The males are likely to leave their nest and go hunt somewhere else, while the females will not go far from the web. Their favorite hunting moment is the night, when there are less chances of being disturbed, threatened or exposed to the dangers of the outside world. How can one actually recognize a brown recluse spider? 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. The specificity of the hobo spider is related to the way it weaves its web: the funnel-shaped nest is the perfect structure to wait for prey in. The hobo spider is often found in homes or in their vicinity and though the general reputation of the species is that of high aggressiveness, these creatures are very unlikely to attack a human being. Thus, you may find brown widow spider specimens in a variety of colors from light tan to dark brown; moreover, all sorts of markings decorate their bodies making them all the more unique. There are red, orange, yellow, black and white patterns that the brown widow spider may carry on the abdomen, all of these features misleading any untrained eye. Unlike the general opinion that associates spiders with webs, this is not the case with the huntsman spider: this species goes out to hunt its pray as it doesn't wait for it to get caught in a web. Tree bark, crevices and even garages and sheds are the favorite places where the huntsman spider would make its home. For such cases spider identification is not necessary; but we cannot say the same thing about the widow spiders that require the immediate use of an anti-venom. Therefore, spider identification can be crucial when you need to be able to apply the right treatment without any further delay. Spiders that live outdoors are more difficult to identify due to the large number of species both harmful and venomous.
