       Red Widow Spiders are unique spiders from a small range in Florida, USA. They are only found in three scrub palmetto habitats, and due to development and destruction of these habitats, Red Widow Spiders are listed as a species of "special concern". Definitely the rarest widow spider in the United States, and the most colorful, a Red Widow Spider is a treat in any collection. The unique habitat in which it is found has 200' of sandy soil that allows for good drainage and the scrub palmettos are very leathery and able to re-stand drought conditions. Stagnant, high humidity will kill them easily. Red Widow Spiders should only be kept by advanced hobbyists, scientists, and educational professionals due to their dangerous venom. This species is one of the world's most colorful true spiders and makes an excellent display arachnid. It is very important to simulate their unique habitat and climatic conditions in order to successfully keep them. Buying only captive-born spiderlings/juveniles is highly encouraged to keep from over-collecting this rare species. Spiderlings grow very quick. Feeding them wingless fruit flies and true "pin-head" crickets twice a week will ensure you get an adult in as little as 3 to 4 months. As the tarantula hobby expands, more keepers are recognizing true spiders such as the Red Widow Spider as great display animals. A Red Widow Spider is a rare showcase spider for a deserving keeper, and should be cherished by anyone who has one.
