        On Birches (Betula spp.), more than seventy species of aphids in eighteen genera are recorded worldwide, mostly (> 60%) belonging to ten genera of the subfamily Calaphidinae (Hemiptera: Aphididae). In Korea, only seven Birch feeding aphids are recorded. Recently, we recognized two calaphinid species, Calaphis betulaecolens (Fitch, 1851) and Euceraphis betulae (Koch, 1855) as new to the Korean peninsula.
