Cavariella konoi is a species of aphid in the family Aphididae. It is a small, soft-bodied insect growing to about 2.5mm long. The body is oval, pale yellowish green, sometimes with a pair of darker green, longitudinal bands. Wingless females are found on the leaves of willow Salix spp. during the summer where they reproduce parthenogenetically and form large populations.[1] It also feeds on the perennial plant great angelica (Angelica atropurpurea).[2]
This species has a holarctic distribution.[1]
