After a 49-million-year hiatus, a cockroach reappears in North America
Date:1/5/2014

The cockroach in the genus Ectobius is a major textbook example of an invasive organism, and it is the most common cockroach inhabiting a large region from northernmost Europe to southernmost Africa.

Ectobius has a long fossil history in Europe, occurring in Baltic amber that is about 44 million years old, and its lineage was believed to have been exclusively from the Old World. However, a shocking new discovery has uprooted that view. In fact, it now appears that Ectobius may have originated in the New World.

Four ancient Ectobius species were recently discovered in the 49-million-year-old Green River Formation near Rifle, Colorado in deposits that are about five million years older than the Baltic amber. However, these cockroaches soon became extinct in North America. The cause for the extinction of Ectobius in North America in the dim past is unknown, but it evidently survived in the Old World, and western Europe in particular.

"About 65 years ago, several entomologists in the northeastern United States noted that four species of Ectobius were present in North America," said corresponding author Dr. Conrad Labandeira. "It was always assumed that these four newcomers were the first Ectobius species to have ever lived in North America. But the discovery in Colorado proves that their relatives were here nearly 50 million years ago."

In many ways the history of Ectobius mirrors that of the biogeographic history of the horse. Horses occurred in the New World and became extinct during the late Pleistocene ecological crisis. Horses, attached to human habitation, were subsequently introduced to North America by early Spanish explorers about 11,000 years after their demise.

The newly discovered species of Ectobius, specifically Ectobius kohlsi, are described in the January 2014 issue of Annals of the Entomological Society of America (DOI: '/>"/>
