This beauty was in the house hanging from my hat a few Julys ago. You’d think identifying a bright yellow moth with a cute pointy nose would be a cinch, but that hasn’t been the case. Any ideas?

Canary Shouldered Thorn Moth

Hi Storm,
We did a quick fruitless search, but our problem is we don’t know where to begin, and our two first choices are both big categories.  The wing shape and position makes us think this is a member of the family Geometridae, but the stout body and other features seem more like Noctuidae.  We will contact Julian Donahue to see if he has any ideas.

Julian contacts some experts
Jon and Gary,
Which of you can be the first to come up with a name for this beast from B.C.?
ID is being requested from the What’s That Bug? website, so any additional comments you can provide on hostplants, distribution, seasonal occurrence, etc. will be informative, and most likely will be posted with attribution.
Many thanks. (And if you’re at the Denver meeting I’ll understand a delay in responding),

Gary Anweiler Responds
Hi Julian et al
I believe this is a specimen of Ennomos magnaria, a large heavy bodied variable Geometrid

Many thanks, Gary.
Looks pretty good to me, and compares favorably with pics on MPG:
Daniel: Common name is Maple Spanworm Moth. Map and other images at link above.
Guess you win the lollypop, Gary.

Thanks Gary and Julian.

Thank you (and your network!) for identifying my house guest. Following the Moth Photographers link, I found this on the next page. What do you think?
cheers, Storm

Hi again Storm,
The common name Canary Shouldered Thorn Moth seems more fitting based on your photos.  Both moths are in the same genus and they look similar.  Often exact species identification is impossible based on photos, especially when variation is possible and species look similar.  We will send your latest query back to Julian and Gary.

Gary Anweiler confirms
Absolutely !!!  I was unaware of a second species of Ennomos out there.  So I learned something too.  I will take 2% of the credit, as getting to Ennomos led to finding the correct one; but I will be returning the lollipop!

Julian and Gary
I was in the field when these emails came. I agree with Gary with the following problem.
I do not have any vouchers of this species.  Photos on the CNC website and in the Geo’s of Scandinavia do not show as many darker lines on the upper forewing.  Those photo’s show only two lines.  Inoue’s Moths of Japan show no other matches.
Hi again
The comments I just sent to Gary and Julian applied to E. alniaria, not E. magnaria.

Thanks Jon,
I am Daniel Marlos from What’s That Bug? a pop culture insect identification website.  I have no scientific background, so please excuse me if I ask for a bit of clarification.  According to my understanding of your comment, it seems you are favoring Ennomos magnaria as the proper identification.  Can you please confirm.
Thanks again for your expert input.

I think it is E. ainiaria.  My earlier comments, which you did not receive, referred to the upper forewing pattern.  The photo you sent seems to have a more patterned surface than any other photo I found of E. alniaria.
Could you send me the locality information and date that the photograph was take and the name of the person who took the photograph.
So far this species is only known from the SW coast of BC and one interior location [Moth photographers group-unverified].
Jon Shepard
This is an introduced species

Storm provides some historical data
July 28, 2012
hi Daniel,
I’d be happy to provide what ever information I can for Jon. He’s right about it being unusual: The Moth Photographers Group page on this moth says it was introduced in/around 2006 to two areas of BC. The photos on their page were taken in Burnaby, BC, which is right next door to me.
BTW, the embedded date (2005) on my photos is wrong – that particular camera would reset the date whenever the batteries died. The actual date (2007) is given as the name of the photo.
Thank you again for your help. I’ve tried to figure this out for a long time and got nowhere until you started asking questions!
cheers, Storm

Subject: Pompilidae or Mimic?
Location: Grand Cayman, Cayman Islands, British West Indies

This insect emerged from a chrysalis in an office on Grand Cayman (British West Indies) yesterday. Since I don’t think it fits the wasp life cycle, I suppose it probably isn’t a spider-hunting wasp, but more likely a moth that looks similar to one. Can you identify it? Thanks very much. I love What’s That Bug!

