Pipevine Butterflies and Their Caterpillars

by Donna Lewis

So, for a while I have been talking about the really neat caterpillars of the Pipevine butterfly.  Their host plant is the Pipevine plant.  I have a naturalized Pipevine in my garden called  Aristolochia fimbriata that originally came from Brazil.  There are native ones in our area, which are very hard to see and find.

Black!

My plant is a groundcover plant not a vine.  The caterpillars will eat the plant leaves and stems down to the ground overnight once they hatch.

Then in about three weeks, the little plant regrows, and this happens four times during the summer months.  It is amazingly fast how this happens.

Black!

The Pipe-vine Butterfly produces two different colors of caterpillars!  Crazy! I do not know of another butterfly that does this.

I have looked up tons of information from many groups on this color issue. I have found that the older field guides and published books believe as the caterpillars aged, they changed colors. I do not think that is correct, after watching them for many years.

The newest theory from several universities including the latest study from The University of Virginia is that hot weather causes the red color to emerge rather than the black color. This is the current theory.

Red!

So let me throw a wrench on this theory.  Right now, today May 20th, 2022, it is really hot in my garden.  It is hot everywhere in Central Texas. And I have a grouping of both the red caterpillars and the black ones.

So how does that fit into the current findings? A real puzzle.   We will just have to keep watching and see if nature will tell us her secret.

Red!

Nature is more amazing than anything mankind can produce, and they don’t even need a computer.  Wow.

Who are you gardening for?


Sorry for the delay in blog publishing. Your poor blogger has been working too hard at her paid job and has been dealing with world events, like the rest of us. There will be catch-up blogs coming in the next few days.

Hot Weather

by Donna Lewis

I think everyone can agree it’s hot!  It’s looking like this is the new norm and will get hotter in the years to come.

We humans can go inside and enjoy a nice glass of iced tea or whatever.

But what about everything that lives outside?  Yes, they were born outside, but not in this kind of weather. So, can we help them a little without taming them?

I think so.

I just put up some heat shields on my Purple Martin Gourds. I could feel the difference it made on my face as I installed them.  Just a little help.

Cooler birds

I make sure that the many water stations I have for the birds are filled several times a day. The bees are also drinking from them. Water is so important for everything right now.

So do just a little for the wildlife we love.

Happy Trails!

More Visiting Turtles

by Donna Lewis

Hello all,

On the afternoon of Sunday, May 8, our little dog found a turtle in our yard near the house.

He barked and barked, getting my attention really fast. I was sure it must be a snake, but it was a female Red-Eared Slider (Trachemys scripta elegans) a long name for a turtle…who comes up with these names?

She was really far from the pond at the rear of our property.   Maybe she was laying eggs, who knows?

I promptly canceled my task of mowing the area. Now I’ll have to hope she didn’t bury her eggs somewhere where the tractor will roll over them. I will never be able to look for them in the pasture.  But yes (you know me) I did look.

Normally I see these turtles on the turtle dock we made on our small pond. However, these guys are crossing the roads right now, looking for a date.

If you decide to assist that journey, put them on the side of the road that they are pointed at. Make sure to wash your hands as soon as possible after handling any reptile. Happy trails…

Monarch Caterpillars in the House!

by Donna Lewis

On Maya 4, I was so happy to discover two monarch caterpillars feeding on the milkweed a group of our Master Naturalists planted on our properties last year. This species of milkweed is Asclepias asperula, common name Antelope Horns or Spider Milkweed.

Of the twenty-four plants I received from a grant Cathy Johnson procured for us, only these few survived. Gophers tunneled under all the others and they did not regrow.

But… look what found them!  There are two monarch caterpillars munching away on them.

There were also two species of bees, a wasp, a variegated fritillary, and a hairstreak butterfly.    Everyone wanted in on the action.

Interesting was the fact that the Monarchs were eating the stems not the leaves? I do not know why that was. Something to learn about.

The main thing to take away is that while it may seem like a minor event…two more monarchs made it into our world.

So yes, we can make a difference!

Volunteering at the Gault Site

by Michelle Lopez

My husband Oscar and I went to the Gault Archaeological site and helped clear huge trees and branches that had fallen during a recent tornado. Got to meet some fellow Master Naturalists from other groups. It was an honor and a pleasure to meet Dr. Mike Collins, who bought the land/site and donated it to the Archaeological Conservancy to be able to preserve it.

The entry. We are always up for more field trips here!

There was also a film crew who are in the process of making a documentary about the site. It was exciting learning about the history, and I’m still very surprised that this place has been there for so long and I only heard about it when Dr. Clark Wernecke taught an archaeological class about it. It was fun meeting him as well; he’s a very cool guy.

About the film

Olive Talley is doing an awesome job on this documentary trying to get the word out about this hugely important site that literally changes everything scientists thought they knew about when people were living here locally. This site suggests 20,000 years ago!! That’s much earlier than 13,500 previously thought for the Clovis culture. 

Clark W. explaining about the site.

Here is a link to be able to follow the documentary.
