Worldwide, except Australia, parts of Africa, and the Antarctic.
Feeds on fat of honey bees through external digestion. Previously thought to feed on the hemolymph.(1)
Introduced throughout the world (except Australia) from its original place in Southeast Asia and its original host Apis cerana. It arrived in the US in the 1980s and had a profound impact on beehives.
At first, there was no certainty whether the introduced species was this or the closely related Varroa jacobsoni or both. Now we know that it is the only species in the US.
In addition to feeding on honey bees, it transmits several viruses to them.
