A red theme
Wanderers through countryside with lots of prickly pears (Opuntia engelmannii var. lindheimeri) know that the cactus often attracts certain bugs. This is one of those, Narnia femorata, on a tuna, or fruit of the prickly pear cactus, in the Zilker Nature Preserve seven years ago today. The bug is a nymph in one of its early instars, which are the developmental stages that the larva of an insect passes through. Click below if you’d like a closer look at the bug as it appeared in a different frame.
Although Texas in the summer of 2011 was suffering one of its worst droughts in decades, when I recently looked back at my archive for August 12th of that year I saw that I went photographing in four locations that day and ended up with hundreds of pictures, like this one along Scenic Drive of ripe snailseed fruit (Cocculus carolinus):
I also found from looking at my archive that I went out taking pictures on 19 of the 31 days in that torrid August of 2011. You could say that I lived up to the motto of the USPS (United States Photographic Service): “Neither heat nor drought nor sun nor sweat stays these intrepid image gatherers from the due documentation of their appointed rounds.”

Katydid nymph on yucca flower
For the second post in a row, here’s a view from the Wild Basin Wilderness Preserve in Austin. The picture, which dates back to June 20, 2013, shows what I think is the nymph of a katydid, but if anyone knows otherwise, please speak up. The petal is definitely that of a yucca, probably Yucca rupicola. If you’d like an overview of how that species looks when it’s flowering, you can skip back to another post from 2013.

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

To bee or not to bee…
When is a bee not a bee? When it’s a fly masquerading as a bee and presumably gaining protection against predators that would fear the sting of a real bee. Thanks to Bill Dean, via BugGuide.net, for identifying this syrphid fly as a male Copestylum tamaulipanum. Today’s picture, which is from August 30 along US 183 in Cedar Park, also gives you a pleasant glance back at the flowers of Euphorbia marginata, called snow-on-the-mountain because of its white-margined bracts. For a zoomed-in look at the syrphid fly, click the excerpt below.

Paper wasps
When I was out on August 30th at a property along US 183 in Cedar Park photographing sumpweed and snow-on-the-mountain, I also found some paper wasps busy working on their nest. Notice the egg in one cell.

Olive hairstreak butterfly
During the same September 12th outing along the upper reaches of Bull Creek that brought you the previous picture of prairie agalinis I noticed that some frostweed plants (Verbesina virginica) had begun flowering. My focus in this picture, however, was on the Callophrys gryneus butterfly that was busy on many of those frostweed flowers. The generally docile little butterflies in this species are known as olive hairstreaks or juniper hairstreaks due to the green on their wings.

Harmostes bug
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.
UPDATE: Out of the blue, on August 29, 2021, a contributor to bugguide.net identified another of my pictures showing this bug as Harmostes reflexulus.

Another little creature on a flower
Not far in space or time from where I photographed the crab spider on a Texas thistle at the Purgatory Creek Natural Area in San Marcos on April 27th, I saw Acmaeodera beetles on flowers of the skeleton-plants (Lygodesmia texana) that were out in goodly numbers (both the beetles and the skeleton-plants).

Prairie promiscuity
The adjective promiscuous was originally applied (and still is) to different things that appear or are brought together in no particular order. That’s a good description of plants, or as Dolly Parton put it: “Wildflowers don’t care where they grow.” Here from April 22 on the Blackland Prairie in northeast Austin you see a mix of Engelmann daisies (Engelmannia peristenia), bluebonnets (Lupinus texensis), prairie bishop’s weed (Bifora americana), and a few pink evening primroses (Oenothera speciosa).
While prairie bishop’s weed flowers are tiny, at most a quarter of an inch across (6mm), I found plenty of insects attending to them, including a shiny blow fly (family Calliphoridae)
and a paper wasp.
UPDATE on December 5, 2017. John S. Ascher at bugguide.net has identified the blow fly as being in the genus Lucilia.

Speaking of antelope-horns milkweed
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.
