[Odonata-l] Female Ophiogomphus Follow-up

[Bryan Pfeiffer]

Greetings,

Many thanks for the advice so far (on this list and in private emails to 
me) on the female Ophiogomphus from Vermont that I've been struggling to 
identify. Most interesting is that, based on my initial posting of photos 
of the subgenital plate and occipital region 
(http://www.wingsenvironmental.com/ophio.html), three of the continent's 
top odonatologists each tentatively identified this specimen differently -- 
as O. mainensis, O. carolus and O. rupensulensis.

I haven't had this much fun from a listserve challenge since a colleague 
and I here in Vermont located one of the notorious identification 
challenges in all of North American birdwatching -- a first-winter Thayer's 
Gull (http://www.hforcier.com/gull2.htm).

In any event, I've now got a great excuse to get back to the Ophi site this 
year. Thanks again. The gate remains open for your opinions.

Best,
Bryan Pfeiffer
