Identifing a Spider Without any exaggeration, when you know how to identify spider varieties, you could actually be one step closer to saving your skin . Anyone who can recognize spider species, will be able to avoid getting exposed to their bites. The easiest way to tell spiders apart is by comparing them with pictures from albums and learning the features specific to each species or variety. 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. The female black widow spider is more venomous than the male, and it is she the biggest threat to predators. As it seldom happens for a person to suffer from a brown recluse spider bite, many doctors have difficulties in diagnosing certain symptoms that accompany it, very often such a bite can be even taken for a staphylococcus skin infection that is very similar in manifestation and symptoms. The result of such a bite is known as loxoscelism, and it may appear in cutaneous and system manifestations. The most common way to perform the identification at a very amateurish level is to actually compare a specimen with a picture or a drawing and see whether there is a match. The important thing about spider identification is to actually be able to tell the poisonous spiders from the non-poisonous ones. Without being lethal for a human being, poisonous spiders can cause very advanced tissue damage known as necrosis. There is a whole range of symptoms, one nastier than the other that accompany the bite of a dangerous spider: digestive troubles such as nausea and vomiting, headaches and fever, not to mention the local discomfort manifested as pain and itchiness. Unlike most other spiders that grow in our homes, the brown recluse spider does not weave a web, but creates an apparently disordered thread shelter. This species likes to live undisturbed in quiet places like the cellar, the garage, sheds and other locations that are neither too humid nor too bright.
