Just checked Reptile DataBase and nigrocinctus is the only subspecies found in Costa Rica, so if you want to update the name to Micrurus nigrocinctus nigrocinctus, I think that would be correct. Thanks from the snake too for letting it go :-)
Hi Gilma. Just searching my contacts for coral snakes and found this beauty. I just started a new mission: Coral Snakes of the World (https://www.projectnoah.org/missions/240...). If you're interested, I would love to have this posted to that mission. FYI, the "red on yellow kill a fellow, red on black, venom lack" only works north of the Rio Grande. In Mexico, Central and South america, they can be in any order. Half the corals here in our area are "red on black," very venomous. Thanks for posting this long ago :-)
It was amazingly beautiful and the colors so very bright!! It was a juvenile Coralillo, it had the right colors in the right order!! Red, Yellow, Black, ( very poisonous) It had the yellow band across the head, 13 red bands, 6 tail rings and it was 9 to 10 inches long.
This one is likely a male due to size and ability to fly. Large green and brown mantis. Eyes appear black at night. Triangular shaped head with lateral stripes between the eyes. This species has been introduced to North America and is larger than most native species here.
