Funny you say that, Treehugger. Something similar has been happening for me.
Background: I have a screened in back porch that I love. We've propped the screen door open so that my dog can come and go as he pleases, but that means wasps can, too. I'm allergic to their stings, so I always get scared when I see them despite the fact that I know better than to respond that way. It's just a body-thing. So this one wasp keeps coming into the porch, and then it gets stuck in there, not being able to figure out how to get past the screen.
I just can't bring myself to kill things just because they're inconvenient for me, so I have a trick wherein I cover it with a cup, slide paper underneath, take it out and fling it madly so as not to have it blow back on me.
Now to the meat of the story: I started watching him try to come back in a couple of days ago, and I was mentally saying ,"No.. no.... no...." I saw him almost passing the threshold, then he'd pull back. He did this several times and flew off. About the third time this happened, I realized I must have been communicating with him on some level! He was actually feeling the barrier and either respecting my wishes because I hadn't killed him, or he didn't want to get stuck in there any more than I wanted him to.
Pretty cool.
