Fall 2020 BioBlitz for Russ Pitman Park (species count)
by Eric Duran, Head Naturalist
Twice a year, the Nature Discovery Center has a BioBlitz, one in the Spring, and one in the Fall.
A bioblitz is a chance for an organization to count as many species of living things as they possibly can in a given area.
This helps us keep an eye on how populations of plants, fungi, animals, and slime molds are doing in our park (Russ Pitman Park) from year to year, as well as how living things may be faring in the Houston area. We’ll be able to understand long term trends as the years go on, and we continue to do them, as well.
A bioblitz is also a chance for our staff to better understand what’s living here in the park, and keep a detailed list of everything that may be living here (and is observable). For our naturalists and staff, its also a lot of fun!
This year’s Fall 2020 BioBlitz, just ended, and we’re happy to report the count here.
The final list is compiled, and the numbers are counted. This year we set the dates to 10/9 – 10/26, giving us a little over 2 weeks, because we had very little help with observations this year (Covid-19 being the reason).
I did most of the species observations this year, but we got help from retired Senior Naturalist Mary Ann Beauchemin, Mary Spolyar from the Native Plant Society and the Gulf Coast Master Naturalists, Office Manager Pam Dunker, naturalist and teacher Debbie Lancaster, and our community of resident birdwatchers.
This year, we counted 340 species over all, which broke down like this…
ANIMALS: (139 species)
VERTEBRATES: (50 species)
INVERTEBRATES: (89 species)
FUNGI: (36 species)
SLIME MOLDS: (1 species)
PLANTS: (164 species)
There’s nothing new and exciting to report this year, but we had a very good bird list for a Fall Bioblitz, and we identified a few small insects that hadn’t been listed in the park before. We ended up having a good insect and invertebrate count, because of the warm weather. Overall, we were up from last year’s Fall Bioblitz (our first Fall Bioblitz, as a matter of fact). We had several people helping us last year, but we actually got a higher number of species! (Last year we only had 281 species.)
Let’s hope that covid is more under control for the Spring Bioblitz 2021, which will be sometime in mid-late April.
If you have any questions about the list, or our BioBlitzes, please contact me, Head Naturalist, Eric Duran at firstname.lastname@example.org.

Fall Changes to take NDC Discovery Rooms Back to their Roots
Over the next month or so, staff at the Nature Discovery Center will be making mission driven changes to our Discovery Rooms that will take the rooms back to the Center’s roots as a place of exploration and discovery. Visitors will notice a shift in focus from indoor nature play to hands-on learning at activity and observation stations designed to ignite curiosity, understanding, and respect for nature. While we still want to encourage nature based imaginative exploration upstairs, we want to move away from indoor play for play’s sake and hopefully discourage the misuse of specimens and Discovery Room tools that have too often been incorporated into the play-based experience our visitors have had in recent years.
We are excited by these changes, and we can’t wait to see our visitors make new discoveries as they interact with natural objects, explore with kid friendly tools of the trade, “research” areas of interest in resource books, create simple nature crafts, and engage with volunteers and naturalists at themed demo and activity tables. We know there will be a period of adjustment as our visitors acclimate to our new Discovery Room philosophy, but we also know that the changes will be rewarding and worth it! Connecting kids with nature and igniting their curiosity through hands-on discovery is our passion!
What can you expect:
- removal of the Backyard Habitat house and most of the toys that have been upstairs
- a focused area for imaginative interactions with a smaller selection of puppets and stuffed animals
- a general local wildlife theme in the large discovery room with activity and observation stations
- a more focused bones, skulls, and skeletons theme in the small discovery room
- an interactive naturalist table staffed by volunteers on weekends at posted times with themed activities and/or hands-on animal encounters
- more accessible tools of the trade so that kids can explore specimens with hand lenses, rulers, microscopes, and balances, and observe wildlife through the windows with binoculars
- a “Stars of the Park” exhibit space where kids can bring in and display small curiosities and interesting objects they have discovered while exploring the park
- increased respect for our specimens and tools by staff and visitors alike
- an expectation that our visitors will help us keep the rooms clean by helping their children learn to put things back where they belong
Heather Sullivan Brings New Mindfulness Classes to Center
We’re pleased to announce a new “Mindfulness in Nature” class series being offered by Heather Sullivan at the Nature Discovery Center this spring. Practicing mindfulness in nature allows you to focus your awareness on the present moment, your thoughts and feelings, and your environment, and can help you reduce the stress that comes from leading a hectic life.
Heather, a trained Mindfulness Educator, is passionate about teaching kids and adults the tools to cope with stress and develop a more mindful approach to life in order to nurture a positive state of mind. She currently teaches a mindfulness class at Edith L. Moore Nature Sanctuary and is working with schools in Spring Branch ISD to teach mindfulness to teachers.
Heather’s Mindfulness in Nature series here in Russ Pitman Park will start on Friday, April 26 and will run for 4 weeks as a pilot program. Classes will start at 12:30 pm and will last for about an hour. You are welcome to sign up for individual dates or for the whole series.

