I noticed the use of male bee instead of drone. English has been my second language for a long time, and only recently did I learn that mechanical drones get their names from that. Do you native speakers use male bee more often than drone?
Drone is the name for the male of the honey bee. This is a close relative, but different kind of animal. The animals sleeping in flowers aren't necessarily male.
Sometimes yes, but especially children often don't know the word so when you use it you often have to explain. Beekeepers do tend to say "drone" in my experience (Source: my father kept bees for a while).
In a normal conversation you would just say bee. Male bee and drone are not too common unless you are talking to a bee keeper or expert. The article is probably using male bee to clarify that drones are all male.
This comment is in a dire need of citation. Let me provide it:
Why We Sleep: Unlocking the Power of Sleep and Dreams by Matthew Walker.
The book states that every living organism on earth so far tested has shown signs of sleep or sleep like behaviour (like not moving for periods of time, relaxed state, etc).
Some people cannot or will not see the simple and honest beauty of something like a bumblebee in a flower, and would rather trample them all in the name of industry.
