Quite common here in Malta - every Garden almost - bit scary at first with their legs dangling.
No interactions present.
I'd like to agree and may well do so soon.
Though I see there are a few lookalikes on the Web Graham.
And I wonder why the name is not recognisable for the normal ID panel links - Wiki, EOl etc.
The name "Thread-waisted wasp (subfamily Sphecinae) - ANY of a group of large, common, solitary (nonsocial) wasps in the family Sphecidae (order Hymenoptera) that are named for the stalklike anterior (front) end of the abdomen." is from Encyclopædia Britannica Remember that? All those volumes!
If we call it the Mud dauber wasp and search the web, you will find UK records too.
Fascinating vid. here
