Without detailed analysis, a correct identification cannot be performed, and it is usually for the professionals to succeed in such daring attempts. The mating period of trapdoor spiders coincides with the wet season when the males get out searching for a mate. Like with other spider species, the female sometimes eats the male, but the latter often escapes being eaten and manages to mate with several females before dying. The surface of the sac is full of pointed projections that make it resemble to a fluffy little ball. In case you notice such a white globe sticking out from a hidden corner, then you can be sure you've come across a brown widow spider nest. Both spiders and egg sacs can be nicely removed with a vacuum cleaner, thus eliminating the risk of direct contact. The easy way to distinguish between males and females is not just body size, but also the length of the articulated feet. One other peculiarity of the camel spiders consists in the presence of several pairs of eyes grouped on various body parts. Thus, they may look more like spiders, but the visual accuracy is considered superior by many researchers. Poisonous Spiders Many people have a phobia when it comes to spiders; hairy legs, devious traps, innocent victims : this is the picture that they usually imagine. This unjust pattern is not justified since even the most poisonous spiders will not attack a human unless they felt threatened. All spiders need to inject venom in order to survive, it is in the nature of their species and one of the life mechanisms they have been endowed with; what really differs from one species to another and gives rise to the classification into poisonous and non-poisonous is the amount of venom and its toxicity. The next thirty six hours are crucial for the evolution of the condition, since it is now that a deterioration or an improvement may occur; generally speaking, the ulcer and the necrosis will only appear within a few days if the health status does not improve. Once the venom has got into the system, there is a whole range of symptoms that accompany the brown recluse spider bite: vomiting, nausea, fever and muscular or joint pain have been among the most frequently reported. The life extent of the hobo spider is pretty reduced, but though this species lives for a short period of time, their existence is pretty intense. Every year around August and September the hobo spider males are incredibly active, and it is during this time of the year that most bites are reported. The shape of the web woven by the hobo spider is truly unique, it consists of a very dense silk sheet which is usually curved upwards so that insects that come from above the structure may fall into it.
