Hobo Spider

1257


Hobo spider can be mainly distinguished for its fast and very active character. Hobo spider is very mild but very poisonous. Hobo spider was even rated among the ten most dangerous spiders in the world.
Hobo spiders do not weave webs like the other spiders because it’s not necessary for them due to the fact that they don’t stay in one place. They wander from place to place. In South America, these spiders are found in boxes with clothes and food or mostly in forsaken places

Hobo or Wandering spiders are found in tropical and subtropical regions of South America. hobo_spider_liveUnlike most spiders that spin webs, they do not live permanently in one place, from which it gets its name – “wandering”. In the daytime, they prefer to hide in cracks in the bark of trees, hollows and between the leaves of banana trees, which is why they are often called banana spiders. These spiders reach about 12 cm and have an elongated, brown body, entirely covered with fine hairs.Spiders including the hobo spider vary considerably in appearance, and identification can be difficult.hobo_spiders-1 Identification relies on an examination of the spiders’ anatomy. Like many species of spiders, the positive identification of hobo spider requires microscopic examination of the epigynum and pedipalps (the female and male sex organs respectively) and is best done by an archeologist. However, the following characteristics can be of help in the identification of hobo spiders or in order to prevent the misidentification and eradication of beneficial species with a similar appearance:hobo_spider_vs_brown_recluse

  • Hobo spiders lack the colored band found on many spiders of the Agelenidae family where the leg joints meet
  • The abdomen has chevron (V-shaped) patterns (possibly many of them) down the middle, with the chevron pointing towards the head.
  • Hobo spiders have a light stripe running down the middle of the sternum.

Hobo spiders do not have the two distinct longitudinal stripes on the top side of the cephalothorax, instead showing indistinctive or diffused patterns
hobo_spidersHobo spiders eggs.The eggs of the hobo are deposited in one to four egg sacs in late September and October. These egg sacs are made up of several layers of silk, intermingled with layers of soil and trash. The egg sacs are usually attached to the undersides of rocks, wood, or in materials located in yards, gardens and empty bags; each egg sac may contain 100 or more eggs. Contrary to some references hobo spiders are not prone to construct egg sacs inside living apartments (though they have been found in crawlspaces).
The eggs hatch mostly in the middle of June. The young spiders’ surface, feed, and largely remains underneath the face during their first season, molting their exoskeleton occasionally as they grow. The young spiders then overwinter, and are sometimes found indoors during this period.

When the spider encounters a person, it often takes a defensive posture. It looks like this. The body takes a vertical position. Its front legs rose up –which looks like the tapping mode black widow uses in defense.

Hobo Spider Bite

Wandering spider venom is less dangerous than the venom of snakes. Its venom is unlikely to kill a healthy adult human but only cause a severe allergic reaction, with which modern medicine is able to quickly deal. But if the Brazilian wandering spiders bite a sick person or a small child, the poison can kill faster even before an ambulance arrives.hobo_spiderHobo-spider-bite

Unlike tarantulas, which are often bypassed “dry bites”, these spiders inject venom into the area bitten in 90% of sacs and causes severe reaction.
Yet, the bite of these spiders in an adult human is not fatal and with timely treatment with serious medical attention, consequences can be avoided. But for children and people with weakened immune systems, its venom is deadly.

Hobo spiders poison. In any situation when you see a wandering spider, do not panic. Ordinarily, it does not attack man but bites only in self-defense. Therefore, it is best to just stay away from it and not to provoke bite. The controversy surrounding the spider bites is vagrants. However, these spiders are often confused with other species. In fact, misinformation on Hobo spiders are so common that previously thought that they are able to produce necrotic lesions like brown spiders. Nevertheless, the majority of such sacs, evidence have been circumstantial.

On its own, wandering spider does not attack humans. It bites only in self-defense. But the problem is that these spiders like to hide and are very difficult to see. If you found wandering spider, try as quickly as possible to get it out of the house and check every boxes and cabinets: whether there might be others. 

Hobo spider infestation. Hobo spiders’ bite can be distinguished mainly by viral infections and also by Lyme disease and should be considered as a possible disparity diagnosis in areas where there is either the deer tick or the western black-footed ticks. Other likely differential diagnose of spider bite include erythematic, scald skin disease and Stevens-Johnson disease. At least series of other disease states which produce coetaneous manifestation have been implicated in the “spider bite” sacs.

It got its name wandering spider because they roam the jungle at night. They do not burrow, they do not spin webs. During the day they hide under rocks, under termite mounds, among banana plants. In short, prefer dark and damp shelter. Also, I loved to wander close to human habitation or directly inside the house.

Here are some helpful hints about identifying Hobo spiders:

  1. If you are bitten by a hobo spider, don’t kill it, but do hold it and trap it because it is impossible to recognize the spider in a brief.
  2. If it has striped on the legs, stripes on the abdomen or pointed palps, it’s definitely not a hobo spider.
  3. Remember that there is no specific way to accurately identify the spider. You can only rule out the possibility that it’s a hobo spider. Even scientists, who study spiders, cannot fully identify the spider.
  4. Do not kill all the spiders that were identified as non-hobo spiders, Brown Recluse and Black Widow.
