May 3rd – It’s always interesting to watch the variety and spread of oak galls on the trees I pass.

At the moment, rosy red oak apples are developing well, corrupted from leaf buds by the tiny wasp who laid her egg in the bud. Her larvae will hatch inside, done on the inside of the gall and drill their way out when mature.

Fascinating things that don’t harm the tree and continue a millennia old relationship between oak and parasite.
