Hello!
I have a bug in my jar. In April, they brought me some "strange" fruits from Indonesia (from Sumatra, I think), just as souvenirs, and at some point this friend chewed his way out of one of them.
I put him in a plastic jar and since then I occasionally think about him, I try to feed him either with nut shavings or honey (but I don't even know if he eats these grubs).
Mostly, he wasn't too active all this time. I sat and meditated. But in the last few weeks, I think, he somehow gave up, looked haggard, sad.. And then I finally asked myself, " Why am I keeping it? I'm not a colopractor... I'm not a coleopterist

, and in general - I'm afraid to say it here - I'm not interested in beetles.. And I remembered that there are amateurs.

In general, I attach his photo and a photo of the nut (?) from which he "hatched". Walnut - the glossy one with a wing in the lower right corner of the frame.

My friend, I think, has an attractive appearance and a calm disposition. It's like something out of a good cartoon. Nothing Alien, nothing Kafkaesque.

I could have delivered it this week on any day, Moscow, Prospekt Mira metro station.

And my beetles, which I posted yesterday, so no one wants to identify? I completely don't understand what I'm doing wrong - I took a close-up picture of the male and female, wrote the label, and even pointed out the parent. But for some reason, this is the second time they persistently ignore it...

No one wants to, that's fine. These are quite difficult beetles, very changeable, just from the picture above, nothing is clear. Even if you hold it in your hands, it is often not clear. Females in some species are not identified. The image of the male shows no significant signs: the structure of the antennae in terms of the presence / absence of spiked angles, the structure of the mandibles, the structure of the keels on the head.
I would check for P. friendi vs P. superbus compliance. In favor of the latter.
In this case, under the mandibles should be hefty curved teeth-processes, like in kravchik. But the sculpture of elytra is not typical.

I also tend to think that this is a black form of Superbus. But on the Friendly imho they do not look like. The fact is that I also have Friends. And as if anticipating that someone would write that this is a Friend, I took a picture of them together for clarity)
Even if you do not take into account the difference in size, because they can vary greatly, then in Friendly, and in both sexes, the processes on the chest are much larger, sharper and longer. In the sense of large beetles, they also have them, but they are much less pronounced than in smaller Friends, although in theory it should be the opposite, the larger the beetle, the more pronounced its outgrowths. Yes, and they are very different in shape - the Friendi is more "downed", and the Superbus is more elegant, it immediately catches the eye,

The differences presented in the keys (i.e., they are diagnostically significant in the authors ' opinion) are reduced to the size and shape of the submandibular tooth in the male and the different sculpture of the elytra - rough worm-like wrinkling at the base and smoothed distally in the superbus and b.m. uniformly rough throughout in friendi. What's really out there... In Ivo Jenis's atlas, such a beetle is generally called "P. sapphyra". I never even found out where he got the word.

Good afternoon, dear entomologists! Can you tell me what kind of weevil was in the finch's stomach??? 15.06.17. village of Kamenyuki (National Park Belovezhskaya Pushcha), Pruzhansky district, Brest region.
From the entire beetle in the stomach, only the abdomen (size 6 mm), limbs, and parts of the head were preserved. Prsp. and the whole head, unfortunately, no. That's the big problem.
By what can be called the head, it is clear that the antennal grooves are lateral, located on the sides of the head tube, there are no pterygia.
Lower legs without spikes. The claws are loose. 7 segment of the flagellum is not enlarged, separated from the club. The tops of the elytra are not elongated into processes, as can be seen from the photo. Based on the size of the abdomen, I assume that the size of the entire beetle is approximately 9-10 mm.
I think it might be Tanymeus palliatus, but I'm not sure about that.
I will be glad to get your advice. Thank you in advance!

in my opinion these are the remains of Brachyderes incanus
