Egg Sac

What does an egg sac look like?

Tarantula egg sacs come in two types:

Most New World and Asian tarantulas produce a spherical cocoon which is carried about by the female.  This type looks like a small white ball. 

Most African species (except Hysterocrates and Phoneyusa) produce a fixed egg sac which is incorporated into the retreat’s webbing.  This type looks like a thick, white hammock and is usually sat over by the female (as in photo below).

How long will an egg sac take to ‘hatch’?

Typically between 1 and 4 months.  It depends on the species involved and the temperature at which the egg sac is kept.
