The egg sacs differ fairly widely among the various genera. Males of Heteropoda venatoria, one of the huntsman spiders that seems to easily find its way around the world, have recently been found to deliberately make a substrate-borne sound when they detect a chemical (pheromone) left by a nearby female of their species. Dozens of the social huntsman species, Delena cancerides, can be seen sitting together under bark on dead trees and stumps (notably wattles) but they can also be found on the ground under rocks and bark slabs. More than a thousand Sparassidae species occur in most warm temperate to tropical regions of the world, including much of Australasia, Africa, Asia, the Mediterranean Basin, and the Americas.[4].

Most of the sound emitted is produced by strong vibrations of the abdomen. In some cases (Isopeda), the female may moisten and tear the egg sac open, helping her spiderlings to emerge. Discover more about spider survival. The characteristic frequency of vibration and the pattern of bursts of sound identify them to females of their species, who will approach if they are interested in mating.
