Acanthoscelides obtectus?

Yes that's more correct

zernovka to see-Bruchus sp. - what are the options for beans and peas - were there any outlets in what quantity?

Can I try to withdraw them?

the beetles did not have time to come out, and so it seems that several flight holes are planned-I am for the bean seed Acanthoscelides obtectus

the adult larvae died and became mummified. it remains to gnaw through a thin circle of skin to the beetle when leaving.

See if you can spot a weevil?

What do you mean, it won't work out anymore?

26.03.2010 2:54, omar

from such larvae, which are not in the photo. maybe there are other larvae still alive in individual beans. Do these corpuscles show signs of life?

Staphylin was caught in a pine tree with an admixture of birch. 11-12 mm. The front legs are extended. The head and pronotum are opaque, densely dotted. Top with a metallic blue tint, covered with rather thick adjacent hairs on top. The legs and base of the antennae are red.
The lateral edge of the pronotum bends anteriorly to the bottom.
The mandibles are smooth, without teeth.
As a variant of Ocypus compressus, maybe such a Velleius…

Yes, these did not seem to be spinning... There are about a dozen grains. Maybe it's worth a try? Or poke around and check it out?

2akulich-staf is definitely not Vellius, it is rather someone from Ocypus or Staphylinus (sensu lato) as in "green". In general, the beetle should be washed, at least in diluted alcohol or vodka...

yes, I just pulled it out of there, it looks like it's in tar. I'll try to clean it up.thank you

I will assume that this is Platydracus fulvipes

27.03.2010 9:03, akulich-sibiria

I understand this kind is not in green...so I didn't have the opportunity to find it myself, thank you, maybe it has synonyms or it was previously called a different genus?

27.03.2010 11:33, Dmitry Vlasov

It used to be Staphylinus fulvipes... In the "green" is. I'm just not sure about its habitat in Siberia, M. B. there is a close species...

People!!! Help!!! I can't identify the Malaysian hornbill. It was brought to me 20 years ago. A relative "stole" it from a souvenir factory in the ROC of Kuala Lumpur( according to him), where they were taken on a tour. That is, it can also come from the island part of Malaysia.. I went through a bunch of sites with images of horns, not even lying next to them... Interestingly, the beetle has completely atrophied oral organs, even the palps are located under the mandibles. Length 48 mm (with mandibles).

Elizar, the hornbill is similar to Dorcus curvidens. In any case, my instance looks very similar, although it is from Filipin.

Yes, he seems to be the only one in the Palearctic so blue-red-legged.

Staphylin IMHO in a warm (90 gr) turpentine is necessary to remove the resin. Just don't start a fire

More precisely, it is now called Dynodorcus curvidens (Hope, 1840)
In general, a lot of people like...for example, it reminds me of Aegus (Aegus) sp.

It looks like A. (s.str.) parallelus, yes.

Here is what is said in the book Lucanidae of Thailand (unfortunately, the table of genera is not there) про Dynodorcus curvidens:
"Head with carina between canthus and base of the mandibles"

About Aegus, I can say that this genus is characterized by completely separated eyes (based on the same book).

According to the roaches of Yu-In Asia, as I understand it, the main work: Arrow G. J. The fauna of India, Including Pakistan, Ceylon, Burma and Malay Peninsula. Coleoptera, Lamellicornia, Lucanidae and Passalidae. 1950. 274 pp.

Ouch. These entomologists are such entertainers. This is how vodka is used unconventionally....

We have spring already on the threshold, the willow has bloomed, I think the first apids will soon fly. Andrena, too. I think I'll catch more of them now, and send them to you for identification. By the way, can you tell me what is better to put in the stains? They say ethyl acetate is good..where can I buy it?

27.03.2010 23:01, omar

I'd say it's Smaragdina

embarrassing spot in the middle of the pronotum. AND the posterior corners of the pronotum are raised, the truth is poorly visible on the pronotum. But you need to check it, I'll look at it at work mandatory

Dear experts,
I ask you to help identify these babies at least up to the genus.

7 mm

And why does the spot bother you? It's common for this kind of thing to happen. Alternatively, Smaragdina affinis. Take a look here:

Regarding #2, I agree, Margarinotus brunneus,

but according to No. 3, look, the front shins are quite different.

I ask the specialists to take a closer look at No. 3, at least until the end.

Thanks
