Physical Description & Identification


Size: Their body is 2 to 10 mm (0.08 to 0.39 inches) long, while their legs can have a length of approximately 50 mm (1.97 inches).

Color: Spiders of this family have a yellow or pale tan body with gray or chevron markings in the middle.

Other characteristics: Thin and fragile, the species possess cylindrical abdomens, with short fangs.


Females produce approximately three sacs in their lifetime, with each of them having about 10 to 60 eggs.


They resemble tiny spiders and crawl to their mother’s body after hatching.

The Web

They make irregularly shaped, messy, non-sticky webs in dark and damp areas. Since the webs lack adhesive qualities, these spiders mostly rely on the irregular pattern for trapping prey.

Are the Species of the Cellar Spider Family Poisonous and Do they Bite

Did You Know

  • They are known as daddy-long-legs, a name used for other species like Pholcus phalangioides (or long-bodied cellar spider). Other members of the arthropod group like the harvestmen that belong to the category of arachnids but are not spiders.
  • Species of this family are referred to as “vibrating spiders” as some of them may respond with rapid vibrations when their web is even slightly touched. This is perhaps their way of protecting themselves from danger as the movement could make it difficult for the predator to locate the spider.
  • Their gait is an alternating tetrapod one where they move the first right leg followed the second left one and the third right limb.
