Identification

for American Cockroach

UF calls it the biggest of the common around-the-building cockroaches, averaging about 4 cm (1.5 inches), while Texas A&M gives a range of one and a half to two inches, so plan on roughly 1.5 to 2 inches. Adults are reddish-brown and fully winged (longest in males); the surest field mark is the shield behind the head (the pronotum), edged with a pale tan-to-yellow margin. Wingless nymphs grow wing pads as they molt.
