this may even be the other one) repeatedly worked over the flowers of a figwort. On one occasion an unfortunate hoverfly was enountered on a flower and quickly dewinged and digested. (I'll spare you the photos).

Digging them out...
Saturday, 19 July 2008
Earlier, while looking at DENR's wasps, this ruby-tailed wasp Hedychridium roseum (probably), was searching for something, presumably prey or mate...
This wasp, probably Diodontus tristis, dragged it's aphid prey (which gives some idea of scale - this is a small wasp) to its burrow, where it got jammed in the opening for a few seconds!

Once the debris that had hidden the hole had been cleared the caterpillar was dragged in:
Once an egg had been laid on the prey the process of filling in the burrow began:
This was an intra-species crime and the DNA of the thief will prevail in this case. Was the thief the same wasp that had fought earlier and had bided its time for over forty minutes to take the spoils? Fascinating. You can see why the Ammophila genus has been much studied.

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.
The Marbled Whites weren't very obliging either. These are the best I could grab...
