Other insects are equally enthusiastic about lindens, notably aphids and Japanese beetles.

Aphids are inconspicuous and often overlooked except when they deposit honeydew on decks, patios, automobiles and other things beneath the trees.

Japanese beetles are another matter.  Hordes descend in July and forage with such lust that ghost-like canopies of skeletonized leaves are often all that remain in August.

Japanese beetles are relative newcomers in the Twin Cities area.  So far as I know, no one has yet investigated whether or how the beetles’ nearly annual linden defoliation might be affecting the frequency and volume of the trees’ nectar flows.

So will beetle leaf damage reduce the amount of linden nectar available to honeybees and other pollinators?  If so, will the effect on honey production be noticeable?
