A very common species, the wolf spider is the shy inhabitant of corners, basements and garages around our houses. Unlike most of its brothers, the wolf spider prefers to remain on the ground where it hunts at night; there is no web and no sign that would let you know where you'll find a specimen since the wolf spider desperately tries to stay out of the humans' way. 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. Typically hairy, the wolf spider can be brown or gray with all sorts of markings and lines on the back and the abdomen. The special thing about these creatures is the way the females carry the egg sacs with them, and once the eggs hatch, the siblings remain attached to their mothers' back until they are large enough to detach and start a life on their own. Without being venomous, the wolf spider bite can cause a bit of trouble for more sensitive people.
A special feature of the wolf spider is the position of the eyes on the body; the four pairs are arranged in very unique ways, with four small eyes in a bottom row, two large ones placed in the middle and two middle-sized ones on the top row. The specificity of their vision organs is the one that ensures the survival of the species since the wolf spider depends on the eyesight to hunt. Furthermore, as they spend most of their time at ground level, these creature also have a very well-developed sense of touch.
The wolf spider is not an aggressive species, though it may bite if provoked or threatened. Their bite is not very serious, there will be mild and bearable pain and itching, and local swelling occasionally. Though some of the wolf spider varieties like the Australian and the South American ones were thought to create necroses, recent studies have proved this to be a false myth. As a general rule, the bite of the wolf spider is harmless and far from causing extensive tissue damage or loss, yet, individual reactions to the bite are the ones that often show otherwise.
