As do other funnel weaver spiders these are hunting spiders that are quite agile and run well. However, they spin large webs over surfaces, particularly on low, dense plants outdoors, and reside within a narrow tube or “funnel” below that webbing. When an insect is detected on the webbing above it is quickly grabbed, subdued, and eaten. These spiders may often create their webs indoors where clutter is found in undisturbed places. Indoors they may live up to 2 years but outdoors will die once cold weather occurs in the winter. In the fall the female creates her egg sac, containing about 50 eggs, and attaches it within the funnel in her web. These eggs overwinter and new nymphs emerge in the early spring. The spiders are very shy and will avoid all contact if possible. Their bite is said to be painless and of no consequence to humans.
Indoors the spiders and their webs may be removed with a vacuum cleaner. When the webs are found on plants outdoors the ideal response is to leave them alone and to enjoy them. They are feeding on other unwanted insects and are highly beneficial. If necessary due to customer pressure the plants may be treated with a labeled insecticide for short term relief from the spiders and the web removed with a stream of water.
