Ladybirds in winter?

L3 Day 56 Went to a NT garden not far away...Hatchlands. Very cold there -3C and the ice on the water trough was at least a couple of inches thick.
There is a very nice children’s playground area with a nice tree house...it’s actually built round a tree, plus various other things for them to climb in and out of, all made of wood.
Liked the ladybirds high up on a tree!
