Chelicerae (fangs) fused at base, cheliceral claw short and opposed (closes to/opposite) by a short toothlike projection of basal segment. Usually with 8 eyes, some species with 6, usually with 2 widely spaced groups of 3 closely-spaced eyes each and 2 eyes in between. Color usually pale yellowish to light brown or gray. RECOGNITIONĪdult body length ranges from about 1/16-5/16" (2-8 mm) cephalothorax and abdomen connected by tiny waist (pedicel) but appearing as small body with very long, thin legs. About 20 species are found in the United States and Canada. Cellar spiders are nuisance pests, probably more because of their webs than the spider itself. The common name cellar comes from these spiders being frequently found in dark and damp places such as cellars, basements, and crawl spaces, and that of daddylonglegs from their very long, thin legs which give them an appearance somewhat similar to harvestmen/daddylonglegs (order Opiliones, family Phalangiidae see similar groups below). ![]() The Daddylonglegs Spider Common Name: Cellar or Daddylonglegs Spiders Scientific Name: Various Class/Order/Family: Arachnida/Araneae/Phoicidae Metamorphosis: Simple INTRODUCTION
