Good afternoon. Please tell me if there are any illustrations/literature describing the jaws of dragonflies? How they look and work...
A nice find in August this year! Hyles euphorbiae (Linnaeus, 1758) is another new species for Khakassia and southern Krasnoyarsk Krai. Locality is one of the classic gathering places of V. D. Kozhenchikov, which he calls "Ridges". August 11, 2020. Southern exposure of the rocky hill, far from the village. Fast. mixed grass steppe. The light is quite common in neighboring regions, but for some ...
What kind of beetles? In general, beetles often break off a lot in old age, but this does not prevent them from reproducing until their "last breath". The antennae of stick insects in captivity are often sharpened during molting and partially come off, this does not affect their viability.What's the point of a male stick insect without a female? They don't live long anyway.
It turns out that it is not in the catalog of the Russian Lepidoptera in the 2nd edition in the 17th Russian region, but in fact there it is)?

Thank you very much!!!
Hello. I don't want to create topics.I just got sick of houseflies in the country! Grids are out of the question. There is never any wind at all. High humidity.Velcro doesn't help much. Flies are aggressive and very persistent. Contact sprays are not suitable, so there are many surfaces that can not be treated at all. not to mention that it just won't be enough.The room is dim. Weak light bulb in ...
Can I put it in the refrigerator?

What for? After all, they do not exist in nature. I recently observed my pet praying mantises - I saw another advantage of the faceted eye - it has the same image quality for any angle of incidence of rays (within the angle of view). No need to turn your head or move your eyes. But. as always, permission was brought to the Women's Council: one small object can only see a small part of the video ...

It also seems to me that molting is the main problem of insects. It's about breathing... Let's say we consider the respiratory system of an ordinary honey bee. Through the spiracles, air enters the large tracheae, from there - into the air sacs, from there - into the small tracheae and is then distributed through the body tissues due to diffusion. In this case, the movement of air into the air ...
Dear colleagues, good afternoon!We have good news: the All-Russian conference with international participation "Dendrobiont invertebrates and fungi and their role in forest ecosystems" (XI Readings in memory of O. A. Kataev) was supported by a grant from the Russian Foundation for Basic Research.Now we are preparing documents and finalizing the amount of the registration fee, support measures for ...
Dear friends, could you help me to id Parnassius butterflies? Unfortunately I didn't find any detailed field guide of Parnassius group. In case of you know the species in photo, please write the important features which indicate to species. Thank you for ...
Thank you for your answers.Hierophis, thank you for the link! I saw it here on the topic of topics, but I didn't come across this one. There are a lot of interesting things there that I wanted to hear.

I'm trying to raise two acanthosomatid nymphs (I don't know the species), but I ran into this problem: they don't eat anything at all. I put them unripe berries and hawthorn leaves, leaves and seeds of nedotroga, they never ate, they move very sluggishly. There is cotton wool with water. What to do?
What to bait - it is indicated above, in the light. Moreover, it is necessary to shine on steppe areas, they do not fly far from their habitat. Sometimes they fall into soil traps.
There was a need to start a culture of this firefly for fodder purposes. I used to breed them myself in stickworm scraps and excrement, so I thought it would be easy. I put some dried oak and raspberry leaves in a bucket, started up some butterflies , and they died in a few days. I repeated it several times , and the result was the same. No caterpillars were found in the substrate for two months. ...
Good question! The answer depends on the type and age. Besides, I didn't take any measurements, I can only estimate by eye. But in general, the answer is simple: it is better to overdo it than vice versa. It should be noted that only very few species can feed on dried grass for a long time, and even for them the losses will be many times higher than when feeding with fresh leaves. You didn't say ...

Wow, you guessed it! With your consistent approach, everyone will die. That's how you managed to create a puddle at all?. Had the stern willow barrel turned over?The message was edited INO-11.07.2020 01: 48
Well yeah And why do they need water if they are flies - and I also clarified what was meant - whether these are water larvae, like dragonfly larvae for example, or just a dung heap is enough. But you chose to raise the price in the subsequent discussion.I read about the zoofauna of these lakes that I found. So, if you believe the article, then it is in a similar nearby salt lake that there are: ...
Well, I told you as much as I could, based on the experience of the peacock's eyeThis post was edited by Insect88888888 - 07/08/2020 23: 49
Overturned a bottle with a feed plant.
If the subject of our interest is the scientific knowledge of the author of the publication, then this is true. For example, images of homunculi inside sperm cells can tell a lot about the views of preformist animalculists. But if the focus of our interest lies in the field of animal morphology as an objective reality that does not depend on someone's knowledge, ignorance, visual acuity,artistic ...
I try to use the freezer whenever possible. On long trips-primarivayu ethyl acetate.
Idaea politaria
The absence of a red line on the abdomen is confusing. However I guess it is this species.
Whatsapp, of course, is available.
It is immediately obvious that the author has never seen a live stickman.
A difficult case. If it was Europe, it would be a representative of the genus Crassa, most likely unitella, but this genus does not exist in the Asian part of Russia. There is another similar species in Japan, Pedioxestis isomorpha Meyrick, 1932, but it is not found in Russia. Three possible answers: 1. Invasion of the European species on the Russian Far East. 2. A new species for Russia ...
Corrected data. → Parasemia plantaginis.
Figured it out)) These flies are from the Milichiidae family, keep close to predatory arthropods, mainly spiders, catbirds and predatory beetles, and feed on hemolymph flowing from the wounds of the victim
Pyrgus andromedae in the Vologda region? This is what the caterpillars develop on there? But P. centaureae may well be. So it is correct that the dubious is filtered out!Now that you've noticed it, the indication looks questionable. Apparently, the magic of names had an impact. After all, when you read, for example, the list of lepidoptera of the Basegi Nature Reserve of the Perm Region compiled ...
Length 2-2.5 cm, backside with two horns (like crickets)!
Miner specialist Natalia Kirichenko writes:Good afternoon!Indeed, mines can be similar to those of the oak broadmint moth.However, it is a sawfly. I registered a mass of similar mines in Omsk several years ago. I subjected the samples to DNA barcoding and identified them as Profenusa pygmaea.Larvae (false larvae) in the photo on the forum-before pupation-the scutes on the thoracic segments are ...

This species is identified correctly.
Colleagues ask for help with the collection of hawthorn Aporia crataegi L. (Lepidoptera: Pieridae):We are very interested in samples of hawthorn imago from any geographical location, for any years. The samples are necessary to study various aspects of wing morphological variability within the wide range of this remarkable pest species!There is a minimum sample size of 25 individuals of the same ...

So it's just a working major. Batka won't help.Eggs could have been left behind from past times and not be noticed by you. They can also be laid by workers, but only forage ones. None of them are hatched and fed. Besides, since we're talking about reapers, are you sure they're eggs and not crushed seeds with mushrooms?The message was edited INO-02.06.2020 01: 46
Here, for example, such almost without rounding made. Size 41x16.
Dragonfly larvae hunt mobile prey. Dead bokoplavov, respectively, it is not food. The "unknown thing" that started to "stick out" is the so-called mask. Simply put, its jaws, which it grabs prey. Usually they are tightly pressed and not visible. You can watch a video on the Internet about how she hunts. The mask began to stick out, most likely because after death, the muscles relaxed and nothing ...
