'Delicate and magical': an artful nest box find
Put up a nest box and you never quite know what will find its way in there.
Pip Piper was cleaning one in his Hailsham garden earlier this month and made an intriguing discovery.
“Other than some of last year’s moss there was also this inside,” he posted on our Nature Table Facebook group.
“It was laying flat on the bottom at the edge and mostly in one piece when I found it. Is this the work of a leafcutter bee?”
Other members of the group quickly confirmed it was.
These ingenious structures are protective homes for developing bees.
In spring and summer, the female bee cuts circular shapes from leaves and petals, and constructs a little chamber with them.
The bee drops pollen and nectar within it and lays a single egg, before sealing it, and building the next chamber on top.
Often these are created within a tube, such as a hollow stem or a hole, and end up as a long, artfully-crafted cylinder.
Nature Table members described the chamber as 'delicate and magical', 'amazing creature craft,' and 'better rolled than some cigars I've seen'.
The bee egg hatches in summer and feeds as a larva on the nectar and pollen that the parent has left them. It then pupates and becomes an adult bee in the autumn.
But instead of leaving the chamber, the adult stays put, hibernating over the winter, and waiting for the warmth of spring before they emerge.
As for these bees, Pip says he has tucked their chamber away again to leave them in peace.
It’s National Nest Box Week, and a good time to make sure nest boxes are cleaned ahead of the breeding season.

Wow, I’ve never consciously seen one of them before but then again, without the knowledge it might just get brushed aside. It’s amazing that these creatures can build structures like this, a hatchery, then a home, brilliant. Nature is amazing!!

Last year I watched a bee flying over to a neighbouring garden and returning to my insect box with a piece of leaf bigger than itself. It spent three days repeating the process and meticulously
wrapping the leaves in a circle around the inside before sealing it up. Such amazing creatures!

Can’t wait to see the adult leaf-cutters (Patchwork) females again on my Weald allotment in Hove. From July onwards on warm dry days, some of the first things I notice are their tiny bums, with their orange pollen brushes, protruding as the forage deep for nectar among their favoured blooms, on my plot Black Knapweed and Bird’s-foot-trefoil.
