Small White Moth

Small White Moth
Santa Rita Experimental Range, Santa Cruz County, Arizona, USA
July 24, 2013
Size: small
Came to lights at gathering_2013. Thanks for any help with ID.

Sorry for the confusion - this isn't an Arctiine.
Moved from Tiger Moths. I suspect this is an undescribed Megalopygid near Norape.

.
I apologize for the mess! Since the Eacles oslari looks to be a female, I would estimate the width of the forewing to be about 32 mm and the WS of the white moth in question to be 20+ mm.

I hope you all get it figured out. Kyhl, I don't know how to unlink the images or I would do so.

 
Wingspan of white moth
We think your estimate of the wingspan is about right based on our recollection of the size of the moth.

Thanks for all your effort in trying to ID this little guy.

Well, maybe I got something right! Thanks.

Moved from Browntail Moth. This is NOT Euproctis chrysorrhoea. It is an Arctiine. My vote is for Euchaetes helena or perhaps a Cycnia. I'm not quite sure.

 
There are still two more of these
on the Euproctis page. Click on data and on Arizona to see them. We're guessing they are all the same, whatever they are.

 
Thank you
I did not see those two. Neither are Euproctis chrysorrhoea. I am not sure what they are, though.

Are there really Browntails in Arizona?
We can't find any records for that. Might this be something like Leucanopsis perdentata or some Euchaetes or Pygarctia? We're not saying we know what it is, but it doesn't look like the other Browntails and seems to be much smaller??

 
.
Well, you raise a good question and the answer is I don't know but since it was imported once I suppose it could have come in again but if so no one has reported it off of the NE coast. It still looks like a Browntail to me but now I notice that the fuzzy body on the closer picture has a white tuft at the end of the abdomen.

You must have looked long and hard for your L. perdentata suggestion. I agree it is the most possible of the Lichen Moths. I went through all of the Lichen moths and here are my observations: Parachutes,Euchaetes, and Pygarctia all have smoother bodies and black legs and less "hair" on their heads. I have been paying close attention to these species because I have been raising some thinking that some look different from what I see posted. I have never seen them to have an abdomen like the one in the pictures.

As for size, it would be interesting if John knew the identity of the large moth next to this one. Your suggested species does not solve the size problem since Maury Heiman's information says that the female WS is 55 mm and Browntails are apparently 36-42 mm.

My only other suggestion might be a Fall Webworm which flies March-August and is sized at 25-42 mm. They have black and white stripped legs and I cannot tell if these are stripped or not.

It looks like most of the possibles are from Jeff Smith' Museum collection and have never been seen since.

Maybe we should just move them back to Moths!

 
Large moth with small white moth
We're following this discussion and have added another image of the large moth next to the moth in question. We don't know the identity of the large moth.

Hope this helps.

Moved from Moths.

Another nice one for you. It doesn't have the big plumed antenna but I assume it is a female. There just isn't anything else it can be.

A. Hendrickson,

Very happy to know what this is. Arizona is a great place for insects!

Thanks so much,

I think this is the same, but in resting pose:

 
Same moth?
John,

It looks like it could be the same, perhaps even the same individual.
