Blattella asahinai
Asian cockroach
Blattella asahinai, the Asian cockroach, is a small peridomestic cockroach species first described in 1981 from Okinawa, Japan. It is nearly morphologically identical to the German cockroach (B. germanica) but occupies distinct ecological niches, preferring outdoor habitats with leaf litter and vegetation. The species is a strong flier attracted to light, contrasting with its flight-avoidant relative. Since its introduction to Florida in 1986, it has spread throughout the southeastern United States, where it can reach extremely high population densities in suitable habitats.
