Panchlora nivea, the Cuban cockroach or green banana cockroach, is a small species of cockroach in the subfamily Panchlorinae. It is found in the subtropical or tropical climates of Cuba, the Caribbean and southern US: along the Gulf Coast from Florida to Texas and has been observed as far north as Moncks Corner, South Carolina. Panchlora nivea got into the US through Caribbean fruit shipments.
The females can grow up to 24 mm and the smaller males are 12 to 15 mm long. They are winged and strong fliers, pale green to yellowish green in colour, with a yellow line running up the sides. The nymphs are brown or black and are burrowers.
The ootheca (egg case) is 3–4 mm (0.12–0.16 in) long, is curved, and has indentations that show where the eggs are located. A study found that they contained 28 to 60 eggs (average 46). The ootheca is carried internally by the female until the eggs hatch. At 24 °C (75 °F) the eggs hatch in about 48 days, after which male nymphs mature in about 144 days, and female nymphs mature in about 181 days.
Panchlora nivea is usually an outdoor species and is rarely found indoors, so is not considered a pest. The adults can often... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Banana Cockroach is recorded against all the insects logged in Braulio Carrillo National Park (18 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
