Like many other venomous creatures, the black widow spider has bright red pattens on it as a warning sign for predators that would attempt to feed on it. The black widow spider is not capable of killing a bird that would eat it, but the digestive sickness that would follow, will be definitely enough to make it avoid attacking the black widow again. Quality photos or drawings as well as proper descriptions of the species are necessary when trying to distinguish between the various spiders that live so very close to us. Homemade traps and low toxicity plant-extract pesticides are often used against the poisonous inhabitants of our houses that can give us some very nasty bites. 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. 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. The unusual fact about these creatures is that they have a very large body and well developed sense organs similar to the insects' antennae. One other peculiarity of the camel spider is that it makes a rattling noise when moving around, which makes it all the more scary at a first glance. Unlike other regular spider species, the camel spider is both carnivorous and omnivorous: it basically feeds on other arthropods, but it is not uncommon for the camel spider to devour larger prey such as lizards. 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. 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.
