NABA Butterfly Count 2015!

As usual, the North American Butterfly Association’s Butterfly Count started at 9 am in Lick Creek Park. Our resident butterfly expert (Bruce, of course!) was out of town so the group was led by another local expert, Jim Snyder.  Volunteers consisted of Rio Brazos Audubon members, TMN members and people with no affilation who heard about the count and just showed up.  We were also joined by several members of the NABA Houston group and they were a big help to us beginners! 



Volunteers at Lick Creek Park


It was a successful day overall!  Twenty (!!) volunteers started at Lick Creek Park in the morning.  It was a GREAT turnout!  After lunch with the heat of the day upon us, the numbers dropped to nine volunteers combing though Millican Reserve and Bee Creek Park.  At Lick Creek Park we didn’t see any Zebra Heliconian like we had last weekend on Bruce’s butterfly walk.  Maybe Rick photographed the demise of the last one mid-week!  Who knew that dragonflies eat butterflies?!

At Millican Reserve there were so many dragonflies the butterfly numbers were pretty low.  We actually saw Common or White Checkerspot-skippers fleeing from dragonflies.

Bee Creek Park brought a renewed vigor to the search… maybe it was the just the heat getting to us!  But we did add several new species to the list.

Of course, butterflies don’t pose on demand and it can be frustrating to try and identify them on the fly.  That’s ok, we had plenty of other critters to look at!

It was a wonderful count day!  If you couldn’t attend and still want to see butterflies, they’re still around.  You don’t have to walk miles through Lick Creek Park to see them, either.  Gardens throughout town should have butterflies visiting nectar plants. 

Thanks to everyone who came out!  Have a wonderful timing watching butterflies during the summer months!

Up In The Air.....

It’s a bird, it’s a plane, it’s a…. meteor?!?  I like to call meteors “Nature’s fireworks”.   With the Fourth of July this weekend, instead of writing about mini-rockets explode in the sky, I’d thought I’d write about…. well, rocks exploding in the sky!

There are a lot of phenomena that can be considered Nature’s fireworks… lightning, the aurora, volcanic eruptions… but none can really compare to a meteor shower.

Meteor Showers
A meteor shower occurs when cosmic debris enters Earth’s atmosphere and burns up.  Most of the time the pieces are small, about the size of a sand grain, so they will completely burn up and never reach the Earth’s surface.

Meteor showers have a periodicity and are predictable at certain times of the year.  These events are related to comets passing close to the Earth and shedding debris.  Think about Halley’s Comet coming around every 75 years.  It was last here in 1986 and will return again in 2061.  The comet has passed by Earth many times and left debris along some of its previous paths.  There are two meteor showers associated with the debris trails: the Eta Aquariids occurring in April and May, originating near the constellation Aquarius, and the Orionids, originating from the constellation Orion in October.  You can check out StarDate.Org for the 2015 schedule of meteor showers.   The next one is coming up in August!

Meteorites
Sometimes, cosmic debris is big enough to not burn up upon atmospheric entry and will hit the Earth’s surface.  Now we call them meteorites. 

Meteorites are pretty cool because they can tell you a lot about the origin of the larger extraterrestrial body they came from.  For example, a stony meteorite comes from the rocky crust of a small planet (planetoid) while an iron meteorite comes from the core of a planetoid. 

Now, Texas is a great place to see meteorites and their craters.  Most notable, is the Odessa Crater.  Odessa is interesting because it is young enough for the crater to still be seen (only 25,000 years old!) and has plenty of iron meteorite fragments.  It is also has a nice little museum/gift shop and is free and open to the public.  If you are ever out in west Texas along Highway 20, stop in and check it out!

Fireballs
Finally, cosmic debris can sometime enter Earth’s atmosphere but just skims the surface and returns to space.  These events are called fireballs.  As recently as last year, a large fireball was seen in central Texas.

Since we probably don’t want to wait until August for a meteor shower or the random fireball that streaks across the sky to satisfy our love of nature’s fireworks, it’s probably easier to go out to the local firework display and enjoy the show!

This weekend, be safe and enjoy the (man-made) fireworks!

April Showers Bring May.....

I bet you thought I was going to say “flowers”!  Well, spring rains bring flowers but they also bring trash to our greenways, streams, and parks.  Within the past week and a half TMN members have participated in two trash clean up events at local parks and trails.  The first was on April 26th and involved trash collection along the Carter Creek Trail and retention pond near the Brazos Valley Museum of Natural History in Bryan.  This event included TMN members and several geocachers… people who “use GPS to find Tupperware hidden in the woods”.  The goal was the same for both groups though… clean up the trash! 


The TMNers who cleaned up Carter Creek Trail... minus Jackie who had already left.  Thanks for your help!


We did a great job removing 12+ bags of trash from the area… most of it being washed in along Carter Creek or from the nearby big box store parking lots.  We picked up trash and rocked to oldies music provided by the classic auto show going on in the parking area.


Trash removed along Carter Creek Trail and the retention pond behind the Brazos Museum of Natural History in Bryan.