Spotted Oleander Caterpillar Moth

Hi Melissa,
This Spotted Oleander Caterpillar Moth,
Empyreuma affinis, or a closely related species or subspecies, is a very effective wasp mimic.

Thank you, Daniel.  We over here at the vet school on Grand Cayman appreciate the info.  And I realized in retrospect I probably should have indicated “pupa” rather than “chrysalis”.

Trying to find the name of the butterfly I saw today in Solomon Islands.
Thank you!

Possibly Lyssa mutata

Dear Kengo,
This is not a butterfly.  It is a moth in the family Uraniidae, and we recall a similar looking species from our archive.  We found this image of a Tropical Swallowtail Moth from Malaysia,
 Lyssa zampa, posted in January, and it appears to be closely related to your individual.  Knowing that islands often contain distinct species and subspecies that have developed in isolation, we tried to find any references to moths from the genus Lyssa on the internet.  The only match was what appears to be your moth on FlickR, but alas, it is not identified though the location is listed as Vara Creek, Honiara, Guadalcanal, Solomon Islands.  The subfamily Uraniinae on Wikipedia mentions a species from the Solomon Islands, Lyssa mutata, but there are no photos and we could not locate any photos of Lyssa mutata on other websites online.  We can only speculate that your moth might be Lyssa mutata, but in the event we are wrong, we are still confident that we have correctly identified the genus.

Subject: Clymene Moth
Location: Bradford, NH

My husband came across this moth when he was working on our barn. He found it around 8:15 in the morning. Some consider this moth to be spiritual, a cross on it’s back or an image of Jesus on the cross, you decide. One site I stumbled across said, ”If you find this moth your prayers have been answered and where you found it will be protected by angels”. I’m not a religious person but this moth was found one week to the day and time my father passed away.
I love this website. You have so many species of bugs and the site is very informative! Thank you!

Clymene Moth

Dear Lee,
There is a long history of various cultures associating moths, but more commonly butterflies, with the notion of rebirth or resurrection because of the metamorphosis process from a dormant pupa to a winged and beautiful imago or adult.  We have no problem with spirituality being associated with insects and we find the complexity of life on our planet to be absolutely divine.  We just finished posting another image of a Clymene Moth that was submitted today as well, but in that image the cruciform pattern was not as apparent as the moth was revealing its peach and black underwings.

Subject: Unique moth for my yard

Hi Bugman,
I thoroughly enjoy the bugs that I see around my yard throughout the spring, summer, and fall months. Moths are one of my favorites, along with dobsonflies, katydids, and the various spiders that populate the area. However, this is a moth that I have not seen before so I would appreciate if you could identify it for me. I see that a person from the neighboring town of Athol recently found a unique moth in her area (I have not seen the tiger moth around my property either!) so here is another beauty that I believe to be unique to our area. Thanks for your services, and it goes without saying that your website is FANTASTIC.

Clymene Moth

Dear Mike,
Thank you for your kind compliment.  This little beauty, the Clymene Moth, is another species of Tiger Moth.  Your photo which shows the underwings as well as the upper wings, is a very nice addition to our archives.
We need to go back through our recent mail because we received an unopened email with Clymene Moth as the subject line and we should consider posting that letter as well.  If we had posted it, you might have been able to self identify your individual.

Subject: Imperial Moth

Hey bugman,
I thought I would share with you a photo of this Imperial moth that my family and I and some friends of ours came across on the way back from our vacation in Charleston, SC. It was at a rest stop about halfway between Columbia, SC and Asheville, NC. It is one the the most beautiful moths I have ever seen. I hope you enjoy the pic! Sorry its not better quality. It was taken with my Android phone. Feel free to rotate or crop to make it fit better on your site. Thanks for all you do! Your website is amazing!

Male Imperial Moth

Dear Michael,
Thanks for sending us your photo of a female Imperial Moth and thanks for the compliment.

Thanks so much for posting my photo. I thought this was a male though, honestly. I thought females were more yellow. I’ve always read that males have more purple.

Thanks for catching our error.
