A lot of" Cherepanovskys " went into synonyms.
Question : are there any clear external differences? or just the" floating " genitals? and if genital, what is the range? then, all the "old" instructions should be rechecked. Here, it seems, banal beetles, and such problems
PS has anyone seen mainland Rhagium (s.str.) japonicum? or is it a purely island view? and how much does it look like?

Nice view. There are no mainland ones, as far as I know. I can't describe the differences in words, but if you put it next to rugipenne, it's not difficult to distinguish. An example of a similar situation is Paragaurotes doris ussuriensis.

Good time of day. Help me determine the name of the barbel beetle, I think. A visual search on the web for exactly the same thing did not bring results.

The beetle was caught in my place of residence , Tashkent, Uzbekistan, on March 11, 2014. When pruning a willow tree, larval passages were found, and this beetle was sitting in one of the chambers. The beetle makes a distinctive creak when you touch it .

The bug is still alive, more than two weeks old.
I would like to know if it feeds on something while in this form, or if it lives its life on the substances accumulated by the larva? And how long he can even live. Lives in a spacious plastic 10-liter bottle, with sawn fresh sawdust of willow wood and chopped pieces of pine and the same willow.

Thank you in advance for the definition.

Greetings, happy spring holiday Nauryz!!!
You have a barbel Aeolesthes sarta (Solsky, 1871), it does not feed, the choice is yours to give it life or if you want to immortalize it in a frame.

Thank you for your congratulations! We also wish you a happy Navruz holiday)

Grant him life and he won't freeze? I remember the years of such beetles in the beginning and middle of summer, and right now only the beginning of spring, and we are not very warm, rainy, cool.

It's tempting to immortalize it in a frame, but wait until he leaves this world, and how long to wait, or put a thread to sleep in a humane way?)

I like barbels for a long time, and now I found one, I think now I'll slowly start collecting a collection) It's interesting to find out what other barbels live in our country.

Yes, this is a wireworm-a nutcracker larva! But most likely already dead before the beginning of the legend)))))))

That's not so. All known members of Bothrideridae: Bothriderinae are external or pupal parasites of various xylophages, including bark beetles, false bed beetles, weevils, barbels, and carpenter bees. Development occurs with hypermetamorphosis, like abscesses. In Bothrideres bipunctatus, the larvae develop as external parasites on injured or weakened xylophage larvae, especially on Xiphydria horntails. They pupate in silky cocoons.

Biology is described in some detail in this paper:
