Identify insect, possibly Popillia japonica

The title of the photo c:File:Coleottero giapponese o Scarabeo giapponese in accoppiamento.jpg says Popillia japonica. Location according to uploader is c:Category:Parco del Curone, Lombardy, Italy. This puts me in a stalemate where I don't dare to categorize it into c:category:Popillia japonica because I'm not certain the title is correct, but don't dare to tag it c:Category:Unidentified insects either because the identification is right there in title. Please help resolve this either way (or categorize to a taxon larger than species but smaller than class) if you're more familiar with insect identification than me. – b_jonas 08:28, 16 July 2025 (UTC)[reply]

I don't see a problem. The article Popillia japonica states it's an invasive species in Europe - "In 2014, the first population in mainland Europe was discovered near Milan, Italy." 196.50.199.218 (talk) 08:54, 16 July 2025 (UTC)[reply]

Totally a Japanese beetle. Abductive (reasoning) 09:04, 16 July 2025 (UTC)[reply]

Definitely. They've been common in my neck of the woods (North Carolina) as far back as I can remember. Just because a ___location is referenced by the scientific name doesn't mean that the species is only found in that ___location. It may even have been extirpated in the nominal ___location. --User:Khajidha (talk) (contributions) 12:26, 16 July 2025 (UTC)[reply]

Thank you for the replies, I'll add the category. "Japanese" wasn't what bothered me. It's just that since it's a common species, the uploader who needn't be an expert could misidentify a different insect species as this. – b_jonas 12:59, 16 July 2025 (UTC)[reply]

Thermotogati and Bacillati

Hello,

I'm confused: are these kingdoms one and same or are they different? Wikipedia is rather unclear about it, because the phylum Deinococcota is included in both.

Some of the difficulties with bacterial taxonomy are given in that article. Abductive (reasoning) 12:09, 17 July 2025 (UTC)[reply]
