Wolf spider
Wolf spiders are members of the family Lycosidae, from the Ancient Greek word "λύκος"
meaning "wolf". They are robust and agile hunters with excellent eyesight. They live mostly in
solitude and hunt alone, and do not spin webs. Some are opportunistic hunters pouncing upon
prey as they find it or even chasing it over short distances. Some wait for passing prey in or near
the mouth of a burrow.
Wolf spiders are unique in the way that they carry their eggs. The egg sac, a round, silken globe,
is attached to the spinnerets at the end of the abdomen, allowing the spider to carry her unborn
young with her. The abdomen must be held in a raised position to keep the egg case from
dragging on the ground. However, despite this handicap, they are still capable of hunting.
Another aspect unique to wolf spiders is their method of care of young. Immediately after the
spiderlings emerge from their protective silken case, they clamber up their mother's legs and
crowd onto the dorsal side of her abdomen. The mother carries the spiderlings for several weeks
before they are large enough to disperse and fend for themselves. No other spiders are currently
known to carry their young on their backs for any period of time.
Neoscona nautica
Neoscona nautica, the brown sailor spider, is a species of orb weaver in the family Araneidae. It
is found in Asia and Pacific islands, has been introduced into both Americas, and Sudan.
Nephila pilipes
Nephila pilipes (northern golden orb weaver or giant golden orb weaver)[2] is a species
of golden orb-web spider. It can be found
in Japan, China, Vietnam, Cambodia, Taiwan, Malaysia, Singapore, Myanmar, Indonesia, Thaila
nd, Laos, Philippines, Sri Lanka, India, Nepal, Papua New Guinea, and Australia. It is commonly
found in primary and secondary forests and gardens. Females are large and grow to a body size
of 30–50 mm (overall size up to 20 cm), with males growing to 5–6 mm. It is one of the largest
of the orb-weaving spiders apart from the recently discovered Nephila komaci, and one of the
biggest spiders in the world.
The Nephila pilipes golden web is vertical with a fine irregular mesh and not symmetrical, with
the hub usually nearer the top.[2] Rather than egg sacs being hung in the web, a pit is dug which
is then covered with plant debris or soil.
The first, second, and fourth pairs of legs of juvenile females have dense hairy brushes, but these
brushes disappear as the spider matures.
Neoscona
Neoscona, known as spotted orb-weavers and barn spiders,[7] is a genus of orb-weaver
spiders(Araneidae) first described by Eugène Simon in 1895 to separate these from other
araneids in the now obsolete genus Epeira.[8] They have a mostly pantropical distribution and
one species, Neoscona adianta, has a palearctic distribution.[2] As of April 2019 there are eight
species that can be found in the United States and Canada
The name was derived from the Greek νέω, meaning "spin", and σχοῐνος, meaning "reed".[8]
These spiders can be difficult to distinguish from species of Araneus without close examination
of the carapace. Neoscona have a characteristic dorsal groove on the carapace that are parallel
with the long axis of the body. The dorsal grooves of Araneus are transverse or angular, though
they are sometimes so small that they appear as dimples on the dorsalsurface
Nephila antipodiana
Nephila antipodiana, also known as the batik golden web spider, is a species of golden orb-web
spiderdiscovered in 1841 by Charles Athanase Walckenaer. The species is found throughout
Australia, China, Indonesia, the Philippines, and Thailand. The spider's silk contains
a pyrrolidinealkaloid which serves as a chemical repellent to keep ants away from the spider's
web.
Nephilengys malabarensis
Nephilengys malabarensis is a araneid spider.
Females reach a body length of about 15 millimetres (0.59 in). The legs and palp are annulated
yellow and black. Male body size less than 5 millimetres (0.20 in), with mostly grey-black legs.
N. malabarensis is being preyed upon by the spider-eating jumping spider Portia.
