Eumerus sogdianus Stackelberg, 1952

Identification

Identification difficulty = 5. microscope_icon camera_icon_cross according to Ball & Morris, 20241

Biology

The larva are associated with potatoes and Allium bulbs but there are also rearing records from the roots of wild carot. Adults appear to be most frequent on grasslands on free-draining soils, but a close association with the edges of reedbeds has also been reported. Adults are reported to visit the flowers of umbellifera and have also been seen at Wallpepper Sedum acre.

Status

This species is likely to have been accidentally introduced in association with agriculture or perhaps food importation, and might logically be watched for in areas where such crops are grown.

Distribution

Added to the British list by Wright (2013)2 from the Isle of Wight. There have subsequently been a small number of records from southern coasts. dotmap
