Northwest Dragonflier: ID Challenge #5 Answer
http://nwdragonflier.blogspot.com/2013/09/id-challenge-5-answer.html
Tuesday, September 3, 2013. ID Challenge #5 Answer. I didn’t give you much to go on in this challenge, but this odonate is identifiable based on what you see. Not only that, but the sex can be determined and, as I alluded to, a little more can be deduced—something that has happened to this individual, if you’re observant. Needham, Westfall, and May, 2000). See Figure 80 on page 159. Males of the species lack those projections, and the rear margin of their occiput is smooth and slightly concave...Below...

Northwest Dragonflier: Odonates in The Pearl: Tanner Springs Park
http://nwdragonflier.blogspot.com/2015/06/odonates-in-pearl-tanner-springs-park.html
Saturday, June 13, 2015. Odonates in The Pearl: Tanner Springs Park. Tanner Springs Park is not your textbook city park. It’s a great example of melding “wild” natural, “tamed” natural, and unnatural elements in complementary ways. About two-thirds of the park are what I would describe as unkempt—which is a good thing. It isn’t all manicured lawns, ornamental vegetation, and fountains. Check out the view. An artificial spring and source of one of the tiny streams flowing into the pond downslope. The fork...

Northwest Dragonflier: March 2012
http://nwdragonflier.blogspot.com/2012_03_01_archive.html
Sunday, March 25, 2012. My new odonate nymph digger. Posted by Jim Johnson. Tools of the trade. Monday, March 12, 2012. Once in a while I’ll see someone refer to “dragon flies” or a “dragon fly” which causes a brief piercing sensation in my head. Just kidding—it’s more of an open-handed thump to the back of the skull. Just kidding again! It really isn’t a big deal, but I thought I would explain the protocol regarding whether the fly. Part of the name is separate or not. Posted by Jim Johnson. My new odon...

http://nwdragonflier.blogspot.com/2013/08/whats-that-little-blue-thing-northwest.html
Friday, August 23, 2013. What's that little blue thing? Oh, the little damselfly that has a blue thorax with black stripes and an alternating blue-and-black pattern on the abdomen? S a bluet. Which one? A generic Pacific Northwest bluet ( Enallagma. With an alternating blue-and-black pattern, the thorax with blue. And black stripes, and blue postocular spots on top of the head.

Northwest Dragonflier: December 2012
http://nwdragonflier.blogspot.com/2012_12_01_archive.html
Thursday, December 6, 2012. ID Challenge #4 Answer. Click image for a larger version. Ready for the solution to ID Challenge #4. Let’s start at the top as we consider this mystery Pacific Northwest odonate: Is it a dragonfly (Anisoptera) or a damselfly (Zygoptera)? Probably most people can take a glance and immediately recognize it as a dragonfly, but how do we know for sure? I did a while back on differentiating dragonflies and damselflies which illustrates the head/eye shape. Posted by Jim Johnson.

Monday, April 30, 2012. Lake Martin, Louisiana, Revisited. I leave Louisiana tomorrow morning to make my way to the Dragonfly Society of the Americas annual meeting in South Carolina, but I was able to make another visit to Lake Martin a short distance outside of Lafayette.
