Identification of beetles (Coleoptera)

Thank you very much, Dmitry!

Bulgaria, Burgas district, Sozopol 09-20. 06. 2017 20 mm
He named the beetle Laemostenus (Pristonychus) pretiosus Faldermann, 1837, but of course there is no certainty. Like a European view, in Bulgaria on the Black Sea coast can run?

Most likely Laemostenus (Pristonychus) terricola. For Bulgaria, ssp punctatus (Dejean, 1828) is given
. Also, see the antithesis for Laemostenus (Pristonychus) cimmerius - he is also a father-in-law there...

Help me identify Lixus.Lixus ? angustus I have several pieces of them, all were in a pink coating when caught in nature.

Thanks for the tip. This is not a terricola exactly, there is no good sign-brushes of hairs on the middle shins. My terricoles have it. And what about cimmerius-and "he is there too" - is this in the sense of Bulgaria? In Green, the habitat is specified specifically-mountain Crimea. If he also runs in Bulgaria, then cimmerius is a very suitable option. However, I still have nothing to compare it with, there is no material.

Hello everybody! Yesterday I posted this photo in the "Definition of Carabus", they wrote that this is possible: "Calosoma (Campalita)? chinense, male (poorly visible from the phone)". Please tell me, if you can be more precise, and then I'm in that topic now something not to enter and not even thank, from another computer. Yuzhny Sakhalin, 22.07.17 I will post all 3 photos that are available from the TLF. Yes, it's so dark, dimples shine, flew into the light.

About 2.5 mm. Pronotum with lateral well-marked corners. The base and sides are covered with rounded scales. The dots are large and quite thick. The median groove is clear at the apex and at the base. On the elytra there is a weakly limited scutellum spot, which extends to the second gap, rounded bristles also go on the gaps on the sides, along the lateral edge of the elytra a thicker strip. Gaps with two rows of hairs. Along the seam there is also a row of rounded white scales. Thighs without teeth. Claws without teeth.Ceutorhynchus (gr. cochleariae)?
The legs are dark.

check for Ceutorhynchus typhae, this is not gr. cochleariae because there are scales in the grooves, and in cochleariae the grooves are bare

Crooked-legged Colosoma chinense is hard to confuse with someone else.

Good evening.
Here is a pollen-eater, I would like to clarify it. Please tell me who he is.

It is very strange that there is no brush of hairs - this is a characteristic feature for the subgenus Pristonychus. Cimmerius has this feature. Then it turns out that this is not Pristonychus, but a nominative subgenus, from which there are two species in Bulgaria: Laemostenus(s. str.) venustus and L. (s. str.) complanatus. And the size of 20 mm is too big for them and speaks rather in favor of cimmerius. The network has images of all the designated types. Take a look, compare it with your instance, and check the signs again. I have a cimmerius from Bachkovo (Zap. Rhodopes), (for the Balkans its subspecies is given) but how it differs from the Crimean ones, I did not understand. A very complex group, often the species differ only in genitalia. Check out Georgiev's works, in particular this one: Catalog of the Ground-beetles of Bulgaria

It doesn't seem to be a pollen-eater, not an Alleculidae. This is Dascillus cervinus Linnaeus, 1758, Dascillidae

All settled on Laemostcnus (Pristonychus) cimmcrius wcirathcri G. Mililer, 193I. Subspecies specified for Bulgaria in Georgiev's paper. It's too big for the groundcover, plus the grooves-the gaps are more pronounced. As for the brush on the middle shins, some increased hairiness is still observed there. So the subgenus is correct.
And in general, I already have a terricol, but I haven't had a zimmerius yet !!!
And it also turned out that there are no special European abacuses in Bulgaria, and the beetles caught there in the Dunes are our Abax parallelepipedus. Only they look like this:

I still think it's Pterostichus (Feronidius) ssp.- not Abax. but maybe I'm wrong - the photo is also tilted forward. there is a male and it can be torn through.

That's the one! pancake...I had them...thank you!

