Wool Sower Wasp Galls
White Oak
A tiny wasp stings the stem and deposits eggs. The eggs command the tree to grow a specific structure that encases and protects the larvae. Inside the gall the larvae look like seeds packed side by side with fuzzy tails. The cycle takes two years to complete. Though strangely parasitic, it doesnβt hurt the trees.
Another wasp evolved an ovipositor to sting the larvae within the gall and deposit eggs on THEM. Parasites have parasites.
