Mud-Rolling Mud-Dauber

Georgina was at the waterhole early to photograph birds, but her attention was diverted to these industrious wasps. They were busy at the water’s edge, rolling the soft mud into balls and carrying them to their nearby nests. For a good angle, she lay in the mud, then pre-focused on a likely flight path and began shooting continuously.

The female mud-dauber wasps use the mud balls to build their nests. Collecting them into clusters, they then carve chambers inside the balls into which the females lay their eggs. Before closing each one up, the wasps insert the paralysed bodies of orb-weaving spiders as food for their larvae when they hatch.
