Spotting

I'm always wondering, what this "cotton swaps" are, which are hanging in zilla, acacias, etc...

Thanks so much for the info, Ingrid3! You are right - I have only seen these towards the tops of plants.

You should definitely post this an the mission for animal architecture and webs! It is such a great picture!

This could be a spider temporary nest. I find these alot built by tin salticid spiders in grassy almost 1m high planted fields ONLY at the very top of plants. Its like they are trying to get as high above the ground as possible. They seem to build them for overnight stay, they are often gone the next day. I call them spider bivouacs. It is also possible that they are egg cases, or more permanent nest and when I find them the resident was predated upon. I would have to video tape one to find out!

I'm so curious about these - I see a lot of them, too.

I have shots like these and have been wondering which insects create these.

So true! :-)
