almost all of those shots are severely vignetted (in this case, corners lightened), so completely worthless.

Re: Vignetted

Nope, I use Photoshop, but too extreme to fix. Thank goodness I took some shots with my 35mm, until now I have been quite happy with my 24mm.

Lilypad Clubtail
This is a male Arigomphus furcifer, the Lilypad Clubtail. This species prefers ponds and lakes with some sort of plants with floating leaves. Most of the Clubtails, Family Gomphidae, are stream specialists but there are exceptions to that general rule. A. furcifer is a species I have wanted to photograph for years.

I had to wade out to chest high depth to get close enough and then waited while this male landed on other lilypads too far away to shoot. The first time he was in range a female showed up and the male flew up and grabbed her and then they flew off out of sight while they mated.

This was at Spaulding Pond, Jackson County, Wisconsin.

This is an Erpetogomphus disignatus, (the Eastern Ringtail), female in an uncut barley field at the Hardware River Wildlife Management Area, Fulvanna County, Virginia, 9-Jun-17.

It was partly cloudy and whenever the sun was hidden the dragonflies would perch in a mostly horizontal posture. There were dozens of dragonflies of several different species hanging out in the field. This was about 1:30 pm and the temperature was in the 90s.

Within seconds of the sun hitting them, they repositioned themselves with their abdomen pointing directly at the sun to limit the surface area exposed to direct sunlight. This behavior is known as obelisking.

This is a male Erpetogomphus disignatus.

At this time Odonate systematics recognizes around 22 Erpetogomphus species. I say "about" because we are unsure if several closely related species/populations are sub-species or unique species. They are different enough that we take note of it, but we don't know for sure if they are in the same individual clade or sister/parent/offspring clades. Eventually, maybe a grad student will spend a year or two studying them and find out.

Complete waste of time and money!! Any Creationist could tell you that they are all the same buggy kind. Lol.

Great pictures again! I appreciate that you waded out in that brackish water just for me.

Metamorphosis
I was lucky one morning in Virginia to find a Hagenius brevistylus male going through metamorphosis and emergence from the nymph stage to the adult stage. This is the largest North American species in Family Gomphidae. H. brevistylus preys on other dragonflies, hence the English name the Dragonhunter.

The reflections on the wings demonstrate that they are not flat, but offset and braced in such a way as to provide longitudinal strengthening without adding additional mass. This gives differential flexibility from base to tip and from front to back and is the key to the acrobatic flight abilities of odonates.

The cast skin of the nymph is called an exuviae.

This is a female from a post last year. Dragonfly adults normally take a week or so of feeding and flight in the sun to get their mature coloration.
