Re: Changes in swarming dates
Your data is goign to be unreliable if all you do is collect information from those that have seen a change. Sort of like saying 100% of the people polled say they like drink X. But then we didn't poll those that don't like it.
On that note 89510 saw no change regardless of a very mild winter last year. All swarms I know of landed in the typical April to May window. By June bee collection was via trapping or cut outs only.
