Harmless Hornet

Hoverflies, exquisite creatures that are important pollinators of many flowers and whose larvae often feed on plant pests, are usually either overlooked or mistaken for stinging insects.

But one species that is hard to overlook when insect watching, but definitely mistaken for a stinger, is the hornet hoverfly.

At almost 2cm long, the hornet is the largest and most impressive hoverfly in Britain. As its name suggests, it is an excellent mimic of the Hornet, so keeping predators such as birds away, but lacks a sting.

Only a very rare visitor to the country up to the 1940s, in recent years it has become more common in southern England and is still spreading northwards, perhaps as a result of the warmer climate. The adults are migratory so this is a good time to look for them on late-flowering buddleia.
