2025 City Nature Challenge Recap for Kansas City Metro

The City Nature Challenge is an annual event that I always look forward to, when I have no conflicting engagements. I tend to plan around it, in fact. This year’s edition was held from Friday, April 27, through Monday, April 30.

Some background is in order for those unfamiliar with this urban bioblitz. What began in 2016 as a friendly challenge between the California cities of San Francisco and Los Angeles has blossomed into a global project. The intent is to generate public interest in native urban flora and fauna, document as many species as possible during the event period, and build a database useful for assessing environmental trends both locally and globally.

Here in Kansas City, I am fortunate that the official map area includes counties a fair distance from the city. It is mostly rural in Leavenworth County, Kansas, where we live, but the town itself is at least suburban. Heidi and I usually travel to other areas, too, like Wyandotte County, Kansas, and Platte County, Missouri.

The weather this year was less than optimal, overcast virtually the entire time, cool temperatures in the low sixties (Fahrenheit), and occasional rain. Perhaps that is why public engagement was low. The stats are still coming in to iNaturalist, the web platform that hosts the observations for the event, but we had less than 300 people who contributed sightings. As a percentage of the human population, that is pretty dismal.

This unidentified web-spinning sawfly was one of my favorite finds in Havens Park, Leavenworth, Kansas.

Still, there is a current total of 3,744 observatios of 1,084 species (however iNaturalist defines that term, and it probably varies by taxon). Help in identifying observations has come from 349 individuals, from all over the globe. The border of Kansas and Missouri represents the eastern fringe of the Great Plains meeting the western edge of the eastern deciduous forest, so we have some diverse and interesting habitats.

Ultra-tiny ribbed cocoon-making moths, Bucculatrix sp, are abundant in our yard right now.

Personally, given the inclement weather, I looked at plants more heavily than I usually do. It helped that I now have an iPhone that takes photos which are comparable in quality to those produced by my Canon PowerShot SX70 camera. I think it performs better than the camera in some instances.

I can't believe I found this beautiful pair of Oak Stag Beetles, Platycerus quercus, under a chunk of dead branch in a front yard flower bed (male top, female below).

When Heidi and I went out together, we focused on birds. This was especially true at Wyandotte County Lake Park in Kansas, and at Weston Bend State Park in Missouri. Both parks are heavily forested, with a large reservoir at one, and small streams running through the other.

This Blue Corporal dragonfly was one of three species of Odonata I found during the CNC.

I don’t like that the City Nature Challenge brings out my competitive nature, but I feel compelled to demonstrate to other local citizens that insects and spiders are worth looking at. Consequently, I had the most observations for the Greater Kansas City Metro Area, and the second highest species tally. You can find the results for everyone at this link.

I did get in a blacklighting session in the front yard one night, but there was precious little flying in the cool temperatures.

This female ichneumon wasp, Xorides peniculus, was a new species for our home, at the front yard blacklight sheet.

It is a good thing that the nature challenge was not a week later. I went back to Havens Park here in Leavenworth yesterday, May 5, to find that a new gravel road had been laid, right through a small, ephemeral wetland, and over glade habitat at the top of the park. I am devastated and angry. Rumor has it that it will eventually be another paved trail for cyclists, dog walkers, and others. I am all for accessibility, when it does not compromise ecosystems. I don’t know that I will go back to the park now, but there is nothing similar within walking distance of our home (I don’t ride a bike, nor drive any longer, and we only have one car anyway). Pretty much everything else here is lawns.

One thing that appears sorely lacking for the City Nature Challenge is widespread publicity. There is a wonderful team of individuals at the Los Angeles County Museum of Natural History that organizes the event each year, but they can only do so much. They have to register cities, for example, which is a demanding chore all by itself. It is up to the individual metropolitan areas to do their own marketing.

Did you participate this year? Have you done so in years past? Please feel free to share your experiences in the comments. Oh, and check out my "non-bug" finds over on my Sense of Misplaced blog.

Grand Finale

Versute Sharpshooter (leafhopper), Graphocephala versuta

Every bugwatcher knows it’s coming in the late fall, and both delights in it, and mourns for the lost spring and summer, quickly fading from memory. That encore of insect abundance, from heavy, arthritic grasshoppers lumbering up wooden fences, to sun-seeking lady beetles, eager to find snug crevices to pack themselves into for the approaching winter.

