The chipmunks and squirrels eat hundreds of the beetles. 
They must go out in the rain to dig them from their holes.

Cynips weldi sp. nov. : 
Female: Head black, surface microscopically crackled with numerous 
large, deep punctures and covered with whitish hairs. Antenne 14-jointed, 
clavate and pubescent. Thorax black, somewhat shining, surface micro- 
scopically crackled with numerous large, pit-like punctures and rather 
densely covered with whitish hairs. Parapsidal grooves continuous, broad- 
est at the scutellum and very fine forwardly. They are widely separated 
at the scutellum and curved inwardly before they reach the collar. Me- 
dian groove wanting, only very slightly indicated at the scutellum. Ante- 
rior parallel lines very fine and scarcely extending to the middle of the 
pronotum. Lateral grooves rather long, running well forward to beyond 
the middle of the thorax.. Pleure rugoso-punctate, opaque. Scutellum 
black, finely rugose with pit-like punctures, basal fovea large, deep and 
shining. Abdomen black or piceous, glossy with dense whitish hairs at 
the sides. Legs black or piceous, with whitish hairs, femora with large 
punctures. Wings hyaline, radial area closed. Cubitus faint and not 
continuous. Areolet large. Length 3-4 mm. 
Gall: On the underside of the petiole of the leaf of white oak (Quercus 
alba) at the junction of the leaf blade, July to October. A rounded ball- 
like cluster of bright red or brownish galls closely pressed together and 
out of shape. The individual gall is rounded or tuberculated on the sum- 
mit, flattened at the sides and pointed at the place of attachment. It is 
solid when fresh with a single barely visible larval chamber in the center. 
Late in September and in October the galls become detached, drop to the 
ground and the larve continue to feed therein. The gall gradually changes 
its shape and becomes subtriangular or polyhedral and may be taken for 
that of another species. The outer shell becomes thin, soft, darker in 
color, and the inner part is eaten away until only a hard and woody shell 
remains. Diameter of clusters 8-20 mm. Individual galls 5-10 mm.
