Description
Summary:Abstract The taxonomy of the Nearctic genus Ophraella Wilcox is revised. Data for all known immature stages are included. Ophraella integra (LeConte) is synonymized with O . notulata (Fabricius). Ophraella dilatipennis (Jacoby) is transferred to the genus Neolochmaea Laboissière.Thirteen species are recognized, of which 6 are new : O . arctica , californiana , communa , macrovittata , nuda , and pilosa . The distribution and host plants of species are as follows : O . americana , eastern North America, on Solidago spp.; O . pilosa , transcontinental along the Canadian border, on Aster , primarily A . macrophyllus O . cribrata , coast to coast in the United States, on Solidago of the subgenus Virgaurea O . conferta in northeastern states, on Solidago with preference for S . canadensis and S . rugosa O . sexvittata in southeastern states, on Solidago spp.; O . notulata in eastern US and Gulf states to Mexico, on Iva oraria O . notata in eastern portion of the United States, on Eupatorium perfoliatum O . macrovittata in the Gulf states, host plant unknown; O . communa in North America and Mexico, on Ambrosia artemisiifolia O . bilineata in the Canadian Prairies and the bordering states, on Chrysopsis villosa O . californiana in California and Mexico, on Artemisia Douglasiana O . nuda in Alberta, host plant unknown; and O . arctica in tundra zone, on Solidago multiradiata scopulorum .The life cycles of most species are still unknown but most species probably have only 1 generation per year. The eggs are laid in clusters on the under surface of young leaves. The larvae skeletonize young leaves and live exposed. Before pupation, the larva spins a loose cocoon and attaches it to a leaf tip. Pupation lasts 1–2 weeks. The newly hatched adults are active on host plants until the early fall, when they enter the leaf litter for overwintering.
