Hey Suzanne, I'll try to get a how to instructions on the gall floats. They are easy to make, finding them is the hardest part.

The grubs are pretty small. They may get bigger as the summer goes on. Some of the floats I made I had to patch because the grub emerged after I had sealed them. I didn't know they wintered in the gall. I may try to find some that are green and dry them to see if gives them a different look.
