About Ariadna bicolor (Hentz, 1842)
Ariadna bicolor is a tube-dwelling spider species found in North America. Its cephalothorax and legs are yellowish-brown, and its abdomen is purplish-brown. John Henry Comstock noted that the species has remarkable habitats. After collecting the spiders from Ithaca, Comstock created a man-made habitat made of nailed-together blocks, each with a hole, and the spiders used this structure as a nest. In an experiment testing how quickly different spider species respond to odors, Ariadna bicolor reacted slowly. When outside of their tubes, the spiders took an average of 63 seconds to respond to five tested oils. When inside their tubes, they did not respond to the odors at all.
