Sci-fi nightmares play out beneath the flowers

Dunwich Heath, Suffolk Brilliantly coloured jewel wasps use the living bodies of other insects to nourish their larvae

Much of the basic storybook that supplies the raw materials for horror films and novels seems to me to be derived from entomology. And here, at this place of autumn purple and gold, scattered thinly all along the sandy paths that bisect the billowing tides of flowering heather, was a particular inspiration.

It was a tiny 1cm-long creature that looked as brilliant an insect as I have seen in this country. The mid-thorax, hind legs and head were all glittering turquoise, while the abdomen and front thorax were shining burgundy. The unmistakable colours distinguish a small group that are known as jewel or ruby-tailed wasps (in German they are called Goldwespen, gold wasps), of which there are about 30 species in Britain. The commonest is one I see regularly even about our house, where they burrow into crevices among the loose masonry.
