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). 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]
Before the eggs hatch, the female attaches the sac to a
plant and then builds a web around it. 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. |
