This Aplos simplex, a species of issid planthopper in the family Issidae, was my 10,000th observation uploaded to iNaturalist.

1st Butterfly (Superfamily Papilionoidea) of 2023, Celastrina ladon (Spring Azure, as Lycaena ladon) See an example in @BioDivLibrary at https://www.biodiversitylibrary.org/page/1595001

My 8,000 observation in @inaturalist was of Emmelina monodactyla (Morning-glory Plume Moth) https://www.inaturalist.org/observations/143759511

Though occuring globally, E. monodactyla is most extensive in North America & Europe
https://www.gbif.org/species/1859046

E. monodactyla was 1st described by Linnaeus (1758) in the 10th edition of Systema Naturae (v.1, p.542), as Phalaena Alucita monodactyla
https://www.biodiversitylibrary.org/page/727453

Linnaeus based his description on a pre-Linnaean work, Memoires pour servir a l'histoire des insectes (1734) by René-Antoine Ferchault de Réaumur (figures 12-16)
https://www.biodiversitylibrary.org/page/14375037

In 1905, JW Tutt established the genus, Emmelina in his article, "Types of the genera of the Agdistid, Alucitid and Orneodid plume moths" in The entomologist's record and journal of variation & assigned Linnæus' Phalaena Alucita monodactyla to the new genus

@dhobern gives a good synopsis of Linnaeus description of "Phalaena – All other moths" as part of his discussion of "Many-plume Moths"

@BioDivLibrary has many recent publications on E. monodactyla such as "Micro moths on Great Cumbrae Island (vc100)" by PG Moore in The Glasgow naturalist v.26:pt.4 (2018)

While in Belgium for the @GBIF GB29 meeting & side @BioDivLibrary meetings, I did some @iNaturalist viewing. While in Brussels, @botanicgarden01, & Tervuren (@africamuseumbe); I made 224 observations of 74 species (current as of this tweet). https://www.inaturalist.org/projects/observations-in-belgium

Harmonia axyridis (Asian Lady Beetle) was the most sighted, but there were also many birds, fungi, and my first observation of the Sciurus vulgaris (Eurasian Red Squirrel ) https://www.inaturalist.org/observations/138754122

But, perhaps the most interesting for me was the Fulica atra (Eurasian Coot), of which I logged 14 observations. @BioDivLibrary has a lot of information about F. atra, including the 1st description in Linnaeus's Syst. Nat. (ed. 10) (1758) https://www.biodiversitylibrary.org/page/727059

There are also many great illustrations, such as this one from The birds of Great Britain by John Gould (1873) https://www.biodiversitylibrary.org/page/53024004
