September 17, 2025—my first sighting.

Lycus fernandezi on Roemer’s Acacia.

Nicknames: “Fernando” &”Hang Glider.”

The first time I saw this creature was back on September, 17, 2025, late in the morning. It stood out as a bright pop of color on a verdant green, blooming Roemer’s Acacia – Senegalia roemeriana.

As I approached this boldly-colored, orange and black beetle to come in for a closer look, it lept off the native tree it was poised on and helicoptered itself up, up, and on out of my way—just like an action figure in a movie or cartoon. I was starstruck!

Its unique wing spread and flight pattern as it flew away from me that day left quite an impression on my mind and in my imagination. I wanted the chance to see it again. I wanted the chance to see that impressive liftoff again.

Consequently, I set out to try and record its “liftoff” for us to experience and enjoy.

Fast forward to May 20, 2026.

As a friend and I made our way about the endangered Tamaulipan thornscrub habitat looking for native bees on a walking survey, she saw something and called out for me to look.

I spun around and, yet again, that bright pop of color against the greens and greys stood out against the landscape.

Could it be? After all this time of looking, watching and waiting? Had “Hang Glider” returned?

“Hang Glider is back!”

“Hang Glider”

I am happy be able to present “Hang Glider” taking flight for your review and enjoyment:

Up, up, and away…

In December of 2020, I read an article by W. F. Strong in the Magic Valley EC Members’ magazine, TexasCoopPower, entitled “He Gave Us the Stars.”  This article told the story of a man—Mr. William Johnson McDonald—whose extraordinary vision was the impetus behind the University of Texas’ McDonald Observatory located on Mount Locke and Mount Fowlkes in the Davis Mountains of West Texas. 

After I read this article, I was enraptured, enthralled, and invigorated at the idea of visiting this spectacular place.  At that very moment, with stars in my eyes, I added visiting the McDonald Observatory to a most prominent position on my vision board.  Right next to it, I enthusiastically penciled in staying at the Indian Lodge in Davis Mountains State Park to my vision board, as well.  (Two bucket list items for me!)

Fast forward, a little more than six years later after reading W. F. Strong’s article, to January 2026.  My sister and I made our first trip to Hotel Limpia in Fort Davis, Texas, Davis Mountains State Park, the Indian Lodge at Davis Mountains State Park, and the McDonald Observatory on Mount Locke.  Our main objective on what we considered a “scouting trip,” was to attend a two-day astrophotography class at the McDonald Observatory and take in as much of the surrounding sights as possible. 

The Milky Way peaking through the Davis Mountains in the parking lot of Indian Lodge, Fort Davis, Texas.

Our first night at the Indian Lodge, skies were clear.  We staked out some vantage points in the parking lot and seized the opportunity to start snapping portraits of the gorgeous night sky deep in the heart of West Texas.  The next day—day 2 of our scouting trip—we were on track to begin our first day of astrophotography class in the Frank N. Bash Visitors Center at the McDonald Observatory.  

A winter storm was nipping at our heels…

Shortly upon our arrival, though, we found ourselves facing the high probability that our trip would be cut short due to an approaching winter storm.  Consequently, we kept moving at a pretty good clip to try and take in as many of the sights as we could before we had to decide whether to stay for the second to the last day of our trip (and day 2 of our astrophotography class) or leave a day and a half early and get home safely well ahead of the storm.

Despite our pioneering spirit, tenacity, strong will, and desire to stay, we opted to leave West Texas a day and a half early in order to, ultimately, give me enough time to get out of the San Antonio area before the winter storm set in so I could head back to the Rio Grande Valley (RGV). In retrospect, leaving the Davis Mountains a day early did afford me just enough time to get back in the RGV and winterize things out at El Mesteño Ranch and my home before the freezing temperatures set in. It was a mad dash for sure.  Whew!!!

As I reflect on this trip, I give my sister the majority of the credit for helping me with astrophotography.  With her expertise, guidance, and experience, I was able to get some great photos of the Milky Way in the parking lot at Indian Lodge and of the night skies over the McDonald Observatory.  Naturally, when I got back home in the RGV, I had to head out to El Mesteño Ranch on the South Texas Sand Sheet—just a few days after our full moon on February 1, 2026—to try and capture some of the incredible night skies deep in the heart of the South Texas Sand Sheet.

Thankfully, I was able to get a picture of “El Guapo,” a handsome, male Mesoxaea texana, sleeping in the curved, green leaves as a gentle Southeasterly breezed rocked him to sleep.  This is a sight I may never get to see again, and I do feel blessed to have had this opportunity to photograph it for us.

