Nephila edulis is a species of large spider of the Nephilidae family. It is referred to the common name edible golden silk spider or golden silk orb-weaver.[citation needed] It occurs widely in Australia, where it is found in both tropical and temperate regions, and in parts of New Guinea and New Caledonia.
It has a large body size variability, females can reach a body length of about 23 millimetres, males about 6 mm. The cephalothorax is black with a white pattern on the back, and a yellow underside; the abdomen is grey to brown.
The web is about 1 metre in diameter and protected on one or both sides by a strong "barrier" web. N. edulis breeds from February to May, and produces an average of 380 eggs.
Name
The species name edulis means "edible" in Latin. While it is not entirely clear why this particular species is considered edible, it is known that several Nephila species are considered a delicacy in New Guinea, where they are plucked by the legs from their webs and lightly roasted over an open fire.[2]
The species was first collected and named by Jacques Labillardiere, in Relation du Voyage à la Recherche de la Pérouse (1799),[3] becoming the second Australian spider to described by a European naturalist.[4]
