Isn't it a ground beetle? What kind of basins?

19.11.2005 14:32, andr_mih

Cylindronotus anything

I don't have a bug, just a photo. 3-4 mm, under the oak bark.

Both photos of the same beetle or not,
It's definitely not ground beetles or Cerylon. It is difficult to determine, because the photos are not very clear. According to O. L. Kryzhanovsky: "If the beetle is unknown, it is most likely a black calf..." And another question - where was it filmed..?

25.11.2005 18:38, гость: Дзанат

Filmed in France. According to the photo, I think these are two different beetles, but I can clarify. What is not Cerylon, I understand. In general, the question disappeared, but I'm interested

It was important to know whether they were entomophages or not!?

26.11.2005 8:33, Dmitry Vlasov

To Dzanat
If the beetles are French, then the exact definition is already more difficult. If only: Moscow, Ivanovo, Yaroslavl... here it would be possible to estimate by selection. In general, it is a thankless task to determine such a trifle from photos. There are so many of them.... Here you can't determine the stasis from the beetle...
About entomophagy or not-rather no than yes. Apparently both beetles are black-bodied. and among the crustaceans in this family, the majority are saproxylomycetophages.

Thank you, that's how I answered people

On Sunday, when the sun warmed up, I found this animal on the windowsill... Can you tell me who it is? The original size is about 5 mm...

This is a skin-eating beetle of the genus Anthrenus. Beautiful, but the pest is still the same.

This is the motley leatherworm Anthrenus picturatus, brought to us from Central Asia or the Caucasus. Now one of the most dangerous types for stuffed animals, feather products and wool.
Apparently, the beetle just hatched (usually it starts flying later - in April - May), and it came to the window not to warm up, but because it has a positive phototaxis (it flies to the windows).

The first caterpillar, not big 1-1. 2 cm. Found in a flower bed: tulips, Sep. Help me determine it. In daylight, the color of coffee is with milk. Pykha shines through the body, because of this went to red.

It's the larva of a bug. Not a caterpillar.

This is definitely Harpalinae, most likely Ophonus sp. , or Harpalus sp.
Only here with the size is a little unclear. The spread is too large. Most likely, you've seen different views.

Harpalus affinis Schrnk. or distinguendus Duff. the female. Aren't there any bigger photos?

13.03.2006 22:13, Bad Den

14.03.2006 0:04, BO.

No, this is neither Harpalus affinis Schrnk., nor H. distinguendus Duff., they even have a different color. I am inclined to believe that this is not even Harpalus (s.str.) sp. Most likely, it is still from the genus Ophonus Steph. Still would know where the bug is caught and the size.

Astrakhan region. In the garden . In a stack of tiles

, there were two beetles 0.8 and 1-1.2 cm at once . Now it is often found: under the foliage of apple trees, under stones, etc.

They are smart, this one is the most successful.

This is Badister sp.
I take it you have it caught and available?"
I can send you an article by Komarov on this topic:

No, it's still Harpalus sp. but which one? In the south, there are quite a lot of metal-colored species. Similar, of course, to . affinis, especially since their variability is huge...
Ophonus does not "pull", they have pronounced hairs on the pronotum and elytra, here they are not visible.

No, only last year's photo is welcome . Thanks for the definition.
If you can add an article to the soap bo@bov.com.ru , very much by the way.

14.03.2006 22:59, Bad Den

Hairs on the ndcr. just the same are viewed - in the form of a slight "dustiness".

15.03.2006 8:42, Dmitry Vlasov

To Bad Den
Yes, no, it's rather not hairs, you can't see where they "grow"from. In ophonuses, these "pores" are clearly visible. This is a female, and they are matte in contrast to males, so it seems dusty...
AU-professional ground beetles!!! Resolve the dispute.

You're confusing " hairs "and"bristles". The bristles actually sit in the bristle-bearing pores, of which there is usually a strictly defined number and location (this feature is used in diagnostics).

The article still has a hitch.
I thought I had it, but it turns out I haven't scanned it yet. If I scan it, I will definitely send it to you.

To Bad Den
Sorry, I chose the term somewhat incorrectly, but if you noticed, I put the term pores in quotation marks (although only in the second case).
The hairs of Harpalins do not "grow" in a bare place, there is some kind of dotted line on the surface - "pits", or whatever you want to call them. Even in very old and "bald" specimens of H. affinis, punctuation is visible on the outer spaces of the elytra.
In Ophonuses, the dotted line is clearly visible both on the elytra and on the pronotum. there is no such thing in the photo.

16.03.2006 10:45, Bad Den

Even in very old and "bald" specimens of H. affinis, punctuation is visible on the outer spaces of the elytra.
In Ophonuses, the dotted line is clearly visible both on the elytra and on the pronotum. this is not shown in the photo.

The photo doesn't show any dotted lines in the outer spaces of the idcr. - out of focus. So it is impossible to tell by this sign whether it is Harpalus or Ophonus.
But! In Harpalus (s. str.), there are no hairs (not setae) on the ndcr disk.

16.03.2006 11:43, Dmitry Vlasov

To Bad Den
I know the difference between bristles and hairs, as well as what are the bristle-bearing pores.
By the way, it is also not clear whether there are hairs on the elytra disk, but rather the "dustiness" that you saw is the" reflection " of the flash from the microsculpture of the female. Moreover, in Ophonus (s.str), the hairs are still very well expressed on the pronotum disk, and it (the disk) is covered with a rather thick dotted line, but here it is not visible.

Harpalus distinguendus Duff. female-I apologize for affinis, I looked at something wrong, look at the 2nd segment of the antennae-it is 3/4 darker from the base, affinis can't have this, and even about Afonus here completely past

20.03.2006 22:41, BO.

Help me determine: the spider is not large ~8 mm, the second animal is about
1 cm-the larva of an earwig ?

Larva - IMHO, bug-like. It doesn't look like an earwig at all.

21.03.2006 16:10, RippeR

Exactly, the earwigs have larvae the same as the earwigs themselves (almost, I don't know us all..). This is zhuchinnaya, and whose exactly... maybe a nutcracker of some sort, although it looks like a predatory larva.. It can be seen that she is crawling on the sand, maybe something like a horse of some kind, got out of her hole..?

21.03.2006 17:21, Bad Den

Ground beetle larva - 90%
And here's what... It is very similar to Cicindelinae...

21.03.2006 19:50, RippeR

Let's ask Bo, where was the photo taken? For me, this is more likely campestris, since it is most often encountered..

21.03.2006 20:03, Bad Den

Most likely in the Astrakhan region.
