Chemical weapon in spider silk repels ant attack
Researchers have shown for the first time how Golden orb web spiders (Nephila antipodiana) add a chemical to their web silk to repel invading ants. The finding adds chemical defence to the impressive properties of spider silk, already known to be very strong, elastic and adhesive, and may provide new opportunities for pesticide design.
