Brown-banded Cockroach Supella longipalpa

Tiny but unmistakable, the brown-banded cockroach measures just 10-14mm yet is the most famous in its genus. Its two light-colored bands running across the wings and abdomen are its signature look—though the bands can appear broken or irregular. Show some patience and you'll notice striking sexual dimorphism: males are slender with wings fully covering the abdomen, while females are wider with wings that leave the abdomen exposed.
