Linyphiidae (money spiders; order Araneae, suborder Araneomorphae) Family of small, uniformly black or brown spiders which construct sheet webs among vegetation. The webs do not have a retreat, as do those constructed by the Agelenidae; the adult spider hangs on the under-side of the web and runs over it to catch prey. The chelicerae have many teeth, and the legs bear many strong setae. The members of this large family are among the commonest and most abundant species in the northern hemisphere (40% of the British spider fauna belonging to the family). Many species travel long distances by ‘ballooning’ on long threads of silk.
