- Bee -
The bee, Apis dorsata, it is also known as the giant rock bee. It lives in southern and southeastern Asia, mainly in forested areas like the Terai of Nepal. It measures around 17–20 millimeters (0.7–0.8 in) long.
These social bees are known for their aggressive defense strategies and vicious behavior when disturbed. Indigenous peoples have traditionally used this species as a source of honey and beeswax, a practice known as honey hunting.
Each colony consists of a single vertical comb (alot of times are more than 5 feets in width) suspended from above, and the comb is typically covered by a dense mass of bees in several layers.
If they are disturbed, they will adopt a defensive behavior known as defense waving. Bees in the outer layer thrust their abdomens ninety degrees in an upward direction and shake them in a synchronous way. This may be accompanied by stroking of the wings. The signal is transmitted to nearby working bees, that will also adopt the posture, thus creating a visible — and audible — “ripple” effect across the face of the comb, in an almost identical manner to an audience wave at a crowded stadium. It’s a warning sign!
