A special feature of the wolf spider is the position of the eyes on the body; the four pairs are arranged in very unique ways, with four small eyes in a bottom row, two large ones placed in the middle and two middle-sized ones on the top row. The specificity of their vision organs is the one that ensures the survival of the species since the wolf spider depends on the eyesight to hunt. When you are able to identify spider species correctly, the risk of getting bitten out of personal negligence is a lot lower; moreover, in case you do get bitten, you can provide valuable information about the species, thus making treatment a lot easier. Many patients are yearly treated for the wrong affection because of the misidentification and misdiagnoses of spider bites. The color variety may be absent, just as the violin marking can be hardly visible. Nevertheless, there is one other element that clearly makes the recognition of the brown recluse spider possible. One identification method used by scientists consists in checking how many pairs of eyes the species has; the brown recluse spider has only three pairs of eyes, unlike most other spiders that have four. Unlike other spider species that have four pairs of eyes, brown recluse spiders have only three: one medianly located and the other two pairs lateral. If you suspect to have been bitten by such a spider, it is good to keep a close watch on how the condition of the affected area evolves. There should be no pain felt at the beginning, as reactions only appear within two or up to eight hours after the bite. Unlike other related species, the hobo spider isn't hairy; though the legs of these creatures are very strong and large, they are also very smooth. 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. 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. Camel spiders are more likely to hunt at night; they are nocturnal creatures that enjoy shady environment even if they mainly live in warm and arid climates.
