This species has now been reared from upper stem galls in V. alternifolia and V. occidentalis (L.) Walt. from western Cades Cove with adults emerging in May through September. Amnon Freidberg also reared two specimens (USNM, TAUI) of this species in 1993 from galls on V. alternifolia from Washington, DC, Rock Creek Park (A. L. Norrbom, personal communication). These are new host records for E. rotundipennis. Verbesina alternifolia appears to be the preferred host with V. occidentalis utilized only late in the summer. (p.3)
