Mark noticed the bees' chain was quite strong - he was scooping a swarm
with his hand into the box and he had to pull really hard to separate them
from the cluster. They were all connected.

No one knows why bees chain, also called festooning. The general view is
it is *something* to do with comb building - measuring space? Figuring
how deep they can make a comb for a given width of cavity?
A related theory is that by forming thick ropes of bees they are warmer,
which helps express / mould wax. However, new cells are added at the bottom
edge of a comb, not built in free space, so that doesn't quite make sense!
Torben Fischer, using an endoscope, noticed multiple chains below a wild
nest, between the lower edge of the combs and its entrance. He realised
this could be a way of guarding the entrance, like a spider's web. He
pushed a wasp in, it immediately hit a chain of bees and they mobbed it.
But that would only function as a "web of guards" in a wild nest if the
entrance was *below* the combs, which it often is not.
Another possibility is there is some subtle air-current sensing going on.
"Let's try blocking the air here a bit... yeah that would guide it how we
want it further up the nest... right let's twist the next comb in that
direction."
So my feeling is that it probably performs a number of functions. It may
even be a fun social pastime! Which gang can build the longest chain!

I do hope that theory is real. My understanding of it is that the
chaining measures out the curved comb shape. Do we know?
From an engineering perspective I
I’m right in saying it’s all about parabolic catenary curves - I.e. the
shape you get if you hang a chain from two points, which is the best way to
evenly distribute the stress on the joint where comb attaches.
Gaudi famously made arches the same way. Hang a chain, trace the shape
and then invert it.

Hi Liz,*Robin Colyer* he/him <https://www.mypronouns.org/home>
One of the theories is that they’re measuring the space, which is very
cool, I think 😊

Morning.
Not sure if chaining is the correct term!
Spurred on by Paul's post about adding a fifth box I had a quick look
The bees are building one comb into the third box so a fourth box isto be nadired later on today.
There were lots of bees in the third box - many of them in long chainsdropping down from the just visible comb and from the bars.
My question is - why are they doing that?
Thanks in advance...
Liz.
