Yes.
- iNat users are welcome to record any observation they have with the living world. We don’t need to police the merits of particular users’ choice of what to observe. To me, it seems these organisms would probably be marked as captive/cultivated because they were in the store or home due to human actions. If the observer believes the organisms got there of their own accord, then maybe they would be wild. Either type of observation is fine.
- Tracking occurrences of non-native species moved around by the agricultural industry is certainly one of the many ways iNat data can be used, and that might include spiders and plant seeds hitchhiking on produce. But in any case iNat doesn’t require observers to demonstrate that an observation has provable value.
