White-tail spiders


Hello Reader,


The spider of today is another with some mystification. The white-tailed spider. A confusion that is made with this spider it is that the venom can make the location of bite necrose, however this is not scientific proof and all the attempts to see this fenom point that don’t happen. The spider who is proof to do this lives in Brazil, normali know as brown spider.



Male L. cylindrata
Female L. cylindrata
L. murina





The venom injects on the bite of the white-tailed spider don’t spread on the body, stay in a range of the bite, causing a local swelling, pain and itchiness. In rare cases cause nausea, vomiting, malaise or headache. You probably will not have a doubt that this spider bite you, once the bite hurts like a bee sting and give an immediate burning sensation. But don’t worry, a good pack of ice can help with the pain, not more than that is required, but the red marck can stay during 5-12 days.



This spider is not aggressive, just wen treaden. In the case could be by accidental since this spider likes to hide in the middle of the folds of clothes, towels and shoes. It don’t create a web, hunting other spiders, she vague around during the night after her pray. She can even help hunting the Redback spider and black house spider that make part of her diet.



The white mark in the adults can be less visible then in the young, who have a easy observable white spot.

Ibises


Hello Reader,


Today anotar bird to talk about. The Ibises.




It is a bird far spread into the world, except in Antarctida, habiting forests, plains and wetlands. But I focusing in two species of ibis, the straw-necked and the australian white ibis.





and




This two species of ibis have the costume of get together in a huge flock on the season of breeding when they coexist. They have a time to normally procreate in the year depending on the region were they are, but have some cases when occur after a big rain in any time of the year. They also can create their nests in a place where other birds like egrets, herons, spoonbills or cormorants, who also build nest near a corp of water.




The most common ibis to see is the australian-white-ibis, because it have adapted well to the live in the city; While the straw-necked ibis don’t have adapted to cities, but have a good relation with farmers sins they eat the plague insects. The australian white ibis is consider in some places a plague in the city due their unique bad smell and they also turn garbage cans and even stole sandwiches of picnic baskets.





The australian white ibis get so long in the city that they even abandon their usual place of procreation to stay in the same place, building their nests in rivers that cross the town.
