Oak leaf galls on live oak

Description:

Description: Two kinds of galls are produced by this wasp. The most notable are produced by the asexual generation that are spherical, corky, 1/8 to 1 inch in diameter and appear on twigs and branches of live oak in late summer and early fall. When first formed, they are pink to pinkish brown and the yellow-green tissue inside is moist and soft.

Habitat:

Miller Springs Park is a 360-acre park located below Belton Lake, on the Leon River, in Bell County, Texas. It contains diverse riparian terrain, including limestone bluffs, estuarial wetlands, mountain cedar hilltops, and riverside cottonwood stands. Numerous trails traverse prairie-like open spaces and forests of native cedar elm, live oak, and red oaks. Recent floods have created a new canyon that reveals numerous layers of sedimentary rock and fossils. Area wildlife includes white-tail deer, red foxes, coyotes, black squirrels, armadillos, and about 200 species of birds in the course of the year.
