alien or not?

[Woody Woods]

Thanks for the Holland's input-- I really should hunt down one of those
apparently invaluable books.

It turns out that Lynn Scott, who answered me offline, had taken a photo of
A. Punctella to the Canadian National Collection in Ottawa while on a
different mission; the folks there, including Dr. J. Donald Lafontaine-- to
whom I have not yet written-- referred to it as native, but said that the
host species prior to the arrival of Ailanthis was not known.

The friend who took the photo (I'll find out what kind of camera, Jim-- I
don't know) maintains a website about alien plant species, and says that
Ailanthus came here in the late 1800s, and was first introduced to
Nantucket, where the photo was taken, in 1913. She has since found that A.
punctella was first recorded there in the 1920s, according to Johnson,
Charles Willison. 1930. A List of the Insect Fauna of Nantucket,
Massahusetts. The Nantucket Maria Mitchell Association Vol. III no. 2. 174.

Anyway, perhaps after a few more communications we might have a better idea
of whether there is a hitherto unidentified hostplant for A. punctella.

By the way, Lynn mentioned that her photo of punctella was a first sighting
for the Ottawa area, and that Ailanthus is not found that far north.

Holland's book (1903) shows two different species of Atteva.  But on the
Natureserve web site, the genus is listed as monotypic with that species
name (punctella).  I found no mention of point of origin, but it reasonable
to presume it followed its host plant into North America.  Nice picture!
What was the camera used to take it?

A friend found this Ailanthus Webworm moth (Fred SaintOurs is pretty sure
it's Atteva punctella-- do you agree?). It was on an Ailanthus altissima
sapling on Nantucket (off the coast of Massachusetts).

She can find no confirmation as to whether this moth is alien or native. Do
any of you know? Ailanthus altissima is Asian in origin, and such
information as she has found so far makes no mention of any other (native)
hostplant.
