Suriname is surely extremely rich with species, hope I'll visit a tropical place like that in the next five years or so. I have a great online app for identifying plants : https://identify.plantnet.org
I saw that there are many mobile apps for identifying insects, but since I don't have a mobile phone I don't use them.
I identify insects and spiders through some good sites with European species ... but for some species I ramble through the Internet for hours before I find the name ... and sometimes I don't find the exact species ... but at least I always find the family. I don't know how is the Internet equipped with sites for South American species.
