Geometrid Moth

Pieridae butterfly?
Hope I don’t become a pest :-), but I have another for you. The closest I’ve been able to come on this little guy is that it may be a Pieridae of some kind, but I haven’t been able to zero in on the exact species. (The hindwing damage is my fault, I’m afraid.) Any suggestions? BTW, corresponding with you has inspired me to start a virtual collection. I’m going to keep my digital camera handy and begin to accumulate my own image library of insects, spiders and bugs. I know your site will be a crucial resource in helping me ID all of them. Thanks for your help, and I’ll try not to bother you too much.
Oh, and one last thing. Thanks for referring me to the Northern Prairie Wildlife Research Center website ( It’s remarkable. I’ve been in contact with them as well, and I’ve brought some of my finds to their attention after I found that there they do not yet have a record of those species being spotted in my county. I’d like to urge your other site visitors to consider doing the same. I was a wildlifer in college (though I never got the opportunity to use my degree), and it’s a good feeling to be able to add in some small way to the body of scientific knowledge.
Thanks again.

Hi again Larry,
Your latest image is actually a Geometrid Moth, possibly what Holland identified as Dyspteris abortivaria. It is common in the Appalacian regions.
