This is fascinating. My first question would be what are they catching?
What can sustain that number of spiders so far underground?
Also, this web is so dense it looks like a solid sheet of silk, studded with the remains of its past victims. Wouldn't that be a little too conspicuous? I thought spider webs were supposed to be nearly invisible to the prey.
Every part of Earth's crust is jam packed with life.
From the article:
> The vast spider population is attributed to an abundant food supply: more than 2.4 million midges in the cave, ready to be entangled in the intricate web.
...although I guess the question then is what sustains the millions of midges!
