I have about 3 or 4 bird houses on the balcony in various places tucked down in plants (we don't have a way to hang them for birds although that was my original intention), along with about 3 bug houses or logs, and one bumble bee house. Most of them are occupied with various spiders, wood louse, snails, slugs, and other creepy crawly things.
The lid to this one opens on top and this little spider is in there.
