1) Metaphorical Metamorphosis
October brought a welcome change to Tandy Hills Natural Area. It seems like Mother Nature's odometer passed a milestone. Day after day of Indian Summer weather provided perfect temps for hiking and discovering hidden treasures. Add a couple of nicely spaced rain showers and prairie metamorphosis is under way. There are signs of life where none were present just a few weeks ago. Flying insects have reappeared in swarms, perennial wildflowers have new growth, even the grasses have produced a touch of green. Overall, there's a very limited palette of color to be found after the blistering drought but, there are notable exceptions. The day after an October 'norther blew in, a steady succession of Monarch butterflies fluttered unwaveringly over the Autumn hills and a date with metamorphic destiny. Their orange-black wings contrasted sharply against the jet-blue prairie sky. Days later, crusty pods of Milkweed, their larval host plant, began spewing their ballerina-like seeds skyward, as if welcoming the Monarch's return. All of nature is submitting to transformation of one kind or another. Even us bipeds, far removed from the natural world, feel the tug of change coming on as Summer inevitably fades and we look ahead to Winter. Some of us grow more hairy or fat while some prepare for hibernation. According to doctors, the very composition of our blood changes in Fall and Spring, whether we know it or not. After the Great Drought of '11, a metamorphosis is just the ticket. Shed your chrysalis and migrate over to Tandy Hills. Your host plants are waiting. DY

2) Metamorphosis Moment
In the first week of October, I was lucky enough to witness a metamorphic stage of the Cloudless Sulphur butterfly (Phoebis sennae). You may recall from Prairie Notes #58 that, Two-leaf Senna is a larval host plant for this bright, voracious little creature. As lovely as the flighty, lemony-colored butterflies are, I found their caterpillar counterparts to be stunning works of art. I had hoped to document every stage of the metamorphosis but alas nature didn't cooperate. Soon after I photographed the larva you see below a heavy rainstorm moved in. The critter was gone the next day. A few days later I spotted a Sulphur butterfly in the vicinity. Go here to watch a time-lapse video of a, Phoebis sennae, pupating and emerging: http://www.youtube.com/watch?v=GTUgUEpqBrA&feature=dir
Phoebis sennae, in all its glory shares a name with its host plant. Note the tiny water droplets on the tiny hairs of the Cloudless Sulphur catterpillar. Note the web-like threads the larva has woven on the Senna leaves.
3) Field Report
-My intro above tells most of the story. Although most of the grass will be back next year, only few patches of Sideoats Grama and Little Bluestem have recovered enough to produce seed this year. Here's a partial list of wildflowers blooming at press time: Broom, Crow Poison (in very large numbers), False Gaura, Gayfeather, Giant Blue Sage, Heath Aster, Maximillian Sunflower, Old Plainsman, Skydrop Aster, Two-leaf Senna, Vervain, Wild Garlic. FYI: The weather is nearly perfect for kicking around at Tandy Hills and discovering these treasures. Golf-ball size heads of Wild Onion (or is it Garlic???) are a cheerful sight in October. False Gaura flowers atop their long, long legs. A few Gayfeather plants bloomed after October rains adding some much-needed color to Tandy Hills.
4) Wildflower of the Moment
The moment for this odd-looking plant has just passed, but during October, it flourished in a few odd locations at Tandy Hills. Beach Groundcherry (Physalis cinerascens) is in the Solanaceae or, Nightshade family whose members include potato, tomato, tobacco and many toxic plants. The fruit, encased in a lantern-like sack, is similar-looking to Tomatillo. It tends to grow in disturbed areas such as, near the street, so it is easily overlooked. Nonetheless, it was one of the few bright spots on the prairie in early October. Quarter-size blossoms of, Beach Groundcherry, basking in the morning light of Indian Summer. Lantern-like fruit of, Physalis cinerascens, are reminiscent of Tomatillo's.
5) Fossil Find
Debora Young found this exquisite fossilized shell at Tandy Hills recently. It reminded me that Tandy Hills has, is and will continue to undergo its own kind of metamorphosis. I think this example is from the Cretaceous period, a time when the Earth belonged to no one and to everyone. Check out this nifty website devoted to North Texas fossils: http://www.northtexasfossils.com/ Trigonia calvigera? aka: a Clam. A relic from a time when Tandy Hills was ocean-front property.
6) Fog on the Prairie
On the morning of October 24, a heavy fog crept over Tandy Hills allowing me to observe the magical ways that H20 clings to wildflowers.
"The fog comes on little cat feet. It sits looking over harbor and city on silent haunches and then moves on."
-Carl Sandburg, 1916 Giant Blue Sage flower petals look striking in any kind of weather. Note the tiny Cicada on the fog-drenched Two-leaf Senna flower. Fog adorns Two-leaf Senna leaves in distinctive patterns.
7) Prairie Plant Puzzler
Do you know me? My long prickly vines thread discreetly through the tall grass at Tandy Hills, year-round. But when my blooms are on the vine you'll think it's the 4th of July! Right now I'm getting ready for Spring so, all you'll see of me are my very touchy leaves. That's a BIG hint and the only one you you get. (Be the first to guess my name and win a beautiful, organic cotton Tandy Hills bandana that'll blow your mind.) Stumped by the September puzzler? Answer: Eryngo (Eryngium leavenworthii) Fog droplets on my little leaves give me the shivers. What's my name?
8) Kestrel Sighting
An American Kestrel Hawk was seen patrolling the sky over Tandy Hills in October. They seemed to be less leery of humans than Cooper's and Red-tailed Hawks, allowing me to get much closer. A lone American Kestrel is a new addition to the Tandy Hills fauna.
9) Prairie Proverb
"You said you wanted to put us on a reservation, to build us houses and make us medicine lodges. I do not want them. I was born upon the prairie, where the wind blew free and there was nothing to break the light of the sun... If the Texans had kept out of my country, there might have been peace. The Texans have taken away the places where the grass grew thickest and the timber was the best. Had we kept that, we might have done the things you ask. But it is too late. The whites have the country which we loved, and we only wish to wander on the prairie until we die."
