Orange Shadowdragon Neurocordulia xanthosoma

Description

Female Neurocordulia xanthosoma

Todd called me and told me these were popping up everywhere by the sandbar on the river. I had searched the area yesterday and found one but was unable to get a photo and then ran into inclement weather (it was later in the afternoon anyway).

As I made it there I saw he was indeed correct--they were all over about ankle to mid-waist height, perching in the brush along the sandbar and riverbank. They were easy to see as you walked by and kicked them up but hard to follow and see where they landed.

Of the three I was able to visually trace, this was the only one I was able to get close enough to get shots of and it was primarily through grass. I approached closer and tried to maneuver around the brush but she fled before I got any decent shots.

Overall a very frustrating but enlightening experience as I spent about five hours over two days scanning for the area for this species, wanting to get some basic in situ shots (it showed up readily at the moth lights). I slipped in the mud climbing a hill and came crashing down on my wrist with all my weight, injuring myself. The second day due to my own irresponsibility not replenishing fluids I ended up over-exerting myself very early in the hunt and having to cut it short.

At least I have a better idea of what to expect with this species next time as this was the first time I was able to observe it and see some of its habits.

Immature male Libellula luctuosa

Very common along the river, most common libellulid.

I think Neurocordulia xanthosoma may have been even more common but they were extremely hard to spot and spooked easily making it difficult to get shots representing their abundance.

Male Brechmorhoga mendax

I found where this male was perched and slowly became acclimated with the environment by standing still and only moving my eyes, basically trying to look like a well-dressed tree. He took off and returned in a similar location a few times and eventually perched low to the ground. The tripod and camera partially obscured my form and I was able to slide forward on my knees inch by inch until he was less than a two feet away.

I still was unable to obtain a truly lateral shot but this was the best attempt yet.

Male Nasiaeschna pentacantha corpse

I had just been marveling at all the exuviae I found in a very small section of the ditch that was shaded when I came upon this dead male. He had floated down from upstream but gotten stuck on these branches.

If you look closely at the abdomen you can see some mesoveliids, including a pair mating on top of his abdomen.

1. In situ, caught in branches in drainage ditch.

2. Sporting some kind of blue digital camo on the eyes. It was hard to hold it still in one hand and shoot so close but my goal was to show the hexagonal facets of the eyes...you might have to imagine it.

3. Lateral thorax, protruding frons begetting the common name for this species.

4. Terminal appendages, though I see things up close all the time I'm always amazed how much hair they have to aid in sensory perception.

5. This male likely had complications emerging as the right hindwing never fully expanded and is fused to the abdomen (where it looks like fishnet). This could've been pre- or post-mortem. Follow that right hindwing to the thorax and you can see where the thorax is ripped open and flight muscle tissue exposed.

Judging by the lack of ingress and intact muscle I think this dragonfly probably beat its wings so hard and repeatedly that it tore its own body straight open attempting to fly. I could also be incorrect but I feel like any outside source that would be capable of inflicting that kind of damage (like a bird) would ultimately consume the dragonfly.

From the overall good condition of this dragonfly I think it likely died of exhaustion. It could've also been impaired by spider venom. I guess it's impossible to know. I put him back in the water and let the decomposers get back to work.

I saw this fly while climbing down by the rocks adjacent to the river and looking through the brush for odonates. It was so large I mistook it for another insect at first and could hear its wings buzzing as it flew by me.
