Parasitic biology
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.
