Wasps

It's amazing the assortment of wasp species around, each with its own style of nest. I discovered the ones in the attached image in the Pau Brasil tree next to the reception center. I've seen lots of engineering feats in that tree over time, I guess because I show it off as one of our stars, in terms of famous trees. It seems that each new nest is different than the old ones. This one isn't very noticeable because it looks a lot like a dead piece of a tree branch, or a dead leaf all curled up. Very large wasps and a small elongated nest. Quite a contrast. I assume that these wasps build the cells for their larva only. I see no way that they could share the space.
