Life in the Wind (July 2021)

As we all well know, if we want to preserve a wild hog's head, 
there's labor to be had unless we are wanting just the skull. 
And as you already may be doing, tying scrap bailing wire around the pig's head 
and hanging it in a cedar elm for a couple years will prove effective. 
(A hillside woods-full of such hanging heads 
would make for fun surprises when neighbor boys go a-rambling.)


Katydid eating what we think was a sweet Indian mallow flower at the top of the Hill (July 10)

The eternally enjoyable website bugguide.net tells us that katydids are "Probably mostly herbivorous. Some species reported to eat flowers" (https://bugguide.net/node/view/36998).  Yes.





The brown seeds of the milkweed plant. And the 
shiny silk-like "floss" attached to the seeds.
Growing at the top of the Hill (July 10).

Appears that there are over a hundred species of milkweed in America. Sometimes it's called "silkweed" for that beautiful "floss" that helps the seeds catch wind for more efficient dispersal. (Because it's waterproof and buoyant, the silk was used in WWII for stuffing inside lifejackets. 
Before that in the 1800's, it was used for soft stuffing inside mattresses.)

Milkweed bugs (Oncopeltus fasciatus). They love to eat
the milkweed seeds but won't kill the plant. (July 10)




Zexmenia. The book World Dictionary of Plant Names says this name is an anagram of the last name of Francisco Ximenez. Who, presumably, had little to do with sex mania.  Here's some of why Senior Ximenez might be remembered in Central America, where, as it turns out, our Zexmenia plant is native:

    "Francisco Ximénez (b. 28 November 1666; d. between 11 May 1729 and mid-1730), a Dominican priest who translated the Popol Vuh, the Maya-K'iche' story of creation.
    Born in Écija, Andalusia, Ximénez joined the Dominican order in 1688 and was sent to Guatemala to continue his religious studies. He was ordained in 1690. His facility for learning the Indian languages soon became evident, and he was assigned as parish priest in San Juan Sacatepéquez to learn the Kaqchikel language. Under the guidance of another friar who knew Kakchikel, he prepared a grammar in that language and went on to master the K'iche' and Tz'utujil languages.
    While serving in Chichicastenango from 1701 to 1703, Ximénez found a manuscript of the ancient book of the K'iche' people, the Popol Vuh. He translated into Spanish its story of creation and the history of the K'iche' nation. The Popol Vuh is now considered the national book of Guatemala." 
(https://www.encyclopedia.com/humanities/encyclopedias-almanacs-transcripts-and-maps/ximenez-francisco-1666-1730) 

"The Popol Vuh, meaning “Book of the Community,” narrates the Maya creation account, the tales of the Hero Twins, and the K’iche’ genealogies and land rights. In this story, the Creators, Heart of Sky and six other deities including the Feathered Serpent, wanted to create human beings with hearts and minds who could “keep the days.” But their first attempts failed. When these deities finally created humans out of yellow and white corn who could talk, they were satisfied. In another epic cycle of the story, the Death Lords of the Underworld summon the Hero Twins to play a momentous ball game where the Twins defeat their opponents. The Twins rose into the heavens, and became the Sun and the Moon. Through their actions, the Hero Twins prepared the way for the planting of corn, for human beings to live on Earth, and for the Fourth Creation of the Maya."

 Let's just stick with the yellow flowers.


Wedelia acapulcensis or Wedelia texana (Aster Family).
Zexmenia, Texas creeping-oxeye, etc. (July 16)



Mosses and lichen in full-hydration during an unusually wet season
(among the limestone boulders along the cliffside)

And so the word here is poikilohydry. As in the inability to maintain water content when the environment fails to provide it. So we'll see all manor of ferns, lichen, and especially mosses shrivel up into a desiccated piece of crispy brown during a drought--only to green up in minutes once rains pour over them. (Microscopic animals are also adept at poikilohydry, going dormant, and even catching winds and being transported miles high and miles wide across the earth.)


Unseen animals.

