Can observations be deleted from the dashboard?

No, observations on the dashboard can’t be edited like that. I’m not sure what your use case is, but you might be interested in using the Identify page instead, if you aren’t already, e.g. obs with at least one Scarabaeoidea ID that are currently at rank subclass or higher: https://www.inaturalist.org/observations/identify?ident_taxon_id=48202&lrank=subclass
