There are 5 different “Cattleheart” (Parides) butterflies that are very similar to this one but I don’t think any are an exact match, so I’m putting it in the Genus and will hope for an expert identifier on iNaturalist to give it a correct species name. Then I will change it in my gallery. These black, red and white Swallowtails (linked to my gallery where there are about a dozen species of these ). They seem to be quite common in Costa Rica and not easy for me to differentiate all of the species. 🙂
¡Pura Vida!
