What can swarm now?

Community and ForumInsects biology and faunisticsWhat can swarm now?

Helene, 01.11.2005 15:06

I can't figure out what kind of insects are flying outside my window (at the second floor level). confused.gif
Since autumn ended prematurely in Moscow (the temperature dropped to about 0), some small insects have flown out en masse. They fly in a swarm ("jostle") in the crowns of apple trees and slightly higher. The swarm is very dense, moves up and down, and the insects inside it move very quickly. I wanted to collect it, but I couldn't even see it: they don't go down to the ground, they don't fly closer than ten meters to the balcony.
I understand that the question is very vague, but maybe there are versions?
Now they still fly, although there are much fewer of them.

Well, Diptera some smile.gif

Well, Diptera, and I understood (at least 90 percent sure-on the flight, the membranes do not push so much), but what are they? Not mosquitoes, exactly - too fast.
There aren't many late-autumn insects in general, so it's interesting... smile.gif

Well, Nematocera smile.gif
Maybe Mycetophagidae of some kind. I don't know if they're really swarming or not.

The day before yesterday, in the north of Moscow, I saw some small (1-1.5 cm)weevils swarming - either Tipulidae or Limoniidae. Unfortunately, I couldn't get a close look.

No, I was clearly not a weevil, the flight is not the same. I say-they flew too fast. The whole crowd is very dense and moves up and down, right and left. And inside the crowd there is a direct Brownian motion smile.gif

I saw a similar "Brownian motion" in early October. At an altitude of 15 meters, similar dense clusters flew in the crowns of poplars. In general, our activity is still quite high, now only bees are not swarmingsmile.gif, some butterflies are flying, some plants are blooming, in general, a long warm period has turned out.

We had a strong cold snap with a significant minus and temporary snow cover. Most of the late autumn insects did not survive it, although on November 5 I saw and collected some cicadas (as soon as I collect them, I will scan and post them).
And those mysterious diptera seem to have disappeared. Is this really what you saw in early October? I just didn't notice them in the early fall because of the foliage?
Although there were still plenty of leaves when I noticed them. The connection was really viewed: the first freeze - and they appeared smile.gif

Cold snap on November 27-31? yes, we also had this, but the truth did not fall below zero even by morning even once.
And the insects in your case could be caught! With a window net to wave - and all, and it would be possible. It was interesting to me then, too. what kind of "mosquitoes" are rushing around. and from the bottom it looks beautiful, not for nothing is there information that is sometimes taken for" flying saucers "smile.gif

October? wink.gif

I said in the original post that they did not fly up to the length of the net! smile.gif

Oh, right, October, sorry smile.gif
And as for the net, you could throw it at them, for sure someone would get confused!

For a good ten meters?! Well, you're a thrower... cool.gifI can't do that!
Yes, even if it was closer, the net is likely to hang on the tree - get it out later... wall.gif

It is necessary to tie a net on a fishing rod, well, or a bunch of sticky paper for flies...
And rather, before winter begins: -)))

10.11.2005 14:43, Helene

No, it won't work. I once tried to extend the net so that I could get the ribbon that was sitting on the trunk (I wasn't sure. that it's just nupta). What happened was exactly what would happen if you just threw the net: it just hung on the tree (the connection to the stick fell apart), then they started pulling it out. As luck would have it, there's still a tree that you can't fit in.
And those insects are no longer visible, although it has warmed up... Maybe they're frozen out, but most likely they're just short-lived. I posted the question without a scan of the subject only when my hopes of collecting it almost disappeared...

PS With some delay, I myself remembered about the distance - that there was not 3 meters, but all 10. It's like in the joke about the commander at the exercises, who asked a subordinate what kind of battery did not shoot:
"Well, there were a number of reasons... First of all, the shells didn't arrive..."
"Well, then the second one doesn't matter anymore!" smile.gif

Oh, I know! These are bees. Only Australian ones. Or South American ones.

I think these are mosquitoes from the family Trichoceridae, or winter mosquitoes. They are quite common for such temperatures, and constantly form swarms.

Did they? smile.gif But they didn't really turn out to be "winter": they didn't live to see the real winter, and I read that they can fly right over the snow (at slightly negative temperatures). Or are they just short-lived?
