Abstract

Many of the small leafhoppers that feed and reproduce upon the foliage of birch trees belong to the subfamily Typhlocybinae. The main species are Typhlocyba hockingensis Knull, T. pomaria McAtee, Ribautiana foliosa (Knull), Edwardsiana bergmani (Tullgren), Empoa latifasciata Christian, Dikrella cruentata (Gillette), Alebra albostriella (Fallen) and several Erythroneura species. Their ecological requirements and life histories are described. Notes on morphology and illustrations of each species except the Erythroneura are included.

Résumé

Parmi les Cicadelles qui se nourrissent du feuillage des bouleaux et s’y reproduisent, plusieurs appartiennent à la sous-famille des Typhlocybinées. Les espèces principales sont : Typhlocyba hockingensis Knull, T. pomaria McAtee, Ribautiana foliosa (Knull), Edwardsiana bergmani (Tullgren), Empoa latifasciata Christian, Dikrella cruentata (Gillette), Alebra albostriella (Fallen) et plusieurs Erythroneura. L’auteur décrit leurs habitudes écologiques et leur cycle évolutif annuel. En outre, il traite de leur morphologie et toutes, sauf les Erythroneura, sont figurées.
