insects are also present in winter. information about wintering grounds, how they hibernate, and in what condition is very important for understanding the ecology of insects. They winter in very different places - some under the bark, some in the litter, cones, fruits, in the ground, at the bottom of reservoirs, in people's homes, migrate to the south. Some insects are generally active in winter - there are beetles that swim under the ice.

So it depends on what/who you want to find.

13.12.2006 16:46, KingSnake

Well I do not know... Who do I want to find? Someone...
I just want to give it a try... At the university, they were taught only to collect insects in the summer. You can't go out with a net in the field right now....

Where should I start, so to speak, for the uninitiated?

13.12.2006 21:09, RippeR

I'd like barbels, weevils, goldenrods.. where to search?

Where and how to find pupae in winter?

Where and how to find pupae in winter?

Wintering cocoons can be found at the foot of trees, on branches. Pupae of mace-whiskered butterflies are easy to see on different fences. In hollows, crevices, look, be sure to catch someone.

By the way, the term "winter gathering" takes on a different meaning if it is held in a warm, tropical or subtropical country during a winter time that is "unpopular" with entomologists. This way you can collect a lot of new information.

14.12.2006 8:42, KingSnake

Hm... I'll have to see it. Can you find anyone in the garden (apple trees, cherries, etc.)? In summer, of course, the species composition there is relatively rich...

14.12.2006 11:50, -Дзанат-

Collect the forest floor. I do not know how to do this correctly, but I collected it myself in small packages, then disassembled it. At home, in the heat and light, a lot of things crawled out.

14.12.2006 14:57, RippeR

then he shares the methods of proper litter collection.

14.12.2006 17:57, Pavel Morozov

Leaf litter and all sorts of dust is collected from the top layer of soil and sifted into something like a large sieve.

If you want to find beetles, then the easiest way is to look for them in the forest. There you can find them under the bark of dead trees (mostly xylobionts and some related predators, but occasionally you can find something else). Still very rich fees are given by the bark that has fallen off from the trees, lying loosely on the ground - there are always a lot of wintering insects under it, including beetles, and a variety of different ones, including not even forest species at all. It also seems to me that the method of selecting insects from the forest floor brought home should be very effective, but I haven't tried it myself yet.

There is really a lot of wealth under the bark - especially if this bark is from an old tree, and even from the south side. If the snow cover is shallow, turning over rocks, especially large ones, gives good results.
Well, of course, it is also worth mentioning exclusively "winter" animals. In the forests, on a warm sunny winter day, various mosquitoes, aphids (although the latter are not winter), flies, and spiders come across right on the snow. On the moss you can meet wingless scorpion - boreus. In our mountains, at an altitude of 1300-1700 m, the southern slopes are often without snow in winter, and you can even hear the chatter of locusts, and once I saw some nymphalid flying. And in the manure there, fresh in the sun, life boils. In general, there is no weather in which it would be impossible to collect insects. The main thing is care, enthusiasm and knowledge of biology.

Still, it is better to collect during the thaw-clearing period, at least in our southern Ukraine. It is better to take three oilcloths and a sieve with you. They recommend a soil or special entomological treatment, but not everyone has it, to put it mildly. You can buy a kitchen one, but, alas, it does not like travel-transportation. So, we go to the forest and spread oilcloths. We rake on one litter and manually remove a large fraction and throw it out in figs - there is almost nothing there, everything falls to the bottom. Then we drive the mass that has significantly decreased in volume through a sieve. How many little things there are! Bugs, bedbugs, mites, millipedes. Such makar can sow rot, dried manure, tinder boxes. It is convenient to fold a large fraction on one oilcloth, sort through the material in portions on the other, and kneel on the third. Pay attention to the hay piles! Where the hay is slightly moist, a lot of things accumulate. In open areas, you can successfully disassemble the sod, for this you need a small shovel.

Today I was on the "winter fishing". What I want to tell you.. For our park - land fishing is complete nonsense. I found common ground beetles, woodlice, cockroaches, and common bedbugs. In short, everything is normal, not interesting, just a little and generally garbage. It's a pity, so I wanted to get something interesting..

17.12.2006 11:55, Tyomochkin

And in Moscow, no one went to the woods or parks? I just have no idea who and what is found in Moscow from butterflies!

