About

The American nursery web spider is a slender, long-legged hunter common in tall grass and shrubs across the eastern United States, catching prey by chasing it down rather than spinning a web. Females spin a silk "nursery" tent to guard their egg sac and newly hatched spiderlings until they can fend for themselves.

Life cycle

  1. 1.
    egg sac
    A silk-wrapped egg sac shelters a clutch of eggs until the young are ready to emerge.
  2. 2.
    juvenile
    A spiderling emerges from the egg sac already in miniature adult form and starts catching prey almost immediately.
  3. 3.
    subadult
    A near-adult arachnid molts through several instars, growing larger and developing mature markings.
  4. 4.
    adult
    Fully grown after its final molt.
