I’ve used one of those buttons just once. IIRR someone had identified a spider as Argiope keyserlingi (St. Andrew’s cross spider), but the stabilimentum looks like a roughly circular area about as big as the spider, whereas the St. Andrew’s cross spider is named for the stabilimentum that looks like a big X extending well beyond the legs, which are held like the crossing part of the X. I don’t remember the wording on the buttons, but it was confusing. I managed to disagree with the A. keyserlingi ID, which is what I wanted to do.
