Kinda freaky.
They look like tent worms to me.
Google images for tent worms and check it out.
Those are the same images in the link from this thread.
Some species of tent caterpillar.
The cobwebbed bike shots are pretty freaky!
Wow…I’ve never gotten ill looking at tent caterpillars before. I’ve onl;y ever seen them make a few dozen tents up in the branches. Cobwebbing over the ground and engulfing a whole bicycle man that’s…freaky.
Could you tell me where these pictures were taken.
I have never seen such an infestation of tent caterpillars.
Did this happen overnight??
The pictures seem to be at a Swedish website. The larvae could be larvae of ermine moths who tend to form webs.
Here are a couple of links to photos at Swedish websites of what in Sweden is called Häggspinnmal (Iponomeuta evonymella) which does the same.
Unfortunately all I can reply is that I have the same two pressing (burning! burned in my mind, I had a wrteched dream about these images) questions.
