Moving past the Woodland Trail Loop, I’m in the western section of the Falls of the Ohio State Park. It’s been more than a month since I last visited this area. One of my favorite trees is here and although I’ve already missed the prime leaf color moment…I’m hoping some autumn splendor remains. Along my walk I come across a driftwood structure that has been stacked teepee-style by other park visitors. I see this kind of expression regularly and there must be a kinship between this activity and piling and stacking rock upon rock. It’s satisfying to do and when you step back from your work…it’s obvious you left an impermanent mark in the landscape that says you were there. The tree I seek is just a short walk away and in no time at all I arrive on the scene.
This old Cottonwood tree with its raised roots looms large in my imagination and is my personal favorite tree out here. I’m sure I’m not the only one who feels this way because there is usually plenty of evidence laying around in the form of empty beer bottles, spent camp fires, and yes…the odd bits of furniture people drag to furnish the room that exists underneath the tree. I’ll wager for some…this is known as the party tree. I was elated to see that most of the junk (old tarps and a red couch) have been removed by some other purists. The Cottonwood tree had already dropped most of its leaves, but there were still a few hanging on. After resting a moment under the tree and admiring the distant view of Louisville across the Ohio River…I decide to turn for home. I was in the process of walking away when I noticed something moving along the fossil rocks. I froze to see if I could get a better look at the creature that was walking towards me. Naturally, my camera is at the ready!
Regular visitors to the Riverblog know that the Falls of the Ohio State Park is home to several out-sized insect species that have uniquely evolved here. All the different species are critically endangered and not to be harmed in any way. I was quick to identify this as the Golden Hour Ground Beetle. It was so named because it usually makes it first appearance of the day when the sun is about to set. Otherwise, it is nocturnal in its habits.
The Golden Hour Ground Beetle does not fly. It relies upon stealth and six strong legs to scramble across any surface. In form, it is not unlike the much smaller tiger beetles that also make the park their home. Unlike the smaller beetles, the Golden Hour Ground Beetle is a scavenger and not a hunter. I suspect this specimen was at the Cottonwood tree because it has learned to find scraps of discarded camping food here. This beetle has fairly large eyes that can gather the most meager light in the darkest of settings. It’s abdomen is banded with a coarse hair that insulates this insect during cold nights. As long as I didn’t make any rash movements, this giant bug was tolerating my presence.
I observed my new “friend” moving to the water’s edge to obtain a drink. I wondered if it had the ability to swim in its survival tool kit? I watched the insect as it searched all around the fossil rock shelves that were created by the river dissolving the old limestone away.
I came across a second giant beetle almost immediately after crossing the small creek that separates the western and eastern sections of the park. Male and females are virtually identical. There are gaps in our knowledge about their life cycle. This specimen was in the process of checking out a short, hollow log. I’m presuming that it was either seeking food or shelter? I think poking my camera through the end of the log spooked this one a little. It ran away, but didn’t go far. I kept my movements to a minimum and after a while it seemed to relax again.
I observed this 14 inch or 35.5 centimeter beetle relaxing on the exposed roots of a Sycamore tree. As the golden hour approached, the beetle stopped seemingly acknowledging this magic moment when everything is bathed in a warm golden light. I did the same watching the sun set before finding my vehicle in the parking lot of the Interpretive Center. To everybody in the wider world…have a great week.
