2025 Caterpillar Season – Baileya Moth
Baileya Caterpillar
Baileya sp. fam. Nolidae
Host plant: Not recorded
Dates found: 30 August, 2025

Notes: There are four to six Baileya species found in Missouri. Although host plant preference may help to distinguish species, physical characteristics are of little help.


WGNSS Entomology Field Trips – September/October 2025
I’ve gotten to a point in a personal project that I can now spend some time posting more frequently here and processing some photos that have been backing up. Not that I have had a ton of success in getting significant photo opportunities the last several months.
The following are some photos of interesting insects that the WGNSS Entomology Group found on a couple trips to Missouri glades last year.
First up are a couple of moths found at a light trap we set up during a camp out at Caney Mountain Conservation Area in late September. The cool conditions were not conducive to attracting many moths, so the pickings were slim.
Next up is the fantastic Cicindelidia obsoleta vulturina (prairie tiger beetle). This species is primarily found in Texas, but there are scattered populations in Missouri, Arkansas, and Oklahoma.



Finally, from a trip to Hughes Mountain Natural Area, we found a good number of Trimerotropis saxatilis (lichen grasshopper) Fam. Acrididae. These masters of camouflage utilize open, rocky areas like Missouri’s glade habitats.


2025 Caterpillar Season – Plagodis Geometer
Plagodis Geometer Caterpillar
Plagodis sp. fam. Geometridae
Host plant: Not recorded
Dates found: 06 September, 2025
Locations found: Babler State Park, St. Louis County, MO
Notes: Plagodis larvae are well camouflaged to look like woody twigs on their host plants. Their body shape and coloration are not their only tools to use in their adaptive subterfuge. When disturbed, these twig mimics will become rigid instead of attempting to flea, often assuming this position while being handled.

Snail Kite!
This post is dedicated to my friend and mentor, Godfrey Bourne. Godfrey researched Snail Kites for his Ph.D. work while at the University of Michigan. I remember listening to some of his stories and seeing photographs of this impressive bird of prey. Around 25 years later they were still high on my wish list to find and photograph. Last week, I just happened to have a work trip down to Orlando, Florida. I made sure I had time for a personal day or two and the Snail Kite was the primary species I sought out over all the impressive birds that can be found in the state.

After watching some videos from a well known bird photographer on YouTube, I got the impression that this species might be difficult to find – that these birds are only found in wetlands away from developed areas that take knowledge and special equipment to reach. With my experience last week, I am beginning to think that this photographer’s motive was in selling his high-priced workshops.

Don’t get me wrong, with a current population estimate of approximately 2,000 individuals in Florida, these are not common birds; in fact, they are listed as endangered in the United States. This is primarily due to overdevelopment of wetland habitat in the sunshine state along with mismanagement of these habitats that has led to the decline of apple snails – the Snail Kite’s only food source. Thankfully, this species has a large range across the neotropics, from Mexico and the Caribbean to Southern Brazil. The species as a whole is currently not threatened with extinction.

In two close by areas, only a 30 minute drive from Orlando, I was easily able to find four Snail Kites and watched them for hours in a lake/marsh area that was heavily used by recreating people. Seeing as this is an endangered species, my intention was to give them plenty of room, but I was shocked as I watched people pass by them within just 10 feet or so without the birds seeming to care. On a couple of occasions, I sat down under a shade tree with 50-100 feet between me and the bird and was astounded when they flew closer and closer to me during their foraging. I have always said that any bird photograph taken in Florida should have an asterisk attached due to these birds being so accustomed to people. After just a couple of days experiencing this myself, I still feel this way!
This species numbers in Florida are highly affected by drought conditions and have varied wildly in recent decades. Changing climate patterns are not helping the Snail Kite restoration attempts and I fear for what the next decades may bring. Hopefully they will be as easy for me to find during my next visit to Florida. Thank you for reading this far and I’ll leave you with a few more photos.

Mating Harvestmen
During a WGNSS Entomology Group trip in September of last year, we were thrilled to come across a mating pair of Leiobunum vittatum (eastern harvestmen) at Caney Mountain Conservation Area. In some of the photos below, you can see the male handing off his prenuptial gift to the female. Prenuptial gifts are produced by the males and consist of a mix of essential amino acids. Mating behaviors in harvestmen are complex and vary wildly between taxa. Unfortunately, these guys were among thick scrub that made for difficult photography. I tried my best to capture some of this behavior.
2025 Caterpillar Season – Virginia Creeper Sphinx
Virginia Creeper Sphinx
Darapsa myron fam. Sphingidae (Hodges#7885)
Host plant: Found on grape species (Vitis sp.)
Dates found: 31 August, 2025
Locations found: Tyson Research Center, St. Louis County, MO
Notes:


2025 Caterpillar Season – Definite Tussock Moth
Definite Tussock Moth
Orgyia definita fam. Erebidae (Hodges#8314)
Host plant: Found on sycamore (Platanus occidentalis)
Dates found: 01 September, 2025
Locations found: Tyson Research Center, St. Louis County, MO
Notes: This species range seems to weirdly stop in extreme eastern Missouri based on official collection records as well as online databases like iNaturalist and BAMONA. I wonder if this species might be more abundant in the state than the data suggests, mainly by the numbers I have found during the past two years.


2025 Caterpillar Season – The Brother
The Brother
Raphia frater fam. Noctuidae (Hodges#9193)
Host plant: black willow (Salix nigra)
Dates found: 16 September, 2025
Locations found: Johnson’s Shut-ins State Park, Reynolds County, MO
Notes: This species ranges over most of the lower 48 United States and southern Canada. It is infrequently found in Missouri.
