It’s always interesting to see what is out at different times of day. Some species we saw during this first afternoon were not seen the following morning, and vice versa. Where they like to hang out (e.g. on the open sandy areas versus in the dense riverside vegetation) has a lot to do with it, I think. It gets too hot in those open areas during the afternoon, so the species that prefer those habitats are most visible during the morning; shaded areas are too cool during the morning for those species that prefer that habitat, so they seem to be absent until the warmer afternoon. This is not universal, of course, but it seemed to be the rule for several species.
Here’s a selection of what I photographed at Punchbowl Landing:
|Male Great Blue Skimmer (Libellula vibrans). There were many of these around, but this was the only one that appeared largely mature.|
|Male Blackwater Clubtail (Gomphus dilatatus). As the English name suggests, its preferred habitat is blackwater (tannic-stained) streams. I did not see many of this impressively clubbed clubtail, and this was the only one that sat for photos. I just wish it was in a better spot.|
|Male Turquoise Bluet (Enallagma divagans). A fairly common stream species in the region. Note the all black top of the abdomen except for the two segments near the tip. There are a few bluets in the east with abdomens like this, but none west of the Rockies.|
|Male Florida Bluet (Enallagma pollutum). This one was quite a surprise and I didn't realize what it was until I looked at my photos closely that night. I presumed they were Orange Bluets (E. signatum, a rather common and widespread species in the east), but once I looked closely at the abdominal appendages I realized it was the very similar Florida Bluet—a new speciesfor South Carolina and a substantial range extension. Here's the OdonataCentral map—my record is the isolated green dot in South Carolina. This species is likely overlooked in other areas (like Georgia and probably North Carolina or even further north) where it is confused with the Orange Bluet. These were not out until almost 2:00 PM—I know, because finding more was the primary motivation for returning the next day and I looked pretty intently. Not being active until later in the afternoon—at least at the water, is typical of the non-blue bluets.|
|Male Blackwater Bluet (Enallagma weewa). Like the clubtail above, this is another species that has a preference for those tannic-stained streams. This one really sticks to the shade where they are difficult to spot and photograph.|
|Female Swamp Darner (Epiaeschna heros). I was very fortunate to see this one hang up during the morning coolness and she was extremely cooperative!|
|Male Gray-green Clubtail (Arigomphus pallidus). These were primarily seen sitting on open sandy areas near the river, but only during the morning warm-up. This was the first time that I had seen this species, and it was definitely a highlight for me.|
