Cuban Cockroach pictures (Panchlora nivea), also known as "Green Banana Cockroaches" because they were found on bananas imported from Cuba.
Cuban Cockroaches are native to Cuba, the Bahamas, Central America, and Mexico. They were introduced to the US in the mid 1900's and are now found in warmer climates from Florida to Texas. Cuban cockroaches are thriving in other places, but typically do not disturb native plants and animals.
When they're young, they're little and brown.
