Explanation of Names
Author: Osten Sacken, 1865
Food
Larvae develop in galls on scrub, water, pin, and red oaks. (1)
Life Cycle
Females emerge from twig galls in spring and oviposit in leaf veins, causing small vein galls. In midsummer, adult males and females emerge from these galls and mate. The females then oviposit in twigs, causing the large "horned" galls. These take about two years to reach full size. (2)
