When I was younger I was fascinated with butterfly collections -- I don't know if I'm *all* in for entomology, but I understand the interest.
That's very cool! Entomology is the science and study of insects. Did you have a personal collection?
No -- I think I disconnected from the fact the butterflies may have been *killed*, you know what I mean?! THAT part felt a little selfish, just for the sake of collection.
I'm sure it required a disconnect as butterflies are beautiful with large and brightly colored wings.
Yes, the variety is stunning. We lived in Hong Kong once upon a time, and I remember seeing *huge* brightly colored butterflies and smaller ones that I loved for their cobalt blue wings.
Cobalt is such a beautiful color with blue pigments and have been around since ancient times for paints and jewelry. 
Definitely one of my favorite colors. How about you?
I love all the colors of blue which most have a mixture of of other color. Azure has a little green and ultramarine has a slight tone of violet.
The description is beautiful. It *sounds* like a butterfly wings -- or other insect wings!
I'm surprised to see that butterflies have a four stage life cycle! Do you still collect or do you just admire from a distance now?
