Last summer on the White Sea coast in the district of d.Gridino (~ 66° N) (rock pine forest biotope) found beetle remains under the bark of a pine tree. Unfortunately, the strong wind and my clumsiness did not allow me to collect all its parts Having some experience in determining and having collections on regional fauna, I thought that determining this rather large species would not be a problem, but I came to a dead end... . Knowing that the forum has a sufficient number of fans of the family, including professionals, I ask for help from specialists. The length of the elithra is 14.5 mm, the estimated body length is about 20 mm.

I am, of course, for Arhopalus. On Rhagium, these mortal remains do not pull at all...

Look at the whiskey, look at the whiskey (considering that the head is eaten off from behind) - Arhopalus did not lie next to it

You must be laughing. What is Rhagium? Compare then the front thighs, the shape of the shins, if it seems that the head is eaten, although in fact it is not damaged at all at the base. In ragii, the head is rather narrowed to the base and clearly longer than the width at eye level.
Arhopalus rusticus was under suspicion, but something stopped me, and now I don't remember what. I compared the remains with both the collections and the atlas of the Leningrad region, and something did not grow together, or maybe it was gender differences?
And in A. tristis (ferus), the legs will be more slender, and in order to look at the 3rd segment of the paw, unfortunately only the middle paw has survived, and the back one would be needed

, and it is more rare.
Will there be more new judgments? Arhopalus rusticus is still in the lead

Arrhopalus sp. Look at the third segment of the foot, if it is dissected to the base then rusticus, if to the middle-then ferus.

I also thought for a whole year that the narrow wing, then suddenly "dawned" that the sawyere and up to this point was under this impression, even "remembered" that the eyes with a tenderloin))) Now again I have to admit that it is quite itself-it, and the eyes are round, and chl. paws are still almost dangerous) Amazing - I have never seen such things again).
Chlorophorus varius means not only light green happens.... In the Crimea that-whether they are such or not only....
Many thanks to Everyone!

She seems to be a male. It's just that the photo isn't very good, so I doubt it. But you can compare your own copy. with images in the Internet. I haven't seen them myself in the Moscow Region, so I'll ask Nikitsky about their presence. The color of Chlorophorus barbels can be from gray to bright yellow, and, according to my observations of live beetles, it can change over the course of their life. Beetles that have just emerged from pupae are colored in gray-green tones, then gradually turn yellow. But if the beetle is killed, it no longer changes color. The same thing happens with other genera of barbels, for example, in the genus Saperda. I asked on the forum why this happens, but none of the specialists in the group answered me.
