On a bright, cool morning in early July, the landscape is a vibrant, nearly uniform green. We’ve had lots of rain this year, and everything is lush and growing. Against this backdrop of vibrant green, plate-sized clusters of tiny white flowers buzz with happy pollinators. The flowers are arranged in flat-topped umbrella-shaped clusters ten to […]

Living Storage Tanks: Winter Ants

Updated June 9, 2025

Entomologists catalog over a thousand species of ants that live in North America, many of which live in Iowa on Owl Acres. Each species has its own fascinating way of doing life. Let’s take another look at the ants that have been crawling all over the peonies. They are called winter ants or false honeypot […]

Virginia Waterleaf

Updated May 5, 2025

We were out in the yard, inspecting the blossoms on the apple and cherry trees, when sprays of little lavender flowers caught our attention. A patch of Virginia waterleaf (Hydrophyllum virginianum) was growing next to the shop. The plants were about a foot tall with long, deeply lobed leaves. Clusters of flowers hung at the […]

I like my coffee immediately upon consciousness in the morning. That requires a fast coffee maker, which we have. It maintains a reservoir of hot water at all times and is ready with no notice to produce coffee. Recently, after eleven years of exemplary service, that coffee maker sprung a leak. Water began to pool […]

Asian lady beetle wintering inside the house on a sunny window sash frame. The insect’s shape is an almost perfect hemisphere, with black spots adorning its orange elytra (forewings adapted as wing-cases). On its pronotum (the hard plate covering its thorax), it sports an M-shape mark, typical of this species.

Aphid Eaters: Multi-Colored Asian Lady Beetles

Updated February 24, 2025

Every so often throughout the winter, I become aware of a lady beetle waking up from her diapause to see if it’s spring yet. She’s been sleeping with her friends in odd corners of the house, with a few holing up in the can lights in the kitchen. They fall on the floor. The dogs […]

Another insect on the screen on the south side of the house on a cool fall day. It looks like a honeybee (a drone honeybee at that), but is a Common Drone Fly. It has a rotund body with circling tan bands, hair all over, large compound eyes covering most its head. It’s a fly, with only one pair of membranous flight wings, unlike the bee’s two pairs.

On a late fall day, another type of insect clings to the screen. It reminds us of a bee with its fuzzy black and yellow stripes, but it has two translucent, membranous wings instead of four and bristles sticking out of its antennae. Also, unlike a bee, this critter has no waist and no stinger. […]

An insect with angular body, tiny head and two antennae sits head-down on a window screen in the autumn sunshine. Leaf footed bug has flattened, leaf-shaped expansions on its hind legs, which give the animal its name.

No Beauty Queen: Leaf-Footed Bug

Updated November 25, 2024

In the late fall, all manner of insects are planning to spend the winter on Owl Acres. They are congregating and searching for sheltered places to survive the snow and wind and the drop in temperatures. Asian lady beetles swarm out of the fields where they had been eating aphids. They line themselves up on […]

Alt text: Horror on the porch. A bright green caterpillar hangs from the defoliated stem of a tomato plant, which the animal has been feeding on. Its back bristles with more than 70, tiny white cocoons, each housing a wasp pupa. The tomato hornworm is still alive, but is doomed. It has been successfully hijacked as host for the little parasitic wasps and will not complete its own life cycle, to become a five-spotted hawk moth.

Hollowed Out for Halloween

We’ve heard a lot about viruses these past few years, with the corona virus front and center. We’ve all been scared at some level about getting COVID. We worried about how sick it would make us and whether we might spread it to someone else. So when I think of a virus, I think of […]

Updated October 14, 2024

On one of those glorious fall days recently, I took Dave and Clancy for a walk. As we strolled along the road, the breeze from the south ruffled my hair and extinguished the sound of the interstate a mile to the north. It carried the scent of ripening corn. Close by the crickets and katydids […]

Dozens of aphids, all head down, stud the stem of a Jerusalem Artichoke in the prairie garden. A lone black ant patrols the herd.

Raising cattle for milk and beef has been an important part of the activities on Owl Acres for over 150 years. Another kind of animal husbandry has been going on here for millions of years. We noticed it recently when we were inspecting a Jerusalem artichoke plant in our prairie garden. Ants were tending a […]
