Identification of Hymenoptera (wasps, bees, ants)

Thank you very much! This is my daughter's summer project. We thought it was simple: caterpillar, cocoon, imago. But it turns out... I don't understand, so the rider's larva started pupating in the babbler's body?! Do these balls on the nettles have anything to do with the rider? I just don't understand anything about insects, so so many questions

Thank you very much! This is my daughter's summer project. We thought it was simple: caterpillar, cocoon, imago. But it turns out... I don't understand, so the rider's larva started pupating in the babbler's body?! Do these balls on the nettles have anything to do with the rider? I just don't understand anything about insects, so there are so many questions

The rider laid an egg in an egg or larva (I don't know exactly how in this species) of a babbler. The babbler larva (with the rider larva inside) grew and pupated, after which the parasite killed its host, underwent metamorphosis, and emerged from the cocoon made by the host larva.
Most likely, the murmur is not directly related to the "balls", or galls (see fig. acc. Wikipedia articleAs far as I know, there are no gall - forming plants among the babblers, although some species are miners-they live inside plants and make moves in them without causing specific growths (galls). But this species was not a miner, as can be seen from the pupa, as well as from the fact that this group of riders does not have special devices for infecting secretive hosts. Most likely, the babbler larva on nettles fed on small insects (most of the sirphid larvae are predators), among which there could be gall-forming ones (some aphids, etc.).

Thank you very much, now everything is clear.

Thailand, October. I'm not sure it's a wasp. She moved her belly quickly.
The size of a couple of centimeters probably.

Ampulex sp. [Ampulicidae]
I won't even try to get to the view from images of this size, and I don't use social networks in principle.

Thanks to the slightly enlarged images that show red thighs, it is possible to say with a high degree of probability that this is a widespread Ampulex compressa in the tropics.

Please tell me what kind of riders they are. They were found in the Moscow region.

I'd say it's the Xylocopa valga carpenter bee.

But some important signs are not visible, so for a more accurate definition, try using the key that "hangs" on the 42nd page of this forum (URL #2079).

No, the comparison doesn't fit. The upper image (X. valga) shows the antenna of a male, while the lower image (X. violacea) shows the antenna of a female.

The proportions of antenna segments are very different for different sexes. In this case, as often happens, the 3rd segment of the female antenna is much longer than that of the male.

Still, try to compare the pads on your hind legs using the key I specified.

Similar to Anthidiellum strigatum.

The first two are correct. However, little is clear.
This pad is slightly outside on the back side of the hind shins. In fact, it is clearly visible, since it occupies from a third to half the length of the lower leg and is not covered with thick hairs, unlike the surrounding surface.

Please tell me what kind of riders they are. They were found in the Moscow region.

In the 1st photo, the same rider as in the post dated 17.08, to which I replied on the previous page -
" Perhaps in the photo Limerodops elongatus (Brischke, 1878), respectively Ichneumonidae, Ichneumonionae. Pretty similar, anyway."
In this photo, he looks even more like him
in photo 2 - some cryptina (Ichneumonidae, Cryptinae)
in photo 3-Pimplinae, maybe later I'll look at it, compare it... There would be time.

Not strong in riders, I will assume Enicospilus sp.

Yes, this is Enicospilus . To determine the species, you need to see the front wing (venation and sclerites in the discocubital cell). It would not hurt to take a photo of the head strictly in front and in profile and the claws of the hind legs/
Try to insert a small white piece of paper between the right and left wings when shooting (so that their images do not overlap)

And this is Ophion obscuratus F. (Ichneumonidae, Ophioninae)

M. O., Topoliny,23.06.2014

1. This is something like Sympherta sp. (Ichneumonidae, Ctenopelmatinae). Do you know who it infects there?

2. In my opinion, a male Cerceris ruficornis (Fabricius, 1793) from Crabronidae. If you made a mistake, AVA will correct you

Yes, he is the one.
Only the name is correctly spelled differently - Ph i lant h us triangulum.

Thank you. wrote from memory, which is subvela

Thanks !

Hello! A 2.5 - 3mm wasp emerged from a yarrow stalk, probably a parasite, a week ago (25/10/14) under laboratory conditions (in a Petri dish), Saratov. On the Forum for the first time, please tell me how to properly take photos of the OS. (I shoot under a microscope, there are difficulties in positioning the wasp)
