R.I.P. LRGV?

Barring a miracle, construction of another segment of the U.S.-Mexico border wall will begin in the Lower Rio Grande River Valley (LRGV) in mid-February. Many people are under the mistaken notion that the President has not achieved his funding goal for the border barrier. While this is true, in part, funding for the segment running through Hidalgo and Starr Counties in Texas was approved in the omnibus bill passed in March, 2018. The habitat destruction this will cause is incalculable. It will also take place during the migratory bird breeding season. Wait, there is more.

To pave the way for the border wall in the legal sense, executive orders rescinded protections afforded by: The National Environmental Policy Act, the Endangered Species Act, The Federal Water Pollution Control Act (Clean Water Act), The Migratory Bird Treaty Act, The Archeological Resources Protection Act, The Solid Waste Disposal Act, The Historic Sites, Buildings, and Antiquities Act, The National Wildlife Refuge System Administration Act, and The Native American Graves Protection and Repatriation Act, among several other distinguished pieces of legislation (nearly thirty in total) that make this country truly great.

Make no mistake, the construction of a border wall, or even a fence, would doom the economies and ecologies of the Lower Rio Grande Valley LRGV) in south Texas. Public and private lands alike would take the brunt of a closed border, effectively impoverishing every aspect of life in the region. I speak from having visited the area on three separate occasions. The map below shows what would be lost, effectively ceded to Mexico, south of that orange and yellow line. "What?!" you ask, "That is nowhere near the actual border!" Exactly. The true border is the Rio Grande River itself, but by law there can be no barrier constructed within the floodplain of the river. The wall will therefore be placed on existing levees on the U.S. side, far from the riverbank.

Among our favorite places in Texas is Bentsen-Rio Grande Valley State Park, a world-famous destination for tourists wishing to see birds, butterflies, dragonflies, and other watchable wildlife found nowhere else in the United States. The planned route for the border wall would exclude visitors from half of the current acreage, if the park even remained open to the public at all. This is what the average American does not seem to understand: The rights of American citizens will be denied as a result of this massive undertaking.

The National Butterfly Center, where new U.S. records for Mexican species are documented almost annually, will likewise be heavily compromised, and that is private property. Why Libertarians and others who hold private property in sacred esteem are not up in arms over this is beyond me. There was a lawsuit filed, but because all afforded protections were removed in the rescinded federal laws, the lawsuit was dismissed.

Were it not for persistent and vocal protests, the Santa Ana National Wildlife Refuge would already be bisected by the wall. For now it has received a temporary stay of execution (of wall construction). The refuge is a gem, with a variety of habitats and mind-blowing biodiversity from "bugs" to birds.

A border wall would have a devastating impact on wildlife, for even though birds could fly over the barrier, the habitat would be so fragmented by the structure and accompanying 150-foot "enforcement zone" that migrant wildlife would no longer have refuge in their travels; and resident wildlife would likewise be displaced. Meanwhile, have we learned nothing from the insidious networks of tunnels beneath our existing border barriers? Do we truly believe for an instant that "coyotes" will be deterred from their businesses of human trafficking and gun and drug running?

Opposition to a border wall can take many forms, and you are encouraged to pursue one or more of them:

  • Engage in in-person protests at various border locations.
  • Call, write, and e-mail your U.S. Representatives and Senators to express your outrage in polite but assertive language. Demand an immediate moratorium on further border barrier construction.
  • Bombard the White House with calls, e-mails, and letters.
  • Donate to the National Butterfly Center and other conservation organizations, and humanitarian non-profits that are fighting the border wall.
  • Continue visiting the border and infusing the local economies with your tourist dollars. Ask locals how best you can help them fight the wall. Tell locals who are in denial or who are misinformed that this is an urgent and critical situation that will adversely affect them.

Our current U.S. President is hell-bent on erecting a highly visible monument to his own fear of immigrants and refugees instead of enacting foreign and domestic policies that would defuse volatile relations with Mexico and Central America instead of igniting more fires. He insists on punishing law-abiding citizens in the U.S. instead of crafting more stringent laws against human trafficking, and expanding the currently overworked agencies charged with handling the deluge of legitimate refugees seeking asylum.

Foreign policy should address corrupt governments that lead to mass exodus, but we need the cooperation of our allies, the UN, and other international bodies that the President has turned his back on. We may even need more official ports of entry along the border so that the few currently in play are not overwhelmed, and adjacent lands between those posts can be patrolled more easily.

We have by no means exhausted all our options with regard to immigration reform, but we will be taking a step backward by building a wall. We are literally robbing ourselves of precious and unique landscapes and ecosystems. Yes, Mr. President, a wall would be something concrete, literally if not figuratively, but what you personally gain from visibility you will lose by several orders of magnitude in credibility, both at home and abroad.

