What the species is and where it came from
Apis cerana japonica is a Japanese subspecies of eastern honeybee, introduced from Korea during the Imjin War—not through natural migration—and endemic to Japan.
How it works, in terms someone would actually use
It defends hives by forming CO₂-rich bee balls that heat to 46 °C, kills hornets with heat and suffocation, and smears plant material at hive entrances when threatened.
What it gets right
It gets thermoregulatory hornet-killing right. It gets pheromone-based orchid deception right. It gets Varroa jacobsoni resistance right.
What it does not
It does not recruit nestmates to propolis sources. It does not offer nectar to orchids it pollinates. It does not migrate naturally—it was introduced artificially during the Imjin War.
What it changed
It changed how we understand honeybee communication: it dances for flowers but not propolis, and performs short waggle dances after hornet scouting—unlike any other known honeybee.
Who it is for, and who it is not
It is for field ecologists, apiculturists managing Varroa, and evolutionary biologists studying chemical mimicry and collective defence. It is not for general beekeepers seeking high-honey-yield stocks or gardeners needing broad-spectrum pollinators.
Is it worth your time
Yes—if you study coevolutionary arms races, pollination deception, or thermoregulatory defence in social insects.
