The Biotic Associations Of Cockroaches PDF Download

Excerpt from The Biotic Associations of Cockroaches: With 37 Plates This is true of the cockroaches, which now include approximately described species. Conservative estimates based on partially studied museum collections and the percent of new species found in recent acquisitions, particularly from tropical and subtropical coun tries, indicate that at least species remain unnamed. Although the group is well known in general terms to nearly all entomologists, there is an almost complete void of information about all except the few domestic species and, to a progressively diminishing degree, some 400 others. Many details about the lives of even those that share man's habitations are not fully understood. This then is a rough measure of how little is known about cockroaches.
