Anelosimus eximius: The Social Spider
 |
| Anelosimus eximius species spider |
The Anelosimus eximius is a social spider which is found in the Neotropical region which is situated in the Central and South America.
These spiders are found in the lowland rainforest of the interior forest floor and forest edge. Their web colonies are found in cleared areas of forest or around the tree falls. The webs can be found as low as a meter off the ground to 20 meters.
Anelosimus eximius is species of thousands spiders that form a well-organized society that fulfills their needs, hunting in loneliness, and know as lone hunters.
Anelosimus eximius is known as a social spider species because they help each other such as babysitting and share the prey that they captured from their large web and because of their large web they can capture a large amount of prey than a single spider. The Anelosimus eximius colonies containing more than 9,000 spiders.
Anelosimus eximius spiders are one of those who live together, building a large web that can cover the whole tree and sharing the food that they get from their large web.

If these spider's colony grew larger, they are not caught more food but they are actually caught less food for each spider than smaller colonies. This is because as the number of spiders in the colony grows, the wideness of the webs they construct also increases but the surface area to volume ratio declines. The area of the web is the important factor determinant of numbers of insects or prey caught, so bigger colonies catch proportionally fewer food items.
The estimates of the prey biomass – the dry weight of prey caught, the larger webs spun by bigger colonies that they are able to capture larger prey items. The Larger portion sizes compensated for the falling number of prey, at least, up to a certain point.
The spider colonies break up at a certain size with the occupants and form new colonies. Also, the size of the spider's colonies are larger than the 9000 spiders, below this size of colonies the occupants are better than those who are starting a new, much smaller colony.
These Anelosimus eximius is a social spider consists of thousands of spiders.
These social spiders perform many tasks in the colony that other normal spiders do not such as the web repairing and construction, child care, defense from other insects and trap together the prey when it get stuck in their web. Also, the spiders share the food when it captured in the web. By performing these tasks the Anelosimus eximius species become more efficient in the idea of maintaining their colony a successful spider colony.

The Anelosimus eximius spiders are permanent living spiders, the emigration is very rare. These spiders are only emigrate when these spider's web or nests are in the roadside because the cars or other vehicles can stick and damage their webs and the weather can cause their web damaged that's why they emigrate to the forest from the roadside.
Seeing these spider colonies is nothing less than a horrible nightmare, right?
