Before Varroa destructor got this rather menacing name, it was called Varroa jacobsoni after its collector by the Dutch zoologist Anthonie Cornelis Oudemans.

Java in turn happens to be the place where Varroa jacobsoni was first found by the collector E.

Oudemans concluded that the sightings might refer to a previously unknown large seal, which he dubbed Megophias megophias. His work was later considered to be one of the first in cryptozoology.
