Urticae and xanthomelas at an altitude of 3000m.

Community and Forum → Insects biology and faunistics → Urticae and xanthomelas at an altitude of 3000m.

I was in Altai this summer.
Question: what did fresh urticaria and xanthomelas do at an altitude of 3000m, where there is snow in the summer, in large quantities?
There are no forage plants nearby.
Do the whole crowd fly so high and why?

And they were there in a span or were they spinning around the rock scree?
Maybe butterflies are looking for favorable conditions for them?

I have observed that hives adore the highlands. They stay on rock scree, and in bad weather they hide in crevices.
Maybe they spend part of their vacation there, like, a high-altitude resort, beautiful views...

Migrations?

In urticaria, this is in the blood - let's recall the alpine Aglais nixa, A. rizana, A. caschmirensis

In Switzerland, on Jungrfraueh saw hives at an altitude of 3500m.

I have seen urticae in Armenia for 2000 years. By the way, Vanessa cardui for some reason loves great heights-in the mountains in the Palearctic there are literally everywhere. I met her at 3500.

Yes, not only urticae and cardui. In the KCR, I saw a mourner on 2800 (in general, a mourner flying together with Apollo - there is something in this..), an admiral on 3000-3100 en masse.

Aglais urticae - 3200 Dolon, Kyrgyzstan.

Tell me, did the admirals migrate?
I observed them at the foot of the mountains in Dombay on rotten apples and pears at the end of September.
It looks like they're flying over the ridge after drinking.
In January, I saw them in the Sochi arboretum, where they ate magonia nectar.

I didn't think so. They were fresh, not quite a flock of them, just a lot of them. It was July.

I also noticed that from 2000 to 3000m there were more hives than at the bottom by 1000-1300.
At the top, they were perfect in quality, but I understand that there is nothing for the caterpillars to eat (nettles do not grow), but for now they would have flown in, they would have been a little shabby. How so, as if they were hatched at such an altitude (I'm especially talking about 3000m), especially 3000 in the Altai, this is not in the Caucasus, much to the north.
True, I now recall that in the Oymyakonsky district of Yakutia I caught xanthomelas at an altitude of 1300, there was just about the same as in the Altai at 3000, mountain tundra.

Their migration takes place at such altitudes. After all, as you know, the higher the safer.

If there was a migration, then the butterflies would move in a certain direction. Sitting on the crest of a ridge, this phenomenon can be observed for several species.
Immediately, the situation, as I understand it, is completely different. Butterflies are born in the middle mountains and rise to the upper belts.
The fact that the higher, the safer, I would argue. There are plenty of insectivores in the upper belts.

I also believe that they did not migrate, because they calmly circled over the rock scree, fed on flowers, and standing at the cliff, I noticed that they did not fly to the neighboring ridge, they were happy here at the prevailing altitude.

At high altitudes, it is safer not so much from the point of view of the presence of predators, but because of the absence of negative atmospheric phenomena.

22.09.2011 16:11, lepidopterolog

Have you ever been to high altitudes?

Negative atmospheric phenomena are plentiful there)

22.09.2011 16:44, niyaz

Depends on what counts as high altitudes? Above the troposphere, atmospheric phenomena are generally absent. But in general, the higher you go, the rarefied the air becomes. Accordingly, the air resistance is lower, the speed is higher, and the energy consumption is lower. Therefore, for example, geese choose an altitude of 10 km when migrating, and specifically, hives were observed at an altitude of about 6 km. At the same time, to recharge energy, they must be powered and for this they take breaks, going down to the ground. Therefore, seeing how hives fly from flower to flower, you may get the impression that they are here all the time.

Butterflies are not geese, and they do not voluntarily climb mountains higher than 6 thousand meters. And in the mountains starting from 1-1, 5-2 thousand oh how restless in terms of atmospheric phenomena