This sky, and the one below, don't help us to appreciate the recent haze caused by Saharan dust blowing in from the east. But it's not just sand that blows in. The "skeletal" remains of gabillions of diatoms are all mixed up in that dust, too. Maybe a third of the dust is comprised of the desiccated algal-like plankton that once swam within the now dried-up lake Megachad (bigger than all of our Great Lakes combined). 7000 years ago, with a different climate, north Africa was loaded with lakes. That was then. Now the skeletal remains, meters thick with these microscopic lives, get all caught up in the winds and float in great clouds to land in the Amazon, the Carribean, and the asthmatic lungs of some who live on the banks of this Creek.

So diatoms fly away:

The low density, high surface-area-to-volume ratio, and large aspect ratios of freshwater diatom particles suggest a mechanism by which they can be carried great distances aloft.” https://miami.pure.elsevier.com/en/publications/atmospheric-transport-of-north-african-dust-bearing-supermicron-f
Diatom-art of German artist and biologist Ernst Haeckel.
This is from his Kunstformen der Natur (Art Forms in Nature).

1904


And not just microalgae do fly. 

   “Many small animals, mainly arthropods (such as insects and spiders), are also carried upwards into the atmosphere by air currents and may be found floating several thousand feet up. Aphids, for example, are frequently found at high altitudes.

   "Ballooning, sometimes called kiting, is a process by which spiders, and some other small invertebrates, move through the air by releasing one or more gossamer threads to catch the wind, causing them to become airborne at the mercy of air currents. A spider (usually limited to individuals of a small species), or spiderling after hatching, will climb as high as it can, stand on raised legs with its abdomen pointed upwards ("tiptoeing"), and then release several silk threads from its spinnerets into the air. These automatically form a triangular shaped parachute which carries the spider away on updrafts of winds where even the slightest of breezes will disperse the arachnid. The flexibility of their silk draglines can aid the aerodynamics of their flight, causing the spiders to drift an unpredictable and sometimes long distance. Even atmospheric samples collected from balloons at five kilometres altitude and ships mid-ocean have reported spider landings. Mortality is high". https://en.wikipedia.org/wiki/Aeroplankton

Non sequitur...

For the first half of the month, we were still gathering
fenceline-blackberries for breakfast



Creek 2021 (satellite) vs 1953 (animals in an airplane took this photo)
Note the absence of pond, except for a small pool where the Spring lies in 1953.

Desaguaderos
Old maps tell us things. 
This turn of the eighteenth century one 
tells us nothing about where we are in central Texas, though. 
(Unless "desaguaderos" is meant to suggest something about those of us 
who live in the drain of Texas.)



Early Summer



          It’s easy to become depressed. 
          It’s also easy to become happy. 
          If we swim in water we become wet, and if we immerse ourselves in the right environment, we sometimes can become happy. This is old news for those who favor an “environmentalist” sociology and the same old foolishness for those who favor a “bootstrap” psychology. All I know is that when I am around friends, when I eat clean food from the garden, when I am lost in creative activity, or when I am silently looking deep into stream waters I forget how to be depressed. Afterwards I realize that I am happy.
            Though there’s no guarantee that a morning spent immersed in natural surroundings will cure whatever anxieties or depressions are killing us, I cannot recall a time when looking closely into the compound eyes of an insect or watching small fish hunt the shallow riffles did not result in a healthier and more grounded attitude afterwards.  Crawling on all fours in a grassy field or sitting still in dappled shade and watching for birds is a fairly reliable and inexpensive happy-pill with few adverse side effects.  And working a hoe or watering a plant at any time of day, alone or with a friend, is an activity for which we seem hardwired.
            Sadness and depression, like unhealthy weight gain, happen over time, and if one thinks about the long series of mistakes, wrong turns, or injustices that have built this unholy feeling, he or she might become even sadder with the loss of any quick fixes.  But as the Chinese proverb says, “The best time to plant a tree is twenty years ago.  The second best time is today.”  And that’s done in small, well-placed efforts.  Like making the next meal a plate of fresh colors or the next expenditure of calories a walk up a hillside with a friend. 
            We cannot all of us grow a garden big enough to feed us every meal, but we can begin by at least sneaking in a handful of bean seeds beside the house or sharing a space of soil with others and sowing carefully enough seed to produce a fair basket of vegetables and fruits.  A seed is not a guarantee when seen from the perspective of planting-day, but from the perspective of harvest-day, that seed is seen as an absolute necessity by an order of magnitude infinitely more sure than any other sort of promise.
            I envision sharing the Creek and its ancient loamy dirt up on the second cut.  Even if someone else cannot live in a small cabin beneath the boulders of Whitman’s Rough, and even if someone else cannot work the garden or tend the vines in an intentional community every day,  two or three others might be able to drive out here for a day of shared labor and shared meals at a board set in the shade of a tree planted before any of them were conceived.
          Until then, we settle for only the occasional explorations with only a few friends.  That's what we are sharing here below and elsewhere on this site.







