Thank you again for your wonderful site. I have spent way too much time, following paths of links through your interesting pages. But that isn’t why I’m writing.
It seems that we have just a could of kinds of dragonflies that we see frequently around our house, so I thought it might be nice to be able to identify them. Here is a photo of one of them that my son managed to have perch on his hand. From what I could find I thought it might be a Western Flying Adder (Cordulegaster dorsalis) but I’m NOT an expert yet!
The other thing that I think is really cool about several of these photos is the way that you can see hexagonal reflections on the eyes. That isn’t just in the photos – we saw that in ”real life” too. Is that because of the hexagonal structure of the ommatidium that the eyes are made up of?

Dear Mother and Son Bug Fans,
Thanks for your compliment.  Alas, we often have difficulty with species identifications for Dragonflies, but this might be
Cordulegaster dorsalis which BugGuide calls a Pacific Spiketail.  We like the name Western Flying Adder, but we don’t know where you learned that name.  Perhaps one of our knowledgeable readers can assist with this species identification.  We believe individual facets of the eyes are hexagonal.

Dragonfly (I think it’s a Blue Dasher). I’m wondering what the little red spheroids are. Are they insect eggs? Was it parasitized by something?

Water Mite Larvae on Dragonfly

Water Mite Larvae on Blue Dasher

Dear Joel,
Dragonflies are frequently hosts to Ectoparasitic Water Mite larvae that attach themselves to the Dragonfly while it is still an aquatic naiad.  The Northwest Dragonflier website maintains that when the naiad molts into a winged adult, the larval Water Mites in the genus
Arrenurus crawl from the cast off exuvia onto the still soft body of the winged adult and attach themselves as ectoparasites.  They derive both nourishment from this and the advantage of transportation to a new body of water where they can drop off and mature.  Light infestations do not negatively impact the Dragonfly much, but heavy infestations can be very detrimental to the adult Dragonfly.  Here is another simple explanation on Taos Telecommunity.  We believe you are correct that this is a Blue Dasher, Pachydiplax longipennis, based on photos posted to BugGuide

Thanks to you and your readers’ submissions, I have figured out this sweet backyard guardian is an ebony jewelwing damselfly (and a guy). He seemed to be making sure I didn’t steal the silver from the table, but when I brought out the camera, he turned into a ham. This sort of ”curtsey” is a kind of warning or territorial display, isn’t it?

Dear Elfie B.,
Thanks for sending this interesting angle on an Ebony Jewelwing.  We will try to research your question about warning or territorial display.

Just wondered what this might be. I posted it to your Facebook page but never got a response. Is it just a pretty dragonfly?
Thanks!

Possibly Scarlet Skimmer

Possibly Scarlet Skimmer

Dear Carol,
We are not certain, but this red Dragonfly looks to us like it might be a Scarlet Skimmer,
Crocothemis servilia.  According to BugGuide:  “Native from southern Japan and China to northern Australia. Introduced accidentally to south Florida and to Oahu, Hawai’i.”
P.S.  We do not respond to postings on the Facebook page as we have our hands full with the submissions that come directly to our website.  On busy days, we are only able to respond to a small fraction of the identification requests and submissions we receive.

Thanks!! You guys are the best!!
Carol

Dear Trina,
It seems we don’t get enough photos of the magnificent Green Darner Dragonfly,
Anax junius.  During the research of his book, Daniel unearthed 13 Maleficent Names for Dragonflies, and they include Devil’s Darning Needle, Ear Sewer, Ear Cutter, Water Witch, Snake Doctor, Devil’s Little Horse and Evil Old Hag’s Horse.  Green Darners are a migratory species.

Hi,
We found this bug while playing in Lost Creek. It acts like it wants to sting with its tail and bite. Should we avoid this creek and bug? Thanks in advance..

Dragonfly Naiad

Dragonfly Naiad

Dear Jerrod,
This is the aquatic larva of a Dragonfly, known, like other aquatic larvae of flying insects, as a Naiad.
  It will not sting and it will most likely not bite.  I has a highly specialized hinged mouth that expands and shoots out to snare prey while the naiad waits well camoflauged among the plants and aquatic debris.  Each species of Dragonfly, and there are many, has a distinctive looking Naiad, but alas we do not have the necessary skills to quickly identify your Naiad to the species level.