Male Protoxaea gloriosa nectaring on Waltheria indica on May 21, 2025! It’s been four long years since I last laid eyes on them!

by C. M. Rich, Texas Master Naturalist

Dear Fellow Nature Enthusiast,

As I was making the rounds on my little place out in the South Texas Sand Sheet on Saturday, May 17, 2025, scouting for bees, birds, butterflies, and blooms, I was ecstatic to see and record a male Mesoxaea texana (Mt) nectaring on Waltheria indica once again!  Just like clockwork, and according to the records I have been keeping in my phenology journal, it was time for Mt to return!   

The male Mt, which I have affectionately nicknamed “El Guapo” back in 20221” did not disappoint me.  However, what made El Guapo’s sighting even more remarkable is that it was heralded just moments before by its fellow subfamily Oxaeinae member, the Protoxaea gloriosa! 

The Protoxaea gloriosa, which I affectionately nicknamed “El Glorioso” back in 2021, was also nectaring on Waltheria indica! 

Alternate view of the male Protoxaea gloriosa nectaring on Waltheria indica.

As an aside, the last Protoxaea gloriosa that I recorded on my place was in the Spring of 2021. Remaining hopeful that “El Gloriosa” would one day return, I have been looking for them ever since.  It only took approximately four (4) years of waiting, and it was worth it!  Now, I have given myself a photo / video challenge:  Record as much of “El Glorioso” as possible. 

Protoxaea gloriosa caught in a Lynx spider’s deadly embrace circa May 2021.

My phenology records show a cyclical trend—maybe pattern or cycle might be better descriptions—on the amount of time I might expect to see the Mesoxaea texana and indicate that I will get to document the male a few weeks before the female Mesoxaea texana show up.  The overall trends on when the cycle starts and stops for this rare native bee, according to my phenology journal data entries, demonstrate that its arrival on the South Texas Sand Sheet has historically been from the months of May to June—even sometimes carrying over into the first week of July. 

Last year, the Mesoxaea texana showed up between approximately May 26, 2024, through July 2, 2024.  They were spotted on Salvia ballotiflora.  A special treat occurred last Fall, 2024, when the Mesoxaea texana reappeared for a second cycle above the ground on the South Texas Sand Sheet from approximately August 24, 2024, through October 26, 2024.  During their second cycle, they were spotted predominantly on Waltheria indica, but were also observed on Salvia ballotiflora, Eysenhardtia texana, and Funastrum cynanchoides.

Over the past four years, I have not been able to conduct the same amount of Citizen Science research for the Protoxaea gloriosa as I have for “El Guapo” because I have not laid eyes on it in four years.  My luck seems to be changing this year, however!  So now what?  What about “El Glorioso?” How long will we possibly get to see it on the South Texas Sand Sheet?   Will it be long enough to start collecting data? My hunch about “El Glorioso,” based on what I have learned, is that the patterns I have observed and documented for the Mesoxaea texana, its subfamily member, will also apply and hold true for it as well. I guess we will see.  Time (and data) will tell their tale. 

Male Mesoxaea texana nectaring on Waltheria indica.

I will be, once again, starting up my intermittent, random walking surveys of all nine monitored sights.  I will be looking, in earnest, for their nests this year; it is on my bucket list to be able to document them!  I will continue to record ground temperatures at the monitored sights, track rainfall, record what’s blooming, and generally keep my eye out for anything that seems remarkable and worthy of note during these two rare, native bees time above the ground in this cycle of their lives on the South Texas Sand Sheet.

Female: Shiny, black eyes ~~~ Male: Green, jewel-toned eyes

When I first encountered these two rare bees, they were in flight.

In fact, they flew right in front of me, and I almost ran into them.

I was confused as to what I was seeing.

Front view of the two, conjoined Mesoxaea texana in the act of copulation.

Initially, these two rare bees appeared to be a very long insect flying about three (3) feet above the ground.

It took me a few seconds to realize that this “really long insect” I had nearly bumped into was actual two Mesoxaea texana—conjoined—while in flight.

The Texas native plant these two Mesoxaea texana alighted on was a Salvia ballotiflora, also known as Shrubby Blue Sage.

By the way, this plant has been observed to be a favorite nectar and pollen source for them.

These two remained conjoined for quite some time.

Rough estimates, based on the metadata for all images and videos taken that day, suggest that they were in this state for approximately several minutes.

I have been stewarding this land for these bees since the Fall of 2020.

Their watch, care, and preservation has turned into one of the main “Passion Projects” of this chapter of my life.

Stay tuned. There is definitely more to come.

Thanks for your time!
