Andricus stropus n. sp.

The Leafy-wreath Gall

Galls.--A diminutive, brown, acorn-shaped gall, issuing from a bud axil, surrounded at base with small, narrow, dense leaflets. The gall, itself, when removed from its leafy matrix is oblong-oval; in height .15 inch; diameter through .1 inch, and has a little nipple on top. It, too, drops to the ground, but unlike the other species just described, there is but one cell to each gall.

Andricus stropus (Ashmead 1887)

Hosts: Quercus chapmanii
