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. In terms of toxicity, the black widow spider has one of the most potent venoms in the animal world: it is actually fifteen times stronger than that of the rattlesnake for instance. Lots of efforts have been made so far in the direction of creating an antidote for spider bites in general, but, unfortunately, scientists have not been successful just yet. The only way to avoid the unpleasantness of the situation is prevention: cleaning the house regularly and eliminating spider webs from very hidden corners could prove essential. The favorite pray of trapdoor spiders includes grasshoppers, moths, crickets, but they don't back off when it comes to having small birds and scorpions for their meals too. The size of trapdoor spiders is not larger than three centimeters for the body, with the females clearly dominating the males in this respect. 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 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. The color variety may be absent, just as the violin marking can be hardly visible. Nevertheless, there is one other element that clearly makes the recognition of the brown recluse spider possible. It is not unusual to misdiagnose various skin infections as brown recluse spider bites, since the symptoms are very often miscellaneous. Statistics show that 80% of the brown recluse spider bites are misdiagnosed. A test has been created to identify the wound and the venom type, but the practice is not part of the medical routine yet.