The second clean up event occurred this past weekend on May 2nd at Gabbard and Brison Parks in College Station.  These parks were adopted by the Chapter through the City of College Station’s Adopt-a-Greenway program and we will be going out at least twice a year to pick up trash.  The City will put a sign up letting the public know the Chapter is involved with keeping the parks clean.  Not a bad deal!

Five TMNers participated and within about 2 hours we removed 10 bags worth of trash.  Again, most of the trash being plastic stuff along the waterway (Bee Creek).  This time the hazards included poison ivy which is all over Brison Park, thorns, mud, and mosquitos.

PLASTIC is the big problem!  Please urge neighbors, family members, and friends to use reusable bags when shopping!!  We weren’t able to clean up all the plastic trash along the stream at Brison Park… the thorns and underbrush (and poison ivy!) were just too thick in some places.  We hope to plan a more extensive clean-up along the waterway in the late fall or winter when the plants die back a bit.

Thanks to everyone who came out to clean-up!  If you weren’t able to make it this time around I hope you can come out next time!

Wildflowers of Spring!

The signs of spring are all around!  Birds are coming back and wildflowers are blooming along the roadsides.  The flowers are nice to look at but also can act as a needed food source to insects, butterflies and birds.  This blog post discusses (in no particular order) some of the more common wildflowers coming up right now.


Texas Bluebonnet Lupinus texensis and Indian Blanket Gaillardia pulchella:

The Texas Bluebonnet is our state flower!  You know when spring is here when the bluebonnets start coming up.  Bluebonnets are members of the Pea family and are a beneficial flower for butterflies and native bumble bees.  Additionally, they are the larval host for the Hairstreak and Elfin butterflies.

The Indian Blanket is a long lasting flower that will brighten any garden when blooming.  It is a member of the Aster family and the orange and yellow blooms will attract butterflies.


Black-eyed Susan  Rudbeckia hirta and Indian Paintbrush Castilleja indivisa

Black-eyed Susan is a well-known flower commonly seen throughout the United States from the late spring to early fall months.  It is a member of the Aster family.  Black-eyed Susan flowers are beneficial to many creatures; the seeds are eaten by birds and nectar eaten by bees, insects, and butterflies. 

Just like the Texas bluebonnet, Indian Paintbrush is a common sight around town in the spring.  It is a member of the Figwort family.  Insects, butterflies, and hummingbirds are attracted to the bright red blooms and the plant is the larval host for the Buckeye butterfly.


Winecup Callirhoe involucrate and Plains Coreopsis Coreopsis tinctoria

The Winecup is a poppy-like member of the Mallow family and common in Texas in the early spring.  It will attract native bees and butterflies.  It is the larval host for the Gray Hairstreak butterfly.

Another member of the Aster family!  Plains Coreopsis is a cheery flower and is common throughout most of the United States in the spring and early summer.  Bees, insects, and butterflies eat nectar produced by the plant while seeds are eaten by birds. 


Prairie Verbena Glandularia bipinnatifida var. bipinnatifida and Lemon Mint Monarda citridora

The Prairie Verbena is a nice touch of purple in hillslopes of red and yellow.  It is a member of the Verbena family.  The flower blooms from spring until winter and will attract birds and butterflies.

Lemon Mint is a member of the…. Mint family!  Bumble bees especially like the upright blooms.  Butterflies, insects and hummingbirds will also be attracted to the blooms.


Purple Coneflower Echinacea purpurea and Pink Evening Primrose Oenothera speciosa

The Purple Coneflower is our last member of the Aster family for today.  An interesting fact, the genus, echino, means “hedgehog” for the spiky cone in the middle.  The purple blooms will attract butterflies and hummingbirds. 

The Pink Evening Primrose is a member of the Evening-Primrose family.  These dainty flowers are common throughout most of the United States and the seed capsules will attract birds.  


Seed balls: A great project for kids or anyone!

I know what you’re thinking… these flowers would be great in a native wildflower garden… right?  Well, you can make that happen!  This combination of native wildflower seeds is being sold by the Native American Seed, a company recommended by the Lady Bird Johnson Wildflower Center.  The blend of seeds is suited for central Texas and is called the Lady Bird’s Legacy Wildflower Mix.  A portion of the sales goes to the Wildflower Center Seed Grant program.  From the Seed Grant website:

 "The Lady Bird Johnson Wildflower Center in partnership with Native American Seed awards grants of seed (Seed Grants) to Texas schools (K-12) that support the Wildflower Center’s mission to increase the sustainable use and conservation of native wildflowers, plants and landscapes. Seed grants can be used to establish wildflower demonstration areas, to enhance existing wildflower sites, or in other educationally directed projects."


So buying seeds will help get kids involved and learning about native plants... it’s a win-win situation!  Ok, now that you have seeds, what do you do?  You can plant them traditionally or another way to get kids involved is to make seed balls. 

Seed balls are composed of clay, compost, and seeds with some recipe variations involving sand.  Basically, mix the dry ingredients together and add enough water to make the clay sticky.  Pinch off small pieces of the clay and roll into balls between your hands.  It will take a day or two to dry completely.  Now, you can throw the seed balls into a patch of yard and soon you will have a beautiful wildflower garden!

Happy Spring!