Fun With Austin Butterfly Forum

It was my honor to be invited to give a presentation and participate in "bug walks" with the Austin Butterfly Forum in Texas from April 22-24. Special thanks to Mike Quinn for extending the invitation, and to Dan and Linda Hardy for hosting Heidi and myself at their lovely home. We were fortunate to have agreeable weather there, though we left Colorado Springs with snow on the ground and returned to more flurries.

The turnout for all of the scheduled events was impressive considering that we were looking for insects rather than birds. The Sunday outing included people who drove from as far as Houston to spend about half a day with us. The Monday evening meeting, held at the Zilker Botanical Garden, was likewise well attended, and select ABF members furnished refreshments. You do not go hungry or without entertainment in Austin, at least if the ABF has anything to say about it. Let us start from the beginning, though.

Heidi and I arrived early afternoon on April 21, and Mike Quinn whisked us off for some vittles at Threadgill's, an Austin landmark packed with music memorabilia of rock and country genres. The weather was humid with intermittent drizzle, but we went to visit the Zilker Botanical Garden anyway. This lush park is full of all manner of native and exotic plants, landscaped in a manner that was bird- and bug-friendly. We found several caterpillars, true bugs, beetles, and butterflies despite the overcast skies.

We then went next door to the Austin Nature and Science Center and the Zilker Nature Preserve behind it. We quickly spotted a Diamondback Watersnake digesting a recent meal on an island in a small pond. One of the naturalists who was leaving for the day described a vireo nest in the preserve, and sure enough we were able to locate that, too, but not before finding a tarantula in her silk-lined lair. The vireo nest looked like it was holding a recently-hatched Brown-headed Cowbird, much to our disappointment.

By now we were killing time until the famous bat flight from beneath the Congress Avenue bridge in downtown Austin. Walking along the river we found a few more birds, including a Yellow-crowned Night-heron stalking the shady shore. After a quick bite at Freebirds World Burrito, we were ready to witness the spectacle of over 500,000 Brazilian Free-tailed Bats exiting their haunts from beneath the bridge. We were not disappointed.

About twenty minutes after sunset, they started streaming from the southern end of the bridge, followed eventually by others farther north. Please go see it for yourself, from both the bridge and from a boat or kayak. There are even commercial boat cruises specifically for this purpose.

Something has our attention at Brackenridge Field Laboratory

Sunday morning we convened with other members of Austin Butterfly Forum at Brackenridge Field Laboratory. Several buildings, greenhouses, and uncovered water tanks occupy the property, but there are also acres of undeveloped property that we prowled for insects. The most startling and exciting organism we encountered was a coral snake, right on a paved path.

After a pizza lunch delivery, we toured the insect collection, a sizeable holding of preserved specimens. They had just received a donation of butterfly and moth specimens that have yet to be integrated into the larger collection. Lastly, we looked in on a greenhouse containing live tropical longwing butterflies (Heliconius and related genera). It was much like the commercial butterfly houses one pays to visit, but with a scientific purpose to analyze genetic lineages in these insects. Some specimens were easily recognizable as a particular species, but others were obvious hybrids.

After lunch, Heidi and I retired to our host's home, where I explored a greenbelt ravine behind their property. The "hill country" is crossed by streams that erode the limestone rock that gives the landscape its topography. Live oak is the dominant tree, but there is a good diversity of vegetation. It is a distinctly arid habitat, but southerly enough in latitude to get animals like anole lizards and, unfortunately, fire ants.

Monday morning found us strolling along the Barton Creek Greenbelt Trail, west from the Barton Springs Municipal Pool, a popular swimming hole. There were plenty of butterflies and other insects to be seen, including the ever-present Southern Dogface, Pipevine Swallowtail, and Gulf Fritillary. We did manage a splendid White-striped Longtail skipper, which was only the second specimen I'd ever seen.

We were eventually able to access the nearly dry creekbed, where Heidi spied a local rarity: a Filigree Skimmer dragonfly.

There were a handful of other dragonflies, and many damselflies, too. Heidi also pointed out a couple of Six-spotted Fishing Spiders waiting in ambush at the edge of one of the puddles now making up Barton Creek.

The riparian trees are full of birds, and we got to see a White-eyed Vireo collecting spider silk to line its nest. Northern Cardinal, Northern Mockingbird, and Great-tailed Grackles were among the most obvious birds here and within Austin as a whole, at least during our brief visit.

