All:

I'm going to be hard to convince on this one.  We've had up to 50 hives
fitted with counters that keep track of EVERY bee that comes and
goes.  We've run these counters for 10 years, in many parts of the U.S. -
east coast, southeast, southwest, northern tier states.  The counters are
ON 24/7.  We get a few bees milling in and out during the DARK hours (we
run weather stations and light sensors concurrently).  Sometimes we see a
flurry of activity JUST before full dark.  But never have we found any
significant foraging at night.
