It is 2.5-2.8 cm in length and brown or dark brown in color. The head and tergum are dark brown. The eyes on the sides are orange or red. The patterns on the abdomen are variable with a sharp spike on each side of the reversed triangular abdomen, giving it its Chinese name “Triangular Ghost Spider.” It is large in size. Females are often seen in forests, constructing webs during the night with a wide surface. During the day, it stays amongst higher branches and leaves. When threatened, it curls up its body but does not run away. Males are only 0.3-0.4 cm in length and are rarely seen. (Photo courtesy of Peng Zhen-ru)
