Tree Following: Texas Retama in November 2014

I’m happy to participate for the first time with Lucy and her Tree Following meme which is celebrated on the 7th of every month on Loose and Leafy blog.    I discovered this charming gardening meme while researching garden blogging memes and it appeals to me.  I relish the idea of a month-to-month, year-long study of a particular garden subject through its seasonal and gardening changes.

So, my tree for the coming year will be–drumroll please–the Retama, Parkinsonia aculeata, which is living happily in my garden in Austin, Texas, USA.

My Retama is situated in a moderate-sized urban garden, flanked on its right by a large, native Red Oak tree and a smaller native Mountain Laurel tree and on its left by a non-native Crepe Myrtle (which belongs to the back neighbor).   Also and unfortunately, during the coming year of Retama-watching, we’ll have to tolerate the unattractive electric lines which span unceremoniously across the back of my property and will  appear in many of the Retama photos.

IMGP2297.new

Yuck.  I don’t see those lines when I stroll my garden, gazing admiringly at the Retama or other garden pretties,  but I certainly notice them in photographs.

I just want you to know that I know the lines are there.

We’ll cover the basics today, accompanied by some November Retama photos. The Retama,  Paloverde,  Mexican Palo Verde, Jerusalem thorn, and  Lluvia de Oro is a native-to-Texas tree with many names, it seems.  Its native range is Central Texas, west to Arizona and southward to South America.  It’s a small tree, usually 15-20 feet tall, with airy foliage and yellow bloom clusters in the summer months.

Silhouetted against a gray sky, its foliage and branch forms are graceful and elegant.

The bright green, tiny leaves are borne along a pair of stalks, opposite one-another.

IMGP2302.new

IMGP2307.new

The fine foliage gives a feathery, soft appearance to the tree.  The Retama is deciduous, but the bark remains green, even during winter.

IMGP2305.new

The bark is completely green when the tree is young, developing a layering of textured orangy-brown bark as the tree ages, though the green bark remains a characteristic feature.  The bark reminds me of the outer layer of cantaloupe.

IMGP2306.new

Thorns grow along the branches,

IMGP2310.new

…and yes, those thorns hurt when the gardener bumps against them while working around the tree.  Which I’ve done.  Numerous times.

IMGP2311.new

Ouch!

The seed pods are typical legumes, which makes some sense as this tree is in the Pea (Fabaceae) family.

IMGP2309_cropped_3147x3304..new

The blooms are gone on my Retama as it is well into autumn, with shorter days and cooler temperatures.   But the tree remains attractive and useful for the birds, like this migrating Blue-gray Gnatcatcher.

IMGP1603_cropped_3037x2903..new

The tree is a favorite of many birds.

Retama.

When I was growing up, my mother called it Palo Verde.  I’m not quite sure why I don’t use that moniker for this beautiful tree, but by whatever name it’s called, Retama is lovely and unusual and I look forward to studying it more closely this next year.

Thanks to Lucy for hosting Tree Following–please pop over to Loose and Leafy and check out trees being followed from all over the world.

Wildlife Wednesday, November 2014

I should call this month’s post: what you notice when you bother to pay attention.  The reason I started Wildlife Wednesday was (unselfishly)  to promote planting and gardening for wildlife and (selfishly) to improve my own observation, identification, and photographic skills.  One thing I’ve learned is just how much wildlife actually resides in my gardens that I hadn’t fully appreciated.  I wasn’t oblivious to the myriad of creepy, crawly, flitty pollinator/seed distributor-types, but I didn’t notice them all that much.  Bees?  Oh sure, they’re in the garden, but don’t ask me to tell the difference between species.  The birds were easy to identify, as long as they were colorful or in some other way caught my eye. All those little brown/gray/tan things?  They were just “twitty birds” to me.  Butterflies, because of their obvious beauty, were much easier to discern, but I didn’t necessarily observe and identify moths or the many little skippers out there, which are important pollinators, along with the most beautiful butterfly. I’m still more likely to be aware of the conspicuous; sometimes, that’s all I have time or patience for.  But in these past few months, in focusing my observations on life-beyond-the-plants, I’m amazed at what I’ve seen that I wasn’t aware of.  I have grown to value, even more than before, the abundant diversity residing in my patch of the Earth.

