Okay, the longest foraging distance is an interesting point to know,
but the beekeepers is more interested by the average wing distance of
his bees ! That is evident in the question of Nick . This average
(and probably the maximum too) varies from a strain of bee to another.
On this point of view, see after the opinion of Brother Adam (today 95
old) in his book <Breeding the honey bees> (Northern Bee Books ed) :
About the wing-power he said (1982): (p. 59)
" I may quote an example from my own experience. Until 1916 when we had
" the Old-English bee, which shared with the other West European races
" an extraordinary wing-power, we regularly obtained a crop of heather
" honey from our home apiary. The nearest heather was some 3.6 km
" distant at a height of nearly 400 m above sea-level. In spite of this
" distance and a rise of close to 400 m the native bee and her crosses
" in 1915 made an average of 50 kg of heather honey per colony. Since
" then only very seldom and then only when the weather was exceptionally
" good have we had heather honey crops at this home apiary.
So .. seems the N-Z description correct but you could record some
experiences with your own bee lineage to reduce the difference (3-5km).
