In Catamarca, a abnormal phenomenon stunned the population of the Sumampa dike, within the Paclín division, when masses of spiders descended from the sky as though they had been paratrooper. That is the ñandutí species (Parawixia bistriata), firstly from Brazil, Paraguay and northerly Argentina, which is characterised via its semi-social habits and its talent to transport throughout the air via a procedure referred to as “arachnid flight” or “satan’s drool”. This tournament, outlined via consultants as a “rain of arachnids,” generated astonishment and worry within the house.
Mavens defined that this phenomenon is because of a herbal immigration strategy of the species, since younger specimens go away their unique colonies to discovered new communities. To try this, they use silk threads that permit them to drift within the wind and transfer to very large distances. Regardless of the visible affect that led to the large look of those arachnids within the Catamarca sky, the consultants confident that they don’t constitute a risk to people, since their poison isn’t of scientific gravity.
Along with reassuring the inhabitants, professionals highlighted the ecological significance of the Parawixia bistriatawhich meets a basic position in pest regulate when feeding in bugs. Due to this fact, they really useful no longer changing their colonies or looking to exterminate them, since their presence contributes to keeping up the steadiness of the native ecosystem. A long way from being a risk, this “rain of spiders” is some other pattern of the wealth and complexity of biodiversity within the Yungas area.
