The Asian Hornet is said to attack honey bee colonies. In any case, non native species can cause severe disruption to the local ecology.
The late swarm which I caught at the end of July has settled in. It appears to be vigorous and there were many bees flying today. I noticed that they were darker and smaller than I remember from the collection.
It may have been the overcast day which made them look darker. I may be mis-remembering. Seven weeks have passed since I caught the swarm so it's possible that these are new brood.
I seem to have taken a break since the end of August. Today I sorted looked in on the bees.
They won't have been swarming so late in the season so there won't have been much doing (I think) besides a nectar flow from the Ivy. If they fill their stores with Ivy honey it won't be terrible (except that Ivy sets hard).
I have some eke's (low rise boxes usually used to house feeders). I've stapled some hessian into them and filled the cavity with straw. I wanted sawdust but it wasn't available. These are supposed to insulate the roof of each hive.
