t's raining galls! Galls of the mealy gall wasp are falling out of the southern live oaks all over Houston. As you can see, a lot of them are damaged, as though something tried to eat the larva in the center chamber.

I don't know what they were catching, but several fish species live in that bayou. I've mainly seen carp and armored catfish
