Syrphus ribesii (Linnaeus, 1758)
Biology & ecology:
The larva is commonly found feeding at all sorts of ground layer and arboreal aphid colonies. Overwintering larvae can often be found in leaf litter below aphid-infested Sycamore Acer pseudoplatanus trees. Occurs in most habitats, including woodland, farmland and urban parks and gardens. Adults rest on sunny vegetation and visit flowers of all sorts. The males hover amongst the canopy of woodlands and are responsible for the audible whine that can be heard in mid-summer. This species is multiple-brooded, and so has a long season.
One of the most widespread and abundant hoverflies throughout Britain.
Status & conservation:
The frequency of occurrence fluctuates greatly from year to year, but there is no obvious long term trend.
