Taxacom: Entomological collecting at altitudes higher than 4, 500 m (more than 14, 500 feet)?

Some Tibetan Parnassius species only fly at 5,000m or more, e.g.
Parnassius schultei, P. huberi and P. hide (which can be found at the
slightly lower altitude of 4,700m too).

Have any entomological collections ever made at altitudes higher than 4,500 m (~14,500 feet)? I am not asking for observations of something seen flying (which I know there are quite a few observations of bumble bees and I believe even one Lepidoptera that were seen flying at really high altitudes in the Himalaya) but rather more "solid" collecting such as traps, or netting...

Especially the subfamily Microgastrinae which are caterpillar (Lepidoptera) parasitoids. As far as I know there is a potential to have some species occurring at altitudes a bit over 4,500 m. But I have not found any solid evidence yet. Based on specimens housed here in the Canadian National Collection, I described in 2018 a species of Microplitis from four specimens collected in Colorado (Mount Evans) at altitudes between 3,658 m (holotype) and 4,267 m (paratypes) (link to paper here in case someone is interested in seeing the species, which I named as "altissimus" to refer to the altitude it was collected: https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fzookeys.pensoft.net%2Farticles.php%3Fid%3D22869&data=05%7C01%7Ctaxacom%40lists.ku.edu%7C33bb15e41dc042f5f2fd08da24a67414%7C3c176536afe643f5b96636feabbe3c1a%7C0%7C0%7C637862595466453701%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=YLLqDkqZzW%2FeICxulmP%2FlI74HkhHjPZ8m0zOJxObyDs%3D&reserved=0) . There is a road that reaches the summit of that mountain and thus it is relatively easy for collectors to access that mountain and collect at such altitude (the mountain peak reaches 4,350 m or some 14,200 feet, but I have not seen any specimen from higher than 4,267 m). Similarly, I am describing now a new species in the genus Dolichogenidea collected in Ecuador and Peru at 4,000-4,100 m, but here it falls a bit short of my previous species "record". And I cannot find any historical reference higher either. Thus, at least until this point I have failed to find any evidence of collecting for parasitoid wasps at altitudes higher than 4,200 m or so.

But I am pretty sure that there are many places in the Andes, close to the Equator, where some vegetation can be found way over 4,300 m (in fact, more like close to 5,000m), and thus any entomological expedition done there should have collected parasitoid wasps. Same could apply to Africa (I would assume that Kilimanjaro would be a good guess? But there are also a few other possibilities), and perhaps to Himalaya. The record for the highest tree line is discussed in many places (I believe that South America wins that one) but actually even if only grasses that would be sufficient for potentially having caterpillars and therefore, parasitoid wasps attacking them. After all, in the northermost locality in the world (Alert, Ellesmere Island, Canada, 82°30′N) with a brutal artic environment, there are many species of parasitoid wasps. So, I gather that finding them at altitudes of around 4,500 would be reasonable.
