Help identify the
barbel Caught near Maikop in early August last year

I think it's Leptura quadrifasciata caucasica Plav., 1924

By the way, what are the characteristics of the caucasica subspecies? I have in my collection a specimen of L. quadrifasciata from the Yaroslavl region with the same pattern (not solid, torn) first sling on the elytra, as in the Madara specimen. Well, unless the black spots are bigger.

"It's different...pale yellow color of the elytra, always noticeably paler than in the European-Siberian subspecies... " and less development of the black pattern of the elytra. Well, and geographical distribution. I caught both subspecies, the difference is quite noticeable. The Caucasian subspecies looks like an intermediate form between the nominative and Leptura maculata.

Great Now I can edit my old post too: http://molbiol.ru/forums/index.php?showtop...dpost&p=1149072

It looks like, according to Plavilshchikov, this is your recurvata aberration... )

So, what's the problem?
Leptura quadrifasciata caucasica ab. recurvata Plav . , or not so?

Please tell me what kind of bug it is. Moscow region, June 12.

Is it really western (Melolontha melolontha)?
