oak galls on valley oak.Hair stalk gall,fluffy gall and striated volcano gall.
The galls of a California Gall Wasp (Andricus quercuscalifornicus) and a Red Cone Gall Wasp (Andricus kingi), photographed on a host Valley Oak (QUercus lobata) at Mocho Park in Livermore, CA. The gall of A. quercuscalifornicus is the relatively large, round, creamy white object near the center of the picture; it is around 5 cm in diameter and exhibits an exit hole that allowed the cynipid wasp that once lived inside this gall to leave once it had matured. The gall of A. kingi is the small, reddish, cone-like object sitting on top of the Valley Oak leaf that projects out in front of the gall for A. quercuscalifornicus. At around 4 mm in diameter and about 6 mm in height, the gall of A. kingii is dwarfed by the gall of A. quercuscalifornus nearby.
