Tonight I’m finishing off the neighborhood deer photos from 2020. This buck pictured in the first two photos was a bit odd. Not just because of the aberrant antlers, but he also did not mind my close approach or my following him as he browsed.

A few more white-taileds from August. Have a look at the next three images. I’m hoping someone with some knowledge in the genetics of these guys might have some idea what is going on with the buck on the right. With his rack and size, he obviously has the genes, but he looks so different from what I think we would agree is a more typical buck next to him. In addition to the shapes of their heads and faces, their coats are vastly different as well. Thanks for sending any thoughts you might have about what these difference might be caused by.

2020 was a decent year for me in finding and photographing white-tailed deer. It started in the summer a I walked the high-voltage line cuts that run through our neighborhood. These turf fields, the wood lots and scrub fields that run along this area and our yards are home to a good size population of these deer. As I get more into landscaping our yard with native plants, I’m sure I’ll develop issues with these guys, but they are a lot of fun to watch and photograph.
Typically, summer bucks in velvet are not easy to see in the daytime. They typically stick to a small area, eat the abundant greenery and try not to damage their sensitive new headwear. Suburban bucks are different. In fact, I had much easier times finding bucks this summer in the neighborhood than I did during the rut season when they are typically easier to find and get close to.
That’s all for this set. Stay tuned and check back later to see more from the neighborhood this summer as well as images I took during the rut.

As it seems I say every year, I did not find the time to go out looking for insects as much as I had hoped for in 2020. Here are a few of my favorites from this past season. As always, please correct any inaccurate species identifications if you are in the know. I try my best, but can always be wrong. Thanks.
Thanks for the visit and wishing you a great 2021 filled with more insects!

Myrmecochory is a term that comes from Greek, created from “myrmeco” – of or pertaining to ants, and “chory” – plant dispersal. It is one of approximately seven plant “dispersal syndromes” classified by ecologists, is found in approximately 5% of the angiosperms and occurs in numerous ecosystems around the world.
Mutualism is thought to be the basis for this dispersal syndrome. Although this is not necessarily crystal clear, the ants are attracted to the eliasome – the fleshy structure attached to the seed that is a rich source of lipids, amino acids and other nutrients. The ants typically will move the diaspore (eliasome + seed) back to their nests. Dispersal distances vary, but are generally not great – most often 2 meters or less. However, for small forbs this distance is often adequate for moving these propagules outside the range of competition of the parent plant.
Distance dispersal is not the only selective advantage that plants gain from this mutualistic relationship. When the ants have moved the seeds to their nests, they remove the eliasome to feed their young and typically dispose of the seeds in their midden heaps or eject them from the nest. Seeds that are moved to midden heaps or other such locations benefit in multiple ways. First, they are placed in microenvironments that are conducive for germination and early growth. They are protected from heat of fire that could destroy the seeds and benefit from not being accessible to birds and other seed predators. This is referred to as ‘directed dispersal.’ Some studies have shown that the removal of the eliasome may promote germination, similar to the process of seed being removed from their fleshy fruit as it is passed through the gut of a vertebrate.
Their is typically no specialization of particular ants dispersing a particular plant species, with almost any ant species being ready to take advantage of a free meal. The possible exception being that larger diaspores must be dispersed by larger ant species.
My hope was to photograph myrmecochory across a variety of species this year. I was fortunate to find success with Sanguinaria canadensis but had no luck in my attempts with Dicentra cucullaria (dutchman’s breeches). I tried hard for trillium species as well but discovered the plants I was waiting for mature fruits for weeks were being harvested most likely by SNR staff. I will be trying for these again in the future and hope to photograph prairie species as well.
The fruits of Stylophorum diphyllum (celandine poppy), I discovered, had a much smaller window of ripening. I had to check at least every two days or I would miss the opportunity of a large fruit full of diaspores.
See below for my attempts at filming myrmecochory. This was definitely challenging. I had troubles predicting the ants’ behavior, especially while under the bright, continuous lighting needed for high-magnification photography such as this. Something else to try and improve upon next year.
I’d like to thank James Trager for his assistance with ant species identification.

This year I was fortunate to be introduced to two new-for-me shut-ins in the southern region of the St. Francois Mountains. Both of these locations are currently on private land and with assistance from a couple of friends, it was quite a thrill to be able to visit and photograph these stunning geologic features.
What surprised me most about both of these locations was that they were not covered in Beveridge’s “Geologic Wonders and Curiosities of Missouri”. I am not sure if this was because he did not know of them or because he chose not to feature them for some reason. I sure hope it was the later.
My recent delves into geology and astronomy have really been eye-opening, tying together everything else I know of natural history into place. There is so much more for me to learn, with Geology I know almost nothing, but it has been such an aid for me in remembering that most of what everyone worries over is so insignificant compared to the real that is right under our noses.
This is all I have to share from these two locations for now. I am looking forward to visiting again with hopefully more water flow and at different season. Thanks for visiting.

I finished 2020 having found all but one species of Spiranthes orchid expected to be found in Missouri. Many thanks to John Oliver for giving me a bit of education and help in making correct identifications; however, any errors found here are my own and no one else should be blamed. I also want to thank John and Casey Galvin for giving me the clues as to where each species could be found. Identifying these was not as difficult as I originally expected, minus the exception pictured above.
Spiranthes cernua belongs to a species complex that is still being worked out. In addition, I have read that there may be up to 20 or more “races” within this particular species. Not that all of these races are found in Missouri, but generally, this species blooms with leaves. I had a hard time coming to the correct ID because the plants I had found had no leaves at bloom. It took me some time to find out that there is a race in Missouri that does indeed bloom without leaves being present. I will stop here as I cannot speak in more educated terms about this plant other than to say I that I found it stunning.
Found across much of northern and southwestern Missouri on limestone glades and other calcareous substrates, Spiranthes magnicamporum, or the Great Plains ladies tresses was only just recently separated from S. cernua. It is distinguished from S. cernua not only by a few morphological floral characteristics, but also by its fragrance. S. cernua is either fragrance free, or with only a hint of olfactory cues, while S. magnicamporum typically exudes a lot of fragrance. On just the right day one may be able to find it by nose before finding it by sight. I found it to have strong vanilla and coumarin hints.
The flowers of the next Spiranthes, little ladies tresses (Spiranthes tuberosa) were described perfectly by Homoya as “jewelaceous”. Here he was referring to the jewel-like look that a magnified view of the flowers have. Many orchid flowers have this look, with each of the “jewels” being composed of individual cells. This is one of the daintiest of orchids found in the state. In Missouri, they are found in dry, sandstone habitats away from competition. Although quite small, when in bloom they should be easy to find as they stand virtually alone in brutal xeric habitat.
I typically don’t have very much luck finding caterpillars of the giant silk moths from the Saturnidae family. This past season was a little more successful. I found three polyphemus moth (Antheraea polyphemus) caterpillars and Sarah found the above luna moth caterpillar during our birthday hunting trip in mid-September. Larvae of these two species look very similar, but there are a few easy characteristics than can be used to distinguish between the two.
