Three Bees Pollinating

Spring sprung many months ago, summer’s hardy floral gifts, amidst Texas heat and drought, delivered color and life with attending pollinator action throughout those toasty months. Summer is finally done and autumn is a robust flowering period, full of blooming goodness. A pollinator frenzy is in full swing in my Austin garden.

The yellows, especially Plateau Goldeneye, Viguiera dentata, are the pollinators’ delight. Monarchs have mostly drifted southward along gusts delivered by the last cold front. Other butterflies seem to be on vacation, but bees are still around and about–and pollinating. Most folks know about honeybees, but native or wild bees, are common and vital in any healthy ecosystem, whether in a natural green space or a planned and loved garden. In a recent stroll through my garden, I observed multiples of three kinds of bees that were all-in with their pollination business, sharing flower space they buzzed about a Plateau Goldeneye.

Here, a honeybee works the flower, her little leg splayed out, maybe for balance or perhaps preparing to scoot over to the next flower. A bee’s version of getting a leg up?

The same bee on the same flower, all hunched up and nectaring away!

This bee isn’t a honey, but a native, or wild, bee. My best guess, utilizing this website hosted by an entomologist at The University of Texas whose research focuses on native bees, is that this little gal belongs to the leafcutter bee family.

I like this bird’s-eye view of the leafcutter bee, pollen pantaloons (aka, corbiculae) full-to-bursting with a packed load of beautiful, golden pollen.

The third bee sort zipping around was this tiny thing, most likely a native sweat bee. All native bees are efficient pollinators, regardless of size, though size dictates how much nectar is consumed and the amount of pollen that is gathered. This little one won’t sip as much nectar or pack as much pollen as her bumble relatives, but she and her sisters are excellent in their important work.

This shot captures the difference in size between the sweat and the honey bee. Both are focused on their respective flowers.

Some bees are generalists, visiting a variety of flowers, others are more particular, arriving when certain flowers are in bloom, absent from the garden when that plant is in a resting stage. How the bee knows when its favored bloom is ready for pollination is a mystery, at least to me. Entomologists understand much about honeybees, but there’s comparatively little research on native bees. There are roughly 20,000 native bee species in the world, about 4000 reside in North America, and 350 in Texas. In fact, a new bee was recently discovered and named, existing only in Texas and Oklahoma: the Andrena androfovea–a blue bee, which you can read about here. This blue bee is one of those bees that sips from only one species of plant!

I’ve “identified” roughly 15-18 native in my garden over the years. I don’t necessarily know the name of each (though I know some), as there’s not much information available, so I look at photos and make guesses. Lots of guesses. But I have learned to recognize a bumble from a carpenter, a sweat from a leafcutter, a metallic from a bee mimic. I’ve become familiar with their habits: some are wood nesters, others nest in the ground, most (except for honeybees) are solitary and make small amounts of honey to feed their offspring. I recognize the leaf ‘damage’ that bees do to certain plants in my garden, as they pack their nesting sites with leaf matter, mud, and pollen. Some native bees forage for a brief time in early spring , lay their eggs in protected wood or plant stems, then die. Others are around throughout the growing season, procreating and nectaring all the while.

Native plants and native wildlife, insects included, evolved together and need each other to survive. A vibrant ecosystem will support this symbiotic relationship which defines the life cycles and relationships of flora and fauna. Go native and watch your garden and its inhabitants bloom with life and activity!

Bees A’buzz

It was a slow start to the carpenter and bumble bee action this year, I assume because of the heavy rains experienced in Central Texas in May and June/early July. But recently the garden is a’buzz with honeybees and a variety of native bees, including the big, noisy carpenter and bumble bees.

This Horsefly-like Carpenter bee, Xylocopa tabaniformis, worked the prolific blooms of a Flame Acanthus, Anisacanthus quadrifidus, in my front garden.

These charming bees are probably my favorite bees. They’re noisy and buzzy, darling in looks. I love their racing stripes and melt at their dreamy blue eyes.

I like this up-side-down visage: bee-butt up pointed upward, proboscis-leading snout concentrated on the liquid deep in the tubular nectar fonts where the bee’s proboscis is headed.

Nectar stealing or nectar robbing is when an insect pokes or bites a hole in flowers that are too deep or small for the insect to enter from the open bloom. The insect then sips nectar without entering the flower’s innards, bypassing direct pollination.

Ole Blue Eyes here is just about to deliver its pointy proboscis, aiming for the fleshy, thin petal and the sweet stuff inside. The bee sliced the petal with its formidable mandibles to gain entry.

Bum-up view of the nectar-stealing, nectar-sipping bee. While direct pollination isn’t happening, you’ll notice grains of pollen sprinkled on Ole Blue Eyes’ body. It’s likely that some of those grains will play a role in pollination.

The other bees I’m seeing more of–and a big Huzzah! for that–are American Bumble bees, Bombus pensylvanicus. These graceful, yellow-n-black sweethearts are working many kinds of flowers right now, but a favorite bumble dining spot are the blue blooms of Henry Duelberg Sage, Salvia farinacea, ‘Henry Duelberg’. Notice the pollen booty on this bee’s pollen pantaloon, also known as a corbicula. If you look carefully, you can see a dab of golden on the other side of the bee–no doubt that pantaloon also carries a load of pollen.

My garden always enjoys more insect action, especially of the pollinator kind, as the growing season progresses. Heavy rains in spring and early summer often damage ground and wood nesters, so their procreation is slowed. Those insects rally as summer heats up and stable weather patterns settle in. In a healthy, diverse garden community, the pollinators persevere, the garden flourishes, and the gardener gives thanks.

Bathing Cutey

I initially planned to title this post ‘Bathing Beauty’ but realized that title was boring and obvious, and didn’t adequately describe the bird images I wanted to use. I mean, look at this silly goober.

The juvenile Northern Mockingbird, Mimus polyglottos, will become a beauty when older and dryer, but for this particular moment in time, in its wet-n-wild state, it’s a goofy, floofy, cutey bird.

The young Mockingbird, as well as a couple of its elders, have spent time in the back garden recently. Typically, I don’t see many mocks in my back garden, the exception to that observation being during native plant berry season, which has arrived.

American Beauty Berry, Callicarpa americana, is getting its purple on with each passing day. You might notice that not all the berries have gotten the message to change their hues, but enough of the clusters are trading their green for the outrageous purple of maturity and birds have noticed–and noshed.

My two Roughleaf Dogwood trees, Cornus drummondii, also sport berries, though their signature ripe color, creamy white, hasn’t yet appeared. That lack of color change, with its indication of full ready-to-eat ripeness, isn’t stopping the Mockingbirds, European Starlings, or Blue Jays from plucking and gulping, as I’ve observed all three species feeding on the green berries. I guess it’s similar to my eating a peach that isn’t quite ripe, still a little hard, but so delicious that I just can’t help myself.

I hope these resident birds will leave a few fruits for the migratory birds, but there’s probably enough for all who are interested. Besides, the Possumhaw and Yaupon Hollies will be adding their fruit selections to the garden menu in the not-too-distant future.

So bathe away, cutey Mockingbird–and make sure to get your share of the garden snacks!
