Re: [nafex] Round-headed Appletree Borer

	Michael, thanks for the lead to such a fine article and up close and 
personal photos. I had no idea that some lived only under the soil line,  
That some are over 3"long.  That ideally one not have wild hawthorn within 
300 yards!   And  the idea of using old logs to attract and then burn seemed 
good.  I'd worry that coating a pile of logs with tanglefoot would kill just 
too many beneficials before  we could even get acquainted. Thanks again, 
learned a bunch.    Mn. Del
