In some parts of the world it is mistaken for the brown recluse spider that is highly venomous, but for the knowledgeable eye the absence of the violin shape of the brown recluse species speaks for itself. The largest wolf spider will not be more than two inches in length, but on a common basis their size is variable and lower. Yet, we should nevertheless mention the fact that research on none of these treatments has been conclusive enough to be established as a general remedy for the brown recluse spider bites. In the majority of cases the wound is likely to heal without any medical intervention whatsoever, however, the exception appears in the cases when the venom spreads in a blood vessel. 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. Though the generic name of the funnel web spider is used most of the time, it includes no less than thirty-six species that live both on land and in trees. The favorite habitat of the funnel web spider consists of the moist area under rocks, crevices, rotten trees, holes and tree bark. For the funnel web spider varieties that live in gardens, shrubs are the perfect place to make their nests. The favorite habitat of the brown widow spider includes well protected locations in homes and other man-made structures. You may even find brown widow nests in buckets, mail boxes, entry corners, closets, garages and even in vegetation like shrubs and tree branches. Most bites occur when one accidentally stick their hands into such secluded areas and corners or when the spider gets pressed against the skin. The female black widow spider is more venomous than the male, and it is she the biggest threat to predators. Nevertheless, the red color helps the males too in order to send the same threatening message as the female. While the males move freely in their habitat, the females usually spend their entire lives in just one place, as they very seldom leave their nests.
