The cunning Bee-Flies again today because they are really fascinating and for the first time I’ve seen them, with their furry round bodies and extraordinarily long legs and proboscis, in the garden in Sheffield. They are widespread so look out for these Bee-mimics which have a cunning plan to steal a march on Bees and Wasps. These bee-mimics can hover beside flowers and, with their long tongues, reach right into the nectar, even of long-tubed flowers like these Pulmonaria. I managed to photograph another
one hovering about 3 metres above the lawn– they do this to watch for ground-nesting Bee and Wasp nests. What they do next is extraordinary- they fly low, past the entrance to a nest and flick their eggs into the nesting hole. When the eggs hatch, the Bee-Fly larvae parasitise the larvae of the Bee or Wasp, killing them while thriving themselves. Conditions: A glorious sunny, blue-skied day. Temperature: Max 15- Min 6c.
