Now we are in high summer and the temperatures are reliably warm, some of our biggest insects are emerging. This year seems to be a good one for the rather uncommon hoverfly Milesia crabroniformis. This huge fly is a hornet mimic, and one of the best. It is completely unthreatening though, unable to bite or sting, it just flits from flower to flower sucking nectar, pollinating as it goes.
Anyone care to guess how I can be sure one is male and the other is female from these photos? The answer is staring you in the face!
