Dieunomia (Epinomia) triangulifera (Vachal, 1897)

Notes

New species record for Arkansas. Common in the central US usually on the alluvial plains of major rivers (Missouri, Arkansas) and their tributaries, east to the Mississippi River corridor and its tributaries in Missouri, Illinois and Indiana, but not recorded any further south along the Mississippi corridor until now ( Cross 1958). A primary oligolege of Helianthus spp. and an important pollinator of Helianthus annuus and commercial sunflowers ( Minckley et al. 1994). Primarily associated with alluvial plains of large rivers, not wetlands per se (Table 1: Site 8).
