The Madeira Cockroach is a large tropical cockroach, mottled brown-and-gray, that is occasionally established in heated buildings in North America. It is commonly kept in laboratory settings as a model organism for neuroscience research due to its accessible nervous system. Unlike pest cockroaches it is not associated with unsanitary conditions.
