Resting and Robbing

Bees are busy pollinating the summer garden, but like the rest of us, they need rest. Foraging is hard work! This Horsefly-like Carpenter bee, Xylocopa tabaniformis, chose a pretty pink bougainvillea bract as its preferred napping spot.

I watched it for some time as I puttered in the garden and it didn’t move. I’ve seen bees “sleep” on flowers in the past, usually on petals or atop leaves. I’m sure they rest in other places too, but it’s likely that those spots are more private, less noticed by the perspiring gardener. I checked the plant after puttering and the bee had moved on.

This Southern Carpenter bee, Xylocopa micans, participating in nectar robbing, is poised to poke its proboscis into the bloom of a Big Red Sage, Salvia penstemonoides.

Nectar robbing or nectar stealing is a way that various insects, bats, birds, and mammals consume nectar without the benefit to the plant of pollination. In the case of bees, they typically bite or poke a hole in the petal tissue, then sip the nectar, bypassing the parts of the flower where pollination happens. Flowers can be damaged by the robbing, thus preventing further visits from pollinators. As well, some pollinators also recognize when a bloom has been robbed of its nectar, so they move on to other nectar-filled flowers, the robbed flower missing out on pollination. For for various reasons, nectar robbing isn’t generally considered harmful for plants or an ecosystem as a whole, but is simply part of the functional tapestry of a diverse natural space.

Carpenter bees nectar rob because they’re such big bees they can’t fit into certain blooms. Generally, the blooms that bigger bees rob have slender, tubular corollas. This same Southern Carpenter bee is head-and-proboscis-deep into the base of the Big Red sage bloom, sipping the sweet stuff available. There’s no way that big body could nestle in the bloom.

Sometimes, a robber is sprinkled with pollen, perhaps due to buzz pollination. Buzz pollination happens when certain bees vibrate their strong thoracic muscles, vibrating, or sonicating, the pollen grains from flowers’ anthers. During foraging, this Horsefly-like Carpenter bee might have buzzed pollinated on a different flower, its back carrying sprinkles from the loosened pollen onward through the garden. The bee is too big to crawl into this bloom, a Henry Duelberg sage, Salvia farinacea, so stealing is the way to go.

Of course, there are those who pollinate the old-fashioned way, crawling all over a bloom, collecting pollen as they go! This native bee, perhaps a Mining bee, Andrenidae, or a Plasterer bee, Colletidae, enthusiastically worked the flower of a Texas thistle, Cirsium texanum.

Pollinating or robbing, it’s a busy time in the summer garden, especially for those who live in and rely on its bounty. After a hard day in the garden, sleep is bliss.

Winged, and Other Things: Wildlife Wednesday, September 2018

Just a quick howdy do!  for September’s Wildlife Wednesday, recapping a few flitting winged things from this past month.  August is typically hot and quiet, but the garden and its inhabitants remain full of energy and life, even when the gardener drags.

For this whole growing season, I haven’t snagged one good photo of my favorite native bee, the Horsefly-like Carpenter beeXylocopa  tabaniformis.

Bee butt-view on a Turk’s cap bloom.

There are many of these busily buzzing, nectar-stealing carpenter bees in my garden, but this is the best shot I’ve managed this year.  I’m either too slow with the click, or choose a ridiculously windy day to shoot, or am distracted and lose sight of my subject.  The bees keep their cool though, working the garden, laying eggs for the next generation, and taunting the gardener with their charm. There’s still plenty of time to work on attaining some decent photos before the days are significantly shortened and these bees bed down for winter.  Stay tuned!

I’m continuing to enjoy the Turk’s cap visits of several Southern Carpenter beesXylocopa micans.

Like the Horsefly-like carpenter bees, the Southern Carpenter bees nectar-steal and favor Turk’s caps blooms, though I have also seen them at the brilliantly blue, Majestic sage blooms.

These bees are so large, they are easy to spot in the garden, even from a distance.

 

The big butterflies are now more common, as is typical for the late summer.  This Eastern Tiger Swallowtail, Papilio glaucus, nectared at the dramatic flowers on one of my Mexican Orchid trees, which is a favorite of a variety of bees and butterflies.