Wildlife Wednesday: Stinging Caterpillars of Autumn
Wildlife Wednesday: Stinging Caterpillars
Autumn is time for all kinds of natural phenomena in the Houston area: bird and butterfly migration, many trees and bushes bear fruit, and leaves change color. The one common fall occurrence that most people could do without, however, is the emergence of stinging moth caterpillars. The stings of these larvae can range from mild annoyance to extreme pain, with some other mild health effects.
Caterpillars have a few ways to protect themselves. Swallowtail butterfly caterpillars have foul smelling horn like osmeteria which they use to dab nasty chemicals on potential predators. Some caterpillars can jump and wriggle wildly to escape predators. Some caterpillars have copious hairs and spines that are hard for predators to swallow. The caterpillars of some moths and butterflies have urticating hairs and spines (spines and hairs connected at the base to sacs of venom kept under the skin), that can deliver painful stings. We take a look at a few of these locally found stinging moth caterpillars today.
The most infamous of our stinging caterpillars is the Asp or the caterpillar of the Southern Flannel Moth (Megalopyge opercularis, pictured right). Asps usually emerge from their eggs in mid to late Autumn, and are commonly found in or near hardwood trees, shrubs, and vines. They feed on the leaves of these plants, and wander around constantly, looking for food, and eventually for decent locations to make their cocoons. They may be various shades of brown and gray, with a fur ridge down the middle of the back.
The infamy of these furry little larvae lie in their incredibly painful sting. Hidden in the fur ridge on their backs is a line of sharp little venomous spines. Stings from these spines may cause severe pain, nausea, light-headedness, swelling and redness of the sting site, burning sensation, and shortness of breath.
Of course, if you experience an extreme of any of these symptoms, or several of them for an extended period, you should see a medical professional for treatment. Home treatment includes removing the spines from the skin with scotch tape and topical treatment (with calamine lotion, baking soda, anti-histamine or pain relief lotions). Similar methods are recommended for other caterpillar stings, as well.
The Spiny Oak Slug (Euclea delphinii) is the caterpillar of an adorable furry little green and brown cup moth (pictured above right). While the caterpillar is really quite beautiful with its intricate designs of yellow and green or brown and orange, the pain from the stings is not at all adorable. These small spiny larvae (growing to only 2 cm long) feed on a wide variety of leaves from deciduous trees, bushes, and vines. In the South, they have 2 generations, one in the Summer, and another active in Fall.
The Saddle Back Caterpillar (Acharia stimulea) is the larva of another small and furry shiny brown cup moth (down and right) with bunches of sharp rigid stinging spines, found in bunches at the front and back and along the sides of the caterpillar’s body. This is another caterpillar with an extremely painful sting, that may cause other aforementioned symptoms. As with the other two species, they feed and are found around a wide variety of deciduous hardwood tree, bushes, and vines. They may reach a length of up to 4 cm.
Well, we hope this little mini-guide to stinging Fall caterpillars helps you stay safe out in your yard, garden, and out in area parks in the coming weeks. Though painful at times, they are important herbivores in our native ecosystems, and they really can be quite beautiful and even endearing.
Thanks for joining us again, and see you soon!

Wildlife Wednesday: The Skippers
Wildlife Wednesday: The Skippers
Spring brings butterflies back to the park, and the Skippers (family Hesperiidae) are one of the first groups to show up. These small butterflies are named for the fast darting manner in which they fly, as if they’re skipping around from flower to flower. There are over 3,500 spp. of skipper around the world, and a couple of dozen of those species are found in the Houston area. Many of the skippers look remarkably similar to each other, and can often be very difficult to identify. Many of the species are also rather drab, being various shades of brown, and can be misidentified as moths (but they are of course diurnal, and have the clubs at the tip of the antennae, which are indicative of butterflies).
Here are a few of the skippers that are found here at the Nature Discovery Center:
Fiery Skippers (Hylephila phyleus) are one of the more common species found here, visiting our wildflower gardens, wildflowers on the front lawn, and the Pocket Prairie. The males are a bit showier, with bright orange and dark brown on the wings (pictured left and top), and the females are a light yellowy brown with brown spots. The tiny greenish caterpillars feed on a variety of grasses, including Bermuda grass and St. Augustine grass. You may notice that this skipper keeps its forewings and hindwings separated at a right angle, with the forewings held up, when it’s resting. This is a small butterfly, measuring only about 1 in long.
The White Checkered Skipper (Pyrgus albescens) is easy to tell apart from most other skippers with its white and dark gray/black checkered pattern. There is however, another checkered skipper that is very similar to this species, the Tropical Checkered Skipper, which is also found in our area. They visit a wide variety of small flowers close to the ground, and their caterpillars feed on a variety of small mallow/hibiscus species, like Sida. They may attain a wingspan of up to 3.8 cm in width.
Juvenal’s Duskywing (Erynnis juvenalis) is one of 2 species of Duskywing (dark colored skippers that keep their wings open and flattened when on a perch), found in our park. The other is the very similar Horace’s Duskywing, though there are many other species of Duskywing across the country. The caterpillars of these skippers feed on oak leaves. They are similar in size to the Checkered skippers, ~3.8 cm wingspan. Duskywings can make themselves rather conspicuous with their darting, climbing, and diving flight patterns, and their habit of sunning out in flat open meadows in plain sight.
We hope you enjoyed our profile of a few skipper butterflies common to our park. Come out and walk around our wildflower gardens, Prairie Wetlands, and Pocket Prairie, the next time you get the chance, and see if you can spot these delightful little insects.
Thanks so much, and see you soon!
