Recently, we have been noticing (how can you miss the really?) cicada killer wasps flying around in there. I haven't yet found their nest, but there is at least one by our windows every day. I think they are getting stuck or else they are already on their last legs since it seems that they drop dead within 24-48 hours of being in there.
This week, there were two or three in the sunroom at once, and it seemed that they were attacking a butterfly that had gotten waylaid as well. The drama outdoors makes for interesting viewing - thank goodness it has given us something to do when it is super hot in the afternoons!
