Taxonomic question

In this post:

There’s an excellent photo, and an apparently correct identification (Mr Brooks is seldom wrong). But iSpot has put Nowickia into the Sciaridae: I’d thought it was in the Tachinidae. Is this a recent change?

Looks like a taxonomic error. Sciaridae and Tachinidae belong to different suborders.

yes, this is an iSpot issue and is similar to many. The iSpot dictionaries have not been updated for a few years, probably 5.
Wiki(tree) is usually reliable
The CoL is always up to date (six monthly)
All the Other Obs have the same issue
Our ‘friends’ in iNat have it right
Oh well.
