Females vary from 12-24 mm in length and from nearly white to nearly black in color. Typically in Florida, females have a mostly reddish-brown cephalothorax and legs, with darker femora (Figure 1). The dorsum of the abdomen is gray to brown. The venter of the abdomen has a black triangular mark pointing posteriorly; this mark is surrounded by gray laterally and by white anteriorly and posteriorly (Levi 1970). In life, the anterior lateral corners of the abdomen are sometimes bright yellow; unfortunately, this color fades to gray after lengthy preservation in alcohol. The integument is covered with white setae, especially on the carapace and legs.
Eriophora ravilla inhabits open woodland, ranging from live oak in scrub areas to "hammock".
