Simplex Clearwing Butterfly

Pteronymia simplex simplex


My first spotting from Costa Rica :) Small butterfly around 5 cm in size with clear wings with orange coloured borders/trimmings on their wings.


Adults range from Mexico through Panama and Colombia. Saw lots of them in one particular part of the mountain, only deep into the forest trails along a river.


Most of the time, they are very skittish like all butterfly but much easier to get close to them to take pictures when they are feeding. They seems to be mostly feeding on bird's droppings :D New Organism to Project Noah

Congratulations Albert! Your spotting has been chosen for Project Noah Fact of the Day: "The Nymphalidae are the largest family of butterflies with about 6,000 species distributed throughout most of the world. These are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colorful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies. ~Wikipedia

Thanks, @jeslowery, @Leuba and @Mark :)
It was interesting to me as I hiked 3 different mountains in the same vicinity and only found them in one.

Great spotting! It would be GREAT if you could add your insect spottings from Costa Rica to the mission "Insects of Costa Rica" ;-).

Thanks, @Antonio.
I had thought this is a Glasswing butterfly (Greta oto) but bayucca gave the corrected ID. So, this could be the first Spotting of Pteronymia simplex simplex on PN?

Wow,great find Albert,just beautiful,congrats and thanks for sharing

Nymphalidae, Danainae, Ithomiini, Pteronymia simplex simplex.
It cannot be a Greta, veins and markings are different.
