Can you help I’d this bug? It has been resting for a day over my neighbor’s door. It’s about 4″ wide and brown. We live in Cincinnati. The date is mid August, 2014.

Female Polyphemus Moth

Dear Katie,
This is a female Polyphemus Moth from the family Saturniidae, and like other members of the family, adult Polyphemus Moths do not eat.  They only live long enough to mate and lay eggs, surviving on nutrients stored while a ravenous caterpillar.  Hopefully this female has mated and she will lay fertile eggs.

I found this moth in Coatesville, Indiana. It was the beginning of August, Midday. It had deformed wings, and you can see the size compared to my fingertips. It had a furry body, deformed wings, and it kept laying eggs or pellets on my fingers. the pellets were beige with a black dot in the middle and an almost tar-like substance on the bottom to attach it. I’m really curious what this little guy is called!!!

Dear Deena,
This Polyphemus Moth either has atrophied wings, or they have not completely expanded after emergence from the pupa.

This large (7″ wingspan) moth showed up on our patio and spent a couple days hanging out. I live in an industrial area just outside of downtown Indianapolis. This was the week of August 4, 2014.
He wasn’t afraid of anyone getting close to him, so I was able to get some good photos.
Normally, all you can see are his main wings. Only when he starts to feel threatened does he expose his lower wings (and eyespots).
I’ve looked at hundreds of pictures of moths, but couldn’t find any that matched its unique markings. The closest I could find was a Cecropia.

Polyphemus Moth

Dear Ben Mc,
Like the Cecropia Moth, this Polyphemus Moth is one of the Giant Silkmoths in the family Saturniidae.  Many moths in the family were given names that reference mythology, and Polyphemus was a one-eyed cyclops that figures into the Odyssey, the story of the journey of Ulysses, also known as Odysseus.

Daniel-
WOW! Thanks for getting back so quickly. I never realized how many moths there really were. And they’re not just those grey little things that eat your clothes!
Thanks for being such a great resource-
Ben Mc

I found a bug on the front door of a warehouse. I had planned on visiting your site for identification – the cover image happened to be the same critter.
Are these guys having a good year? I’ve never seen one before.

Hi chrisv,
We cannot say that there are more Imperial Moth sightings than usual this year, though insect sightings do tend to be cyclical, with some years producing more individuals than other years.  This is the peak season for Giant Silk Moth sightings in North America, and each year we get numerous identification requests for members of the family Saturniidae in July and August, though sightings occur from spring through fall.

My dog was “playing” with this moth this morning, so I moved it off the ground to where she couldn’t reach it. We’re in south east Pennsylvania, and its wingspan is roughly 4 inches. It has a “hairy” yellow head, and has a short, stout body about the circumference of one’s thumb. Any idea what it is?

Hi Ron B.,
This is a female Imperial Moth.  Females have more yellow while male Imperial Moths have more darker markings.  The sexual dimorphism is obvious when one is lucky enough to observe a mating pair of Imperial Moths.  Like other members of the Giant Silkmoth Family Saturniidae, Imperial Moths do not feed as adults as they do not have functional mouthparts.  They live long enough to mate and lay eggs.  Hopefully rescuing this gal from your dog will allow her to procreate.  For your kindness to one of the lower beasts, we are tagging this posting with the Bug Humanitarian Award.

Thank you, Daniel, for taking the time to help me know what kind of moth my dog found. She is doing fine resting high up on a fence post, waiting for the sun to go down. Thanks again…
Ron

Hi there! I spotted a moth this morning I’ve never seen before. It’s about 5 inches long from head to tip of the abdomen. It was found on August 3rd, 2014. It was active the night before, probably attracted by the lights on the porch, and was resting this morning. The pictures I’ve taken are it next to a pack of 100s cigarettes (little larger than your average pack) and a standard sized outdoor outlet (which has been taped to prevent roaches from getting in).

Hi Zoe,
We just posted another image of a Royal Walnut Moth, and that one was from North Carolina.  We are surprised that they seem to be appearing much later this year.  We generally get reports in June and July, though BugGuide does indicate that adults fly from May through September.
