Description and notes
Identification keys and general biology are give in Morgan (1984), Kunz (1994) and Mingo (1994).
Cornwall to Kent and north to East Norfolk. There is one old record from North Wales. Found in the Channel Islands but not in Ireland.
Overseas, occurs in many parts of Europe (Norway, Sweden, Finland, Denmark, The Netherlands, Belgium, France, Spain, Germany, Switzerland, Italy, former Czechoslovakia, former Yugoslavia, Greece, Cyprus), North Africa and Asia (Uzbekistan, Siberia and Manchuria).
Status (in Britain only)
Not listed in either Shirt (1987) or Falk (1991); however, work for this Atlas suggests that its status should be reviewed.
Found in open sandy areas associated with the nesting habitat of its host (see below). Present on inland sandy areas including lowland heaths, and coastal sandy areas.
Probably univoltine; July and August.
Wild carrot (Daucus carota), sheep's-bit (Jasione montana) and yarrow (Achillea millefolium).
No information available.
The hosts of this species are the Crabronid wasps Astata boops (see Map 083), Tachysphex pompiliformis (see Map 087) and Dienoplus tumidus (Morgan, 1984, as Gorytes tumidus). However, the distribution of A. boops and H. roseum are so similar in England that A. boops would seem to be the main, or even the only, host. For further information see H. ardens.
