Signature Spider Facts
- Firstly, the commonly used term Signature Spider remains the common name for any arachnid in the genus Angiope. Currently, scientists recognize 75 members of this impressive genus.
- Secondly, its common name comes from the four unique zigzag patterns individuals create in the center of the web. Scientists named these patterns stabilimentum, and believe they serve several purposes.
- Further, these purposes include attracting insects and warning larger creatures of the presence of the web. That would make sense, since the majority of the web typically remains practically invisible.
- Finally, it has evolved specific behavior patterns. The legs usually get held together in pairs while the spider sits stationary in the web. Therefore, most prey does not recognize the creature as a spider.
Signature Spider Physical Description
Most notably, the various species of Signature Spider exist in a wide range of sizes and appearances. The various species also exhibit sexual dimorphism in the same manner, that being physical size.
Due to this, females typically reach several times the size of the males. Furthermore, females of a few of the largest species attain a leg span of as much as 4 in (10 cm) across. Yet males rarely exceed 1 in (2.5 cm) across.
In addition, the majority of species present basically the same color pattern. This consists of a predominantly yellow body, with black legs. Finally, the eight legs also grow long and powerful, relative to its body size.

Signature Spider Distribution, Habitat, and Ecology
First of all, it must be noted that the remarkable Signature Spider has an extraordinarily wide distribution. That’s because the various species in the genus inhabit every part of the globe, except Antarctica.
Therefore, the differing species understandably thrive in differing habitats. These include jungles in the tropical regions, to forests, gardens, and even private yards, in temperate regions. But, most species occur in temperate and tropical climates.
Also, the majority of the different species of Signature Spider construct the webs roughly 3 ft (1 m) above the ground. Most prefer regions of dense foliage since this also typically means the presence of large numbers of small flying insects.
Though all typically prey on quite small insects, most remain capable of killing an insect twice their own size. Further, a few of the larger species can also deliver a rather painful bite to a human being.
Finally, though, this occurs simply due to the sheer size of the spider. This is true because most have no venom at all. That fact remains consistent even for those few species in the genus that do possess it, however.
That’s because the venom remains essentially harmless to humans, except for those with relevant allergies or health issues. Finally, its toxicity and and effect roughly equals that of the sting of a bee.
