Spiranthesovalis var. erostellata can be very difficult to find. Usually growing in groups of ones and twos, it is a small plant that prefers shadier locations that get dappled sunlight. I want to thank John Oliver for all his assistance getting me on this and a number of other Spiranthes species this year.
This species of ladies’-tresses is known for its graceful and diminutive flowers. Casey and I found only a couple of plants, each with flowers rather less developed than hoped for. I’m not sure if we were a day or two early, or if this might be all to expect from this population. We found these plants alongside trails at Babler State Park in mid-September.
Casey and I found three separate populations of Corallorhiza odontorhiza in early to mid September this year, each population consisting of just a few bunches of plants. Most plants of this species found in Missouri are cleistogamous, containing flowers that never open and thus forcing the plant to self-pollinate. This might account for the rather dull colors and patterns on flowers of this species when compared to its vernal-blooming relative, C. wisteriana. Of the three locations, we found only one bunch of plants, located in St. Louis County, that contained open (chasmogamous) flowers and these were slightly more showy than I expected them to be.
Like C. wisteriana, this species is myco-heterotrophic, parasitizing mycorrhizal fungi to obtain carbon and other necessary nutrients. Consequently, this species never produces leaves. Both Corallorhiza species are found scattered throughout Missouri and can be found in a variety of habitats, but seem to prefer open woodlands on xeric to mesic soils.
Tipulariadiscolor, or the ‘cranefly orchid,’ was first collected in Missouri in 1988 and new discoveries across the Midwest in recent decades suggest it is actively expanding its range. Similar to the puttyroot orchid (Aplectrum hyemale), this orchid blooms in the summer without the presence of any leaves. Leaves emerge in autumn and are usually completely withered by May. Both the common and genus names come from the apparent resemblance of the open flowers to that of crane flies in the genus Tipula. Moths in the family Noctuidae are the primary pollinators and use their proboscises to collect nectar from the long nectar spurs of the flowers.
This is the only species in the genus to be found in the Americas. Casey and I found these plants in Stoddard County on August 1st of this year.
The habitat this featured orchid was found was quite interesting – a wet, fen-like area with many pea-gravel rivulets to walk down. All this was set under a thick overstory that allowed little light on the cloudy day Casey and I visited. Often forced to hunch as we searched for other plants, lighting for photography was challenging, but we got what we came for.
As you can see below, this is a dainty and sweet orchid that has a large primary leaf and a secondary, bract-like leaf.
After looking for a few years, I finally found a patch of black trumpets this year in Jefferson County, MO. They are reported to be one of the finest wild mushrooms and I agree – they (I picked and ate the ones pictured here) are definitely in my top three!
A few weeks ago Ev, Yvonne, Dave and I traveled south to try and find the first state record of the Brown Booby that was on the Current River just outside of Doniphan. Unfortunately, we were a day late and missed the bird. However, through the patient and educated eyes of Yvonne, we found several insects that made the trip worthwhile.
One of these that I was able to get some photos of was this striking great blue skimmer (Libellula vibrans). This is one of the largest of the skimmers and while not necessarily rare, it isn’t one you’ll come across very often in the St. Louis area.
We made a stop in Carter County before heading home to look for orchids. The orchids were a no-show, but Yvonne found her target species of the day – this gemmed satyr (Cyllopsis gemma) that we all had nice looks and photo opportunities with.
Although we missed out on our prized Booby, I’d say the Booby Prizes were well worth our time.
Early April, 2020, Casey and I head to the southwest corner of the state looking for multiple subjects. Our primary target of this trip was to check for caterpillars of a rare subspecies of the Baltimore Checkerspot (Euphydryas phaeton ozarkae). This subspecies occurs primarily in the Arkansas Ozarks, but can be found in extreme southern Missouri.
The main distinction that separates this purported subspecies is habitat and host plant preference. The primary habitat for E. phaeton phaeton is marshy wetlands, while E. phaeton ozarkeaprefers oak woodlands. The primary host plant for E. phaeton phaeton are the turtleheads (Chelone sp.) while E. phaeton ozarkea primarily uses false foxglove (Aureolaria grandiflora). These animals will overwinter as caterpillars and then will often find new host plant species the following year – as shown in these photographs, they are using lousewort (Pedicularis canadensis). They will then pupate in May to June of their second year.
