Found this beauty while washing the deck furniture this spring. I was so excited I had to get my Husband to take the pictures. I couldn’t hold the camera still.

Male Io Moth

Male Io Moth

Dear Teri,
This beautiful Giant Silk Moth is a male Io Moth.  Males of the species can be distinguished from female Io Moths which have brown rather than yellow wings.  They eyespots on the underwings of both sexes are believe to deter predators into thinking the moth is a much larger creature that might decide to eat the predator.

Hello!
We found this relatively small, maybe an inch long, beauty on the outside of our garage door this morning. Last week we spotted an Imperial Moth in all his glory, wings splayed, on the side of our house but he was much bigger than this little guy. Even though he is much smaller I’m wondering if this is an Imperial as well. Thanks and my five year old and I LOVE this website. Having just moved to the south we are using it to identify all sorts of new bugs (our latest is a Giant Stag Beetle) that cross our paths.

Dear Sheri,
Thanks so much for the compliment.  The Imperial Moth and this lovely Rosy Maple Moth are in the same family Saturniidae, but they are distinct species.

I saw this yellow and lavender moth on an ATM July 18 2014. Only in inch or two long . Too small to be an imperial moth I think? Thanks

Let me tell you about this moth, it was pretty big. A little smaller than a luna moth, I found it while coming home from work. It was smashing itself into the ground over and over and over, and was so loud I thought it was a dog with long claws trotting up the street to me. I made an attempt to catch it, but the damn thing would not stop it’s furious flapping frenzy. Woke up this morning to find it dead on my porch with it’s abdomin busted out like it was possessed by something unholy! I’m mostly just curious, what kind of moth and what do you think did it in? Personally I’m thinking parasite possession!

Bedraggled Imperial Moth

Bedraggled Imperial Moth

Dear Skye,
Based on its condition, this Bedraggled Imperial Moth was at the end of its short life, and it appears it encountered considerable trauma, perhaps getting caught in a storm or falling victim to some predator like a domestic cat or dog or possibly a bird.  One cannot appreciate the beauty of this lovely moth in its present condition, and we have numerous images of more pristine Imperial Moths on our site.  Like other members of the family Saturniidae, Imperial Moths do not feed as adults and generally live for less than a week, long enough to mate and lay eggs.

Hi, can you help identify this moth. A small swarm came to my deck this afternoon, only one is still here. North Georgia, wooded area. There is also a large white spot on the lower wing (white spot, on the purple wing if opened).

Oakworm Moth

Oakworm Moth

Hi Christine,
This is an Oakworm Moth in the genus
Anisota, and it our opinion, it looks like the Pink Striped Oakworm Moth, Anisota virginiensis, that is pictured on BugGuide.  Oakworm Moths and the Polyphemus Moth are in the same family, Saturniidae.

I live in central PA and found this moth that looks like an owl…I would love to know the name of it!

Io Moth

Io Moth

Hi Ricki,
Owls are top of the foodchain predators, and if you think about it, the ability to mimic an owl would be a very effective defense mechanism, especially creatures who are preyed upon by creatures that might be prey to owls.  There are several moths that very effectively mimic the face of an owl through the evolution of false eyespots known as ocelli.  The male Io Moth in your image is one such North American moth.  Female Io Moths are very effective owl mimics as well, but female Io Moths are brown instead of yellow and they are even larger than the males, a textbook example of sexual dimorphism.  Another good North American Owl Mimic is the Polyphemus Moth.  Both Io Moths and Polyphemus Moths hide their ocelli while at rest, but if they are disturbed, they quickly “open” their eyes, potentially frightening off any threatening creature.
