Despite not using webs for capture, what essential functions does wolf spider silk fulfill?
Answer
Lining burrows, wrapping egg sacs, and creating draglines for descent or leaping.
While wolf spiders are hunters that do not spin capture webs, they utilize silk extensively for various crucial activities related to shelter and reproduction. This includes using silk to line and reinforce their burrows for protection. Furthermore, females meticulously wrap their eggs into protective sacs using silk. When moving or making risky maneuvers, such as descending or leaping during a hunt, they employ a silk dragline as a safety tether.