Below is a short clip of what I'm guessing is the caterpillar of a five spotted hawk moth (Manduca quinquemaculata) . This isn't a positive identification, but it comes close. If it's not the same, it's close kin to the tomato hornworm that invades gardens and can strip a tomato plant of its leaves in quick order. One reason I remain somewhat skeptical of my identification here is that I recall that our specimen was feeding on the leaves of Gaura parviflora, and this is not in the Solanaceae family. And it's my understanding that the hawk moth's larvae feed on plants within Solanaceae (tomatoes, tobacco, peppers, eggplant, potatoes, etc.). See the video clip of the sphinx moth under blog entry "Early Spring" for a moth that closely resembles this caterpillar's eventual adult stage. Maybe.



Virginia Tiger Moth (Spilosoma virginica)?


The red phase of this Central Texas Leaf katydid often appears in periods of a population breakout such as what we are witnessing this summer. Some of the katydids we are seeing are truly red. Marvelous.





The hens must be getting used to their new surroundings quite well
because egg production has not slowed down since their move to the creek.





And from Harlin:
Invisible Scenery
I’m pretty sure that if the sepals shown in the close-up photographs were many inches across, they would be widely collected as strange objects and used to decorate all sorts of household items throughout the land. As it is, they are just barely visible even while squinting. The Shinner’s key says they are distinctive: “fruiting tepals varying from spiny-toothed to subentire” is one of the indications this is Rumex pulcher.

For me the invisible didn’t stop there. There are the three larger tepals with the reticulate surface and the yellowish ornaments, and there are three small linear ones as well. I had the whole assembly magnified and it took several tries to see all six. I guess it was all those spiny edges which camouflaged the three smaller ones. When the larger tepals are pulled apart the three sided seed falls out (one per flower).

. . . My will to identify is ebbing. How can there be so many damselfly niches in couple of hundred square feet of rock and water? The color blue isH not a sure fire characteristic; I think all of the following are sometimes brown depending on sex or some other accident. Not only does blue not distinguish among the damselflies, but blue butts don’t either. Many damselflies have the last few segment mostly blue.

Thank you, Harlin, for the photography lessons......

May Waters--May Lives











Harlin:


Perhaps one thinks to one’s self “it should be easy to find the story behind this creature of the wild”, and then one is reminded that pride comes before the fall. Yep, that’s what happened. I have a full color field guide to grasshoppers and all of the internet so I figure this dadgummed katydid will be no problem. But, after a long time I just don’t know what the story is. The book says that if the wings bow out and there are a couple of wrinkles across the pronotum then that is a sign you are looking at a true katydid (as opposed to the other kinds). The distribution map puts Paracyrtophyllus robustus in the center of Texas. However the back of the pronotum is supposed to be rounded.

Maybe not what my picture
[photo above] is of. The pictures on the internet are not reassuring either. Here is one in which at least the colors are in the ball park.

http://bugguide.net/node/view/425549/bgimage

Whatever it is, there are many of them and they are enjoying the walnut or pecan tree that is to the north of the central oak. One of the features of katydids is apparently that they are hard to see since they are at the tops of trees where we aren’t very often.

Here is how bugguide.net explains it:
Order Orthoptera (Grasshoppers, Crickets, Katydids)

     Suborder Ensifera (Long-horned Orthoptera)

          Infraorder Tettigoniidea (Katydids, Camel Crickets, and relatives)

               Family Tettigoniidae (Katydids)

Below is a picture of a small moth. It was on my shirt sleeve and I could see it had a pattern that looked promising. It waited until I finished my sandwich, went with me to get a camera, patiently endured several bad photographs, flitted down to the picnic table for a different view, and finally had this recognizable picture taken.

