Hard to take a picture of something made out of air (like a heat dome), so here’s one of an airborne activity happening at Owl Acres on a hot summer morning. A large quad drone is being used for aerial chemical application to the adjacent cornfield. The aircraft flies a pattern over the field, controlled by a computer and guided by GPS. It’s applying a broadleaf herbicide that kills every plant in the field that’s not corn, and a broad-spectrum (pyrethrin) insecticide that kills every insect it touches.

Too Darn Hot: Heat Dome

Updated September 11, 2023

For several days this summer, the temperatures climbed into the high nineties during the day and stayed in the high seventies at night. Days like that are the worst of the summer days. The humidity is so high that when I walk out of my air conditioning into the heat, the air feels alive as […]

Soybean pods covered with fine hairs hang in clusters from central plant stem

Farmer’s Fixation: Soybeans

Updated September 7, 2023

The little field across the road from Owl Acres is planted in soybeans this year. Last year it was corn. It’s late summer now, and the soybeans (Glycine max) are beginning to dry and change color. Green leaves and stems are turning yellow, and the pods hanging from the plants are darkening to brown. When […]

Dew-covered Japanese beetle sits on a Virginia creeper leaf, waiting for the morning sun to dry it off.

Skeletons in the Garden: Japanese Beetles

Updated September 4, 2023

There’s a bunch of Virginia creeper growing on the fence down by the barn. Many of their leaves have been surgically stripped of the softer tissue between the veins, leaving lacy skeletons behind. A closer look reveals the culprits–a dozen or so half-inch-long, metallic green beetles with copper-colored wing cases and little white tufts of […]

Large shade tree stands in a green yard, towering over the author’s red house. Siberian Elm.

A Gift from the Gobi Desert: Siberian Elm

Updated August 31, 2023

There’s a clump of four trees in the front yard on Owl Acres just outside the dining room windows. I often hear birds singing and squirrels chattering from these trees, even in the winter. There’s also a two-foot-tall seedling in the garden space. These trees thrive in several other places on Owl Acres and are […]

Green field of corn and distant valley against a bright morning sky, viewed from the open doorway of the hay mow of the author’s 1915 timber frame barn. A couple of bales of hay lie in the foreground.

Magnificent Monoculture: Corn

Updated August 28, 2023

The air is full of that sweet, fresh scent of ripening corn. You can almost hear it growing. It’s been a staple on and around Owl Acres for 170 years. Today the fields across the fence are lush, with ten-foot-tall stalks in neat rows. Broad green leaves ripple in the breeze, sending waves undulating across […]

Soil Part 6: Mycorrhizal Fungi

Updated August 24, 2023

Wherever I walk on Owl Acres, there’s a living web under my feet holding it all together. That web is created by a particular type of fungus called mycorrhizal fungi. Sometimes they pop up various varieties of mushrooms like the beloved morels, but generally they are busy doing other things. Mycorrhizal fungi consist of a […]

A small, brown cricket with bold stripes, long antennae and two “horns” (cerci) at the rear of its abdomen, sits on a blade of grass. A Brown Trig in the author’s yard. Not certain ithis one is a Say’s Trig (Karen is not an entomologist), but there’s a bunch of them. 2 or 3 jump away at every footfall.

High Summer Singer: Winged Bush Cricket

Updated August 21, 2023

Stepping out in the afternoon of a hot summer day, I am surrounded by the songs of the insects. They’ve taken over from the birds to create that distinctive and to me beloved soundscape of high summer. As I listen, I wonder—what is that high-pitched, almost at the edge of my hearing, trill that overlays […]

Close up photo of a brown, segmented critter with elliptical, flattened dome-shaped armor. Wood louse, pill bug or roly poly, pick up a piece of wood that’s been in the dirt for a while and there she’ll be, with a bunch of her closest friends and relations.

Soil Part 5: Macrofauna

Updated August 17, 2023

Macrofauna are the larger critters living in the soil on Owl Acres. We are familiar with most of them. Millipedes, centipedes, true spiders, ants, earthworms, certain beetles, harvestmen ( AKA Daddy Longlegs) wood lice, termites, slugs, and snails. Along with these soil lifers, larvae and nymphs of many insects live and grow in the soil […]

A large tree trunk goes away vertically and spreads into a green canopy high overhead. A portion of the author’s barn red house is visible nearby. Boxelder has stood on this old farmstead for more than 50 years.

River Maple or Boxelder Tree

Updated August 14, 2023

Half of Owl Acres is given over to a forest reserve for tax purposes, but more importantly, woods for habitat purposes. The woods run along the west and north sides of the property and make a good windbreak as well. There are several types of trees in the woods, including quite a number of boxelders. […]

Tiny arachnid with 8 legs. Front legs are tipped with heavy claws like those of a crab or a scorpion. Little guy lacks a stinger.

Soil Part 4: Mesofauna

Updated August 10, 2023

Continuing with the plan to divide the animals that live in the soil by size, we come to the meso or middle-sized fauna. Whereas the microfauna we met—protists, nematodes, water bears and rotifers—live in water in the soil, the mesofauna we’ll look at live in air-filled pores in the soil. Now we’re starting into the […]
