The bite of the brown widow spider is pretty painful, causing a lot of trouble to the victim, yet, it is not even by far as serious or as toxic as that of the black widow. There is a paradox related to the qualities of the brown widow spider venom: when compared to that of the black widow it is twice as potent. The camel spider is even falsely called a spider, since the species is cataloged under a different name in the zoological categories. More likel scorpions, the camel spider is part of an arachnid order known as the solifugae; they live in arid hot climates, including deserts from both the Northern and the Southern hemispheres. 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. The preference for shade is the actual explanation of the impression lots of people got that the spiders may be attacking them. The human body represents a corner of shade, which will surely attract the spiders; this is the only explanation for the fact that these creatures get closer to humans in a variety of circumstances. Hobo Spiders Living in both Europe and North America, hobo spiders are a species that prefers moderate climates, making their nests both in houses and outside, in gardens, hedges, fields and pastures. In the United States, hobo spiders are considered a real danger since their bite can cause severe necrosis; nevertheless, the reported cases are pretty rare, as the most likely symptoms to appear include local pain, itching and swelling of the bitten area. Many patients are yearly treated for the wrong affection because of the misidentification and misdiagnoses of spider bites. Since necrosis can appear in the worst of cases, doctors can sometimes take it for other skin problems caused by staphylococci or fungi. Hence, the ability to correctly identify spider bites is vital for the right treatment of necrosis. Mating is dangerous for the funnel web spider as the females are very aggressive, this is why the male funnel web spiders have to hold them with the spurs on the second legs. For the protection of its eggs the female funnel web spider will bite fiercely, hence this is the period during which the chances of getting bitten are the highest.
