Chrysogaster cemiteriorum (Linnaeus, 1758)

Identification

Identification difficulty = 3. microscope_icon camera_icon_question according to Ball & Morris, 20241

Synonymy

Chrysogaster chalybeata Meigen 1822 in Stubbs & Falk (1983)2.

Biology

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 the much more abundant C. solstitialis.

Flight period

The following plots show the number of unique records per week excluding those reported to be of immature stages. Phenology plots for Chrysogaster cemiteriorum

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.
