At last check, there were an estimated 115,000 to 125,000 beekeepers in the US, most of whom were hobbyists. In particular, ownership of honeybee colonies appears to have risen in recent years, with amateur apiarists wanting to help preserve these powerful pollinators in addition to generating their own source of sweet, sticky goodness. But caring for honeybees can be tricky. Colonies follow very specific activity patterns throughout the year; they should be very busy in warmer months and idle when it's cold. So, they need to be checked regularly for health and productivity. Beekeepers can inspect hives by opening them, but this invasive process risks harm to the colony, particularly the all-important queen.
