The female spins a sheet
web supported by a loose tangle of silk. The spider hangs upside down on
the platform when it rests at night. Moulting of juvenile female P. labiata
takes place in the web, after which the spider abandons the web, leaving
the cast skin in it. Eggs are wrapped in a pinkish egg sac which is suspended
in the web and guarded by the mother (by sitting on it) until the 50-70
spiderlings hatch out about 18 days later. Spiderlings are able to spin
webs one to two days after hatching.

labiata are long-legged Jumping Spider, recognised by conspicuous fans
of hairs on the legs, and ornate tufts of hairs on the body, especially
on the abdomen. These features distort the body outline and enhance its
resemblance to a lump of debris, especially when it folds its first three
pairs of legs close to the body in its normal resting position. The camouflage
is further enhanced by behavioural modifications: they walk in a slow and
deliberate manner. Rushing about like other Jumping Spiders would have defeated
the purpose of camouflaging itself as a piece of detritus.
unusual Jumping Spiders of the sub-family Spartaeinae have a different
eye arrangement compared to other Jumping Spiders. Whereas the posterior
median eyes (i.e., the eyes in the second row) of most Jumping Spiders
are tiny, there is a category of Jumping Spiders whose posterior median
eyes are fairly big. These include spiders in the genera Cocalus,
Phaeacius, Portia and Spartaeus.
