Acraspis insolens

Hosts: Quercus chrysolepis

[A photo of the gall appears on page 69 of the pdf]

Gall. (Fig 209). Monolocular, wedge-shaped galls on the underside of leaves. The galls are up to 10 mm long, 5 mm wide and 3 mm thick, concave on the two broad sides, deeply grooved around the edge, nearly the color of the leaf, the flanges often reddish. The larval chamber is located transversely at the apex of the gall and a long cavity runs through the center of the gall from the chamber towards the pedicel (Weld 1926).

Biology. Only the asexual generation is known, inducing galls on Q. chrysolepis. Mature galls are present in September, adults totally formed in November, overwintering in the galls, emerge next spring
