Phrynarachne sp MEROTAI Hatching
I have been following a young female on a piece of leave for few days. Then on 9-10-2014 it no more at the spot any longer. Phrynarachne sp MEROTAI do not change residing spot often as other spider does. Only disturbing will sue it away. Or it might have been eaten by a bird I feared.
Or perhaps it might hide somewhere else temporary such as from strong sunlight. I search the attaching leaves and to my excitement, it is just a leave above away and in a brand new "home". It has made herself a newly webbed silk camp and hid inside the bag. Its a sign of egg laying and hatching in progress.
This spider species in Borneo is not yet identified
scientifically. I will temporary give it this code for
identification and searching:
MEROTAI because this species was first found in Merotai area.
Phrynarachne sp MEROTAI is one of the few tempted spiders always stay at the very same spot and do not wander around like other species. Like a pat at home that we can see and watch every day. I will follow her hatching process through and all images of her will be labelled "Phrynarachne sp MEROTAI 03OCT14"
Almost all female spiders protect their eggs by making a silk ‘bed’ and then covering them with a silk ’blanket’. She then wraps them in more silk to make the egg sac.
The spider hangs or attached the sac someplace safe and guards it until the babies hatch. When the babies hatch they often stay inside the sac to finish developing.
Some spider mother’s stay until the spider lings leave the sac, others will either leave or die before seeing their babies. For this "Phrynarachne sp MEROTAI 03OCT14" female (image above) what will happen to her? This will be an exciting observation for weeks and months following.
See here for all detail about this spider "Phrynarachne sp MEROTAI 03OCT14".

Species: Phrynarachne sp MEROTAI
Phrynarachne of Borneo
Bird-dung Crab Spider, Phrynarachne sp. (Thomisidae)
|There is a tree in Merotai where a
family of about 10 Phrynarachne sp MEROTAI are residing. This
was discovered in October 2014.
Look similar to Phrynarachne ceylonica (O. P.-Cambridge 1884) Bird-Dung Spider
Commondly called Bird-Dung Spider
because the spider's blobs and warts over the thick and somewhat glazed body surface give the
"wet" and "lumpy" look of a piece of fresh bird excrement.
Classification: Family Thomisidae,
The spider reinforces the simulation of bird-droppings by drawing its legs close to the body and lying motionless on a leaf for long hours.
Bird dung crab spiders under the genus Phrynarachne appear to be one of the rarest group.
Only 30 species are recognized as such spiders in genus Phrynarachne as against 41,253 species of spiders known globally.
The Bird Dropping Crab Spider employs clever mimicry to deceive both its predators and prey.
The coloring of its body, along with a layer of white silk deposited on the leaf, make it appear as an unappealing piece of scat. The odor of the spider, which is also reminiscent of a bird dropping, may serve to attract flies which then become an easy meal.
|The female's blobs and warts over
the thick and glazed body surface give the "wet" and "lumpy"
look of a piece of fresh bird excrement.
Some Phyrnarachne spiders emit a pronounced smell of faeces or urine. The sight and smell of bird-dropping may be a clever device to attract and ambush flies.
The hair grand extract oilly
transperient liquit (see image left) which may be the source of the
pronounced smell of faeces or urine that attract flies.
|This female Phrynarachne sp MEROTAI is 10mm
in body length.
The two pairs of front legs when straight out into straight can reach a span of 20mm from one tip to tip of another leg.
