Although arachnid sociality at all levels of complexity is uncommon, sociality has been applied to describe behaviors ranging from transient early parental care (Laniatores opilionids: Machado & Raimundo 2001; Machado 2002; Uropygids: Schmidt 2003), to "subsocial" mother-offspring-sibling associations that last for brief periods (spiders: Kim 2000; Schneider 1995; scorpions: Polis & Lourenco 1986), "subsocial" associations that last until sexual maturity (spider mites: Saito 1997; Mori & Saito 2005; amblypygids: this manuscript), to the complex multiple adult societies of the most social of the colonial and cooperative spiders (reviews in Buskirk 1981; Aviles 1997; Whitehouse & Lubin 2005) (see Tables 1-3 for details).
