Beneath a Martagon Lily leaf, mom guards her egg case. (1x magnification.)

Running crab spiders are hunters, and do not build webs to capture prey. When hunting they do lay a dragline behind them as a sort of security line, not unlike a mountain climber’s belaying rope. As you can see above, the silk is also used to protect the eggs.
