By the varroa destructor, no less (who said scientific names couldn’t be evocative, eliciting a knowing chuckle or smirk). Varroa destructor is a species of parasitic mite that co-evolved with the Asian honey bee. The story is predictable from there: Asian honey bees can survive with these mites, but other honey bees that have not evolved any resistance, cannot. And because people travel with their bee colonies, providing pollination services, and ship starter packages of bees to people needing new colonies around the world, the mite moved out of the range where the bees could coexist with it, into new ranges where they could not.

First into Europe and Africa, and then in the late 1980’s, into the United States. It is now established everywhere in the world that honey bees are except for Australia, though it keeps trying to make its way there too. Incursions were detected in Australia in 2016, 2019, 2020, and again in 2022, officials working quickly to trace and eradicate it when they happen. The mite cannot live out its reproductive life cycle outside a honey bee colony; it is entirely dependent on bees, but their dependence kills the bees.
