The female will lay several hundred eggs in a silk sac, about 10mm across, which they carry under their bodies for around three weeks. During this time she will periodically dip the sac into water to prevent the eggs from drying out. She will also locate a suitable nest site amongst the emergent vegetation, this will usually be between 10 and 100 cm above the water. Shortly prior to hatching she will construct a tent-like nursery web within which she can guard the young until they disperse into the surroundings, usually five to nine days after hatching.
