White Lined Sphinx Moth

Hey! I just found your site and love it, thought I might contribute a little bit. Here is a little friend, what I think is a white lined sphinx moth. It was a warm Nebraska night when this little fellow landed on me and decided to start posing. It stayed on me for about an hour, even as I was walking around and taking pictures. It was a pretty cool experience. Eventually I had to take it off and it just flew away into the night!

Hi Peter,
We are terribly amused with your photos of a Whitelined Sphinx, Hyles lineata, one of the commonest members of its family and also one of the widest ranging.  The Whitelined Sphinx may be encountered across North America.

New Moth sighting in LA 4-27-11

Hey guys.  I have another moth sighting today.  May be a variation on the one we talked about last week.  Unfortunately this one did not stick around for the mating process.  Here is a picture.
I also found this on my house near my willow.
Thanks
Dan

This Moth appeared on my window screen in Los Angeles yesterday. Is now mating with a second. It is about 3 inches wing tip to wing tip.
What Kind of Moth?
Shoudl I be concerned with moth babies?

One Eyed Sphinx

Dear Dan,
We believe this is a Salicet Sphinx, Smerinthus saliceti, based on the Sphingidae of the Americas website, though we would not rule out the possibility that it is the closely related One Eyed Sphinx, Smerinthus cerisyi.  You have nothing to be concerned about.  Immature Moths are caterpillars.  We are actually a bit envious as we have never seen either species at our Mt. Washington, Los Angeles offices.  The related Striped Morning Sphinx and Carolina Sphinx are the only aerodynamic Hawkmoths that visit our own porch light.  We will see if Bill Oehlke can confirm our identification.  He may request additional information on the sighting location to include in his database of Sphingidae sightings in North America.

Hi Daniel,
There is very little to separate saliceti from cerisyi. Even the diagnostic feature that some use with the hindwing eyespot is not 100 percent consistent.
Generally saliceti is more of an orangey-brown to brown species while cerisyi is more grey brown to brown. The specimen in question seems to have quite a bit of grey so I am leaning towards cerisyi for that reason. I also feel the location is a bit too far north and west in California for it to be saliceti.
Although Tuttle maintains a distinction between the two species, he indicates that further research may prove them to just be variations of the same species.
I will send a copy of this to Dan in Los Angeles County, and will also request a larger image and permission to post.

Bill and Daniel,
Great feedback from you both.  Thank you.
From the websites you shared I am 95% sure it is the cerisyi.  It was very grey…like old paper.  I have a large willow in my yard with the branches hanging down right by the window where it showed up.  As I mentioned there were 2 mating and they attached motionless for 12-24 hours.  They were gone this morning so no chance for a picture of them both together.  I am aware baby moths are caterpillars.  I am concerned that the larvae and then caterpillars may take to feasting on my willow tree.  If I see a large group of eggs, I will let you know.
Here are a couple more shots.  It is with my blackberry camera so apologies for the lack of quality.  You have permission to post.  The one with the ruler is fro the inside of the house.  the perspective is off, it was bigger than what it shows as the tape measure was closer to the camera.  I also include the original shot here.
Best,
Dan Yokich

Thanks for the additional information Dan.  We can’t imagine the caterpillars doing any lasting harm to your willow tree.  We would implore you to allow the caterpillars to feast should they happen to hatch on your tree.

Understood. We had a issue with butterflies laying thousands of eggs on 10 to 15 boughs. It was a mess with black caterpillars falling down and stripping long lengths of branches.
This sounds much different with just a few eggs here and there.
We will let them feast.
Dan

Since your tree is a willow, we expect the butterfly that laid eggs on your tree was a Mourning Cloak.

tiger moth ?

This moth was hugging a clump of dwarf umbrella plant, probably waiting for the sun to come out after the overnight rain.
Looking at the pictures afterwards I noticed it was hanging from its front legs with the other legs stretched.
I think it’s a tiger moth. I do remember finding a fairly large reddish-brown chrysalis a month ago but didn’t think to take a photo. I wonder if it overwintered in that.

Striped Morning Sphinx

Dear Laurentiu,
What a beautiful Striped Morning Sphinx or White Lined Sphinx.  We see several each year in Mt Washington, but our north facing garden is still too cold to expect them to be flying.  We expect to begin to see Striped Morning Sphinxes at the porch light and resting on the screen door on the first warm and sunny days after the rain ends.
