Wasps strengthen home security

On my walk through the yard this morning I saw this.


The wasp was obviously concerned about home security and had installed an impressive lock on the entrance to its nest.

I pointed it out to the tall person and asked if this was a response to a possible spate of burglaries on wasp homes in the neighborhood. He smiled and told me that it is a key hole on one of the doors in our yard and not a wasp home.

Hmm. I was wondering how the wasp would be able to carry its keys.
