Pisaurina sp.
Family Pisauridae - Nursery Web and Fishing Spiders.
 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 slightly (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
& pedipalps. Before the eggs
hatch, the female attaches the sac to a plant and then builds a web
around it -- and stands guard nearby. The Pisaurids forage for their
food and build webs only for protecting their young. Some spiders in
this family, particularly fishing spiders in the genus
Dolomedes, are quite large and may have a leg spread of 75 mm
or more. The Dolomedes spiders live near water; they walk on the
surface of water and dive underneath it to feed on aquatic insects
and even small fish. Although nursery-web and fishing spiders are big enough to give a painful bite, they are not considered dangerous.
Many people (including me), are confused by the 5 similar
looking spiders - the harmless Huntsman, Wolf Spider, Southern
House Spider (Kukulcania), Fishing Spider and Brown
Recluse which of course is not harmless.
