The demise of an ant on a snail

with 13 comments

As you heard and saw last time, on the Blackland Prairie in Pflugerville on April 30th I stopped to photograph some dodder (Cuscuta spp.). In one place a small snail had climbed up on a plant that the dodder was attacking. Snails often climb plants here, so that’s not unusual, but when I got close I noticed something I don’t remember ever seeing before: an ant had died on the snail, perhaps caught up and immobilized in the snail’s slime.

Dodder on the prairie

with 22 comments

On the Blackland Prairie in Pflugerville on April 30th I stopped in several places to photograph dodder (Cuscuta spp.), a parasitic plant that sucks the life out of other plants. Victims in the downward-looking photograph above include square-bud primroses (Calylophus berlandieri), firewheels (Gaillardia pulchella), and antelope-horns milkweed (Asclepias asperula). Here’s a much closer view from the side showing dodder attacking a square-bud primrose:

Parasites repel people, and that’s understandable, but dodder’s yellow-orange-angelhair-pasta-like tangles offer a visual complexity it’s hard for a nature photographer—at least this one—to pass up.

If you want to know more, come read an article of mine about dodder that the Native Plant Society of Texas just published.

Prairie parsley on the Blackland Prairie

with 11 comments

A couple of posts back you saw an Eastern black swallowtail caterpillar that I found on a prairie parsley plant (Polytaenia nuttallii) when I visited the Blackland Prairie west of Heatherwilde Blvd. in Pflugerville on April 30th. After I went back the next day and explored a different part of the parcel, I came across a great stand of prairie parsley flowering away, as shown above. How’s that for density? The mostly red flowers mixed in, by the way, are Gaillardia pulchella, known as firewheels and Indian blankets.

The closer and more downward-looking view below reveals that some of the prairie parsley plants had begun going to seed. The purple flower heads are Texas thistles (Cirsium texanum).

Black swallowtail caterpillar

with 35 comments

When I wandered out onto a piece of the Blackland Prairie on the west side of Heatherwilde Blvd. in Pflugerville on April 30th, I noticed that one of the prairie parsley plants (Polytaenia nuttallii) was host to the caterpillar of an Eastern black swallowtail butterfly (Papilio polyxenes). You can learn more about this species in a Wikipedia article.

Wind on the Blackland Prairie

with 20 comments

Yesterday morning I went back to the west side of Heatherwilde Blvd. in Pflugerville, back to a piece of the Blackland Prairie that I’d found in full flower the day before. With the wind gusting to perhaps 25 mph (40 km/hr), I took many pictures at a high shutter speed to stop the plants’ movements. The photograph in this post came into being at 1/1000 of a second.

The yellow flowers are square-bud primroses, Calylophus berlandieri. The clusters of much smaller yellow flowers atop tall plants are prairie parsley, Polytaenia nuttallii. The yellow-fringed red flower heads are Gaillardia pulchella, known as firewheels and Indian blankets. The blowing grass is purple three-awn, Aristida purpurea, which arcs over even without any wind and still suggests it’s being blown sideways.

The flowering goldenrod I photographed on the Blackland Prairie in Pflugerville on September 28th attracted many insects, including this American snout butterfly, Libytheana carinenta.

Why I’d gone back to the prairie

snow-on-the-prairie-fruiting-by-broomweed-colony-0951

On September 28th I went back to the new street in Manor called Wildhorse Ranch Trail to see how the snow-on-the-prairie was coming along on the Blackland Prairie since my last visit exactly three weeks earlier. I found that most of the Euphorbia bicolor plants had produced their fuzzy little tripartite green seed capsules, as you see here. In the background is part of the flowering mound of broomweed, Amphiachyris dracunculoides, that dazzled you last time (I hope you won’t mind if I put words in your mouth).
