I have a few questions that probably will seem silly to experts and just amateurs, but they seriously puzzled me. if someone answers them, I will be very happy smile.gif
1. on large beetles I often see small insects like fleas, who are they-parasites or symbiotes??? and what do they do on beetles?
2. in the flower garden, the leaves of roses and some other plants are cut in semicircles-I thought that ants were cut for mycelium, but not-wasps (bees?) carefully cut out the semicircles and take them somewhere. Why do they need them?
3.a hole appeared in the old board - about 6 mm in diameter, and piles of shavings under it. When the noise comes from the burrow, an angry buzzing sounds can be heard. I began to watch - a bee crawls into the hole with a businesslike look - a large shaggy one. and it continues to expand the apartment-shavings are constantly pouring in... Who is it???
4.there are several wasp nests in the attic. but I've never seen them before - black ones with thin bandages of yellow on their bellies, and slim ones with big eyes. I wonder what kind of view. and they are not as aggressive as past neighbors-bright yellow large wasps, at least these have not bitten anyone yet over the summer...)))

1.
Parasitic mites. Like this, right?

2.
Solitary leaf-cutting bees (Megachile spp.), they use them to build cells in which their larvae develop:

3. Some kind of bee. If large , it may be a carpenter bee (Xylocopa sp).:

4. Judging by the description, the wasps are Pelopean (Sceliphron sp.). Spider Hunters:

Small insects on large beetles are usually ticks. They're parasites.
These are megahila leafcutter bees. They need leaves to build their nests.
Describe the bee better. The tree can contain many genera/species of bees.
these are probably some solitary wasps - look at what insects they bring, then you will see who they are.

And then I didn't have time weep.gif

kotbegemot, ticks are exactly like that... parasites, after all. Well, I suspected as much. poor beetles.
2. singles? this is how many of them I have, all the bushes are cut )))
3. the bee is similar, but popushistee slimmer and lighter. Did she decide to make a nest in the burrow? or just live?
4. no wasp is different - not with such a thin waist bandages on the abdomen itself. caring - the horror is ventilated all day, the nest is rebuilt and they don't pay attention to me, they even sat down a couple of times (I have a phobia for wasps) and despite my wild reaction they calmly flew away.

thank you so much for your answers smile.gif
if it wasn't for the internet I wouldn't know who's who until the end of my life smile.gif

omar, solitary wasps? but they have large nests, one with a diameter of 30 cm, the second is slightly smaller and they collectively take care of the superstructure. or do insects have loners - this is a special concept?

30.07.2008 8:52, omar

No, so they're not singletons. I just wasn't aware of their nests.

30.07.2008 8:59, omar

Then it's probably the polist wasps. Look at the photos in Google - aren't they?

30.07.2008 9:00, omar

The bee can hardly be identified by scripture - it's better to take a picture

I'll try to catch her, but she's careful...
very similar to this one http://molbiol.ru/pictures/pakor_020.jpg true, there is only a full face - but it is very similar - the same fluffy
os and I found it from the picture http://im5-tub.yandex.net/i?id=49462677&tov=5 or http://foto.academ.org/details.php?image_i...6a7e7c71511b95c
That's the insidious type smile.gif

wereps really not aggressive, or was it just my luck? you can leave the nests or you should still remove them - we just have small children you can't explain to them-that these are not flies and they don't need to be chased. if you remove it, how?

30.07.2008 11:00, omar

To be honest, in your photo, wasps of the genus Vespa are always aggressive creatures and do not allow anyone to approach the nest

They make nests to hatch larvae in them smile.gif

I still think that these are polysts. Are their whiskers black or orange?

30.07.2008 13:36, Verunia

I take a photo on the weekend of the os, if it turns out, then I will also watch the bee...)))

1.
Parasitic mites.

Small insects on large beetles are usually ticks. They're parasites.

As far as I understand, these aren't usually parasites. These ticks use beetles exclusively as transport -

Gm. So many times I saw ticks digging into the body of a beetle - they did not run on it, they just sat motionless, digging, and did not pick off even with a fingernail. Many remained on the body of an already dead collector's item. It's a strange journey. confused.gif

Um. So many times I've seen ticks dig into the body of a beetle

+1, same thing observed many times.

+1, I've seen the same thing many times.

Just because ticks hold on tight doesn't mean they're parasitic, but rather that they don't want to accidentally "fall off the bus." And the fact that they do not run away from a dead beetle, rather says that they do not use it "for food" (and do not understand that it is dead), but patiently wait for it to crawl/fly to the manure, for example. But I won't argue, it's just my opinion.
There are also parasitic mites on insects. The ones I saw were red in color, and insects that have at least one tick on them are often more sluggish (they are much easier to photograph).

This is called phoresia – the use of insects as a transport for settlement... often it is not adults who phore, but nymphs, who do not even have a mouth apparatus, but have suckers, precisely in order to stay on their "transport", this has nothing to do with parasitism in most cases, although there are parasitic species, of course, and often both are combined...
