| These spiders resemble the wolf spiders (Lycosidae), but have a different eye pattern. Pisaurids have their eyes arranged in 2 rows, the posterior row slightly recurved, the median eyes in the second row slighly (if any) larger than the others. (Wolf spiders have eyes arranged in 3 rows). |
 This egg sac is about 15mm diameter. |
|
The egg sac is carried by the female under her prosoma, held there by her chelicerae and pedipalps. It is further supported by silk lines to the spinnerets. [1] She carries her egg-sac until near hatching. She then spins a protective web in which her hatchlings live until their first moult. |
 |
| Before the eggs hatch, the female attaches the sac to a plant and then builds a web around it (below). When the eggs inside are hatching, the momma spider opens the cocoon and releases the hatchlings — then stands guard nearby. The hatchlings remain in the web until thier first moult. The Pisaurids forage for their food and build webs only for protecting their young. |
