Heteropoda venatoria is a species of spider in the family Sparassidae, the huntsman spiders. It is native to the tropical regions of the world, and it is present in some subtropical areas as an introduced species. Its common names include giant crab spider, pantropical huntsman spider or cane spider. [1]
Eusparassus is a genus of huntsman spiders, known as the stone huntsman spiders, [3] ... Females of this species lay their egg sacs inside the retreats. [3] Species
Egg sac of P. castaneus, similar to P. superciliosus Common Rain Spider egg nest Tachypompilus ignitus dragging Palystes prey up a wall. The legs of these arachnids can reach a length of 11 cm, while their bodies alone can reach a length of 4 cm. Interestingly, both sexes of these spiders are roughly the same size. [6]
Females are fertile from May through to September. A few days after mating, the males die. In July, the females enclose the egg-sac into a few leaves stitched together. [6] Cocoons are guarded by females. After about 4 weeks, eggs hatch about 40-50 young spiders. [4]
Palystes spiders are also commonly seen paralysed, being dragged by a large wasp called a pompilid or spider wasp. Sometimes, the wasp is not present. Pompilid wasps only hunt spiders, which they paralyse by stinging them. They then drag the spider back to their nest where they lay an egg on the spider, then seal the spider and the egg in.
Females suspend their egg sacs in their webs; the spherical egg sacs have a tan papery outer layer. [3] Each egg sac contains from 150–200 eggs, with a single female producing 15–20 egg sacs in its lifetime. [citation needed] The spiderlings remain in the mother's web for several days after coming out of the egg sac. [5]
Like other members of the Pisauridae, P. mira carries its eggs along with it in a sac that is secured both by a thread of silk linking it to the spider's spinnerets and by being held by the spider's chelicerae. When the eggs are nearly ready to hatch the mother builds a nursery web within which the egg sac is then hung. After they hatch, and ...
