Common name: Brazilian Wandering Spider
Type: Reptiles & Amphibians
Range: When you consider about the range of this Brazilian wandering spider, you can see this in the forests of Costa Rica and also throughout the South America including the places Colombia, northern Argentina, Paraguay, Guiana, Brazil, Peru, Ecuador, Bolivia, east of Anders and Venezuela. You can also see some of the species in the Amazon. This spider also introduced to Uruguay and Chile.
Size: The spiders of this kind normally have the capability to grow with the leg span of 13 to 15cm or 5.1 to 5.9 inches. They have the body length as ranged from 17 to 48 mm. The body size may be varied depending on the species and the largest species would have longest body. This species has the greatest body weight compared to other spiders of this group.
Diet: The adult Brazilian wandering spider prefers to eat mice, crickets, small lizards and crickets. The spiderlings would probably eat the pinhead crickets and flightless fruit flies.
Average lifespan: The average lifespan of this spider is normally one to two years
Habitat: The main reason for calling this spider as wandering one is that, it would probably wander out the jungle floor apart from concentrating on maintaining a web and residing in a lair. Because of this reason, it is also treated as the dangerous one by most of the people. When you consider about this spider, it usually searches for the dark and covered places for hiding during daytime in the case of densely populated place. It also prefers to hide within boxes, houses, cars, log piles, clothes and boots. This would probably cause an accident sometimes, when people disturb them.
It is also known as banana spider, since it prefers to find within the shipments of bananas. Because of this reason, the large spider that appears on the bunch of bananas would necessary to be treated with efficient care.
Breeding/Reproduction: When you consider about the reproduction of this spider, it would probably reproduce the eggs as packed into silk bundles those are treated as the egg sacs. In most of the cases, male spider would make the mating with the timely departure in order to escape before the female return to the normal position. You can identify the gender of this spider with the help of the end of their palps, through which the male spider would probably available with the swollen bulbs.
At the time of breeding season, the female spider would store the sperm inside it that too in the chamber and it uses it at the time of egg-laying process. When the sperm gets contacted with the female egg, it would get started with the fertilization. After that particular period, it would probably release out the young spiders.
When you consider about this genus spider, it is normally differed from other genus with the help of presence of a dense brush of fine hairs called as prolateral scopulae that are presented on the pedipalp tibiae along with the tarsi in both sexes. But, there are some species in this spider variety that would probably lack red hairs on the chelicerae because of the unreliable and efficient identification feature. When you go through the identification of this species, it would probably be done with the help of dark linear stripes or stripes that are presented on the frontal palps along with the presence of single thin black line running on dorsal carapace of anterior-posterior thing. Other features of this spider included with the strong ventral marking available on the underside of the legs that too with the contrasting talk mid-segments options and lighter joints. Apart from that, the pattern on the ventral of the abdomen of the spider is available with the several rows of black dots or in the color of red.
There is also an efficient and reliable character available with Brazilian Wandering Spider species for indication and that is the defensive posture presented with front legs that too as high one. It is also available with the correct color patterns to provide attractive look. At the time of defense display, it would probably life up the body into an erect position along with first two pairs of legs as lifted high in order to reveal the conspicuous black or light banded pattern available on the leg underside, and also the spider prefer to sway from side to side with cocked positioned hind legs.
When you consider about the web of Brazilian Wandering Spider, most of the spiders would spin their web with the help of silk, thin and strong protein thread like stand extruded from their body. It would probably find at the end of the abdomen that too as the spinnerets. Most of the species prefer to use this web for trapping the insects and some species like Brazilian wandering spider prefer to use it for their living and also to hunt. The silk emitted from its body would probably help for climbing, wrap prey, form smooth walls for the purpose of burrows, hold sperm temporarily, build egg sacs and also for some other efficient applications.
Since this spider is normally available in the forests of Costa Rica, when you go for the trip to that place then it would be efficient to go for the spider watching along with other animals and birds. They can found in Braulio Carrillo National Park, Chirripo National Park, Juan Castro Bianco National Park, Monteverde Cloud Forrest Reserve, Poas Volcano National Park and Santa Elena Cloud Forest Reserve. This would probably provide you with the option to get believed about the advantages and disadvantageous things.
It is more helpful for the students who want to go through the research regarding the dangerous spiders like Brazilian Wandering Spider. Most of the species related to this spider would probably be treated as the one to threat humans, not because of the toxicity and also because of the sufficient quantity of venom they produce.