Between lunch and dinner I did a bit of exploring in Dan and Linda Hardy's backyard, which is mostly wild, native vegetation and the occasional deliberately installed plant, like "Antelope Horns," a type of milkweed. As luck would have it, it was in partial bloom, and crowded with three Gray Hairstreak butterflies and one gorgeous green Juniper Hairstreak.

A Springtime Darner dragonfly eluded my attempts to get its picture, and the large, red paper wasps were almost equally good at hiding as they hunted for other insects. I was, however, able to repay our host's hospitality, at least in part, by recording the first Banded Hairstreak butterfly in his yard. I hope he has since been able to find one for himself.

My after dinner presentation "Beyond Birds: the Joys of Bugwatching" was apparently well received, and afterwards I signed copies of the Kaufman Field Guide to Insects of North America for several appreciative folks.

Wait, there's more....

Enjoying Lady Bird Johnson Wildflower Center

Tuesday morning found us at the Lady Bird Johnson Wildflower Center, an epic tribute to Texas flora on 284 acres. There is an ongoing invertebrate survey that has, to date, recorded 93 species of butterflies alone at the site. All wildlife is welcome, and our particular visit coincided with the presence of fledgling Great Horned Owls right at the entrance to the whole park.

After lunch, before our departing flight, Mike took us to Hornsby Bend, a wastewater treatment and research facility that includes large retention ponds frequented by birds and other wildlife. We saw many shorebirds there, as well as Painted Bunting and, finally, a pair of Scissor-tailed Flycatchers as we were exiting. It was a fine conclusion to an exciting, memory-filled trip. Thanks again to everyone who made it possible.

New! "How to Make an Insect Collection"

You may have noticed the new tab at the top of this page. Click on it and you will be taken to a comprehensive and highly organized text and graphic document on how to make an insect collection. This may prove useful to teachers, students, naturalists, and citizen scientists wishing to collect insects in a fashion that will enhance their historical and scientific value as preserved specimens. I recognize collecting is not for everyone. I know some people who only collect specimens they find already dead. Whatever your personal inclination, please understand that without specimen collections, our collective scientific understanding of the world would be non-existent. Thank you.

Sponsors and Advertisers Welcome

As always, I welcome sponsors and advertisers to support this blog. BioQuip and Tender Corporation are currently my only sponsors. I did apply recently for a grant, but am not assuming anything about the outcome. Long-term loyalty is what I am most looking for. Please contact me if your institution or business is compatible with the educational goals of this blog, and you would like advertising space.

Thank you, Donors!

I would like to publicly thank the many individuals who have contributed financially or in-kind to the endurance of this online publication. Your support is immeasurable and invaluable. I am considering adding another tab (page) to recognize donors by name. Please let me know if you think this is a good idea, an invasion of privacy, or whatever. I will not exercise this option without consent and consensus. Please comment below if you would be so kind. Thank you, and happy spring!

Spot-sided Coreid

Welcome to “True Bug Tuesday,” an irregularly scheduled celebration of the order Hemiptera. One of the bugs we found on our trip to south Texas earlier this month really stood out for its elegant color pattern. The Spot-sided Coreid, Hypselonotus punctiventris, was especially abundant at the Kenedy County Safety Rest Area on U.S. Highway 77, twenty miles south of Kingsville, Texas.

The rest area was landscaped with several trees and shrubs, including Yellow Trumpetbush, Tecoma stans. It was on this flowering legume that we found many specimens of the Spot-sided Coreid. It is found commonly in late October and early November in the vicinity of Austin, Texas on flowering Frostweed, Verbesina virginica.

This species apparently feeds on a variety of flowering plants as an adult. Actual known hosts upon which this insect feeds and grows include Rio Grande Abutilon (Abutilon hypoleucum), and other plants in the mallow family.

In the United States, the Spot-sided Coreid is known only from Arizona and Texas, though there is a recent record from Ashley County, Arkansas, as of April 20, 2008 (Choras III, et al., 2011). The species also occurs in Mexico, Belize, and Guatemala.

Adults average about 13 millimeters in body length, but their bold wardrobe makes them conspicuous. They can fly well, and when they open their wings they reveal a bright red patch on the dorsal (top) surface of the abdomen. Young nymphs have oversized, thickened antennae, and lack the wings adults have. I did find a final instar nymph (image below) at the Lennox Southmost Preserve, managed by The Nature Conservancy, at the very southern tip of Texas.

Despite its abundance, the Spot-sided Coreid is rarely, if ever a pest of agriculture or the garden. You are free to observe and admire this handsome insect with no fear it will doom your prize plants! Meanwhile, nearly any observations you make on H. punctiventris could represent new information on this non-pest bug.