I must have spent fifteen minutes attempting to get a decent photograph of this pollen-heavy leafcutting bee,

IMGP0964.new

..as it worked the blooms of a Henry Duelberg Sage.  At least I think it’s a leafcutting bee, which is categorized as a Megachile species.   I was more fascinated at how this little bee moved around, so laden  with pollen.  At one point she rested along the stem.

IMGP0954_cropped_3709x2742..new

Just afterwards, she lumbered away in flight, her corbiculae, which I like to call pollen pantaloons, loaded with valuable cargo.  Honestly, I wasn’t sure she could fly, she was carrying so much pollen.  But fly she did.

Throughout this blooming fall, I’ve seen many individuals of this species of Tachinid fly at blooming plants, like Frostweed.

IMGP1062.new

The first of these flies that I saw was at a distance and  I assumed it was some sort of black bumblebee.  Upon closer inspection,

IMGP1072.new

…it had that definite fly look about it. Those huge eyes!  And don’t you just love those hairs sticking out of its abdomen?

IMGP1065.new

Interestingly, I’ve observed these flies exclusively on the Frostweed and White Mistflower blooms–both white flowers, though I couldn’t find any information that suggests they prefer white blooms.

Of course, I must brag about my little honeybees,

IMGP1790_cropped_3806x3346..new IMGP1569.new

…as they work flowers for the benefit of the hive(s).

Throughout October, I’ve seen several types of hover fly species in the gardens.  The Common Oblique Syrphid, Allograpta obliqua, is remarkably photogenic.

IMGP1634.new

IMGP1639.new

This little “flower fly” is a beneficial garden resident as it sips nectar in its adult stage and controls aphids in its larval stage, as a little green worm.  Beautiful to look at and valuable for gardens,

IMGP1641.new

…they’re good garden partners.

And of course, no parade of October-in-Austin insect photos are complete without a bevy of butterfly images.  The Monarchs, Danaus plexippus,  have been daily visitors through most of October, nectaring on favorites like the Gregg’s Mistflower.

IMGP2001.new

A relative of the Monarchs,  the Queen, Danaus gilippus, also prefers Gregg’s Mistflower,

IMGP2057.new

…as does the American Painted Lady, Vanessa virginiensis,

IMGP2060_cropped_3415x3078..new IMGP2086.new

IMGP2079.new

…as does the Mournful Duskywing, Erynnis tristis.  

IMGP2090_cropped_3433x3253..new IMGP2095_cropped_3783x3133..new

I guess the garden lesson demonstrated here is that Gregg’s Mistflower is a must-have wildlife attracting plant.  It’s pretty, too.

Common in Austin, the Pipevine Swallowtail, Battus philenor,  is a high, strong flyer. Though this one,

IMGP2202.new

IMGP2205.new

…looks a little worse for wear.  It was nice to see him one sunny afternoon, because I haven’t enjoyed many of his kind visiting my gardens this year.

As we head into cooler temperatures, the various dragon and damselflies will be dormant. I spied this beauty, a Springwater Dancer,  Argia plana, sunning himself on the rocks which border my pond.

IMGP2101_cropped_3663x3225..new

He may be the last one I see this autumn, but I’m sure he and his Odonata brethren will return next spring to grace my gardens.

I think this little insect is a sweat bee of the Halictidae family.  He/she was busily working a Goldeneye bloom. Small bloom, smaller bee.  I thought that I would definitely find a photo and identifying information for this critter, but didn’t locate information which gives me total confidence on my identification. I’ll have to take a guess on this one.

IMGP2151.new

But it’s an example of what you notice when you pay attention.  Unobtrusive and small, I might not have seen this native bee (of whatever variety) if I wasn’t looking for wild visitors.

This Blue-gray Gnatcatcher, Polioptila caerulea, was hopping around in my Retama tree one Sunday afternoon as I attempted to photograph a Tufted titmouse.

IMGP1600_cropped_3327x2926..new

The Gnatcatcher is apparently a summer resident in Central Texas, before migrating south, but I don’t know that I’ve ever seen one before.

