No, please do not use iNaturalist to record Glow-worms. Its a crap system designed oversees where they have nothing else suitable. In the UK we have iRecord (the UK Biological Records Centre recording system) which is a far superior system. iNat provides totally useless/vague data on the whole and as such most of the iNat records dont get verified when migrated to iRecord and so dont end up on the NBN Atlas. The three of us who are the national record verifiers for Glow-worms really dont like iNat and I hear similar comments from county recorders of various taxa,
With respect, your opinion of iNatualist (developed overseas, as you note, at University of California, Berkeley, but used worldwide not just in this septic isle) doesn't seem to entirely agree with the managers of iRecord itself which actually imports
verified records from iNaturalistUK as described in

iReport would seem to be a more professional tool than iNaturalist and be correspondingly less informative, and rather more daunting, to the more casual, yet interested, user which most of the participants in this topic would seem to be.
Just don't use both for the same records then...
