Wellllllll . . . it is a Zebra Longwing or Zebra Heliconian BUTTERFLY! 🙂 (Linked to my gallery.) And this one is the first I’ve seen in my garden and only my third in Costa Rica, with the other two at Xandari Resort Alajuela and El Castillo-Arenal in the Butterfly Conservatory. The scientific name is Heliconius charithonia and it is found throughout South & Central Americas up into the southern half of the U.S. At the time of this writing in June, 490 had been observed & photographed in CR on iNaturalistCR.
¡Pura Vida!
