Mottled arum aphid
sexual stage in the life cycle. Wingless females of the mottled arum aphid are shiny whitish, yellowish or green with black cross bands behind the head, broken [...] along the midline, and a large horseshoe-shaped spot on the back of the abdomen. These black markings can be highly variable. Adult females are 1.2-2.6 [...] Immature Neomyzus circumflexus are usually the same background colour as their parents, but they lack the characteristic black markings.
