Moth Week 2026 by Phone

I am so far behind in uploading camera photos to my computer and external hard drives that I literally “phoned it in” for National Moth Week, July 18-26. The photos in this post were taken with my iPhone 14. I promise that eventually I will have camera photos added to most of my observations posted on iNaturalist.

Our set-up at Atchison State Fishing Lake.

Officially, according to the current status on iNat for the Moth Week project in Kansas, I finished with a little over 90 species of moths in 234 observations. That was better than I expected. June is typically a more productive month for moth diversity here in northeast Kansas, USA. I am also not very proficient in identifying moths. I must thank the very knowledgeable and generous experts on iNaturalist for helping me out.

I began the week by putting out our blacklight in the front yard, near the giant Pin Oak tree that is probably responsible for feeding most of our insect diversity, both literally and figuratively. The weather the entire week was mostly hot, and vastly more humid than we usually experience here, so that was in our favor.

Two days later, on July 20, I switched to the back yard. We now have an outlet on the exterior of our detached garage, so I also plugged in a bright white light. We usually use a lightweight Jackery generator to run both the blacklight and a terribly dim LED white floodlight. The brighter light with the traditional bulb drains the generator in less than a couple of hours, compared to the LED. I welcome suggestions for a brighter white light that will run longer through the Jackery.

Heidi spotted this Curved-ribbon moth, Dinumma deponens on the door to the garage. This species is native to Asia.

It is surprising how different the results can be between our two yards. The backyard includes overhanging branches of a Silver Maple in the neighbor’s yard, plus a strip of mostly native herbaceous plants like White Snakeroot, goldenrod, Coreopsis, and coneflower, some of which Heidi planted, some of which is volunteering.

Maple Looper moth.

We also have volunteer Eastern Redbud, Eastern Black Walnut, hackberry, and young Pin Oaks planted by the resident squirrels. Our backyard “lawn” features sedges, plantain, LOTS of violets (the ornamental variety), clover, wood sorrel, and other non-native species.

Walnut Catoptilia moth.

Heidi decided we should try blacklighting out of town, at the Atchison State Fishing Lake in Atchison County, Kansas, so on July 21, we gave it a try. As expected, we were initially inundated with midges from the nearby lake. Caddisflies and aquatic beetles also showed up in large numbers. I think I will wear a mask next time we are anywhere near water, to avoid inhaling the smaller insects.

Heidi found this freshly-emerged Honey Locust Moth on the ground, then put it on a tree trunk where the insect fully inflated its wings.

While we were waiting for things to simmer down at the lights, we looked around the forest edges, and managed to find a few moths that way, too, along with the odd beetle, spider, or other nocturnal creature.

We did not get back home until nearly two o’clock the next morning, but it was well worth the trip, and we will probably try again in the future. There was only one tent in the campground, and only two other vehicles came along. No one bothered us, though it helped that we were there on a weekday and not a weekend.

Hagen's Sphinx really does have this lovely mossy green tinge to it.

The night of July 24, I decided to be lazy and merely turn on the front porch light. Again, it is surprising what will come to the porch light versus the blacklight. Then again, at the porch light there are usually fewer numbers of insects, and I can concentrate on individual specimens.

A very shiny micro moth, Homosetia argentinotella, at the front porch light.

This is where I often find unique “micro” moths. Indeed, I added at least one new one to our home list of fauna and flora. I encourage everyone who participates in National Moth Week, or who routinely blacklights for insects, to pay special attention to micros. You could easily document something new to your county, state, or even the country.

Saturday evening, July 25, after a wonderful dinner at a local Italian restaurant, I walked through downtown Leavenworth and discovered several moths that were still present on storefronts, having been attracted to lights the night before.

This Maple Zale moth is not so well camouflaged on a windowsill in downtown Leavenworth.

I was secretly hoping to find a Black Witch in one of the recessed alcoves, but no luck. There have been records of that giant subtropical moth in the Kansas City area, but not yet this year.

From downtown, I walked up to my in-laws’ home and set up the blacklight in their back yard, something we hadn’t done in years. It was a near total bust. We were overwhelmed by caddisflies, literally thousands of them.

Spotted Phosphila Moth.

Ironically, away from the light I found a nice specimen of the Spotted Phosphila Moth, Phosphila miselioides. That was the highlight of the night, and we packed it in early.

An unidentified plume moth by our front porch during the day.

We ended the week on July 26 by setting up the blacklight in the front yard again, and shining the bright white light onto a sheet of foamcore in the back yard (we need another sheet). Naturally, some of the nicer moths I was only able to get photos of just after midnight. I may cheat a little and backdate a camera photo or two for moths that I know I saw prior to the closing bell. That’s allowed, right?

Yellow-winged Oak Leafroller moth at front yard blacklight.

I swear I saw this Painted Lichen Moth flying behind the sheet before midnight. Honest!

I hope you had success in your own Moth Week adventures, or that you will consider participating in future years. It is truly wonderful, fascinating, and sometimes challenging experience. It is even better with a small party of other excited people.

