Chrysogaster cemiteriorum (Linnaeus, 1758)
Chrysogaster chalybeata Meigen 1822 in Stubbs & Falk (1983).
Biology & ecology:
The larvae of this genus are aquatic, but the larva of this species remains unknown. Adults are usually found in wet meadows, fens and valley-bogs where they visit flowers, especially white umbels, but they can also be frequent in damp woodlands were they should be sought amongst C. solstitialis.
Widely distributed but rarely common. Primarily occurs south of the southern uplands of Scotland. There are also a few records in north-east Scotland. The patchiness of this species' distribution, such as apparent absences from parts of eastern England and from much of Cumbria cannot be readily explained.
Status & conservation:
There has been a significant decline in occurrence from most parts of Britain over the past 35 years, except in uplands where occurrence appears to be increasing . However, this is a wetland species and this assemblage shows a general pattern of decline.
