Spiny-backed orbweaver, Gasteracantha cancriformis, from the Timuacan preserve near Jacksonville, Florida.
A very exciting find from my trip to Florida - a net-casting spider, Deinopsis spinosa. Also known as ogre-faced spiders, the Deinopidae family capture prey by throwing webs onto passing invertebrates, not unlike the weighted nets of gladiatorial retiarii.
Spotted orbweaver, Neoscona sp. (Araneidae) from the Timucuan Preserve in Florida.
