Are you splitting Turkey Vulture? And not splitting Cane Toad?

I’m just going with the taxonomy of the Princeton Birds of Costa Rica Book.

And the most consideration I’ve given to cane toads is not kicking them out of the way when I meet them. :p

I don't think this can be counted as you haven't managed to identify the Polistes to species level.

I also thought that but I saw that users like @MRJ and @Mr. Zootycoon do that without anyone pointing it out so I thought it is okay

Ah okay, fair enough. I had never noticed, if it is allowed I may start as I have many inverts that I could add to my lists.

Do you have examples of this? I can't see any in the posts they have made in the thread.

Unidentified species cannot be counted here. The only way a "sp." would be allowable is if it is a known taxa which just hasn't been described with a scientific name yet.

Another weekend, another wildlife adventure!

This time I went looking for something quite out of the ordinary, for it is not every day one can see an entirely new class of chordates. It was very brisk morning when I visited the Veluwe with friends, the heather still covered in a thin layer of frost. The area is well-known for a diverse reptile fauna, but given the temperature it was no surprise we didn't find those. Instead, we went looking along a small but very clear stream to find a rare inhabitant of gravel banks: the brook lamprey. The search itself was rather anticlimactic: finding the lamprey was super easy, barely an inconvenience. We watched them for a good while, then went on a walk in the surround area which did not produce many wildlife sightings but was very pleasant nonetheless.

The inverts are just a bunch of species from all over the place. I'm a little on the fence still which groups I'm going to record in detail, so maybe the next updates will also feature spiders or true bugs or neuropterans.

Fish
1. Brook Lamprey, Lampetra planeri
2. Three-spined Stickleback, Gasterosteus aculeatus

Butterflies
4. Comma, Polygonia c-album

Moths
3. Fox Moth, Macrothylacia rubi

Bees
2. Red-tailed Bumblebee, Bombus lapidarius
3. Tawny Mining Bee, Andrena fulva

Beetles
5. Minotaur Beetle, Typhaeus typhoeus

Flies
1. Hoverfly sp., Meliscaeva auricollis



100-butterfly tally: 4/100*

* Given how things are moving, it seems like I might actually have a shot at this! I'm not going to be obsessive about it, but I'm very eager to see how many I can get.

Sorry for the mistake, my total for INVERTEBRATES is now 11 animals and my big total is 65 species

Where he has "1. Hoverfly sp., Meliscaeva auricollis" the "sp." is because the hoverfly doesn't have a common name, it isn't an unidentified species.
