A new house...

Ok, last year we had some trouble with wasps in the backyard. So we got this yellow "wasp trap"-thing. It hung in the tree by the patio all season. We never saw one single wasp fly into it. It stayed empty.

Today we noticed that a wasp was building a house. Inside the "wasp trap". Flying happily in and out with building material.

We don't think that was the purpose of it...

(yes we know there are different kinds of wasps, such as the yellowjackets, or the hornets... and this is probably a hornet in trap for yellowjackets or the other way around...).
