Bug nymph on four-nerve daisy

with 36 comments

In contrast to the willful four-nerve daisy flower head (Tetraneuris linearifolia) you saw last time, the flatness of this one that I found on the same April 1st outing had me aiming straight down at it.

You’ll remember that each “petal” of a daisy is actually an independent flower known as a ray flower. The rays (14 in this case) ray-diate out from the flower head’s center, which is made up of many smaller individual flowers of a different type, known as disk flowers. It’s common in daisies for the disk flowers to form overlapping spirals, some of which go out from the center in a clockwise sense, and others in a counter-clockwise sense. If you count the number of disk-flower spirals in each direction, you typically get consecutive Fibonacci numbers. There’s a confirmation of that in the following enlargements of this four-nerve daisy’s disk. Go ahead, count the number of spirals going each way and you’ll see:

In the unlikely event that anyone ever asks you if daisies know how to count, you can confidently and Fibonaccily say yes.

Looking and looking back

with 16 comments

When I knelt to photograph a yellow bitterweed flower head (Helenium amarum var. amarum) in Cedar Park on May 6th and looked through my camera’s viewfinder I found a bug staring straight back at me.

If you’re interested in photography as a craft, I used point 11 in About My Techniques to create this image.

Harmostes bug

Harmostes Bug on Horesmint Flowers by Firewheel 7371

From June 8th, 2015—a year ago today—along Old Spicewood Springs Road, here’s a mostly side view of a bug in the genus Harmostes, which crowned some horsemint flowers, Monarda citriodora. The imaginary sunset in the background, whose warm colors contrasted so pleasingly with the green of the bug and parts of the horsemint that it dominated, was a firewheel, Gaillardia pulchella.

Note: I’m away from home and will be for a while. Please understand if I’m late replying to your comments.

Speaking of antelope-horns milkweed

Milkweed Bug on Antelope Horns Milkweed Leaf 2134

Speaking of antelope-horns milkweed (Asclepias asperula), as I did last time when I showed a snail on one, let me add that I also noticed a typical quota of milkweed bugs (Oncopeltus fasciatus) on the antelope-horns plants that I stopped to examine on the prairie in northeast Austin on April 22.

For a closer look at the milkweed bug, the better to see it staring back at you, click the excerpt below.

Pale Green Bug on Ageratina havanensis 7329

How about this bug in the genus Harmostes that I found on an Ageratina havanensis bush that was flowering way out of season on June 8th along Old Spicewood Springs Road? (Thanks to the folks at bugguide.net for quickly identifying the genus.)

The red and the black

Click for greater clarity.

No, not the novel by Stendhal, which I confess I haven’t read, but this red and black bug, which is perhaps in the genus Lopidea or Oncerometopus, on a Mexican hat, which is definitely Ratibida columnifera. Like yesterday’s photograph of a silverpuff seed head, I took this one on Harrogate Dr. in northwest Austin on August 13.
