A strikingly marked yellow and black striped hoverfly which I came across feeding on the nectar of a thistle on the edge of a local field. These adults grow up to 15mm long.
The terrestrial larvae feed on aphids, and the adults feed on nectar.
Seen March to November, and found almost anywhere, including hedgerows and gardens. One of the commonest and most widespread of Britain’s hoverflies, and can appear as migrants in huge swarms.
