Chrysogaster cemiteriorum

Chrysogaster cemiteriorum (Linnaeus, 1758)

Nomenclature:

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.

Distribution:

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.

Recorded from 339 hectads since 1990.
