Divination was the first time when such" redheads " as L. bardanae were no longer seen on the Macroid.
The second time I already went through the determinant, but many terms are incomprehensible to me, as a non-specialist: elytra gaps, etc. - I came out in general on L. iridis, but I discarded it-it's painfully different. Only then I came across Lixus pulverulentus, and the greatest width of the elytra in the anterior third and the food plant were decisive for me.
According to your link, I would go to the right (large, rounded blades) - the shooting angle is probably the same, and there among the Ukrainian Lixus linearis and Lixus punctiventris, but they are less similar.

Actually, there is nothing complicated here. You just need to take the beetle in your hands and turn it under the binoculars.

Bardanae has thick, massive legs, large postorbital lobes and, most importantly, a belly without bare spots; it lives on sorrel. Punctiventris and pulverulentus have a glabrous belly and live on "spines". Pulverulentus, in addition, has very characteristic tooth-shaped postorbital lobes (in live beetles, it is often difficult to see due to the abundance of pollen, it is better to wipe). I see a thorn in the photo and rather tend to punctiventris, but you need, again, to look...

Thank you all !!!
I understand, but there is no beetle, however, as well as a binocular-a photo, and even then only one, last year's (
In any case, now I will know what to pay attention to.
Let's limit ourselves to sp.
