Although I hung about the Cavern harbor area for the better part of a day, I saw no fish or sign of fish, heard no suspicious splashing, saw no likely rippling in the water. So I had to accept defeat for now and add this to my growing list of long-term zoological projects. But since I was already here, I thought I'd follow in larryf58's footsteps in search of the elusive Cavern Firefly. So off I went.
Similar to larryf58's observations, I could find none in Ae'gura itself, but found several in the neighborhoods Bevin, Kirel and Seret. They all seemed to be of the same species, similar in behavior to the solitary Fireflies in Direbo. The Cavern Firefly is yellow whereas the Direbo is white. However, since the lighting in each location is significantly different (though relatively dim in each), it likely would take more study to be sure their coloration truly was different, and to determine whether or not they were related or separate species.
Here is a Cavern Firefly in Bevin:
Another one:
Kirel:
And another:
And finally Seret:
Yet another:
I got to thinking about all the other varieties of fireflies seen in other ages and decided I needed to hunt down those I hadn't yet observed myself. I was very interested in figuring out if any of them were related or if each age contained its own unique species. So I was off to Todelmer first.
Just as larryf58 had already observed, there were solitary bright green fireflies throughout. Though they were not numerous enough to be found at each light, the location of the Todelmer observatories themselves atop the natural rocky columns made it difficult to judge whether fireflies might be found in the forested land far below, and if so, if they would be more plentiful and less solitary there. Altogether, I found solitary fireflies in eight different locations in Todelmer.
The path circling up the side of the large stone column housing the main observatory begins at the linking bubble. A short distance from there on the upward stairway, I found the first firefly:
About a quarter of a circuit on the path farther up, near the metal stairs, I found the second:
The third was about halfway around again:
The fourth was just before the final flight of stairs to the observatory itself:
The fifth was along the observatory perimeter at the stone column top:
Traveling to the secondary observatory, I found a sixth on the path ascending from the shuttle:
The seventh was at the apex of this stone column, again along the perimeter:
And the eighth was there as well:
I concluded that all eight fireflies I'd found were the same species.
I hadn't yet visited Kadish Tolesa, having assumed that in spite of the plentiful birdsong, I would be unable to observe them any better than in my prior visits. The canopy of the enormous trees there is so very high that one can only see mist above. And the trees themselves are so massive and grow so thickly together that it would be a serious undertaking indeed to figure out how to scale them. Nothing short of carving out stairs or bringing serious mountain climbing gear would do the job; and at this point, I honestly wasn't up to either approach. But in checking with the D'ni Zoological Society records, I noted that fireflies had been reported there. Although I had never noticed them in my prior visits to the age, I headed there next to continue my firefly study.
Happily, I did find solitary fireflies in four different locations. I concluded that there were at least two species of them; and possibly three. One variety is blue, another is white and all are solitary. Yet the blue can be found only in the wide open vista near the pyramid, whereas the white are found within the dense forest itself. Out of the two examples of the white variety, one clearly was attracted to light whereas the other seemed apathetic; so it was going to take significant further study to determine whether these two were related or not.
The first white firefly was cruising about one of the lamps along the forest path:
The second white firefly was near the rotating tree trunk, buzzing about in the shadows:
The first blue firefly was flying solo near the exit from the forest:
The second was not far away, at the edge of the landing near the stairs leading to the pyramid:
So far as I could tell from my own recollections and the DZS records, I had visited all the ages known to contain fireflies. Now it was time to try to sift through all the information. I decided this would best be started by creating a grid of my data:
As an afterthought, I added the Cleft caldera flies to the list. Rils had made a good point, that they could well be the same insects seen in Direbo, looking different only because of the dramatic difference in lighting between the two locations.
Whew, what a chunk of work! Firefly research obviously could become a full-time job, there are so many varieties and so many unanswered questions. But for now, I must leave such work to others, as my surface life and obligations were beginning to call.
Next: Kadish Tolesa concluded