Really, really nice wings as far as I’m concerned.

The books says the larva of Petrophila bifascialis “scrapes diatoms and other algae from rocks of fast moving streams where it lives in a silken web.” (Peterson field guide-Eastern Moths). Maybe the name translates to two striped rock lover—what do you think?

Hedgehog or Lace Cactus (Echinocereus reichenbachii)
Trumpet Creeper (Campsis radicans)


The unifying theme below is the idea of the seed pictures being at least as good as the plant pictures.



Rattlesnake Weed (Daucus pussilus)

Other common names seem to be “southwestern carrot”, “southwestern wild carrot” and “American wild carrot”. There are small backward pointing barbs on the end of the spine and doing a little bit of searching turned up several terms used to name them: barbed bristles, uncinate bristles, and glochidiate prickles. I think “glochids’ are the small devils that get you when you brush up against the prickly pears. (Actually “devils” is not the correct term but rather a euphemism so as not to offend any government agents reading my electronic mail). I guess “glochidiate” means “glochids in reverse”.

In any case, these are seeds that are designed to catch onto fur in order to get dispersed.

.



Acalypha (Acalypha phleoides)

My pictures of the flowering parts of this plant just weren’t very satisfying. Then I noticed that I might be able to stick two of them together to at least give an idea of what the whole thing looks like. There are female flowers lower and male flowers higher. Some of the male flowers are sporting a spot of white pollen. The female flowers have three styles each of which splits into many ends.
Chenopodium with beetle

(Chenopodium or maybe berlandieri)

The name depends on knowing the difference between “mealy” and “glandular”. I’m thinking this is a case of “mealyness”. Also the seeds do look a little bit like they have a “honey combed” surface and the plant stinks which are other features of Chenopodium berlandieri. (There is a different name on the list I just sent you
[see previous post], but I’m going to change it.) This plant is close to the north east corner of your septic tank field. It is a little bushy and has kind of gray-green leaves. Get close and see if you don’t agree that “stink” is the right word.

The Flora of North America has a description of Chenopodium, and my going through the key leads to C. berlandieri. There are many varieties and they all say fruiting in the fall. Well, at least it doesn’t say only in the fall. The key to the varieties is a little more ambiguous, but Google books has the information below. I’d say the tidbit about the smell being like the air from an inner tube nails the identification.

Plants of Deep South Texas: A Field Guide to the Woody and Flowering Species
By Alfred Richardson, Ken King

Below are two photos from plants which we have been seeing for a while. The red seeds that are a little bit winged give confidence that there is a Plantago rhodosperma by the creek. The other picture is of Arabis petiolaris and it shows one of the seeds coming out of the long pods. Also, the older pods become translucent which I think can be photogenic.





One might think that one only needs one sample. One would be right if one had a perfect memory, but I’m not that one. For me there are (at least) two kinds of information overload when doing nature puzzles. The first is that it’s hard to remember whether I’ve seen one of whatever it is previously. The second is that I know I’ve seen one of that group before, but I don’t know enough about the group to know whether the one I’m looking at now is a different from the one I was looking at before. For instance, there are many kinds of winecups and I don’t know if the one today is the same as the ones I saw on the other side of the property last year.

The wild oats seemed like it might be new to the list but the grasses blur together even more readily than those with more colorful flowers. The distinguishing features of grasses are at the millimeter size level and I am not reminded of those traits by just wandering around in the fresh air. So especially for grasses my pattern is to go through the tour of interesting landmarks provided by the plant key and then forget. I think we talked about the possible positive side effect of this: one gets to repeat a discovery of the same thing for several times, but after the first time there is also a little let down that I’ve been here before and didn’t realize it. The outcome of this situation is that it’s often best to get the sample. Either it will be new or I’ll be doing remedial communing with nature.

In this case Avena fatua is new to the list.

One would think that oats would be edible, but the Shinners book says it has a habit of having bad fungus growing on it and says that hay containing sick oats can hurt the horses or cattle which eat it. There is a poison symbol by this plant. In one of the photos below you may be able to see a kind of smudge in the spikelet that is the dust from some sort of fungus.
