This is apparently an invasive species in North America. It is native to Europe, western Asia and northwest Africa.

These look like various breeds of domestic geese and ducks. I'm not 100% sure, however, the ducks look like Rouen drakes and the geese look like Pilgrims and maybe Toulouse, but they could easily be mixed breeds.

I agree with Wildsweld.

I agree with Carole :)

Luna Moth caterpillars turn this brownish/golden colour and become less active in the 5th (and final) instar.

I agree with Sckel. Although Tree Swallows are very similar in appearance, the Blue and White Swallow is more common in South America.

This looks like a Tree Swallow, but it seems that they don't migrate far enough south to be in Brazil. I would definitely say this is a type of Swallow however.

This looks like a type of Sawfly Larva. I'm not sure which specific kind though.

Yes, I believe it's a good thing. I have registered too. Sometimes certain species and areas are under-represented. I had recorded a sighting for the Wood Nymph that apparently had not had a registered and confirmed sighting since 1985. It all depends on people getting online to help keep track of which species are seen where. I'm glad you took the time to participate. :)

This suggestion is for your first photo. The additional 2 photos are of a different sighting. You should separate them into their own individual sightings.