 

It took me some time perusing Austin area iNaturalist photos to identify this emerging moth as a Virginia creeper SphinxDarapsa myron.

Top-view,

…and the underside.

I love his/her little face and tiny chocolate-drop eyes.  Some bird-delivered Virginia creeper (the host plant for this moth), growing in my back garden, was probably the food source for the moth in larval stage.  This adult emerged in late afternoon from a chrysalis situated on a branch of a Drummond’s ruellia.

 

The dragons and damsels zoom throughout my garden, but perch near the pond.  I think this is a female Dusky DancerArgia translata.  

The damsel was in nearly constant motion and I took the photo at a distance, so for identification purposes, the photo is not as clear as I’d like.   The Dusky Dancer is a common predator and widespread in Texas.  The purple eyes are a marked feature for this particular species, so I’m reasonably confident I got this right.

 

This Pipevine SwallowtailBattus philenor, has certainly seen better days.

I’m now growing pipevine plant and am enjoying more of these beauties as they float through the garden.

 

Early one morning I caught this fella nectaring on the salmon blooms of one of my Red Yucca plants.

This Leptoglossus phyllopus is one of the many leaf-footed bugs common in this region and they do fly.

 

No wings here, but the look on Mr. Green Anole suggests he’s weary of summer and ready for autumn.  Or, maybe I’m just anthropomorphizing.

Yeah, that’s it.

I love these little guys and gals and they’ll be around until our chill arrives, which is months away.

Movin’ On: Wildlife Wednesday, April 2017

It’s springtime here in Austin, Texas and there’s plenty to relish, especially regarding the many gifts of nature:  pleasant temperatures, glorious sunshine and well-appointed rainfall, iconic wildflowers and other blooming beauties, and active and abundant urban wildlife. You don’t have to go far–there’s no requirement for lengthy drives into the Hill County or blister-producing hikes–to savor  the benefits of spring pleasures if you plant for wildlife in your own garden space.   When you grow native annuals, perennials and trees, as well as adapted non-native plants, you will reap a blooming bonanza in your garden.  Wildlife of all sorts will come, as they’re granted rest and reprieve, nourishment and protection, most especially during migration and into the breeding season.  Welcome to Wildlife Wednesday where we showcase wildlife and appreciate their place in our own back yards and in the larger world.

This past month I  haven’t observed the variety of migratory birds that I recall from 2016, but there were a few who made brief stops near the pond, or who rested in newly foliaged Red Oaks.  A pretty White-eyed Vireo, Vireo griseus, a lone and stunning Black and White Warbler, Mniotilta varia, a handsome Dark-eyed Junco, Junco hyemalis, and four female Red-winged Blackbirds, Agelaius phoeniceus,(obviously engaged in a girls’ day out), comprise the sum total of spring migratory birds gracing my garden.  With each observance, I either didn’t have my camera ready, or chose to simply marvel at the bird’s presence;  I have no photos of these birds to share.

My avian winter Texans visit the back garden less frequently and I assume that most have moved on to more northern gardens and greenbelts, with the hope of a mate and chicks.   I haven’t seen any Orange-crowned Warblers, Oreothlypis celata in several weeks, but throughout winter and earlier in March, one, or several, were daily garden charmers as they perched on limbs or hunted for insects from spring blooms.

Clinging to the stem of a Yellow bells (Tacoma stans) while surrounded by Giant spiderwort (Tradescantia gigantea).

This one poised to flutter to the bog area of my pond, which is a favorite bathing spot for all the birds in the garden, residents and visitors alike.

Jump!

If you look closely at the following photos, you can spot the smudge of orange, which male Orange-crowns flash in territorial warning when necessary, but which is drab and undramatic when life is simple and there are no threats to manhood, or perhaps I should say, birdhood.

 

I still see Yellow-rumped Warblers, Setophaga coronata, like these two breeding-plumaged boys, preparing for a buddy bath.

The photo isn’t the best, taken early and pre-coffee and through a window, but I was tickled to catch them hanging around. Do you see the difference between the two?

