David Eyre stated that angry bees are maybe just better robbers, couldn't
agree more, and after their pillaging sessions return home with maybe more
than a stomach full of honey, i.e. varroa mites.
 
All possible, but more likely that his colonies have been invaded by local
collapsing colonies, both feral and the -- look in the brood box every Leap
Year beekeeper, missed it, will have to wait another four years -- managed
one's. I think that's the experience of the UK and before that on the
continent.
 
If there are mites in the area for robbers to collect a few hundred,
collapsing colonies will quickly import many, many thousands.
 
Doesn't alter the fact that angry bees are no good to anyone, well at least
not in a densely populated area such as the UK.
