Sand Wasp Versus Caterpillar

 The Sand Wasp, Ammophila sabulosa, preys on caterpillars (here Silver Y caterpillar) which it paralyses, takes to a pre-dug hole and places in the burrow laying an egg on it. The egg hatches and the larva feeds on the caterpillar. Carrying such a large prey is no mean feat especially over rough vegetation. When it reached the hole an amusing sequence occurred as it attempted to push the larva into the hole (like threading a needle with a floppy piece of cotton) but eventually worked out it is better to go down the hole and drag it in.

Sandy Bees, Wasps and Friends

On Monday afternoon, we transferred to the Beewolf Wasp colony nearby. Unfortunately, the rain came as we arrived but was not heavy enough to stop photographing and we spent an hour or so with the Sand Wasp (Ammophila sabulosa), Pantaloon bees (Dasypoda hirtipes), Common Blue Damselfly, Red-legged Bug and Field Grasshopper. The weather then brightened and activity started on the mound with Beewolf Wasps and Pantaloon Bees busy digging out their burrows. We saw one wasp carrying its honey bee prey but by then it was late in the afternoon
