In general, wholesale addition of specimens from biological collections to iNat is discouraged (one thread about this here: https://forum.inaturalist.org/t/museum-herbarium-collection-digitisation-on-inaturalist-yes-or-no/5374 but there are others). The main reasoning behind this is that iNat is primarily for recording interactions between people and nature, and digitizing an older collection isn’t really this.
That said if there are a few specimens that you are looking for ID help with, etc., this shouldn’t be an issue. There are also other places online that you may be able to try (BugGuide, there’s a lot of bug folks on Reddit as well). They might be able to notice some commonality between the various specimens and point you in the direction of a collecting locality.
