Happy Holidays!

December 28, 2021

I’m on a weeklong break for winter vacation (Christmas and New Year’s Day). I’ll be back on Tuesday, 04 January 2022 with a new post. See you next year!

It’s challenging to get all of the parts aligned for an image like this. In this case it’s close but not perfect. It would have been helpful to compose the shot with my camera tethered to a computer that features a larger screen than the one on the back of my camera.

All of that being said, the slight imperfections don’t diminish the visual impact of this image: Comet Darner (Anax longipes) exuviae are much larger than Common Green Darner (Anax junius) exuviae!

Relative size of exuviae from Anax junius versus Anax longipes.

This is the only photo I’ve added to my Odonart© Portfolio recently. I love this beautiful specimen!

Annotating images adds value, and I think it’s an under appreciated art form.

Sanford M.I.A.

August 7, 2020

Regular readers of my blog might be worried that I fell into a tethered shooting black hole. I did. Fortunately I was able to use the tether to pull myself to safety. Whew, that was a close one!

But seriously folks, I’ve been busy checking and double-checking settings so I’m not guilty of spreading misinformation. Promise to publish a rare weekend post filled with lots of tethered shooting tips and tricks that will make the wait worthwhile.

Notice the Zebra’s proboscis is extended and inserted in wet mud and sand along the shoreline of the river.

Adults take nectar and (males only?) take fluids from damp sand. Source Credit: BugGuide, Species Eurytides marcellus – Zebra Swallowtail – Hodges#4184.

Reminder: New schedule

November 11, 2018

Effective 29 October 2018, blog posts will be published on Monday, Wednesday, and Friday every week.

Please revisit my blog on Monday, 12 November 2018 when the next scheduled post will be published at 4:00 am EST.

New schedule for publishing posts

October 28, 2018

Regular readers of my blog know that I publish a new post every two days. That way readers aren’t overwhelmed by the stream of information, and I’m not overwhelmed by the demands of publishing a post every day. Plus I like to follow a regular schedule.

I decided to tweak the schedule for publishing posts slightly. Beginning on Monday, 29 October 2018 blog posts will be published on Monday, Wednesday, and Friday every week.

So if you were expecting to see a new blog post today (Sunday), then please revisit my blog tomorrow (Monday) when the next scheduled post will be published at 4:00 am EST.

Eye injury

January 31, 2018

A Blue-faced Meadowhawk dragonfly (Sympetrum ambiguum) was spotted near a vernal pool at remote location in Huntley Meadows Park, Fairfax County, Virginia USA. This individual is a male, as indicated by his terminal appendages.

When I post-processed the RAW images of the male dragonfly I noticed he has an eye injury, highlighted in the following annotated image.

(See a full-size version of the original photo, without annotation.)

The eye injury can be seen in two more photos of the same male.
