Rock Weavers
Titanoecidae is a family of cribellate spiders comprising five genera and approximately 67 species. Members are primarily dark-colored web-builders that construct woolly, cribellate silk webs. The family occurs across the New World and Eurasia, with several species inhabiting high-altitude mountain environments where they can achieve high local abundance. The family was elevated from Amaurobiidae by Lehtinen in 1967.