Browsing the literature, there seems to be some who question the legitimacy of the subspecific status of of E. phaeton ozarkae. Is this simply a case of an opportunistic generalist finding new ways to make a living in varying habitats, or is there a concrete genetic distinction between these two? From what I’ve been able to tell, there does not seem to be a consensus. If you are aware of any newer literature that might shed light here, please let me know.
Just a few that I’ve processed that I wanted to share from this past spring.
Did you know…? Trilliums are a favored spring food by white-tailed deer. An overabundance of deer, as is found across most of the eastern United States forests, can have detrimental impacts to trillium populations. In some regions these plants and many other plant species are extirpated from certain forests except within deer exclusion fences.
One of the first wildflowers that really caught my attention. Miami mist can often be found in large colonies. Unless you stop to take a close look, it may not be obvious what you are missing.
I thought that celandine poppies were pretty common after visiting the large beds at Shaw Nature Reserve’s wildflower garden. I have now come to understand that they are generally pretty hard to find in Missouri forests. The name celandine comes from the Greek word for ‘swallow’, referring to the plant’s early blooming with the first arrival of the birds in spring.
Thought I was getting racy? These photos were taken at Weldon Springs CA this past spring when Dave, Miguel and I were hoping to score some photos of newly arriving birds. The birding was slow this day, if I remember correctly, but here is a fantastic example of why it is always worth while to get out as early as possible.
While standing on a low-water crossing the guys and I noticed a mass coming upstream towards us. It didn’t take long to discover that a beaver was on its way and would have to get by us to reach its destination farther upstream. We all shot away with our long lenses until this guy got closer than our minimum focal distances. It hesitated a bit and hurried back downstream as Miguel moved to get in a different position, but eventually climbed up the crossing and moved to the other side. He was so close to us during its crossing that Dave could have potentially petted him if he had wanted to.
This Stinkor was found in a nearby field later that same morning. The eyesight of both species is pretty awful. If you come across these guys, there is no need to be concerned. Simply move slowly and as silently as possible and you will likely have plenty of time to observe them without being noticed. I have had several close encounters with skunks and have never felt threatened with being sprayed.
The NEOWISE Comet, whose actual name is C/2020 F3, was a pleasant surprise for the astronomical community who await such events as a newly discovered comet. First discovered in late March, the comet grew steadily brighter, eventually becoming the brightest comet to be seen in the northern hemisphere since Comet Hale-Bopp in 1997. According to the experts, this comet had an orbital period of about 4,400 years prior to making its latest trip through the inner solar system. It will now be another 6,700 years before beings on earth will be able to see it again.
I have long had a very strong interest in astronomy and astrophotography and the current pandemic has allowed me to do quite a bit of studying on both topics. Hopefully soon I can get the practice in this area that I desperately need. Although it has some issues, I was relatively pleased at capturing the closeup of the comet pictured above.
Although I had a star-tracking mount that would have been perfect for this situation, I had not yet used it so I did not make this the first time. This image was “untracked” using a full-frame camera and a 200 mm lens. It is comprised of 20 “light” images (the actual photos of the comet) taken at 3.2 seconds per exposure. The aperture was f/2.8 and the ISO/gain was 6400. I combined these images with 10 “dark” frames for noise reduction purposes.
The processing here could be better and I might give it another try sometime. But, both tails of the comet are visible and I think the background stars came out alright as well.
After awhile the comet began to dive towards the horizon with the remnant glow from twilight. I happened to show up at Lee’s Bluff on the same night as accomplished Missouri nightscape photographer, Dan Zarlenga, and so we both turned our tripods around to the south and found this lovely scene. Here, the Milky Way has recently risen above a nice foreground of trees. Again, I wish I would have been a bit more prepared with a plan, but I guess this isn’t too bad.