Remembering Moth Week 2025

Yes, I am terribly behind in making public my sightings of insects, arachnids, and other wildlife this year. I finally have my observations for National Moth Week 2025 loaded onto iNaturalist, but I will share some of them here in this post.

Zebra Conchylodes Moth, Eddyville, Kentucky.

Heidi was generous enough to secure us tickets to the Coldplay concert in Nashville, Tennessee, USA, so we spent almost the entirety of the week in that area of the country. We began in the Land Between the Lakes National Recreation Area. When we arrived, the weather was rainy and not at all conducive to looking for insects, but it was also the day before the start of National Moth Week.

This Pink-shaded Fern Moth was the first of its kind I'd ever seen.

We stayed at a small rental house near Eddyville, Kentucky, surrounded by deciduous forest. The first night, we simply left the front porch light on, and looked at the few insects that flew in, using the awning over the porch as convenient cover from the showers.

This Lost Owlet moth was also new to me.

The subsequent two nights were better. We put out our blacklight the second night, under the carport by a large metal garage building. The building had its own, motion-activated light, which helped draw more bugs to our sheet. The landscape was still quite wet, however.

Tulip-tree Beauty, a large geometer moth, was common at our lights....

....but harder to see on a tree trunk!

We debated whether to turn on the blacklight for our third and final night in Eddyville, but I decided against it. We did turn on a light over the back porch, though, and that attracted a good number of insects, including moths.

A Posturing Arta moth, posturing.

As we headed south, we entered Tennessee, and stopped at the lovely Cedar Pond Picnic Area. The sun had broken through permanently by now, so there was more insect activity. Around the pond were a couple of overlooks, and at one of those we startled a butterfly off a pile of scat from some mammal’s recent visit. On closer inspection, we noticed there was also a Nessus Sphinx Moth taking advantage of the fresh dung.

While we were in Nashville, we stayed at a hotel that did not permit us to do any blacklighting. Plus, there was the concert itself. If you have never been to a stadium concert for your favorite band, I recommend the experience. Highly exhilarating, and worth the expense.

Deep Yellow Euchlaena Moth, Giant City State Park, Illinois.

From Nashville we headed west to southern Illinois, an area rich in both biodiversity, and protected natural areas in which to enjoy it. There are wildlife refuges, state parks, and other places that have grassroots support from local friends groups, resulting in excellent maintenance and outstanding sources of firsthand knowledge.

Rosy Maple Moth.

We decided to visit Crab Orchard National Wildlife Refuge on the way to our destination of Giant City State Park. The visitor center was being remodeled, and it was about to close for the day, but we met a couple who volunteer there. They were friendly, and very helpful. Exploring the exterior of the building, I found a beautiful Rosy Maple Moth, still hanging out by a light it had been drawn to the previous night.

Caterpillars, like this one of a tussock moth, count, too, during National Moth Week. Lower Cache River, Illinois.

Jennifer Randolph, the naturalist and nature center manager at Giant City State Park had invited me to give a presentation on moths for her volunteers and anyone else interested, so we stayed at a cabin in the park for three nights.

The "working" part of our vacation, presenting on moths at Giant City State Park.

The first two nights we set up a blacklight on our cabin porch, and were rewarded with a spectacular variety and quantity of insects. The cabins are basically duplexes (front to back) offering comfortable accommodations for guests, and situated far enough apart that you are not disturbing your neighbors with quiet nighttime activities.

The Bad-wing is actually a real beauty.

On our last night, we set up our lights a fair distance away at a picnic shelter elsewhere in the park. There was a pole light by the shelter that complemented our dim white light and portable blacklight. We did not see many species different from what we had at our cabin, but there were some notable exceptions.

A large and lovely Azalea Sphinx.

On our drive back home, we stopped for a rest, rather randomly, at a Casey’s store in New Florence, Missouri. When I glanced up as we pulled into our parking spot, I could hardly believe my eyes. I blurted out an excited “Oooh, oooh!,” and pointed, wide-eyed, at the enormous female Imperial Moth perched on the wall beneath a light.

Moth Week could have ended there and I would have been happy, but we got home to Leavenworth, Kansas in time to set up our blacklight in the front yard for the final night, July 27. A few more species were added, and then it was over.

Unidentified dagger moth, genus Acronicta, Leavenworth, Kansas.

All of my observations can be seen at the hyperlink in the first paragraph of this blog post. Meanwhile, Heidi’s observations can be found here. We almost always see different species, even in the same place. Plus, her photos are usually better.

Linden Prominent moth was a new visitor to our Leavenworth, Kansas yard.

While there is an official National Moth Week, almost any time of the year can be its own moth week. There are still moths flying here in Leavenworth, at least until the first hard freeze. Turn on your porch light and see what lives in your own neighborhood.

Basswood Leafroller Moth, Leavenworth, Kansas.

NOTE: In the current, highly-charged political atmosphere, I strongly suggest navigating friends group websites for recreation areas, national parks, wildlife refuges, and other properties operated by the federal government, to avoid being subjected to biased and irrelevant content. Thank you.

National Moth Week 2024 Recap from Kansas City

We are in the Greater Kansas City Metro area, anyway, here in Leavenworth, Kansas. National Moth Week ran from July 20-28 this year, which was helpful because the weather was unstable and somewhat volatile, and we were traveling during the end of that time span. Our results were mixed, but they did include some new species for our property.

