Carol, we kick-off the first ever Moth Week with this beauty which is actually part of the National Moth Week organization's logo :) Congratulations on another awesome Spotting of the Day! We thought is was fitting to have one of your moths start things off for us and we're looking forward to seeing what other gems you photograph this week. It's Moth Madness!

"The big eyespots on each hindwing of the colorful Io moth are a defense mechanism meant to frighten off potential predators. "

Love it! Absolutely beautiful! Amazingly clear shots too Carol, definitely a favorite. Seems I spotted the caterpillar to this in Brazil. Congrats on 650 too, keep em coming!

I don't do anything special to attract the moths. I believe it is because I live near woodlands, meadows, farmland, mountains, large lakes and rivers. I am enjoying searching for moths at night.
