I see this brightly coloured hoverfly most places, including in my gardens and in local hedgerows. A distinctive black and yellow banded hoverfly, with a yellow face and slender body. 16mm long. It maybe confused with Syrphus vitripennis.
There are three generations per year, and they overwinter as cold-tolerant larvae. The larvae are avid predators of aphids, whilst the adults feed on nectar and are very important pollinators.
Seen April to November, and found almost anywhere, including gardens. Common and widespread.
Photographs taken June 2010, May and June 2014, and April 2015, Staffordshire.
