Abstract
Eggs of six East Palearctic Suwallia Ricker, 1943 species are examined, illustrated, and described using scanning electron microscopy images for the first time. It is suggested that collar morphology characters and chorion punctuations may be considered potential diagnostic features for Suwallia eggs. Keys for their identification are proposed.
