When you see a brown recluse spider for the first time it is impossible not to notice how much it resembles a violin; it is actually known as the fiddle-back spider or the violin spider for the color pattern it has on the back and bottom areas. Though the color specific to the species is brown, there are yellow and black varieties too, nevertheless, these color patterns are not a general characteristic of the brown recluse spider. In North America for instance, poisonous spider identification is a thumb rule for anyone living close to such creatures; there are not too many species of the kind, hence, once you learn how to set them apart you can relax and feel a lot safer. House species are the first to require proper spider identification since they are the first we come into contact with, and, on certain occasions, it is pretty difficulty to tell them apart. The female funnel web spider lives very isolated, it remains in the burrow for almost its entire life; males are the ones that go out to hunt and find mates particularly in summer and autumn months. The number of reported bites is the highest during the mating season when the funnel web spider males enter in houses and garages through small gaps in the doors and window sills. 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. The bite of the brown recluse spiders is likely to cause a whole range of symptoms at the skin level known as loxocelism, and the greatest risk they involve is that of necrosis. Most bites are not only minor but also extremely rare; brown recluse spiders do not attack unless they feel threatened. As their very name suggests they enjoy very retreated corners where they are not bothered by light or intruders: cellars, garages, hallways or any other dark house area. Despite their incredible diversity, all spiders create silk and design complex webs in which they catch their prey, nevertheless, silk is also great for climbing and laying eggs. All spiders depend on their venom for survival: venom is the way to hunt and defend themselves, but from the many thousands species only about two hundred actually represent a threat for human health.
