2nd Annual Lake Arlington Garden Biosurvey – Oct. 15th

Arlington Water Utilities and Tarrant Regional Water District have partnered to create a native plant demonstration garden with 2,000 sq. ft. of flowering native perennials and grasses on city-owned land adjacent to the Lake Arlington Dam. We will be seeding a native wildflower meadow in the surrounding 3 acres in November. In an effort to understand the impacts of these projects on local wildlife, we would love your help documenting existing biodiversity on the site.*

We are hosting our 2nd annual biosurvey on Saturday, Oct. 15th from 8am to 10pm. Please sign up at this link to help! Once you register, we will send you directions to the site, instructions for entering the gate and signing in, and a map of the area to explore.

*The project site is surrounded by low-lying fields with wetland vegetation and bordered by native trees and lake shore. On the 3 acres around the demonstration garden, there is a field of low-growing forbs and grasses which are being treated to remove invasive grasses. The site is owned by Arlington Water Utilities and only accessible with permission via a gated entrance.

Here is the project from the 1st annual biosurvey so you can see what we found last year:

My new gall wasp species is official! 🥳

If you've been in any conversation with me in the last year, it probably included a fair amount of excitement that I was describing a new species of gall wasp with some colleagues. (Not to belittle their involvement in any way! It was a team effort. Now back to the bragging...) Today our paper has been formally published, so I'm going to brag a little bit longer! Plus, it includes some bonus content about other things I've been working on, too.

Discovery through iNaturalist: new species and new records of oak gall wasps (Hymenoptera: Cynipidae: Cynipini) from Texas, USA.
Y. Miles Zhang, Kimberlie Sasan, Robert J. O'Kennon, Adam J. Kranz
July 20, 2022

Abstract: A new species of the genus Druon Kinsey, 1937, D. laceyi Zhang, Sasan & O’Kennon sp. nov. is described on host plant Quercus laceyi Small from central Texas. We also re-establish Andricus lustrans Beutenmüller, 1913 comb.rev., and transfer Striatoandricus aciculatus (Beutenmüller, 1909) comb. nov. from Andricus. Finally, we report a new state and host record for Druon gregori Melika, Nicholls & Stone, 2022. All observations were first shared on the social platform iNaturalist, highlighting the potential of cybertaxonomy in uncovering overlooked biodiversity.

Allow me to introduce you to... Druon laceyi

If you are interested in reading the full paper, PM me. Miles did a fantastic job of describing the wasp in words the rest of us can hardly understand.

Identifying Triodanis - Venus's Looking Glass Flowers

I've put together a fairly basic ID chart for ID'ing Triodanis flowers to species. This is a living document, so it may have changes made without notice. I suggest bookmarking the following link instead of downloading the document:

For questions/comments about the document, please PM me directly. For questions about ID'ing a particular observation, please tag me in the observation using @kimberlietx

Kermesidae: Gall-like scale insects of Texas

In researching IDs for gall-like scale insects I found a site that made ranges easy to search. Scalenet.info has some great information, but not enough (that I saw) to properly ID scale insects in the gall-looking form we usually photograph. With this information, it looks like Texas Kermesidae should primarily be ID'ed at the family level except for on Live Oaks which can be Genus Allokermes.


The following list are my commonly seen oaks in DFW, but you can find all hosts and Kermesidae ranges on the site.

Quercus stellata (Post Oak)
Kermes pubescens, Kermes sylvestris, Allokermes galliformis

Quercus marilandica (Blackjack Oak)
Kermes pubescens, Allokermes galliformis

Quercus macrocarpa (Bur Oak)
Kermes pubescens, Allokermes galliformis

Quercus virginiana (Live Oak)
Allokermes cueroensis, Allokermes galliformis

How you can easily make virus observations

James Douch wrote a great post on the iNat Forum about how to make observations of viruses and he couldn't have made it any easier! Here's a way to keep your eyes open for new species! And James is great about helping out if you want to tag him in your observations!

Read the full post here:

"However, few iNaturalists are even aware that viruses may be observed on iNaturalist, and the number and diversity of virus observations is low. Of course, many viruses cannot be detected without laboratory techniques, but this is not always true. I would like to provide some suggestions on how you can easily make your first virus observation." ~James K. Douch

Oct 16th - Volunteers needed for biosurvey of future Lake Arlington Native Garden site.

Arlington Water Utilities and Tarrant Regional Water District are teaming up to create a native plant demonstration garden and prairie restoration at the Lake Arlington Spillway. Before any construction efforts get underway this fall, we would love your help documenting existing biodiversity on the site. The project site is currently a field of low-growing grasses and forbs, both native and non-native, surrounded by low-lying fields with wetland vegetation and bordered by native trees. The site is owned by Arlington Water Utilities and only accessible with permission via a gated entrance.

We are hosting our first biosurvey on Saturday, Oct. 16th from 8am to 10pm. We would love to have anyone interested to join us in documenting the flora and fauna of the site. You can come anytime throughout the day and stay as long or as little as you like. Snacks will be provided under a covered area with chairs for relaxing and socializing.

If you are interested in volunteering, please sign up at this link: https://www.signupgenius.com/go/10c0f4eaaaa2ea4fcc61-lake. After registration, we will send an email with directions to the site, instructions for entering the gate and signing in, and a map of the area to explore. If you would like more information not included here, please contact Kimberlie Sasan on iNaturalist at @kimberlietx or by email at kimberlietx@gmail.com.

Triodanis Quick Tips

If you've been trying to figure out how to ID which species of Triodanis flower you have seen, this post is intended to give you a quick and simple way for the two most common species in Texas and the US: Triodanis perfoliata "Clasping Venus's Looking Glass" and Triodanis biflora "Venus' Looking-Glass". I'll create a more detailed key to all seven of the species soon, but until then feel free to tag me in your observations or send me a direct message if you need help.

Photograph the stem so you can see the leaves and the fruiting capsule. To identify to species you will want to to see where the pore ("window") is located.

Here's an example of T. perfoliata fruit with the pore in the middle. It also has leaves that wrap around the stem ("clasping").
(Click on the picture to go to the observation.)

Here's an example of T. biflora fruit with the pore at the apex. Also, the leaves are simply attached, not wrapping.

Maps to Texas soil types

In my study of a couple of particular plant species it has been helpful to see soil maps and compare them with what is known about the plants' soil needs. I've been using USGS geologic maps overlayed on Google Earth. I thought some other folks might find this resource helpful.

  1. First, download the USGS Texas geologic KML file here:
    Click on the link for "txgeol.kml" Uncompressed version and save it to your computer (in a location you can find.)

  2. Next, navigate to Google Earth: https://earth.google.com/web/. If you have not used it before, it could take a while to download completely. (There should be a completion % at the bottom left of the screen.)

  3. Once Google Earth has completely loaded, find the symbol on the left side of the screen for "Projects". Click on "New Project" and select "Import from KML file on computer". Navigate to where you saved the txgeol.kml file earlier. Again, it may take some time to load the file. You will see it begin to add an overlay to the globe, but wait until it is at 100% before trying to search for a location.

  4. Once it's completely loaded, you can now search for an address or GPS coordinates. Right click on the location and a box will pop up telling you the name of the geologic group. Click on "Detailed description" to find out the soil composition and more details. Here's an example of the map view and the soil description:
