In #beetober it will be (hitch)hike.
Surely you saw bumblebees with small brownish “dots” in their hair. You might think that they are varroa but they’re not. Varroa is a parasite which attacks presently only honeybees. Those bumblebee “dots” are mites, too, but they don’t suck their haemolymph or do any harm – in this life stage they are just hitchhiking to the bumblebee nest. Inside a bumblebee colony, they often are harmless or even beneficial, eating debris or hunting for harmful mite species. So, you don’t need to worry about a bumblebee carrying mites on her.
