aphidman's Identifications

Collection 7159.2. Appeared in a collection of leaf curls of Symphoricarpos albus made by Cedoaphis, so I assume these are alates.

Original observation: https://www.inaturalist.org/observations/216702177

1. Extreme aphidosis on terminal parts of branches of Symphoricarpos alba. Forming clusters of leaves enclosing a largely empty chamber. most terminal leaves are reduced and red. several plants had many of these 'balls' resembling brussel sprouts. aphids tended by ants.
