Identification

Adults measure 10–15 mm (~3/8–9/16 in), range from brown to dark brown, and carry two clear parallel bands that run the full length of the pronotum — the plate-like shield just behind the head. Source: https://ask.ifas.ufl.edu/publication/IN128
NC State Extension gives a comparable picture, calling the adult a light caramel-brown with a pair of lengthwise black stripes down the pronotum, while the nymphs are smaller, oval, and a much darker brown to black. Source: https://entomology.ces.ncsu.edu/german-cockroach/
