The period of time between mating, egg-laying and emergence of spiderlings can vary, and is temperature dependent. [10] They are able to build several egg sacs within one season, [7] and one study found that one female spider produced four egg sacs within four months. S. nobilis can produce large amounts of offspring for a long period after ...
The ‘maternal social’ spider, Coelotes terrestris (Funnel-web spider) uses extended maternal care as a reproductive model for its offspring. Upon laying the egg sac, a C. terrestris mother stands guard and incubates the sac for 3 to 4 weeks. She stays with her young from the time of their emergence until dispersal approximately 5 to 6 weeks ...
The eggs are deposited by the females 5–6 days after copulation. After laying the eggs, females will bind them into a ball with tiny amounts of silk. They then clutch the resulting egg sacs with their mouthparts and carry them around (a behavior common among all cellar spiders). Eggs that somehow fall from the loose bundles do not hatch.
Unlike the more variable developmental stages of T. onustus, the period of the cocoon, or the time between the laying of eggs and emergence of spiderlings, is generally around one month regardless of season. This can be attributed to the insulation provided by the cocoon, making eggs less susceptible to seasonal and/or temperature changes. [8]
Egg laying generally occurs during the months of June and July; during this period, females lay their eggs in small (2 cm) silk tubes and enclose themselves with the eggs, protecting them from predators. Females stay with the eggs and juvenile spiders for about 17 days – until their first complete molt.
The diving bell spider or water spider (Argyroneta aquatica) is the only species of spider known to live almost entirely under water. It is the only member of the genus Argyroneta . [ 6 ] When out of the water, the spider ranges in colour from mid to dark brown, although the hairs on the abdomen give it a dark grey, velvet -like appearance. [ 7 ]
Females lay up to 3,000 eggs in one or more silk ... giving the spider time to flee while the wasps are ... there are very few fossil spiders from this period.
One mated female P. clarus can lay well over 100 eggs per sac in a thick silken cocoon. [4]: 52 An average clutch contains 135 eggs. [5] Most females bear only one clutch of eggs, [11]: 136–137 but some lay more. [1] The females stay with the egg cocoon and usually die a few days after the spiderlings leave the nest. [11]: 136–137
