Hedychrum niemelai - A ruby-tail wasp

Range & Status

Found in a variety of sandy localities; lowland heaths, coastal dunes, and cliffs with sandy deposits. Once considered to be a national rarity of southern heathland and sandy areas on the coast, it has in recent years been found to be much more common and widespread than previously thought. Work for the aculeate Provisional Atlas' suggest that its status requires review. It is known from at least 12 post 2000 sites along the Cornish coastline, both north and south coasts. A cleptoparasite of Cerceris spp. of wasp.
