About

The brown widow is a shy spider that dwells in dark corners of sheds and gardens. Its egg sacs are covered in stiff, silk spikes that deter predators from eating its young.

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.
