This is a rare species in our area.  Please provide good quality photographs to support your record.  It would be advisable to retain the specimen until confirmed by the County Recorder.

Dry, sandy places, waste ground and dry pastures.

The main flight period is between June and early September.

The larva feeds on dock species, particularly Curled Dock, feeding internally on the roots and stems.

Nationally scarce but may be increasing in numbers.  Its present strongholds are in East Anglia and Southern England.