Pterostichus is even more interesting. I was thinking about Pterostichus, but beetles have very characteristic abacus "shoulders" with a protruding 7th gap. In other pterostichs, I have not seen such
a thing, so I retook it, but it doesn't turn out any sharper. The beetles are clean, this choto glitters in the sun..
....In Bulgaria, there were two Feronidius-melas, but this is definitely not it, and incommodus. This one is more similar, but the sides of the pronotum are too rounded. http://carabidae.org/gallery?taxon=9298 I'll look among other subgenera.
----- In short, the topic is closed. 1. This is definitely not Abax. 2. This is definitely a ptrerostic from the subgenus Feronidius. 3. This is definitely not melas. 4. This is incommodus. Photo on the website http://carabidae.org/gallery?taxon=9298 slightly knocks down its pronotum, but the photo on http://molbiol.ru/forums/index.php?act=Att...=post&id=281244 in the Honza box-just one to one. It is also specified for Bulgaria. Hurray!
Thank you very much for the help of Archypus and I. solod.

Why not melas? Where did you catch him?" After all, incommodus ukzan only for the very west of Bulgaria! See more keys here http://www.coleo-net.de/coleo/texte/pteros....htm#hungaricus

I have Moldovan melas (a lot) and Corsican melas (4 pieces). I've already put them all together - the Bulgarians, the melas, the melanariuses, and the abacuses. Molasses, both Moldavian and Corsican, are all similar to each other, and not like Bulgarians. They differ from the Bulgarian ones in the shape of the elytra and especially the pronotum. In molasses, it is much more convex and expands from the base to the head. As if slightly heart-shaped. For Bulgarians, on the contrary, it is flattened and does not expand. The indentations of the prdnspki also differ. Yes, and just next to there are two types and it is clearly visible that they are different. Even if you want and with a stretch for molasses on will do.
Bulgarian beetles were caught by a man who was resting in the Dunes, but he said that he went to set traps in the mountains. But the mountains, though small, very close to the village.
To be honest, I didn't understand exactly where incommodus is found in Bulgaria, I just didn't find the given geographical abbreviations on the map in Georgiev's work. But this work is also more than 20 years old. Of course, there is no complete confidence in incommodus, and only the description in Russian or a good photo of a reliable incommodus can save me. I don't pull genitals, I don't know how.

Good evening. Here are the larvae of softlings, caught in the winter in Leningrad. Is it possible to identify them?

the ceratopogonid woodlouse probably settled in there for a reason.

and the bronze is lower - it seems like a very bright white. well, you know better! Thanks)

And for what purpose?..

And for what purpose?..

many of them are fed on other insects.

Hello everyone. I had three Moldovan Dixuses, and I identified them as clypeatus. But they were in different storage boxes. And so I combined them, and it seemed to me that they were not one, but two types. One beetle (Chisinau, first photo) is larger - 12 mm and noticeably tadpole. And the punctuation, especially of the head, is different. The second one is cut, 11 mm (the second one is the same -10 mm). It seems to me that Rezensky is an eremita. Both types are specified for Moldova. We also have an obscurus, but it's different, I have three Crimean ones. There are some conflicting keys in Green, I think.
Maybe it's clypeatus and eremita? Or even vice versa?

It seems
to me that Here, maybe it will help: https://cloud.mail.ru/public/EZL2/Ve7gETK5r

I would classify both of them as klipeatus. It should be caught serially in Moldova, even superficially and manually. At least that was the case 25 years ago. Eremitis without indentations on the head.

Yeah, well... zrada. And I have already rolled out my lip for a new look in the collection. But the head of the first one is still proportionally larger. It will be necessary to catch more beetles and compare at least small series. But it is better to look for dixuses at sunset, they climb up the grass to the spikelets. I saw them so en masse in Koktebel, though on a limited area of the field (football). And for me, evening walks are almost inaccessible. I'll try to put the glasses where I caught bighead. Thanks to stierlyz and Bad Den. We will search for it.
And yet something is wrong here!

Even from my own shallow experience, the clypeatus is quite variable in size and proportions, and I suspect that sexual dimorphism can also be detected here.
And if you know about such a method as the twilight collection of ground beetles-phytophages, then you can expect very sensible finds, much more interesting than these dixuses! Look for opportunities!

Vo! Built a collage. So it could be a male and a female?
Ditomuses are also like phytophages? We need a male tricuspidatus, otherwise this species has two Moldovan females and a male Kazakh calydonius. Last year, Carterus dama and Oedesis caucasicus came to light the most interesting of this group of savings lamps. Both types are not listed for Moldova. Plus the usual Carterus ? fulvipes.
You can't zoom out photos in Picasa yet.
In short, I would rather this winter was over. I calculated my strength to wait until March 1, but here it is!
