Yesterday, I bought a banana tree (Musa Basjoo) from a local supermarket. Today, I noticed a hive of small spiders on the tree. I do not know where they came from, so I am curious to identify these small creatures. I am living in Flossenbürg, Bavaria, Germany.
Can someone help me identify the kind of spiders that are depicted on the photos?
