... also had lot's of Queen bumblebees wandering in, getting stuck and needing rescuing. Wasps seem to be more intelligent, and can find their way out again without assistance.

There's a reason for that, Andy. I only found out recently but, apparently, wasps have excellent eyesight but bees have lousy eyesight!

Bees have excellent directional skills and can communicate good sources of nectar to other bees in the hive - presumably they rely on smell and swathes of bright colour to home onto the flowers themselves. Perhaps it is only their distance vision which is poor and they have excellent closeup vision for navigating inside the flowers?

I certainly don't think wasps are intelligent, they just aim for the light. They then fly into the window pane, buzz around for ages, completely ignoring the open window that they used for entry a couple of inches away, then fly around the room for a bit and repeat the operation, colliding head on with the same window they hit previously!

That reminds me - I must find out what happened to my electronic bat  when we moved - I haven't seen it since.
