Interesting story about a web weaving spider that creates objects that look like it to act as decoys against predator (in the article wasps) attacks. I’ve read about plenty of methods of predator survival methods, but never constructing dummy sized objects for decoys…
Regarding the second article and Harpactea sadistica, this one was dicovered by czech scientists Milan Řezáč. Some info is here http://www.biolib.cz/en/taxon/id652849/
sorry, only in czech, I should translate it also… 🙁 , but you can watch some videos at least and find the primery literature (actually I think I should have it somewhere…)
