Good evening, everyone.
Here are three beetles. Identified as Ropalopus macropus. There are no problems with the lower one, it is clear that it is simply under-painted, there was not enough strength for the elytra. And the top two are questionable. They look somehow too natural in this coloring, as if it was intended that way. They were caught in 1991 in the cabin of a trolleybus on the window glass. They were sitting nearby. Macropus is a common beetle in Moldova, it is found in the city, flies on a light bulb, in gardens on drying apple trees under the bark. Yes, everywhere. And always black and usually 10-11 mm or smaller. It's the biggest black I've ever seen. These are 12.5 mm thick and somehow it is unlikely that two rare albinos found each other in a trolleybus. And I found them. Maybe it's not Ropalopus macropus?
By the way, I have never seen Clavipes in Moldova. Do we catch him at all?

All I can advise you is to get the determinants and atlases in your hands (or rather, on your hard disk) and go! And clavipes are caught in Moldova, at least 25 years ago they were caught.

Thank you. Clavipes is listed for Moldova in M. Danilevsky's Annotated List of barbels of Europe. Perhaps you should look for it further south, in the areas adjacent to the Dniester estuary. There are old fruit orchards there, they are already being gradually destroyed, I saw them myself. There are also Dniester floodplains, and a bit of forest. Interesting places.
But I was actually wondering if anyone had ever seen any mention of the stable, recognized light forms of Ropalopus macropus. I haven't seen it. The circumstances of the capture and the appearance of these two macropuses in the photo seem to be for this form. If not, then no. Remain as it is = undecorated macropuses.

And yet, about these beetles, I want to clarify (maybe someone will find an error. PLEASE!!!).
These are: 1 Chrysolina herbacea? found among thickets of grass, near the river
2 Clytra laeviuscula? there's
also 3 Geotrupes spiniger? knocked up in the bathroom on a summer evening
4 Hister fimetarius? in field
5 of Stenomax aeneus? on the wall of the house
6 Melolontha melolontha? found in the garden
of 7 Anisoplia austriaca? in the field
All photos from the rural area of the Ternopil region (western Ukraine)
I'll be waiting for a response...
