Can’t answer your question, but I’ve been checking observations of japanese beetles (Popillia japonica), one of the most common insect species in the eastern USA with thousands of observations, to find evidence of a parasitic fly, Istocheta aldrichi. This non-native species was introduced as a biological control and seems to be extending its range (in some cases via human intervention) from areas of original introduction in northeastern USA. These are usually observed as eggs deposited on the pronotum of the beetle (e.g., https://www.inaturalist.org/observations/129331036), and the person uploading the beetle observation is usually completely unaware of their dual observation. These observations have been very useful in documenting the spread of this species, and its increasing abundance in areas where already present.
BTW there are virtually no observations of the adult fly at all; it’s a very nondescript tachinid species and only a specialist would be able to identify them. So the easily observed and recognizable eggs are about the only way to document this species.
When I am travelling and have some time to iNat, I really like it when I do a preview look at observations in the area, and the list not only reflects species that I am likely to find there, but also their relative abundance (or at least my chance of encountering it). I also like having enough regular records that I can get an idea on seasonality as well. That means I personally would encourage you to make regular observations of common things.
I try to post to reflect abundance, so I do post dandelions and daisies as well as the curious plants I can’t identify yet (I have much to learn!). But as someone who has spent their life with data, don’t censor, don’t try to figure out what future researchers will want. Post everything you find.
I was struggling to correct it as you were typing too! I know ! Phrenology is the study of the shape, contour of the skull. You know the bumps on my head!!!
If I was hired on as the future researcher’s field assistant, sure. But as I am doing this for free in my free time, I’ll stick to posting what I feel like posting.
