Southern Illinois is home to three large darter species in the Catanotus subgenus that do not occur elsewhere in the state: Spottail Darter, Stripetail Darter, and Fringed Darter. I wanted to photograph them and Ben Cantrell from Peoria, also wanted to catch this trio. Sarah happens to have a friend nearby she wanted to see. Win-win all around, we decided to make a weekend trip. We all drove as far as we could Friday after work. Sarah and I crashed in Benton, while Ben made it all the way to Cave-In-Rock. The plan was to convene bright and early Saturday morning around Iron Furnace. Iron Furnace is a massive stone iron smelting structure hidden within the Shawnee Forest, a mini Mayan temple of sorts within the Shawnee. It’s hard to miss.

I have caught large Catanotus relatives within the highland rim of Tennessee in the past. They were easily seined in riffles with large flat cover stones. These fish have egg mimics and are cavity nesters. In March, males find room under these cover stones, form a nest, and keep guard. Females deposit eggs on the underside of the nests’ cover stone. This trip, the streams were chert filled, Ozarkian-like streams lacking riffles with the key cover stone ingredient. The only large rock was along bridge embankments for stabilization. It’s less than kickable, but Ben had this figured out already. A tiny hook and bait dropped at the edge of each rock would determine if one was hiding underneath. If occupied, a curious male would dart out and grab the bait. Ben makes it look easy. He’s also a ninja with a dipnet, somehow managing to capture a tuberculate Creek Chubsucker.

Fringed and Spottail darters are nearly identical. In fact, it was thought both populations in Illinois were Spottail Darters until 1998. The two are only differentiated by the egg mimic growths occurring on the soft dorsal fin of males during spawning season.

At one location Ben and Sarah went off and fished further downstream while I photographed. They ran into a mess of redhorse, catching both Golden and Black. They were even tuberculate! Good thing I packed the medium photo tank, just in case. A Golden Redhorse was photographed, knobby snout and all. Ben was after a Black Redhorse for his microfishing species life-list.

Sarah & Golden Redhorse

That evening we camped at Horseshoe Lake State Fish & Wildlife Area. We arrived at dusk and setup shop. Ben pulled out his camping stovetop and we pulled out our travel cookware. I got to chopping and Sarah started cooking whatever was grabbed from the kitchen on the way out…potatoes, onions, celery, asparagus, bouillon cubes, flour, eggs, and chorizo. Final result: A gourmet, savory dumpling stew. Illuminated by headlamp. Enjoyed by all.

Ben split for Kentucky the following morning. Sarah and I meandered northward, stopping to capture Slender Madtoms and visit with a friend, Amber. Slender Madtoms were easily found, along with a bounty of Orangethroats, Rainbows, and strange darter hybrids of the two. Up the road was a small strip from a remnant logging community that is now a hippie’s dream of random art and exceptional custom craft stores. The girls did a little browsing, soaking up the local creativity then tried their hand at seining which ended up being a lot of splashing and catching up on life.
