Native forbs peak in midsummer across glacial till remnants

, , , and are all leafing into their July bloom across the native forb community of the glacial till plains. Observed at multiple sites within fifty kilometers of the city center, these species are ecological remnants of the tallgrass prairie mosaic that once stretched continuously across this landscape, shaped by Pleistocene glaciation into some of the most fertile and botanically diverse terrain in eastern North America.

This July flowering window was once tended deliberately. The Miami and Potawatomi peoples managed these prairies with fire for centuries, maintaining the open structure that blazing star and lobelia depend on for dominance. Without regular disturbance, woody encroachment displaces them within years. In the fragments that survive here — cemetery prairies, restored roadsides, park edges — this midsummer bloom is among the most important of the year for the specialist native bees that evolved alongside these plants and have no functional substitute for them.

An Eared Grebe far from the salt lakes settles on Morse Reservoir

September 16, 2026

An has been sitting on the water at Morse Park, on the shore of Morse Reservoir in Noblesville, since at least the second week of September. Birders have reported a single bird there thirteen times, most recently on September 14. This is a western bird. Eared Grebes nest on prairie marshes and shallow alkaline lakes from the Dakotas west to the Sierra, and most of them never come this far east. In central Indiana the small grebe that usually shows up on the reservoirs in fall is the Horned Grebe, and by mid-September the two look alike enough that the differences matter. Both have shed their breeding colors; the Eared Grebe's black neck and gold ear tufts are gone by now. What is left is a dusky little diver with a peaked crown. The peak sits at the center of the head on an Eared Grebe and toward the back on a Horned Grebe. The Eared Grebe's forehead rises steeply, its neck is thinner, and its bill is finer, with the lower edge angled slightly upward so the whole bill looks tipped up. Its face is the best mark at a distance: on a Horned Grebe the white cheek and neck are clean and bright, with a straight border against the dark cap; on an Eared Grebe the gray bleeds down into the cheek and the neck stays gray rather than white. An Eared Grebe also rides with its rear end cocked up out of the water, which a Horned Grebe does not do. How this species spends its autumn is unlike almost any other bird. From late summer into November nearly the whole North American population, close to 99 percent of it, flies to two salt lakes, Mono Lake in California and Great Salt Lake in Utah, to feed on brine shrimp and alkali flies. There each bird more than doubles its weight, from around 260 grams to over 600, while its digestive organs swell and its chest muscles shrink by about half. The birds become flightless for three to four months while they fatten, then rebuild the flight muscles and leave for the Gulf of California and the Salton Sea. Because a version of this cycle repeats several times a year, the Eared Grebe spends roughly nine to ten months of each year unable to fly, longer than any other bird that still flies at all. The bird at Morse Park is not doing any of that. There are no brine shrimp in a freshwater reservoir, so it is diving with its feet for what the impoundment offers: small fish, insect larvae, and small crustaceans. It flew here and will have to fly on, so its chest muscles are intact. It is a bird that peeled away from the movement toward the salt lakes, or was never headed there, and settled on the largest open water it could find in a county of till-plain farmland and subdivisions. Morse Reservoir is a dammed stretch of Cicero Creek, and to a grebe that is what matters: deep enough to dive in, wide enough to be seen from and to leave from. Anyone checking from the park should look for a lone, low-floating bird well out from shore, smaller than a coot, diving often and staying down long. If it is still around, the face pattern and the tipped-up bill will settle the identification.

Monarchs laying eggs on milkweed at midsummer

June 25, 2026

The common milkweed along the edges of White River State Park is in full leaf now, broad and upright, the stems thick with a white sap that bleeds if you snap one. This is peak summer in central Indiana, the longest days of the year, and the milkweed is doing exactly what monarchs need it to do: growing fast, producing new leaves, staying green and full of the compounds that make it both toxic and essential. A female monarch finding a milkweed patch does not land randomly. She walks the leaves with her forelegs, which carry chemoreceptors sensitive enough to detect the plant's chemistry through contact. She is tasting the leaf before she commits. If the plant is right, she curves her abdomen and deposits a single egg on the underside of a leaf, pale green and ridged, smaller than a pencil eraser. Then she moves on, usually to a different plant, sometimes to a different patch entirely. A single female may lay several hundred eggs over her breeding season, but she spreads them deliberately. One egg per leaf, rarely more. This matters because a caterpillar that hatches has only so much leaf within reach before it needs to move, and if eggs are clustered, caterpillars compete. The eggs hatch in three to five days, depending on temperature. The caterpillar that emerges eats its own eggshell first, then begins on the leaf. It feeds for roughly two weeks, molting through five distinct stages, each one larger and more boldly striped in yellow, black, and white. The milkweed's sap contains cardiac glycosides, compounds that are toxic to most vertebrates. The caterpillar does not detoxify them; it sequesters them, storing them in its own tissues. By the time it pupates, it is chemically defended, and the adult butterfly that emerges carries that protection forward. A bird that eats a monarch and gets sick will avoid the pattern afterward. The warning coloration is not decorative; it is the advertisement of something real. Common milkweed is doing more than feeding monarchs right now. Its flowers, dense pink-purple clusters that bloom just before midsummer, draw a wide range of insects. The brown-belted bumble bee works milkweed flowers regularly, and the western honey bee, an invasive species introduced from Europe, is often present in the same patches. Milkweed flowers have an unusual structure: the pollen is packaged in small paired sacs called pollinia, and an insect visiting the flower can accidentally slip a leg into a groove and pull the whole structure free, carrying it to the next plant. The mechanism is passive on the plant's part, but it is precise enough that pollination depends on insects of a certain size and strength. Small insects sometimes get trapped by it.

Streams still running low weeks after the drought "ended"

August 10, 2026

Streamflow gauges across the Loamy High Lime Till Plains are still reading well below the recent seasonal average this week (August 4-10) - at Fall Creek at Millersville, the latest reading was 7.23 ft3/s against a 90-day average of 230 ft3/s - even though the county's drought was officially declared over back in spring 2026. That gap between the paperwork and the water itself is worth watching. A multi-month drought built through last fall and was technically cleared months ago, but soils and stream baseflow don't reset the moment a monitor lifts a designation; recharge lags behind rainfall, especially once the evapotranspiration demand of August heat sets in. That means the streams and the ground around them are heading into peak summer stress already carrying a deficit, with less water in reserve than a normal late-summer week would offer. For the native forb stands and specialist insects reported here in July, this matters less as a direct threat than as a thinner margin: a dry spell or hot stretch that a fully recovered system might absorb without strain now lands on ground that hasn't finished catching up. Against that backdrop of reduced baseflow, wastewater discharge quality carries more weight than it would in a wetter year, since there's less clean water available to dilute it. The BELMONT & SOUTHPORT ADVANCED WASTEWATER TREATMENT PLANTS have an open permit violation on record, though no parameter-level details on the discharge itself were available this session. A stressed, low-flow stream is generally a condition under which effluent problems have less capacity to be diluted, but we don't have data here confirming what, if anything, this facility is currently discharging or what effect it's having downstream - that's a gap worth watching rather than a conclusion to draw yet. None of this is catastrophic on its own, but it stacks: a slow hydrological recovery, a summer heat load, and a permitted discharger out of compliance are converging on the same stretch of the plains at the same time. Watching how the till plains' streams and their associated prairie remnants fare through the rest of August will say a good deal about how much resilience is actually left in the system versus how much is being assumed because a drought declaration expired.
