Hi Etienne & All
Although I agree that any disturbance of the colony even as minor as walking past or knocking on it with your knuckles will result in increased activity of the cluster, your disturbance of Oct 29 shown on the picture appears to split the cluster which would be a major disturbance. The U of Guelph have done studies, with temperature sensors, of cluster activity, but I’m not sure if they were serious or casual.
