The subject portrayed is probably a female as it measured around 21mm in length; males are usually 12 to 15mm long while females can reach 25mm or, rarely, up to 50mm in length.
Adults possess a bright, light green coloring and translucent, shiny elytra. There is a thin yellow margin on the pronotum and the anterior half of the elytra. The face is whitish, the top of the head is brown and the antennae are orangeish. Head made of a labium, labial palps, maxila, maxillary palps and labrum. Abdomen with a yellow margin. Eyes are dark brown, large and compound. Metathorax, prothorax, mesothorax and anal cerci present. Legs are made of a coxa, coxal trochanteral joint, trochanter, femur, femoral-tibial joint, tibia covered in spikes, tibia-tarsal joint, tarsus and claws. Nymphs are wingless and brown in color, and turn to white after molting to the adult phase, slowly transcending to the light green color.
They are native to the neotropics, being found in Mexico, West Indies, USA, Central and South America. They can be found in shrubs, trees, herbaceous plants, piles of leaves, piles of firewood, logs, mulch and leaf litter. They can be rarely found indoors and you can find two occurrences of such a case in this post.
They are nocturnal in activity and, even if rarely found in doors, are attracted to light sources but they will not breed indoors and are of terrestrial ecology.
The females will hatch the ootheca internally and give birth to the nymphs. Nymphs and adults need to be warm and humid for a better development and life quality, respectively, as they are tropical and subtropical in nature. Adults can easily fly if disturbed. They are soft-bodied at all ages.
They do not eat much but will feed on vegetables, fruits and even dog rations, also being detritivores. They are predated by reptiles, ants, mantids, frogs and other insectivores.
The reason I'm not sure this is a Panchlora nivea is due to the distribution status. They share a similar distribution status with other Panchlora such as P. thalassina (Saussure & Zehntner, 1893) (http://cockroach.speciesfile.org/common/basic/Taxa.aspx?TaxonNameID=1173616)#!#, P. carioca (Rocha e Silva, 1959) (#!#http://cockroach.speciesfile.org/common/basic/Taxa.aspx?TaxonNameID=1173568)#!#, P. prasina (Burmeister, 1838) (#!#http://cockroach.speciesfile.org/common/basic/Taxa.aspx?TaxonNameID=1173607) and perhaps more. This means that P. nivea is more of a guess than an assurance, mainly because P. nivea is the most commonly recorded species; by no means this means it is one, even after checking the matching morphology as I do not know the morphology of all Brazilian species. It is, however, definitely a Panchlora sp..
Since this genus is made of wild cockroaches which are usually found in forest-like habitats with trees and shrubs being rarely found indoors, along with their limited diet compared to the domestic cockroach, I know no known cases of disease being passed on by them.
"Panchlora" translates to "all green" and "nivea" translates to "snowy".
''Panchlora nivea'', the Cuban cockroach or green banana cockroach, is a small species of cockroach found in Cuba and the Caribbean, and along the Gulf Coast from Florida to Texas, and has been observed as far north as Charleston, South Carolina. It is found in subtropical or tropical climates.
The females can grow up to 24 mm and the smaller males are 12 to 15 mm long. It is winged and a strong flier, pale green to yellowish green in color, with a yellow line running up the sides... more
