Phyllocoptes populi


    Phyllocoptes populi is a mite that causes galls to form on the leaves of Aspen and very occasionally on other members of the Poplar family. The gall has a distinctive yellowish bulge on upperside; (filled with hairs that the mites live in between). The hairs below are pale at first, reddish or brown later, each broadened at tip. The galls are seen more often than the mite.
