Andricus quercuscalifornicus
The California Gall Wasp is a tiny insect that makes galls on oak trees. These galls are like little homes for the wasp's babies, and they help protect them as they grow.
生息地: Forests
The California Gall Wasp is a tiny, dark-bodied insect, typically black or dark brown with clear, delicate wings. It has a compact, somewhat stout body shape that helps distinguish it from more slender wasps. Its small size makes it hard to spot.
