A good quality close up photograph is required to support your record.  It would be best to retain the specimen until the County Recorder has accepted the record.

Grassland and flower rich meadows, especially where Scabious species are present.

Flies in two generations between late May and early October.

Larva feeds on flowers and seeds of Devil's-bit Scabious, Field Scabious and Small Scabious.
