Hi. I saw this moth on the side of a shed in my backyard. It is large – 3-4 inches across. Can you identify it for me? Thanks for your help.

Dear Todd,
After a bit of searching, we identified your Geometrid moth as a Common Lytrosis,
Lytrosis unitaria, thanks to this BugGuide image.  According to BugGuide:  “Forewing length 21 to 30 mm., females larger than males.”  Though BugGuide does not list any Manitoba sightings, The Moth Photographers group does list a sighting that appears to be Winnipeg.

Hi,
I’ve recently tried to identify some of the insects I photographed in Costa Rica, in the summers of 2009 and 2011. I have had some success (this site has been of great help), but this fellow has been eluding me so far, so I figured I’d ask the experts.
This was taken in Monteverde, Costa Rica, on June 27, 2011.
Thanks in advance

Geometer Moth: Pityeja histrionaria

Geometer Moth: Pityeja histrionaria

Dear Thibaud,
Considering the beauty of this striking moth, this was one of the more difficult searches we have undergone in recent memory, but before we provide you with the information we have gleaned from the internet, we first need to rant on Pinterest.  In our minds, the Pinterest site is the scavenger of the internet.  Pinterest pilfers images from other sites, and because it has so many users, search engines bring up images on Pinterest even before they bring up those same images on the originating sites.  Then one must register to even access the original site.  We are deeply offended by Pinterest.  Our word searching led us nowhere, so we decided to do an image search, which we rarely do, and the only two internet images we could locate of your moth were on Pinterest, but we could not trace the originating sites since we flat out refuse to register on Pinterest.  Now that we have that off our collective chest, we can tell you what we learned.
Our first lead was a FlickR posting by Andreas Kay of an image taken in Ecuador, and we learned the identity of
Pityeja histrionaria in the family Geometridae.  On FocusOnNature we learned:  “Pityeja histrionaria ranges extensively in much of South America. It occurs from Mexico to southern Brazil.”  Though we did not learn much more about the moth, we located another image from Ecuador on FlickR, an image from Peru on Project Noah and an image on the National Moth Week site with no location.  Several sites have images of mounted specimens, including Lepidoptera Barcode of Life and Encyclopedia of Life.  This looks to us like it would be a diurnal or day flying species.  Are you able to provide any insight?  Did you find this lovely Geometer Moth in the morning after it had been attracted to a light lit at night?

That’s the one! Thanks for the amazingly fast reply!
I apologize, I should have specified, I did see this one at night, attracted to the lights of the field station.
As for Pinterest, I fully share your sentiment, and all I can say is that I neither have an account nor use it myself.
Cheers
Thibaud

Given my horrible guess on the last moth, I hesitate to say I know what these are, but I spent a lot of time at the Discover Life website comparing photos, so I can say with reasonable certainty that I have a photo of a horned spanworm moth. I’m not quite as certain about the large maple spanworm moth, but I found images that were very similar so I’m going to give it an 85% certainty. Fingers crossed. I do love their amazing leaf mimicry.
thanks

Dear Grace,
Leaf-mimicking, brownish Spanworm Moths in the family Geometridae can be extremely difficult to identify to the species level, and we often avoid such specifics, preferring a general family identification.  We agree that one of your moths is possibly the Horned Spanworm Moth,
Nematocampa resistaria, based on images posted to BugGuide.  We are not convinced that your second moth is a Large Maple Spanworm.  We believe it looks more like the Curve-Toothed Geometer, Eutrapela clemataria, a species also pictured on BugGuide.  In both cases, we wish someone with more experience determining the species of Spanworm moths would weigh in on an identification.

I am having issues id’ing this moth. We found them in upper Michigan in the pine barrens where the Kirtland’s warbler nests. I have narrowed it down to a possible black-banded orange (Epelis truncartaria)

Black Banded Orange

Dear Glenn,
In our opinion your identification is absolutely correct, after we compared your image to this image of a Black Banded Orange,
Epelis truncataria, on BugGuide.  According to BugGuide:  “Adults fly during the day and are not known to be active at night.  Generally uncommon and local in the southern parts of its range; common and widespread across the boreal forests of Canada and Alaska.”

Dear Tessa,
Eggs can be very difficult to identify, so having images of the female insect laying the eggs is one way to ensure the identity of the eggs.  This moth is an Omnivorous Looper,
Sabulodes aegrotata, a species found in the western states.  Here is a BugGuide image for verification.  According to BugGuide:  “The larvae feed on a large variety of herbacious and woody broad-leaved angiosperms. Plants in 27 familes have been reported as hosts, and the species’ feeding occasionally causes damage to to orchard trees such as avocado, citrus, and walnuts.”  Many moths that are general feeders do not concern themselves with laying eggs on an actual host plant as the young can forage once they hatch.  Because we will be away from the office for a spell in June, we are postdating your submissions as well as other postings to go live during our absence.

Hi bugman,
This moth appeared in my house on 1st April 2016. It stayed for the day and then disappeared. Could you please tell me what is its name?
Thanks,

Dear Eddie,
Why did you wait nearly an entire month to submit your images?  It took us a bit of time to identify your Orange Trimmed Satin Moth,
Thalaina selenaea, though we did notice several similar members of the genus on Butterfly House.  Not until we found this FlickR posting were we convinced our ID was correct, and we verified its identity on ipernity.

Thank you so much Daniel! I tried searching the internet myself but couldn’t find this Orange Trimmed Satin Moth. It didn’t occur to me that there would be a website dedicated to identifying bugs until a few days ago.
I had never seen a moth like this before and it also just happened to appear on my 10th Wedding Anniversary so it made it extra special because the colours reminded me of my wife’s wedding dress.
Thanks again and I appreciate the rapid response!
Cheers,
Ed.

Hi again Ed.  Thanks for letting us know about the memories this Orange Trimmed Satin Moth triggered for you.
