These lovely little solitary wasps have been digging holes in one of the flower beds in the garden. They are known as digger wasps because they dig nests in the ground. The females have specially adapted front legs with a type of brush that is ideal for digging and sweeping away the excavated soil. The burrows look like miniature volcanoes. The females paralyses their prey (e.g froghoppers nymphs) and use these to stock their nests. The burrows can be 30cm long and the end may be divided into two or three branches. The females lays an egg in each. Once the eggs hatch they feed on the stored prey.
Apologies that the quality of the photos aren’t better but they are quite small and a bit camera shy!
