Larvae develop in the stem bases of the Broomrapes Orobanche elatior and O. rapum-genistae (Chandler 1975) and affected stems can be recognised easily as the base is markedly swollen at ground level, apparently due to gall formation induced by the presence of the larvae. Puparia may be found in spring and summer in the bases of the previous year’s dead stems. The Pembrokeshire records were in association with the Ivy Broomrape Orobanche hederae on coastal dunes.
