Some weeks you don't get to name any new species, some weeks you get two. Here's my latest, complete with #OpenAccess link to the paper:

Another One!

When it rains, it pours! Two days after I posted here about the newly named species Earomyia veratri, another paper of mine has just been published, describing another new fly species. This one is …

In my pursuit of an unknown species of leaf-mining fly on false hellebore, I accidentally discovered a new species of stem-boring fly, which had a zillion other insects living in the stems along with it.

False Hellebore Fauna

For the past decade, I have been trying to rear an unknown species of Liriomyza (Agromyzidae) that mines leaves of false hellebore (Melanthiaceae: Veratrum viride). The mines are very scarce consid…

It's not at all clear to me from that document why this species would be considered a pest. There is no mention of VSC, which I haven't heard of before.

Since you're looking at a lot of redbud seedpods, I'm curious what you think of this discussion/interpretation of the mines that sometimes occur in them: www.inaturalist.org/observations...

But the few bark mines I have seen on any kind of chestnut have been Marmara sp.

The type series of Ectoedemia castaneae, now considered a synonym, supposedly was reared from galls on chestnut, but no one has seen them--or reared it from chestnut--since 1913 or whenever that was. The thinking is that the larvae actually made bark mines on the twig that had the galls.

I do it from time to time. Not sure how often it sticks.

That is a terribly unfortunate common name for a moth that feeds on both oak and chestnut, and is one of numerous moths that do so. One of the chestnut specialists would be more deserving of it, but I don't think any ambiguous common names are useful.
