question: So how does one differentiate honeydew from nectar?
"Honeydew comes from the back end of an aphid, the front end of which
is sucking sap. Nectar is produced from the nectaries of flowers."
Honeydew is also produced by homopterans other than aphids,
including many species of scale insects. For example, in higher
elevations in California's Central Valley, copious amounts of honeydew
are sometimes produced in the fall months by scale insects on cedar
trees. The ground and all lower vegetation can become coated with a
glaze of honeydew by that exudate.
Those who move colonies into that region before honeydew secretion
begins can get a fair crop of "honey." Although some Europeans relish
honeydew, it is not too good a feed for honey bees, consisting mostly
of glucose. (A rather ancient ABC and XYZ book I have includes the
statement, "Don't feed glucose to bees, glucose is death to bees.")
Moving colonies into an area already glazed over by honeydew,
though, usually results in no crop. The bees just don't seem to catch
on that it is sugar by then.
