The snare made by this spider is very variable. In many instances it is a simple 
circular perpendicular snare of from 5—10 inches in diameter.

The spider sits in the centre on a mass of debris head downwards, though some- 
times il places itself horizontally. However, it often makes the snare with a free arc, 
through which there is a band of grey silk with debris, or with a line of debris across 
perpendicularly or horizontally, in other cases with a leaf on which it sits.
