Fotik of course old, Konica Minolta DiMAGE Z2 is called. I attached a lens in front of the lens and so I shoot. Although there is also a "macro" mode, but it turns out even worse, because it is too small. In general, I'm experimenting.

With a lens-yes, it is usually more convenient, the focal length is longer. Native macro is only suitable for flowers and large beetles. If you shoot without a flash, it is advisable to give maximum light. Close to the lamp, for example, or on the window to remove, and not in the back of the room. For depth of field, the maximum aperture is clamped (but acc. the shutter speed increases). You can shoot those who have been tested from a tripod (with a timer for a few seconds) or just put the camera on so that there is no hand shake.

barry, how do you manage to focus at all? The beetle is crawling...

"Crawling" is an understatement, mentally unstable people are difficult to catch even in the frame, not to mention consciously getting into focus. In severe cases, I simply make a lot of shots "on the ball" by throwing them to the intended place, then I review them and select them. Sometimes dozens of them. Well, why I use sand also helps... I make a cone funnel - even fast beetles sometimes just row along the walls, or move up quite slowly, despite the frenzied footwork. For some reason, they all have the instinct to run out of the pit and up. By the way, maybe they will also run into the cone hill and sit there? Although I seem to have already experimented on this topic...
Well, because of the flash and short shutter speed, even running beetles are obtained without smearing. In general, I optimized the shooting mode for the field/nature. But recently, most of the emphasis on dropping out is being made, so you still need to shoot at home. Yes, and even in the field sometimes come across quite rare, which you see for the first time in several years, in the field somehow experiment with shooting and does not pull, it is also better to shoot at home.

but cur-5 is an interesting elephant, this is of course Phyllobius (Metaphyllobius).
I can see his hair sticking out and his legs are reddish. I would like to call it the boy Ph. glaucus (Scopoli, 1763). Look, are his thighs covered with fine hairs, or do they have the same scales as on his elytra?

There are no hairs on the thighs - only hair-like scales, slightly thinner than on the elytra. According to the green determinant (I only looked at the genus Phyllobius), it turns out like Phyllobius calcaratus - this, as I understand it, is a synonym for Ph. glаucus? But the legs are clearly not red (and not even slightly darkened, as in the key - I would say-very darkened, brown...), and its size is 9.5 mm, which is slightly larger than in the key... Is it just such an instance, or could it be something else?

there are only 2 options - Ph. pomaceus (=urticae) and Ph. glaucus (=calcaratus)
these guys are extremely variable, including the color of their feet

Maybe you can help with a few more beetles from different groups - most of them are probably banal... Early May, south of the Rivne region (Ostroh district).

1. I'm not really in Dorcash, but for me so Pedestredorcadion holosericeum
2. Mesosa curculionoides
3. Asemum, I think striatum
4. Valgus hemipterus, male
5. aphodius of some sort. I pass
6. Calosoma
inquisitor 7 and 8 Schizotus pectinicornis, male and female respectively
9. I think Ischnomera sp
10. I think Scaphidium quadrimaculatum
11. Thanasimus maybe formicarius, look from below, if the middle chest and back chest are red, then it is, if black, then femoralis
12. kozheed, maybe Attagenus pellio
13. Omophlus sp.
14. Stenomax aeneus others like in Ukraine there is no
15. It seems like Gonioctena decemnotata, but to be sure pussy need to pull
16. Platycerus http://www.zin.ru/ANIMALIA/Coleoptera/rus/platyce2.htm
17. Lilioceris lilii
