parasite

The aphids live in large populations at the upper side of the leaf disc, mainly at the base.
They occupy the highest leaves, that roll inwards lengthwise; this causes the leaves to stand out stiffly, rather than to droop. Occupied leaves display striking yellow length lines.
A striking character of this species is the possession of a second median terminal appendage, right above the cauda.
