Unknown moth?
Location: Chiang Mai, Thailand
January 31, 2011 9:29 am
The two different species or male and female of the same species were taken in late January in our dry season at 800 meters. They were photographed at the same small pool on consecutive days at around 1 pm. The pool was formed by a depression in granite rock about 10 feet from a larger pool fed by a small waterfall. The area around is wooded but this spot is in a 75 foot clearing due to rock. I’ve looked everywhere on the web and nothing is even close. I’m guessing Arctiinae. Any suggestions?

Clearwing Moth from Thailand

Dear Dave,
Though there is a group of Arctiids that mimic wasps, there is another family, Sesiidae, that are also wasp mimics, though the family is collectively known as Clearwings.  There are many species in this family that exhibit marked sexual dimorphism, so much so that males and females look like different species.  Many Sesiids have larvae that are borers in the stems and roots of woody plants.  You can see many examples of North American Sesiids on BugGuide.

Clearwing Moth from Thailand

We are going to do a quick search of the internet to see if we have any luck with this species, but we have a time constraint this morning as we will be closing the offices and not responding to any additional letters while we are at our day job.

What’s this bug?
Location: Hobart, Tasmania, Australia
January 30, 2011 5:44 am
Hi, thanks for the website. I snapped this very large moth in my back yard in suburban Hobart, Tasmania, the coldest (and island) state of Australia. We are in the middle of summer and it was a warmish night of about 15 degrees celcius. I have not been able to find any information online about this moth except that it resembles many of the hepialidae family. I have seen one of a similar size in the bush but this sighting was a first around the city. Hobart is surrounded by mountains & bush so the wilderness is never very far away from suburbia.

Wood Moth we believe

Dear Bug info,
Our first impression, because of the long narrow wings, was that this was a Hawkmoth in the family Sphingidae, but after a brief moment, we revised our opinion in alignment with your speculation.  We agree that this interesting specimen resembles the Ghost Moths or Swift Moths in the family Hepialidae, but like you, we have not been able to find any matching images on Csiro which includes this wonderful Hepialidae slide show.  We could not find a match on the Moths of Australia Hepialidae page either.  We then researched our original impression, but there are no matching images on the Moths of Australia Sphingidae page either.

The large body of this specimen inclines us to believe it is a female full of eggs.  When Daniel was researching his book, The Curious World of Bugs, a Ghost Moth from Australia was discovered to hold the record for the most eggs laid by an insect that was not social since Ants, Bees and Termites can lay millions of eggs over the course of the queen’s life.  Here is that bit of information courtesy of the Book of Insect Records published online by the University of Florida:  “An Australian ghost moth, Trictena atripalpis (see Moths of Australia), is the insect with the highest recorded fecundity among nonsocial species. One female was reported to lay 29,100 eggs, and when dissected, 15,000 fully developed eggs were found in the ovaries.”  We remain puzzled by this identification and we hope a reader will come to our assistance.

Update with Identification
We just received three comments from a reader who supplied this link: of a Wood Moth that looks identical to this amazing creature.  When we finish preparing Beoff Bourgenon (or however you spell Beef Burgandy in French), we will update this posting better.

Green Moths
Location: Lyle (High Prairie), WA, elev. 1450 feet

This green moth appeared in my kitchen last night (the door was open for the dog). These pictures show several views of it. This morning another appeared. Friends think that it is a Pacific Green Sphinx Moth. Is it?
I do have a couple more photos if needed. Thank you,

Pacific Green Sphinx

Dear Martha,
You are quite correct.  This is a Pacific Green Sphinx,
Arctonotus lucidus, also called the Bear Sphinx.  You may read more about its habits on the Sphingidae of the Americas website.  According to BugGuide:  “Larvae feed on plants in the Evening Primrose Family, Onagraceae, such as Camissonia, Clarkia, and Oenothera.”  Though primrose has naturalized in the grounds of our Mt. Washington, Los Angeles offices, we have never been lucky enough to see a Pacific Green Sphinx.

Hello Daniel, I had never seen such a moth before in 72 years and now I’ve seen 3; they were unavoidable fluttering about in my house. I can see the larvae chomping away on the evening primrose roots (local farmers consider the evening primrose a noxious weed). The adults are another story; it’s mid-winter here with lows in the low thirties and upper twenties. Nothing seems to be blooming but maybe the adults do not need to servive very long.
My photos don’t do justice to the richness of color and striking appearance. I hope you get to see a Pacific Green Sphinx during the coming year and can admire it in person, Martha M. Hamil

Thanks for the update Martha.

Cool Moth
Location: Acworth, Ga

While I was working at a gas station one day in the hot Georgia sun, I found this GIANT moth. Well, I’m sure he’s not quite as big as some others out there, but it was the biggest one I have ever seen myself. Actually, we have an overabundancy of huge bugs at my work, every one of the largest bugs I have ever seen have all been seen there. I started posting them to my facebook photos and someone pointed me to here to have them identified. Is it possible that something in on or around the gas station creates super-bugs, or do huge bugs really just exist and we just typically don’t see them?

Rustic Sphinx

Dear Amazed Giant-bug Enquirer,
Your moth is a species of Hawkmoth, the Rustic Sphinx.  Your gas station if attracting insects because of the bright lights.  We don’t know what the surrounding property is like, but often gas stations are near wooded or swampy areas, and that may also explain your insects.  There are many large insects, but they go unnoticed unless they are isolated from their natural surroundings by landing on walls and windows.

Moth from Costa Rica
Location: Valle del Silencio, La Amistad, Costa Rica
January 25, 2011 3:52 pm
Dear Bugman
Last September,one evening,i found during an expedition in the Valle del Silencio, Costa Rica, this rather big moth. Unfortunately, i only managed to take one picture, because it was moving very nervous. Despite my efforts to identify that moth, i haven’t found a picture of one that would really look similar. The Valle del Silencio is on 2500 m above sea level, and there, it is raining up to 359 days a year. I would be very happy if you could help me with this beautiful insect! Thank you very much..

Wasp Moth from Costa Rica

Hi Michael,
Even with this poor camera angle we are able to tell that this is a Wasp Moth in the subtribe Euchromiina.  We will try to identify the species.

Update:  January 21, 2015
We just received a comment that this is
Scelilasia erythrozonata.  We found and image of a mounted specimen on Taxonomy Browser and a matching photo on the German site

Costa Rican Geometrid/Bad-wing? Moth by La Paz Waterfall Garden
Location: Costa Rica
January 23, 2011 12:54 am
Hi. I shot a photo of a moth last May (May 10, 2010) of a moth which reminded me of a geometrid in shape,or very similar to a Dyspteris but with metallic Blue/Green forewing and black hindwing. The trailing edge of all 4 wings is cream colored. The body is ”fuzzy” and orange and the antennae are whiplike, not feathery. It was located on a railing near a light close to where I was eating breakfast on the ”Orchid Terrace” Restaurant. The surrounding environs were open field and secondary cloud forest with an altitude of about 1400-1600 meters above sea level. I was at La Paz Waterfall Gardens. Their Lat and Long are:Latitude N
Longitude W

Unknown Moth from Costa Rica

Dear Joyous,
We haven’t the time to research this at the moment, but perhaps one of our readers will provide an answer and comment while we are at work today.
