In Europe an unknown specie of 7 - 8 inches big spiders is spreading from Netherlands throughout the continent (now detected in Switzerland, Germany and Austria). They are very social and create large groups of up to many hundreds individuals. People encountering them are frightened and even arachno-specialists do not know what place on Earth are they from. Fortunately they are not poisonous but even scientists are frightened when looking at their groups.
