Wonderful photo of larva and gall. I'd never heard them called "oak apples" - love it! We have several of them in the trees behind us - also found one yesterday near our son's soccer field, but I think it was on a maple leaf, is possible?? Would it be the same wasp? Do they only go after oaks? Are all galls are caused by wasps? Or can you only properly call something a "gall" if it was made by a wasp?

We have a ladyslipper blooming just beyond our back deck - we feel extremely excited, secretive, and slightly smug about its presence. ;) There are many at the nearby Francis Carter Preserve, too. I can now spot them even before they bloom - they seem to occur in groups, so if we find one it's suddenly a scavenger hunt to find another, and another..... :)