Chickweed Geometer Moth, Haematopis grataria, is a pretty dependable species for National Moth Week.

This part of the United States has received more rain this year than in the previous three that we have experienced. Oddly, this seems to have driven insect diversity and abundance down. Our plants are doing well. I had no idea that violets could grow that tall and that dense, for example. The goldenrod may be taller than I am by the time it blooms.

Green Cloverworm Moth, Hypena scabra, is common here most of the summer.

Black-bordered Lemon Moth, Marimatha nigrofimbria, has been a "regular" in our yard this year.

I walked our yard in the daytime on the afternoon of July 21, and flushed the above three moth species from our “lawn.”

Clemens' Grass Tubeworm Moth, Acrolophus popeanella.

That night I switched on the light for our covered side porch, which is only about five feet from the neighbor’s house, but only managed to attract a couple of grass tubeworm moths. Returning to the front entrance, I discovered what I believe to be an adult Variegated Cutworm lodged on the inside of the screen door.

Variegated Cutworm Moth, Peridroma saucia, I think.

Ironically, an unidentified tortricid moth appeared on the side porch screen door during the day on July 25.

On July 26 I hiked over to Havens Park, one of the few forested places in town, in hopes of flushing some underwing moths, as I have had fair luck in the past. Lo and behold, I did get one, an Epione Underwing, Catocala epione, that stuck around just long enough for me to get a couple of images. Breaking through countless spider webs strung across the trail was worth it after all.

Epione Underwing, Catocala epione.

I set up our entolight blacklight twice, once in the back yard on the night of July 23, and again in the front yard on July 26. The difference in the species between the two locations is rather surprising. Frankly, given that the federal prison, lit up like Las Vegas every night, is less than two blocks away, I am mystified as to how we attract anything.

Maple Looper Moth, Parallelia bistriaris.

The back yard yielded a few moths, mostly small and common species, but also delivered a couple of lovely, larger moths. When blacklighting, it helps to remember to look on foliage, tree trunks, fence posts, and other surfaces just beyond the reach of the illumination of your lights. Many moth species are “too shy” to come directly to the sheet.

Banded tussock moth, Halysidota sp., found in the shadows just beyond the reach of the light.

The front yard, like the back yard, had few moths at the light until about eleven PM. Naturally, every time I decided I should turn out the light for the night, something new would show up. I think I eventually went to bed around one AM. Thankfully, the neighbors tolerate our “hobby.”

Spotted Peppergrass Moth, Eustixia pupula.

Among the novel finds in the front yard was one of the crocus geometer moths in the genus Xanthotype. They cannot be identified to species from photos, so we will settle for genus.

Crocus geometer moth, Xanthotype sp.

Another interesting moth was a Yellow-collared Slug Moth, Apoda y-inversum. Their helmet-shaped caterpillars apparently feed only on the leaves of hickory trees.

All of my moth observations for the week can be found here on iNaturalist.

Packard's Wave, Cyclophora packardi, and a pygmy leafmining moth, Stigmella sp., immediately below it.

Next year I will try and schedule public events, as we did last year on Fort Leavenworth, for both a variety of habitat, and as a way to introduce others to the magic of moths. I hope all of you were able to enjoy this year’s edition of National Moth Week wherever it found you.

Zeller's Macalla, Macalla zelleri, a type of pyralid moth. Wish we had more, as their caterpillars feed on Poison Ivy.

It's National Moth Week Already?!

Yes, National Moth Week is once again upon us! This year it happens starting yesterday, July 23, and ends Sunday, July 31. NMW is an annual citizen science event that anyone can participate in. You might start by visiting the National Moth Week website for information about the history of the project, and how to contribute your observations.

Suzuki's Promalactis Moth, Promalactis suzukiella

Despite a breezy to gusty night last night, we hung a blacklight, with a white sheet backdrop, from our front porch in Leavenworth, Kansas, USA. Our neighborhood is more or less suburban, with modest yards around each home. It has been hot and humid, but with a prolonged dry spell, so I was not expecting much.

Yellow-striped Armyworm moth, Spodoptera ornithogalli, I think.

Still, we had many moths fly to our ultraviolet beacon. Many were small enough to be overlooked, or easily mistaken for leafhoppers, small caddisflies, or other insects. A few could be dismissed as bits of plant debris, so convincing is their camouflage, even on a white canvas.

Brown-shaded Gray, Iridoposis defectaria

Here is a small selection of some of the moths that appeared. I do not even know the identities of a few of them myself. Moths are that diverse, with little known about them unless they are of economic importance.

Skiff Moth, Prolimacodes badia

Walnut Caloptilia, Caloptilia blandella

Kermes Scale Moth, Euclemensia bassettella

Tubeworm moth, Acrolophus sp.

Small Baileya, Baileya australis

Stripe-backed Moth, Arogalea cristifasciella

Orange-headed Epicallima, Callima argenticinctella

The Wedgling, Galgula partita

Unidentified crambid moth

What is on your sheet, or at your porch light? Share them with the world.
