'Silkhenge' spider nests
'Silkhenge' spider nesting structures were discovered in Peru by research scientist Troy Alexander in 2013 .
Alexander posted a photo of the structure, which later studies at the University of Florida confirmed to be the nest of some kind of arthropod - presumed to be a species of spider.
The nests have a central pillar which are topped with a pod containing a few eggs. The pillar is surrounded by an intricately woven 'ring fence'. (see photo linked above)
The species which builds the nest remains unknown - as do the reasons for its intricate and unique design.
Some researchers have suggested that the 'fence' is to trap organisms which will later serve as food for the hatching spiderlings.
