Dear colleagues! For histological and cytological analyses of the Colorado Potato beetle, please tell me which fluids should be used immediately after collecting insects, so that later they can be manipulated (autopsy, fixation, etc.). And is Buena's fluid now used in practice? Thank you in advance.
Hmm, but this is interesting: after all, the ancient Greeks called hermaphrodites what we call gynandromorphs.

The Eupelmids (Eupelmidae) are a relatively small family of chalcidoids (850 species and 45 genera of the world's fauna). The fauna of Russia is insufficiently studied.It is characterized by the presence of a long thick spur on the middle paw, probably serving for the jumping function, as well as a depressed mid-spine in females.Biology-internal and external parasites of larvae of Orthoptera, ...

A beetle in the family Cleridae. It is often found on flowers or tree bark. They look very much like ants from afar. Mottled beetles are medium-sized beetles with a large head and 11-segmented saw-toothed antennae. Mottled birds are bright in color, with multi-colored transverse stripes on the elytra, and the body is covered with hairs. Larvae predate under the bark, develop at the expense of ...
Ant reaper in a test tube (soldier). In the anthill, soldiers act as guards, but their powerful jaws are also used to grind grains.
I know that the flies don't need a knife I meant that such thick thighs make a fly look like a bee with a leg. And what is the long truth really? By the way, I read that some murmurs specifically vibrate the hips, visually thickening them... Is this really the case?About the uselessness of the legging-how to say. Of course, there are brushes and areas of fluffy hairs on the legs (especially the ...
In general, it is interesting whether the cause of death of males is irreversible physiological changes or "psychological moments" such as refusal to eat...It is clear that "psychological changes" depend directly on physiological ones. But still, feed it, inject glucose there, etc. it is impossible (to exclude these crazy moments)?
Wow, what a visor she has! Is there a separate photo of the wing?Awesome lioness. I understand excited dipterologists; -)

2 AdamovIt might be worth looking at this article:Acorn J.H., Ball G.E.The mandibles of some adult ground beetles: structure, function, and evolution of herbivory (Coleoptera: Carabidae).// CANADIAN JOURNAL OF ZOOLOGY 69(3) 1991: 638-650, illustr.Inofrmatsiya extracted here:http://www.zin.ru/Animalia/Coleoptera/rus/car_res.asp
a couple of days ago I saw pieces of paper with advertising lying around the entrance, maybe someone climbed.. It is necessary to call the post office, ask that they do not bring it, but only inform you about the letter
Can you report us there? Really LiveJournal is more convenient than the forum...no, of course, the forum is more convenient. just in LJ there is a delivery of information "at home" but on the forum it is easier to navigate, search, store, etc. and there is a lot more here than there.
I read about the tachina parasitizing the larvae of the larch barbel in Rozhkov's book. So, in principle, nothing surprising. Although it would be interesting to know the method of infection.
It is not necessary to transfer eggs to the plant, these caterpillars will crawl over themselves, the plant should certainly be nearby.Wait until they hatch, depending on the temperature.But the eggs must be fertilized, often in captivity butterflies lay unfertilized eggs. So it may not hatch at all, and you can wait a long time...
Only you misidentified it, it's Psyllobora (Thea) vigintiduopunctata.Subcoccinella vigintiquatuorpunctata I took off about a week ago in my garden:Their drawing varies, but the background is brick, plus hairiness.
This is not Aeshna cyanea - you have Aeshna affinis in your pictures. They differ in size (the affinis is smaller), breast color, and anal appendages (in the male cyanea, the upper anal appendages at the tops are clearly bent down).And the pictures are wonderful!Thank you very much.
In antlers, the anal opening has the form of a longitudinal slit, while in the stag beetle, there are two bare oval spots on the sides of it. In lamellar sawyers, the anal opening is three-rayed or transverse. Unfortunately, the angle of the photo does not allow you to see the end of the abdomen...
Here is an article in English on fishing for light, there are also instructions for making a simple trap.I bought myself a ready-made "Robinson type" from them-I can't get enough of it. I doubt, however, that they ship abroad.http://www.angleps.btinternet.co.uk/guide.htmAnother advantage of the traps discussed there is that they do not kill the catch, after accounting, you can freeze the ...
Skint, if anyone knows plz links to the entomofauna of the "Kem volost" in general and the Solovetsky Islands in particular.
I invite people to join the discussion in the topichttp://molbiol.ru/forums/index.php?showtopic=90116the moderator is kindly requested to post this on a separate topic
I wonder how many people collect butterflies for science and for sale! Intresno also why butterflies suffer.
Polyxena-Zerynthia polyxena (Denis et Schiffermuller, 1775)== Zerynthia hypsipyle SchulzeFamily Of Sailboats-Papilionidae.The butterfly is medium-sized, with a wingspan of 40 to 55 mm. It flies from the end of April to May, the flight in most cases is slow ," not sure", in cloudy weather and if the sun is hidden by clouds, it immediately sets, takes off when worried, usually not willingly, lets ...
Can I carry fuel for primus?Of course! With the import of gas cylinders, gasoline or whatever else can be used as fuel, there have never been any problems. Neither in Ukraine, nor on the way to Uzbekistan. People with backpacks, ropes, and cats are treated differently. The more civilized you look on an expedition, the more complaints you get, and a crowd of smoke-smelling, ragged tourists with a ...
It flies in May and June along the edges and clearings of the forest, in gardens and parks. It flies well in the light. Eggs are laid in 1-2 pieces, less often in groups on the underside of the leaves of the fodder plant. Forage plants - plantain, dandelion, yarrow, ashberry, strawberry and other herbaceous plants. The caterpillar overwinters. Caterpillars appear as early as the end of March. ...

Just keep in mind: the photo is not an adult, but a larva of the last age. One can see the arrangement of wing rudiments characteristic of the last two instars of erect-wing larvae: the rudiments of the anterior pair are covered by the rudiments of the posterior pair of wings.This post was edited by PVOzerski - 04/24/2006 12: 58

I made her crawl properly!http://www.ibiblio.org/e-notes/VRML/blaxxun/caterpillar.htmtrue, I don't really like that butterflies don't flutter (like their friends outside the window), but fly like hefty birds
Come on, the pubescence is very different (the male is fluffy, otherwise you can not say). And at the end of the abdomen, their primary sexual characteristics are clearly visible. And if the female has already mated - so there is finally sfragis.
It is very similar to the glaucus-Tiger swallowtail. It is difficult to say for sure, but judging by the fact that the butterfly is quite common , it is true. In Virginia (which, as you know, is very close) this is the most common sailboat.
The Helenesubspecies is allocated to Stephens. According to the Japanese, the subspecies geisha lives only in Japan. And as for the differences - so everything ultimately rests on the structure of the genitals! Here I have no information.
Idea leuconoeIts habitat extends from southern China and Malaysia to the Philippines and several Indonesian islands. The butterfly flies in the thicket of tropical rainforests. The caterpillars develop on the tylophore. The wings of this large Danaida reach a span of more than 15 cm. She flaps slowly, as if in slow motion, because of the size of her wings. Birds avoid the butterfly, because it is ...
Try to swat the fly and make a slightly sharp movement with your hand - you will see how it does not see. Maybe, of course, the hairs will smell the fluctuation of the air. In general, animals with faceted eyes see moving objects better than those at rest, because when an object moves, it passes through a large number of facets at once. There is another feature of faceted eyes - they are good at ...
