I’ve seen this moth three different times, but finally got a good enough picture to send you. I’d like to know what it is and what the purpose is for the stick out thingy!

This is one of the Grapevine Looper Moths in the genus

Hi, I found several black-and-white butterflies flying around some damp soil at the 4200-ft. elevation of Mt. Rainier in Washington state on June 26. I photographed one of them; not a great shot, but I hope it shows the essentials. Can you tell me what it is? Thanks.

Diurnal Geometrid Moth

Diurnal Geometrid Moth

Dear gardenjim,
This is not a butterfly, but a diurnal Geometrid Moth in the genus
RheumapteraBased on this BugGuide image, we believe it may be Rheumaptera subhastata, but it may be a different species, because according to BugGuide:  “The variation in pattern among individuals of R. hastata and R. subhastata is much greater than the variation between the two species. … Since these two species have virtually identical geographic ranges, examination of genitalia is the only reliable way to separate the two.”

Hi!
I found this bug in my backyard and I was wondering what species it is? It is fairly common flying around and feeding on the lilac bush. I have searched several bug databases and I am unable to find the name of it. Any help would be greatly appreciated!
Thank you

This moth is on my kitchen door. White for camouflage I’m assuming. It’s about 1 -1/2 inches from wing tip to wing tip. Soft fur on head. It looks like a stealth bomber. Very beautiful. May have black legs, small horizontal antennae.

Dear Trish,
Your moth is is the family Geometridae, but we are uncertain of the species.
  It may be an Omnivorous Looper, Sabulodes aegrotata, which is pictured on the Moths of Orange County site.

Hello! Hope your spring has brought all sorts of buggy critters your way. My son found the strangest bug crawling across the leaf mould beneath some willows. My first thought was, could this be a half-pupated butterfly? She had a body like a short fat fuzzy grub (I could see pale green flesh in between the abdomen ridges when she flexed), butterfly-looking legs that pranced, and what appeared to be little fuzzy wing nubs. She had a very tiny head with no proboscis or discernible features, only spindly antennae.
What is she?
Thanks for your help!

Flightless Female Moth

Flightless Female Moth

Dear Rebecca,
What we know for certain is that this is a flightless female moth, and we have done considerable research, and though we do not have a definitive response, we believe we are close.  The Moth PHotographers Group has a page devoted to flightless female moths.  Our first research took us to the possibility that this might be one of the females in the genus
Orgyia, the Vapourers or Tussock Moths, and the Douglas Fir Tussock Moth, Orgyia pseudotsugata, is found in Western Canada, so we thought that might be a good candidate, but based on the images posted to BugGuide, the legs and antennae are much shorter than your individual.  Though images of flightless female moths can be difficult to find online, a look at the mounted pair of Douglas Fir Tussock Moths on Forestry Images confirmed our belief that it was not your species or genus.  We next turned our attention to the genus Lycia in the Spanworm family Geometridae, and the Stout Spanworm seemed like a good candidate as it is found in Western Canada, according to BugGuide, but alas, BugGuide only has images of males with wings pictured.  The Belted Beauty, Lycia zonaria, which is pictured on the Highland Butterflies UK site looks like a good match physically, but it is an old world species and the markings are different.  Except for the markings which are different, the Belted Beauty pictured on UK Moths also looks quite similar to your individual.  We are concluding that since the genus Lycia is represented in Canada by two species according to BugGuide, and both the Stout Spanworm and the Twilight Moth, Lycia rachelae, are reported from western Canada, that one of those species is most likely your flightless female moth, but alas, we had no luck finding any online images of females to compare.  Perhaps one of our readers will have more luck than we have had.

Dear Bugman –
I would love help in identifying this green moth from Tanzania.
Perusing pictures, the closest thing I would find was the Large Emerald and other geometers.

Geometer Moth

Dear Robert,
We agree that this looks like an Emerald in the family Geometridae, and we attempted a more specific identification, but alas, the best we could do was this image on iSpot that is only identified to the family level Geometridae.
