[29]:287–288, Before courtship, a male Portia spins a small web between boughs or twigs, and he hangs under that and ejaculates on to it. Jumping spiders make predatory detours requiring movement away from prey. (1985). Initiating a detour suggests that they may plan ahead on how to reach the prey and also remember the prey's location (13). [2][3]:432 When not joined to another spiders', a P. labiata female's capture web may be suspended from rigid foundations such as boughs and rocks, or from pliant bases such as stems of shrubs. Structure is highly varied but web was basically funnel-like (4). C.Portia coerulea Seedling Plant size G1 Needs a bright location out of direct sunlight. Questions about size constraints should also be taken Data for P. africana (see Fig 2; ‘repeat in experimental’ ? Here, we addressed this using a specialized spider-eating jumping spider, Portia labiata (Salticidae), as the predator, and a jumping spider, Cosmophasis umbratica, as the prey. [2] While most jumping spiders prey mainly on insects and by active hunting, females of Portia also build webs to catch prey directly and sometimes join their own webs on to those of web-based spiders. Cambridge, Massachussetts: MIT Press.16. Figure 11: A detailed description of morphology of a male collected from Malaya (Wanless, 1978). Firstly, Figure 2: Male Portia labiata. [28]:47, P. labiata will sometimes approach a translucent nest containing another spider, and will usually wait facing the prey for up to several hours. Portia fimbriata and Portia orientalis (formerly P. labiata) were presented with a particular problem, how to escape from an island surrounded by water ...

[4]:103-105 The carapaces of females are orange-brown, slightly lighter around the eyes, where there are sooty streaks and sometimes a violet to green sheen in certain lights. fimbriata. This is known as aggressive mimicry. [24]:343, Before being mature enough to mate, females of P. labiata and also P. schultzi mimic adult females to attract males as prey. Males usually wait for 2 to 15 minutes before starting a display, but sometimes a female starts a display first. The jumping spider Portia Labiata can complete detours in which it must move away from a goal (prey) before approaching it. [32]:43 Morphologically, Portia resembled detritus with the markings, tufts of hairs and long legs (18). [3]:437–439 A female P. labiata is effective against insects up to twice P. labiata′s size when the insect is stuck in a non-salticid's web, and against insects not in webs and up to P. labiata′s size, while P. labiata seldom pursues or catches a larger insect in the open. Portia maintained its orientation, then walked to the stabbed prey and fed.

Like most jumping spiders, bold jumpers hunt alone during the day. They stalk insects and usually attacks by lunging and picking up (4).

Portia labiata still exhibited a strong preference toward male C. umbratica over females when UV reflection was masked for both sexes. Google Scholar Wright AH, Wright AA (1957) Handbook of Snakes. [39] This species has been named Sinis fimbriatus (Hasselt, 1882; misidentification), Linus labiatus (Thorell, 1887), Linus dentipalpis (Thorell, 1890), Erasinus dentipalpis (Thorell, 1892), Erasinus labiatus (Simon, 1903) and Portia labiata (Wanless, 1978), and the last name has been used since then. 10. [18][19] A Portia can sense vibrations from surfaces, and use these for mating and for hunting other spiders in total darkness. [3]:439 Males are less efficient in all cases. Portia labiata. Looking more like a flake of bark than a spider, Portia Labiata stops to have a think. These Portia species do not show this behaviour when they receive olfactory signals from members of other Portia species.

Behaviour, 123(1-2), 106-120.14. Signal-generation behavior of Portia labiata, a web-invading araneophagic jumping spider (Salticidae), was investigated in the laboratory. PBS: Public Broadcasting Service. If the Portia waits, the insect becomes less dangerous, but the insect might also escape through the struggles (4). 3 Apr. (species uncertain),[28]:47 and a solitary Odontomachus has been seen attacking a P. Below is a video that shows a Portia's misfortune while trying to attack a St Andrew Cross spider much bigger than it (Video 2).If a large spider is lured by vibrations from P. labiata and approached with threatening speed, P. labiata usually dodge (4). 3 dimensional visualization. [4]:103-105 Males' bodies are 5 to 7.5 millimetres long, [3]:433 with carapaces 2.4 to 3.3 millimetres long. If there is no dead leaf available, the female will make a small horizontal silk platform in the capture web, lay the eggs on it, and then cover the eggs.
