Definition of ground beetles of the genus Carabus

Community and Forum → Insects identification → Definition of ground beetles of the genus Carabus

Nilson, 26.05.2006 8:19

In this topic, we post photos of ground beetles of R. Carabus (and only them) for identification.

Colleagues, please help us identify (at least up to the subgenus) the karabus. Caught in the Caucasus.

And specifically in the Caucasus where?

26.05.2006 10:22, Guest Дзанат

Not Carabus adamsi. Similar.

26.05.2006 10:32, Nilson

And specifically in the Caucasus where?

Like, Adygea, oak and beech forest. Height about 500 m

26.05.2006 10:44, Nilson

Not Carabus adamsi. Looks like.

Yes, it seems similar, but the structure of the elytra... some of the wrong ones... not sure

26.05.2006 10:55, GuestДзанат

Here is my adamsi from the Caucasus, a beech forest, 300m high. smile.gif

Please help me identify the karabus. It was caught in the Yamalo-Nenets Autonomous Okrug of the Tyumen Region, in the northern taiga (larch).Carabus.jpg

Something from the subgenus Eucarabus Gehin, 1885 ?

Solidary. Eucarabus, looks a bit like either arcensis or arvensis.

Here look, maybe you can more accurately determine the benefit of the beetle in front of your eyes:

Carabus, found it today. Unfortunately, the photo is not very clear, because it was made on the phone. But I will describe: black, with pits and grooves on the elytra, with a blue border on the elytra, red thighs. Length 2.7 cm.

The picture, of course, is very informative smile.gif
Judging by the description, it looks like Carabus excellens. She just has variations with red thighs, other signs also coincide. In addition, it is definitely found in Moldova (if you believe the determinant of insects of the European part of the USSR). You can try to compare the ground beetle with the photo provided here. Coloration should be the last thing to pay attention to, since it is quite variable in this species - first of all, it is worth comparing the sculpture of the ndkr., the shape of the pronotum, etc., i.e. morphology.

26.11.2006 14:02, RippeR

Necrocephalus:
No, the frown.gifsculpture is not an excelence, and the color of the border is different. 1) Elytra bolee matte, not shiny! 2) there are only 2-3 rows of large pits located quite far from each other and small grooves between them, also about three rows 3) the pronotum is larger, it is about the same as the body in width

So look at the "Determinant of insects of the European part of the USSR"?

Well, then I don't know... The only thing that comes to mind (especially given the unusually wide pronotum) is Carabus stscheglowi. But again, this is just a guess, especially since I don't even know if you have it, and the dimensions obviously don't match. You can try to view photos from the "Atlas of Ground Beetles" on www.zin.ru, you can make a better photo and upload it to the forum. You can also use the identifier smile.gif

I think it's probably Carabus besseri. He has a black back with a blue border ,and reddish legs, and the size is suitable.

27.11.2006 11:56, rpanin

I'm sending you a photo for comparison

here! This is exactly it!!! Who knows what position of this beetle-rare, too frequent, relatively frequent, found everywhere around the world, the range is limited, etc.??

27.11.2006 17:17, Guest

The range covers right-bank Ukraine, Moldova, and part of Romania . It is found in steppe xerothermal areas. These specimens were caught in the Lviv region at the very edge of the S-W range. It is quite common in untilled areas. But since there are very few of these sites left, it turns out that it is extremely local.

28.11.2006 1:05, Necrocephalus

Well, since even RippeRIf the ground beetle was identified (from such a photosmile.gif), then I, perhaps, will also try my luck smile.gif

The ground beetle shown in the photo was caught in the Caucasus, at the very foot of Mount Beshtau, near Zheleznovodsk at the end of July this year. An attempt to identify it using the "Insect Detector". parts of the USSR" was unsuccessful.

I chose the photo so that the sculpture of elytra was clearly visible.

On the eye - Eucarabus cumanus, and, perhaps, in general granulatus?

No. Not granulatus exactly. Compared to granulatus, this ground beetle looks much more compact and stocky. The pattern of elytra is more smoothed (not as prominent as in granulatus), shiny. Especially strongly from granulatus my ground beetle is distinguished by the pronotum (I post a photo, for clarity). The size of the beetle is 19 mm. I looked at cumanus 'photo on www.zin.ru" it looks like my ground beetle is simapis. I wonder if there are any other species (other than granulatus) with which it can be confused visually, and how these species differ from each other?

Maybe this is ullrichi-the sculpture of elytra seems to be similar.

Nah, not ullrichi, that's for sure ! S. ullrichi is definitely not present in the Caucasus . C. ullrichi is 28-32 mm.

29.11.2006 16:08, Nilson

"Nah, not ullrichi, that's for sure ! S. ullrichi is definitely not present in the Caucasus . It is also too small for this species. C. ullrichi - 28-32 mm."

Yes, I guess so, I completely forgot about the place of capture.

rpanin is right, it's not ullrichi. Apparently, this is still cumanus, I have almost no doubts about this. I compared my beetle in detail with the photo of cumanus and did not see any significant differences smile.gifI wonder what size cumanus reaches?

2 okoem - cool photos!

Can someone tell me what kind of bug it is? . The modern interpretation of morphocarabus of the Trans-Carpathian region by various authors is a complete mess. Who can, and gives out.Possible variants: Carabus hampei var mendax Chiki 1906. Carabus seriatissimus Reitter, 1896. C. scheidleri ssp seriatissimus There were other variants, but they were rejected.
Female 30 mm, male 27 mm . Transcarpathian region Chernogorsky hr .Petros. h-1900 m alpine and subalpine locality.

It is difficult to tell from its habit - it is similar to C. scheidleri:
http://www.hlasek.com/carabus_scheidleri_11930.html
C. hampei on the Zino site is slightly different from yours:
http://www.zin.ru/animalia/coleoptera/images/carhamdh.JPG
Can't it be some other C. zawadskii?

What kind of work did you identify them for?

21.12.2006 11:41, Mikhail F. Bagaturov

Very similar to the humpees that I caught in Uzhgorod Komsomol Park, but of course not an expert, so I can not say.

This is where bloated endophallus comes to the rescue. Try to inflate them and see how different they are (although I'm not sure how many shapes from your region have drawings of the blown bag). But believe me, the surest way to compare. Sometimes morphologically identical individuals of Carabus aeneolus from different gorges (!) at a distance of 10 km have clear differences in bags.

That's what I want to work on next season . We need episodes from different locations . I used to throw everything away because of my inexperience taking it for C.zawadski .
So what is there to believe? Morphocarabus can have strong exterior aberrations ,and the endophallus is similar, and vice versa-similar in appearance, and the endophallus is different.
And yet, you can always find differences, but it is more difficult to determine up to the subspecies. Especially in many different interpretations. Here we need an accurate revision, on the ground, as they say. We'll keep working .

Now I have a question.
What kind of Carabus could it be?
Caught in Abkhazia (Ritsinsky reserve) at the end of June 2005.

It looks like sphodristocarabus yantinus or whatever it is today - as a subspecies of Armeniacus...

The Italians defined this animal to me as S. rugatus armeniacus = S. janthinus rugatus
