Allegany Nature Pilgrimage – Dragons!

May 31, 2008 – Allegany Nature Pilgrimage – Dragonflies

Participants Posed for this PictureI couldn’t resist an afternoon looking for Dragons with Jeremy Martin.  I first met him at the Audubon when he was in the shop purchasing a dragonfly book…  We happened to be starting a new project with the Natural Heritage Program – a collaboration with the New York State DEC to do a state-wide Odonata Survey.  I found out that he already knew a good deal about dragons and damsels and he has turned out to be quite an asset to the project!  An engineer by trade, he does the dragoning on the side… and he does it with gusto. I wish I knew a tenth of what he knows!

Emerging DragonAnd I wish I had his luck:  As he was setting his books and equipment down near the site where the program was being held, there, right in front of his eyes, was a dragonfly emerging from the exo-skeleton of the larva.

Where some insects exhibit complete metamorphosis, dragonflies and damselflies (and several other aquatic invertebrates) exhibit incomplete metamorphosis.  In the complete version, an insect starts as an egg, hatches out as a larva, goes into a pupa, and emerges as an adult.  This is the classic insect life cycle that kids learn in school.  Insects that exhibit incomplete metamorphosis skip the pupal phase.  The last molt of the larva is not a pupa but the adult insect.

Exuviae - Three SpeciesThe shed exoskeletons are called exuviae (singular: exuvia).  We found several around the site – at least three different species: Common Baskettail, Springtime Darner, and Common Green Darner.

Jeremy was great about engaging even the youngest learner at his program.  Here, a young naturalist is using a landing net to scoop vegetation from the bottom of the lake.  He picks through the plants to find dragonfly larva:

The Wings Popped Open While I was Taking PicturesAs I was kneeling down to take a few more shots of our emerging dragon, its wings popped open.  Then, everybody wanted a picture.

Poor Toni.  The darned darner flew before she got her turn!

Luckily, Jeremy nearly netted another a few moments later.  Nearly netted?  Yeah… he knocked it into the water, then scooped it up with the landing net… not the normal way to catch a flying dragon!  Lucky, though, because it was stunned and allowed us to put it on some plants and take loads of pictures before it recovered and flew off.  And this time, Toni got her turn!

Here’s my shot of the Springtime Darner:

Thanks, Jeremy, for a great workshop!  Apparently, Jeremy had emerging dragons on his second program of the weekend, too.  I wonder if he contracts with Odonata Central and how much he has to pay to get larva to emerge on command?…

There are many sides to every story.  Pop on over to read other accounts of this same event:

  1. So glad that you could attend Jennifer! It’s so interesting reading others accounts of the same event, and your pictures turned out great. Thank you again for letting us use the nets; I just wish that had had been more dragonflies to use them on.

  2. Excellent – I’ve never been able to find the nymphs or larva, despite my searching. I guess I’ll just have to revise how I do it. Great views of the different stages, and a BEAUTIFUL Springtime Darner shot.

  3. I submitted a comment just before this, but I think I got ‘de-spammed’ again. It’s funny that if I’m logged into, I get blocked. Like this, no problems. I did report it to Askimet, though!
