No, I didn't come across such information. In my opinion, the main difference between this phaeton and the other two types of runners in our country is that it is not only a collector of dead insects, but also an active hunter. The other two species are "imprisoned" for collecting corpses. I may be wrong.

For several years of fragmentary field observations of the steppe runner, I saw mainly that dead insects and even their spare parts (large species) were dragged to the nest, they did not attack the healthy ones themselves, as I did not slip them - the weakened and dying ones were quite enough, I saw from small things that they grabbed live aphids...

Here is a photo on which I put a paralyzed caterpillar with a road wasp to their nest - when I watched the nest, she was looking for a place to hide the caterpillar nearby and was afraid of something, so I slipped it to my wards - they quickly grabbed it and put it in the nest... please note that they are dragged correctly, so this is not the first time...

Kirovo-Chepetsk, Kirov region. June 13.
This rider came out of a swallowtail pupa.

Funny... If the whole process of exiting the chrysalis wasn't consistently captured, I would think of a hoax. It's not a rider! This is a sphecoid oska, and how it ended up in the pupa is a big question.
Unfortunately, I'm not so advanced in this group that I can always keep all the key signs in my head, and the photo doesn't show everything I need.

I couldn't see if there was a stalk of the abdomen, if there was a "horn" between the bases of the antennae, and the venation of the wings. I can't even remember the family name from memory. I hope you still have the copy?" Here, apparently, you should wait for the appearance on the AVA forum, which is more knowledgeable.
In any case, this observation of uncharacteristic biology is very interesting.

Kirovo-Chepetsk, Kirov region. June 19.
This rider came out of a hawthorn chrysalis.

As an option-Thyrateles camelinus (Wesmael 1845), but this is without any guarantee. Too many of them are similar in color and proportions, often in different genera, and sometimes the necessary signs are not visible at all. There are a lot of pictures of incorrectly identified riders on the web, and there are very few specialists in the group

I looked at your site and saw that this rider is already signed there as Cotiheresiarchs virus - this is a clear error. Cotiheresiarchs dirus Wesmael is a representative of the Zimmeriini tribe, which is not numerous in our country (1 genus with 2 species in Europe. parts of the country) will be larger (14-15 mm) and has very characteristic features, such as a strongly bent forward apex of the platypus, a head expanded behind the eyes, a hind foot strongly compressed from the sides, and the absence of mandible teeth... There are many other distinguishing features that are missing from your rider - see the drawings by Alexander Tereshkin that Google search results show. He specializes in these riders, and he (one of the very few) can be trusted in this matter.
By the way, your photos with the wrong definition are already there too, introducing additional confusion

There was another question: why do you have a rider in one case shot next to a hawthorn pupa, and in other shots he is sitting on some kind of cocoon? It's the same beast, isn't it?

In the next post, some cryptina (Ichneumonidae, Cryptinae), you should not even guess from the photo...

I'm not an entomologist. Just an amateur amateur.

Since you don't always get an answer here, I started posting pictures on the site as well. http://www.diptera.info/forum. There I got this message definition. Of course, I check the definition with pictures on the web and saw the drawings of Alexander Tereshkin, but since I have never been an expert, I did not notice any differences.
I deleted the wrong names.
Cocoon in the neighboring images from a safely released grass cocoonworm. The photo was taken on the loggia, the model was alive and moved quite freely.
On http://www.diptera.info/forum I got this one too post
Maybe I have the same beast?

Dipterologists have deceived you

The link shows a photo of Trogus lapidator - a common parasite of the swallowtail (a completely different sculpture of tergites of the abdomen with a blue tint, and most importantly - a prominent cone-shaped shield). By the way, it is quite likely that its larva was used as a host by Trigonalis hahnii, which was hatched from the pupa of the swallowtail
