Banana Spider AKA Golden Silk Orbweaver
The Golden Silk Orbweaver (Nephila clavipes) also known as the Banana Spider is one of the largest non-tarantula spiders in North America. It is the only species of its genus that lives in the western hemisphere and is found in Florida, across the gulf, up to North Carolina, and other southern countries in South America.
Golden Silk Orbweaver webs can measure over 3 feet in diameter and are normally created in forest clearings and can often stretch across trails. The webs trap prey, and their primary diet of this orb weaver consists of a variety of insects.
Females can reach up to an inch to an inch and a half. Their body is orange and brown with black feathery turfs on their legs. Males are distinctly different from females, they are much smaller at around a quarter of an inch in diameter, and their body is brown. Males are seen from July to September waiting for females to mature around August for a chance to mate with them. Males can be seen sitting around the female until she is ready to mate, and multiple males can occupy one web. They will fight each other to have a chance to mate with some even losing legs. Females will produce at least two egg sacks after mating. Each sack can contain hundred of eggs! The sacks can measure about a tenth of an inch and are covered in thick golden silk.
Despite their impressive size and bright color, they are not dangerous to humans. Golden Silk Orbweavers are not venomous and will only bite if they are being held. Banana Spiders can be observed year-round in Florida, though autumn is the best time to view them. If you spot them, remember to keep a safe distance and never intentionally disturb their webs. Spiders of all shapes and sizes play an important ecological role in Florida’s natural and developed areas.