17.12.2006 12:49, stierlyz

And from what point of view to evaluate the success of fees? If the collector is looking for something big and beautiful - well, then in winter he just needs to go to the tropics. And in our latitudes, you can find interesting from a scientific point of view, but not spectacular material in winter.

it is clear that it is not large. But there are a lot of interesting things among the little things, and I came across one g, although I don't know how interesting those few ground beetles of nebria are, I've already met them in many places - small, so black, with grooves on the elytra and several pits.

17.12.2006 14:27, stierlyz

If you define the material in this way, then there is not much point in collecting it in winter. You have a good specialist in Moldavia - a carabidologist, who can identify all ground beetles in principle.

17.12.2006 22:05, RippeR

Please notify me who? If you're talking about Nikulisyan, I'll let you know that he's gone.. I don't know any more, at least not in Chisinau..

17.12.2006 22:51, Necrocephalus

Today I went to "winter fishing" again. The result is at least 5 new species (because I caught in a new station for myself - I looked at wintering grounds near a swampy meadow). I was especially pleased to find such an interesting (and very effective) beetle as Pilemostoma fastuosa. In my opinion, this is one of the most beautiful shield socks.

2 RippeR: Tell me, do those" nebryas " that you caught happen to have tenderloins on their front shins? If there is, then it is possible, Platynus assimilis, or some similar species. They look really cool like nebria, when I found them for the first time in the forest, at first I also decided that they were nebria, until I looked more closely smile.gif

Did anyone go to Moscow or the Moscow region for "winter fishing" of pupae?

18.12.2006 14:11, RippeR

mine don't have clippings.

18.12.2006 21:19, Mylabris

I got out today, too. On Or. I got caught in a blizzard, but when I went down to the river valley, I stirred up some rocks. But the catch is not very rich - a couple of weevils, one Syntomus and two empusa.

19.12.2006 12:11, andros

I also caught someone I don't know myself , they were hanging in the barn , let's see what happens.

""Did anyone go to Moscow or the Moscow region for "winter fishing" of pupae?""

Last week I scored 5 cocoons in Butovo Forest. Of these, 4 pieces (not determined yet) were found under thick moss grown on birch trees. And the cocoon of Deilephila elpenor was dug up in the litter of a bush at the edge.

20.12.2006 7:52, Tyomochkin

Everything! I'm going to "winter fishing"!!!

20.12.2006 15:17, RippeR

And I only found American women under the bark..

Today I went out on a winter fishing trip again. The catch is not bad enough, although I don't know how.. In general, I found 16 Cucujus, like haematodes or cinnabarinus. Tell pliz how to distinguish exactly. According to the identifier, the keys are strange, I don't understand exactly.. I looked at the photos in the Net - I found differences in pronotum, can they be considered stable? Mine have a more square shape.
I also caught 3 types of black - bodied subcorns-1 brown, another black with a purple tint and 1 small with yellow spots. Well, in general, that's all.

21.12.2006 23:37, Necrocephalus

In cinnabarinus, the mandibles are completely black, while in haematodes, only the tops of the mandibles are black.

I'd love to see some pictures!

Can you learn more about the winter singing of locusts at such heights?

22.12.2006 12:29, Mylabris

What is it exactly? I don't have an oscilloscope smile.gif...
Just some locusts (I don't understand them) on the southern slopes (where greenery breaks through under a layer of dry grass) on hot days (the soil warms up to 20 and above) chirp, sometimes they jump out from under their feet. I won't say that it's massive, but they do come across.

22.12.2006 12:43, Насекомовед

An oscilloscope is not needed smile.gifhere: I wonder what species overwinter at the imago stage (of course, some are known, for example, Acrotylus spp.), but suddenly, something more interesting. If possible, could you take a picture of these locusts and also look at the pattern of their wings (there are dark stripes and coloration, or they are transparent).

Which is small with yellow spots - it can be Diaperis boleti.

But in general, a photo in the studio, as they say!:)

For example, in my opinion, in winter it is not particularly worth walking through the woods, you will not find anything particularly cool,it is better to straighten the collected material for the past summer!Well, if it comes down to it, then it's worth collecting pupae, but the size is bigger!!!

Since the winters have gone very bad (warm), you can collect and, moreover, successfully ground beetles under the bark of fallen trees. Some carabuses are only caught in this way. In the summer, the traps are very tight. But manual collection brings success .For example: C. irregularis. C. intracatus b.

I would like to add : if you are absolutely impatient and nostalgic for the summer excitement of fishing, then go to the forest - to break the bones.

I'll try, maybe I'll get out on the weekend - we have it now +8.
