Lebeau's Silkmoth

Candidates for this one are some Rothschildia sp.: Orizaba and Triloba which were almost identical and Lebeau. In your case it must be Triloba considering the altitude (lowland), but the patches and markings are not matching for Triloba, so in my eyes it should be Rothschildia lebeau.

Thank you so much bayucca for this info :) I will try to be more accurate with my descriptions, I have always loved nature and finding project Noah was awesome for me, is the perfect way to share and learn about this wonderful world, I found this moth today in the morning in my workplace, i work in a windfarm (green energy) and we are very close to some forrest protected areas so we see a lot of insects and animals every day, we are at an average of 800 meters above sea level, haha thanks and PURA VIDA bayucca :)

Important in insects are: Several shots from each side, always focus on the eyes (that's not always easy!), at least one full shot of the whole insect (this one is a little bit too small), information about the location/habitat, altitude (in this moth altitude is very important), size!, colors of body, head, legs (in some bugs there are 2 colors, in this case it is important to look at the colors of the "knees"). Only 1 insect or some together?, different stages (babies and adults)?, male and/or female (if you know that ;-)...). So, shortly told: Get as much information as possible and learn to describe and to look very carefully at each detail. Needs some practice but you will learn a lot about the insect world and it is definitely VERY exciting, specially in Costa Rica!!
¡Pura Vida!
So, at which altitude was this picture taken??

Cool..
