Our trip to Argentina had, as one of its objectives, of adding to iNaturalist observations. The iNaturalist platform can be used to easily see where one’s observations fall – in terms of categories of organisms. For example, how many bird species did we see and how many observations did we make of birds? The same can be asked of any other group of organisms (or any biota). One does this by selecting the “filters” option and putting for location Argentina, the dates of your travel, and the observations by yourself. The image below shows this. Rosario’s iNaturalist account is “argonauta”.

For our recent Argentina trip in 2026 the results can be summed, as mentioned, for any group of biota. Here are the observations and species for some groups of interest (to us):

Biota	Observations	Species
Insects	1656	486
Moths	857	159
Butterflies	66	39
Beetles	351	121
Plants	743	329
Bromeliads	102	25
Cacti	154	40
Amphibians	7	3
Reptiles	5	3
Mammals	21	4
Birds	339	128

Although birds are much more conspicuous than other organisms in most environments, they have fewer species than insects, especially moths and beetles. The numbers of species for the insects is currently an underestimate, since many species have not been identified. Of course, there are multiple observations for many organisms since these can be observed in different locations and different times.
