In an attempt to obtain more contacts, I would like to add that A.
argyrospilus is also known as the fruit tree leafroller. It can be
extremely abundant in apple orchards in the east, or oak forests to the
south (also baldcypress in Louisiana- anyone there?). A. mortuanus looks
exactly like fruit tree leafroller, except that it is darker. It may also
be found in apple orchards, often together with argyrospilus. Both are
know to occur together in New York state (anyone there?). I am certain it
occurs in other localities in the New England states.
A. myricanus and A. eleagnanus occur in southern Canada, and are virtually
indistinguishable from A. argyrospilus. Just catch a bunch and leave them
to me to sort out!
They are flying now!!
A big thank you to all who have responded so far!!!