Differential Grasshopper, Melanoplus differentialis, male.

Multicolored Asian Lady Beetles, Harmonia axyridis, nestle in bark furrows on a tree.

This year, here in Leavenworth, Kansas, the Indigenous Summer has been long, hot, and hopelessly dry. It seems to matter little to most of the insects, but birds stopped visiting our feeders. We saw dozens of gulls passing over for a couple of days, though, bright white against an azure sky, the wind speeding them along.

Juvenile Tuftlegged Orbweaver, Mangora placida

The air is thick with the exuberance of the minute, now that the larger butterflies are scarce, no longer competing for our attention. Dreamcatcher spider orbs snag the micro-confetti of aphids, leafhoppers, and gnats that are on the wing, or that get torn from their perches by the stiff, incessant wind.

Cloudless Sulphur, Phoebis sennae, female.

Falling leaves jerk my eyes in their direction, on the off chance that they are butterflies after all, like Eastern Comma or Question Mark, or the less common Goatweed Leafwings. Leaves that rocket from the ground skyward are grasshoppers sporting autumn yellow, orange, or black hind wings. The largest ones, with clear wings, that land in trees, are bird grasshoppers.

American Bird Grasshopper, Schistocerca americana.

Political campaign signs in our front yard are sometimes briefly occupied by insects or spiders. The spiders try to balloon off, or seek shelter in the little tunnels of the corrugated plastic. I like to think that they are all signaling their approval, but they are actually endorsing the more natural state of our property, our decision to not use chemical treatments of any kind, and otherwise steward the place through benign neglect.

Microleafhopper, Erythroneura calycula

Microleafhopper, Hymetta anthisma

Microleafhopper, Erythridula sp.

Microleafhopper, Balclutha sp.

Microleafhopper, Erythroneura elegans

Leafhopper, Pediopsoides distinctus

Walking the fence line in our back yard, I stir a myriad of tiny leafhoppers that alight briefly on the weathered, algae-stained boards. Despite their size, they are riotously colorful, with streaks and bands across their slender wings. Fireworks come in both bright and muted colors that echo the changing foliage.

A male Fork-tailed Bush Katydid, Scudderia furcata.

Earlier in the season, katydids and lacewings were vivid green. Now, they are dull brown, maybe reddish, with bursts of purple or pink. Little orange skipper butterflies pop as I stroll by the tiny lavender asters that grow low enough to dodge the mower blade, along the very edge of the curb by the busy four-lane. Yellows in the form of Cloudless Sulphurs, on a partly cloudy day, flitting from one cryptic flower to another in someone’s front yard.

A little worn, a Fiery Skipper sips nectar from an aster.

Flowers, too, bloom again. The goldenrod, and taller white asters reboot themselves for one more round of Can I Get a Pollinator?. They do, in flies and bees mostly. Wild Carrot never gave up to begin with, still looking fresh as a daisy, courting potential pollinators. They succeed, in the form of two metallic flies. The flies depart when a lone ant appears to steal nectar.

A flower fly, Helophilus fasciatus, and a Spotted Cucumber Beetle, Diabrotica undecimpunctata, enjoy goldenrod nectar.

Another October surprise….no, wait, today is November the second already….is an immature Carolina Mantis, sitting stock still among our backyard goldenrod. It is probably one molt away from adulthood, but I can’t decide if it is male or female. I wonder if there are any larger insects left to feed it, get it over the hump, or if it will die young, perishing as the teenage equivalent of its kind.

Immature Carolina Mantis, Stagmomantis carolina

There has finally been rain lately, including today, so perhaps there will be yet another burst of activity in its wake. There will still be ground beetles crossing the sidewalks, and grasshoppers basking on the pavement on warm days, to be sure. Fall Cankerworm has yet to even take the stage, but they don’t always, not every year, and I might not see them if the timing isn’t right.

Leaf-footed bug, Leptoglossus oppositus.

There is no metaphor here. This is just how nature works. It varies, it adapts, takes chances, weighing risks at a molecular level. Emerge now, or snooze another calendar year. We are slower to act, built to react instead of evolving to be proactive, and to accept whatever weather befalls us. The warm, sunny days seem to encourage our lazy nature, while nature bustles around us, unnoticed by most.

Aphid, Drepanaphis sp.
