I too am gratefull for your photos.
To elborate on my ideas. I beleive that in our colder climate that some boreres pupae overwinter and hatch in the spring, different then the regular cycle of hatching in fall and laying eggs at that time. I disscused this with Bob Hollingworth ( an entemologist sp?) in some detail and he indicated that the evidence that I had would support such a theory. I havn't followed up, as you have, with capturing some pupae and holding them over. I really should do that to see if I can get some moths that hatch in spring.

I
posted a bunch of borer images last year, but I can't figure out how to
send a good, small image to the list - my software changed when I got
the 'new' machine. So there are bad small images instead.
Chuck
Chapman and I have been comparing our borers' activities back and forth
over the last couple of years. His feelings on the hatch process
were different from mine, but I'm coming around to his viewpoint - that
there are two distinct cycles, one in the early spring (May around
here) and one in the late spring (mid June). As opposed to two
generations within the same year.
That
certainly is a borer moth btw, and the best image I have seen to
date. I've tried saving the pupae (successfully) in order to get
an excellent image of the moth, but they always beat themselves to
death first.
Special surprise for the end of
the year... we have snow and frozen ground! It's one thing to
have a green Christmas, quite another to have thawed ground as well.
Best regards,
