Chrysogaster virescens Loew, 1854
Biology & ecology:
The larvae of this genus are aquatic, but the larva of this species remains unknown. Associated with boggy, acidic locations with carr, wooded stream-sides or damp scrub. Adults are frequently found at flowers, including those of Rowan Sarothamnus scoparius, white umbels Meadowsweet Filipendula ulmaria and buttercups Ranunculus sp.
Although widely distributed, this species appears to occur mainly in the north and west, and is locally frequent in the Scottish Highlands. In the south-east it seems to be confined to acid heathland locations.
Status & conservation:
There has been a significant decline in occurrence from most parts of Britain over the past 25 years, but there is some evidence for an increase in occurrence in upland areas.
