Tropilaelaps is a genus of parasitic mites in the family Laelapidae.

[1] Their range spans the Philippines, Thailand, Vietnam, India, Sri Lanka, Afghanistan and Pakistan.

T. mercedesae has now established a foothold in Europe with verified reports in the Krasnodar region, Western Russia.

Evidence of tropilaelaps presence in a hive might include deformed wings or legs on honey bees(5).

The University of Maryland Honey Bee Lab is currently monitoring the spread of this parasite outside of its native range and into the United States.
