i have a cockroach that sort of resembles an oriental cockroach, but the pattern on its back differs from an oriental cockroach. it is a bit smaller than 1 1/2 inches. I got this cockroach from Ewa Beach, Hawaii.

Harlequin Cockroach

Hi curious,
Hawaii is the home of numerous introduced species that are crowding out the endemic wildlife.  We are posting your image in the hopes that someone will write in with a species identification.  Unless it is a wingless species, it is an immature individual.

A special thanks to Karl who identified this Harlequin Cockroach,
Neostylopyga rhombifolia, a Southeast Asian species that has become established elsewhere in the world, including Hawaii.  For more information read Karl’s comment and check out this website:  http://www.gotroaches.com/blog/2006/05/25/harlequin-roach-neostylopyga-rhombifolia/

    This appears to be a Harlequin Cockroach, Neostylopyga rhombifolia (Blattodea: Blattidae). They are native to southeast Asia but have become established in northern Australia, Mexico, Arizona, and they have been reported from Hawaii. They are a flightless, egg-laying cockroach. Regards.
