Share 'An early spring insect - the Greater Bee-fly (Bombylius major) feeding on Caltha flower in pond, April 7th '19.'

This fly parasitises other insects like solitary bees and wasps, flicking her eggs into or near the nest site of the host species. The bee-fly grub that hatches then feeds on both the eggs or larvae of the host as well as on the host's stored food supplies intended for its own offspring.
