Appearance

Poison ivy gall mites form small red pouch galls on the upper surface of the leaves of their host. The mites themselves are extremely small and are usually found in the interior of the pouch . The bright coloration they create in their host plant, however, makes this species fairly conspicuous and easy to detect compared to other members of ''Aculops'' . Due to this, this species is one of the more widely reported species in its genus although like many of its relatives it is still poorly known.
