If anyone wants to help out with the vast number of misidentified earthworms, here’s the “story so far”: https://forum.inaturalist.org/t/inaturalists-earthworm-problem-and-how-to-fix-it/70743 and something of an ID guide: https://www.inaturalist.org/journal/thirty_legs/110030-photographing-earthworms-for-inaturalist
There are still around 33k Lumbricus terrestris observations to correct (the “most observed” annelid species by an order of magnitude!) but I expect the majority to be wrong. Even just pushing back tropical worms that cannot be temperate L. terrestris or blurry unidentifiable squiggles to order or subclass would make us worm fixers’ jobs easier! While finer IDs are sometimes possible from photos, most earthworms are only identifiable from microscopic inspection or dissection, so it’s quite likely that the bulk of iNat earthworm observations cannot and should not be identified past these broad groups which do not take specialist training to recognize.
