Cockroaches may have only migrated to Europe and the U.S. relatively recently, having evolved in India and Myanmar.
The mystery of just how the notorious cockroach became one of the most widespread vermin has been solved by scientists.The origins of the German cockroach —the one usually spotted scuttling through people's kitchens—has remained somewhat of a mystery until now, as they are found in human-made structures around the world—but almost nowhere in the wild.
Cockroaches appear to be closely related to the Asian cockroach, Blattella asahinai Mizukubo, which is native to the Bay of Bengal in Asia and is an invasive species across the southern U.S.'The paradox of a European beginning but Asian phylogenetic affinity is likely due to the almost complete lack of systematic entomological knowledge across the world prior to the 20th century.
