Nephilengys borbonica is a species of spider native to Madagascar and nearby islands (the Mascarene Islands, Comoro Islands and the Seychelles). In Madagascar, this species is commonly found in houses and buildings. In RÃ©union, it can be found in cloud forests up to 4,900 feet. The species name borbonica refers to the island of RÃ©union, which was called Bourbon until 1848.
The adult female grows to 0.6 to 0.95 inches long in Madagascar. The females from other neighboring islands tend to be smaller. The male is smaller at about 0.25 inches long. The abdomen is dark gray to brown or purple. The sternum is red in some female specimens from Madagascar and all female specimens (those that were studied) in the Comoro Islands. The abdomen color can vary between the islands, from white to red.