IMGP1601_cropped_3788x2940..new

More than likely I have seen a Gnatcatcher, but relegated it to the category of “generic neutral-colored bird,” which I’m afraid I sometimes do.   My bad.

IMGP1602_cropped_2829x3170..new

He’s another example of what you notice when you pay attention.  And I never did get a decent photo of a Tufted titmouse.

This American Redstart, Setophaga ruticilla, visited and this is the best shot I could manage. IMGP1652_cropped_2695x3304..new

The photo is poor quality, in part because I was so excited to find a bird that I’d never seen (I need to work on that breathe deep and focus thing), but also because he was flitty and flighty in his movements.  Then my dog waddled near to where the bird was.  Then the cat decided to stroll in the general vicinity of Mr. Redstart.  Well, he’s no fool and he flew away. Migratory through Central Texas, on his way to Central and South America for winter, I saw him a little later in an oak tree, but it was late and he just wouldn’t cooperate for a photo.  After looking at photos of both the male and female Redstarts, I believe I observed a female mid-month working her way among my perennial shrubs.   Alas, no photo of her either.

The Lesser Goldfinches, Spinus psaltria, descended on the Goldeneye as the flowers went to seed.

IMGP1968_cropped_2940x3332..new

IMGP2065_cropped_3290x3341..new

They were around for a week or two, making themselves at home.

IMGP2062_cropped_3046x3359..new

I haven’t seen them in about two weeks.  I live on the edge of their year round habitat, but it’s possible the visiting crew headed south.  I did read that they tend to move around quite a bit.  I still have Goldeneye seeding out;  I wish the Lessers would stop by for some meals.

And I’m always amaze at the noise the petite Carolina Wren, Thryothorus ludovicianus, makes.

IMGP2200.new

This little guy is a common bird in my gardens and packs a wallop of sound from that tiny body.  This fellow was singing away just after sunrise.

Lots happened in my garden during October and I’m sure yours also hosted plenty of wild action. Please join in posting about the wild garden visitors for November Wildlife Wednesday. Share the rare or mundane, funny or fascinating, beneficial or harmful critters you encounter. When you comment on my post, please remember to leave a link to your Wildlife Wednesday post so we can enjoy a variety of garden wildlife observations.

Good wildlife gardening to you!

Trav’lin Monarchs

As of this past weekend, migrating Monarchs are gone from my gardens.  We received our strongest cold front of the season and like other winged migrators, Monarchs hitch a ride on those strong winds heading southward. I did visit the Lady Bird Johnson Wildflower Center over the weekend and saw busily nectaring Monarchs there–maybe those were some that left my garden a day or two before.  While the Monarchs’ migratory patterns and their winter habitat are seriously threatened, causing concern for the future of this North American species, I was gratified to host Monarchs in my gardens over the past few weeks. Every afternoon, there were several,

IMGP1157.new …sipping and sharing with other pollinators.

IMGP1160.new IMGP1166.new

The perennials in my gardens cooperated, supplying blooms galore for the Monarchs’ winter needs.  They especially enjoyed the blooms of the Frostweed, Verbesina virginica.

IMGP1167.new IMGP1169.new

Any migration worth its mileage will have both males and females along for the adventure. How do you know whether it’s a boy Monarch or a girl Monarch?  The male Monarchs tend to have thinner wing veins than females, therefore are lighter in color. More easily observed though are the black spots on the hind wings which have pheromones which attract the ladies.  Can you see the black spot in this photo?

IMGP1995.new

It’s located on  the underside of the hind wing, just above where the “B” for the label is.

 

In this photo with wings spread, the gentleman’s black spots are to the left of the label.

IMGP1997.new

This Monarch, dining on nectar of the Gregg’s Mistflower, Conoclinium greggii, 

IMGP2007.new …is female.  As is the one below, sipping on a  Blue Mistflower, Conoclinium coelestinum.

IMGP2111.new

There are no discernible spots on either, so they are female.  Read here and here for a couple of excellent tutorials on sexing Monarchs.

I wish good travels to the Monarchs out there and safe harbor in the mountains of Mexico. I’ll await your return in the spring, with blooms ready to help continue your remarkable life cycle.
