The worm inside the bag-like structure is called a bagworm, they carry it around to hide inside.
The brown worm is a butterfly, a very large and beautiful swallowtail. It's camouflaged to look like bird poop.
The spider looks like an old female Latrodectus curacaviensis and they are quite venomous so be careful. They are shy and slow to to bite but make sure that you never trap it in your hand accidentally.
I don't know what the last one is
That worm in the bag is not a caterpillar then?
If it's a worm, is it going to eat my plants?
Wow, that butterfly must have already been born, but since I don't follow them, I missed seeing it.
I have seen this spider very frequently in my garden. I have taken very nice photos of it before, but it has never jumped on me, that's why I thought it was not poisonous, I will be careful from now on. I just don't like killing them.
Thank you very much for this information.
Friend Nikv, are you a biologist or something that has to do with nature? because since I have known you you always give me reliable information about plants, insects and others.
It is a type of caterpillar and the different species eat various things so I don't know for sure.
I'm no biologist but I have been interested in the natural world since I was a child and always educated myself about it
I really congratulate you for all the knowledge you have acquired. I forget names a lot, I'm not so good if I don't write it down and review it later.
Thanks, again.