You’ll notice that the one toward the bottom has a yellow throat–he’s an Audubon’s subspecies and typically found in the West.  The other with a white throat, is a Myrtle subspecies and they’re more common in the eastern part of the United States and in Canada.  I have no clue why both were in my back garden, but it was a treat to see and photograph both in the same frame. More proof I suppose that Texas truly is a crossroads for migratory birds.

Too bad those blackberries aren’t ripe.

Butter Butts have been constant companions since November, but will soon be gone, making their way north to the upper mid-West and Canada for summer,  My early mornings won’t be the same without them.

 

One of the last winter Texans to leave for northern lands are the Cedar Waxwings,   Bombycilla cedrorum.  Such beautiful birds, they’re always in a flock, gabbing and preening, and usually situated at the top of trees, where it’s too blustery to get a good photo. Even if I managed something decent, it would be of their butts and who wants to see that?   I was on the phone with a friend when a couple of them dropped in to bathe and drink in the birdbath with the bubbling fountain. I told my friend that I HAD to hang up NOW so I could get some good, close shots of these dandies and she was gracious enough to let me go, forthwith.  She’s understanding about my various idiosyncrasies and I knew she wouldn’t be offended at my hasty hangup.

As I write, I hear their high-pitched keening in the breezes outside, their voices carried into the house, keeping me company.  Soon enough,  that keening will no longer linger in the breeze and will be silent; I’ll realize that they’re gone for summer.

I miss them already.

One day next November, I’ll hear their call again–high-pitched and insistent. I’ll be thrilled that they’ve once again joined me for winter and much of spring.

 

I take pleasure in the typical off-and-on visits from Lesser Goldfinches,                     Spinus psaltria, but they’ve been scarce this year.  I have delighted in several visits from a little band of American GoldfinchesSpinus tristis.  

Mostly, they’ve frequented the birdbaths,

First you see my front,

….then you see my back.

…the bog of the pond,

…or perched prettily in the shrubs and trees.

Until I downloaded this photo, I didn’t realize that there were two other goldfinches at the right edge of the above photo.  Like the Cedar Waxwings and teenage humans, Goldfinches tend to hang out in groups, though they’re quieter than the Waxwings–and the human teenagers.

If you’re fortunate enough to host these birds during their summer breeding, they will nosh at feeders, but prefer native composite (Asteraceae) seeds; flower seeds of the many varieties of sunflowers are finch (of all species) favorites.  The trick for attracting Goldfinches, as well as many other native songbirds, is to let the seeds develop after the bloom period.  Many gardeners want to prune back “spent” blooms because there’s nothing left  for pollinators and we’ve been “educated” that spent blooms are unattractive.  Nothing could be further from the truth.  Flower seed heads are attractive and the second round of feeding on a plant comes after the bloom-n-pollination/nectar gathering time: it’s the feeding time for birds, mammals and other insects besides pollinators.  When you see a host of birds eating seeds at plants, it’s a lovely and affirming sight and that nourishing of wildlife is the purpose of plants.

While the migratory birds are movin’ on to their summer breeding sites, I’m left with my resident birds, like this bathing male Northern CardinalCardinalis cardinalis.

Well, that’s not so bad.

 

Blue orchard beesOsmia lignaria, are almost finished with their seasonal contribution to the world and my garden.

The few remaining adults left are packing away their eggs and soon-to-be-larvae. There are plenty blue bee babies cookin’ for next year.

 

My favorite native bees, the Horsefly-like Carpenter bee,  Xylocopa tabaniformis, are out in droves and pollinating up a flower-storm!

Stealing nectar from an Autumn sage (Salvia greggii).

More nectar at a Gulf penstemon (Penstemon tenuis).

Zoom!

Got it!

Uh, the pollen and nectar of the white Autumn sage are the other way…

 

Ubiquitous Texan Crescent butterflies, Anthanassa texana, are also making the rounds of blooming bounty.

 

This Pipevine SwallowtailBattus philenor, is battered–but not defeated–in its quest for nutrients from flowers of the Giant spiderwort.  There will be more of these gorgeous and useful insects in my gardens in coming months.

He may display rag-tag wings, but he works the garden diligently and for free!
