Observations without photo

I do it with spiders in New Zealand, I have a custom Identify filter that views ALL observations of aranae, regardless of photo-less or captive or RG status etc. The photoless observations are often just ones from observers using the app and the photos might take a couple days to get uploaded… but sometimes I see photoless obs of spiders that I know are not known to be present in NZ, and those I watch closely to see if an image gets uploaded… after a week or so, if still no photo I either ask the observer if they are uploading a photo, or I make an explicit disagreement at aranae with a comment regarding the absence of the species in NZ, and inviting them to provide further support for the species level ID. Sometimes it just turns out to be a pin location that got accidentally moved from Australia to New Zealand! I would speculate that visitors to NZ who start using iNat for the first time on a trip here might be adding photo-less observations of what they know they have seen before in their home country, and consequently the pin location defaults to where they are at the time… there could be many reasons :)
