The hourglass mark specific to all widow spiders colored in yellow or orange remains a distinguishable characteristic on the bottom of the abdomen. The bite of the brown widow spider is pretty painful, causing a lot of trouble to the victim, yet, it is not even by far as serious or as toxic as that of the black widow. Moreover, brown recluse spiders are very likely to be found behind paintings or under desks and tables. Brown recluse spiders are also very special by the way they have the eyes located on the body. 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. A brown recluse spider bite gets painful and itchy within two up to eight hours from the incident. The next thirty six hours are crucial for the evolution of the condition, since it is now that a deterioration or an improvement may occur; generally speaking, the ulcer and the necrosis will only appear within a few days if the health status does not improve. 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. Lots of videos with the camel spider cutting its prey into pieces and then consuming it, have been uploaded on the Internet. 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. They need to accumulate some fat in order to be able to resist without food during the period when they have to guard the eggs. The easy way to distinguish between males and females is not just body size, but also the length of the articulated feet. One other peculiarity of the camel spiders consists in the presence of several pairs of eyes grouped on various body parts.
