Picture this during National Pollinator Week: five monarch caterpillars and assorted honey bees sharing tropical milkweed.
It was love at first bite. Or love at first sip.
The 'cats kept munching and the bees kept foraging. Neither species seemed interested in the other.
But the adult monarchs definitely showed more interest in the tropical milkweed (Asclepias curassavica), a non-native, than the other two species, both natives, that we planted: the narrow leaf (A. fascicularis) and showy milkweed (A. speciosa).
They laid eggs only on the tropical milkweed, and so far, have produced five caterpillars.
The score to date:
Tropical milkweed: 5 caterpillars
Narrow leaf milkweed: 0
Showy milkweed: 0
Reminder: Folks planting the tropical milkweed in temperate zones (like here in Vacaville,Calif.) must remove or cut back the tropical milkweed by winter. "A protozoan parasite of monarch butterflies, Ophryocystis elektroscirrha or OE for short, can travel with monarchs visiting the plants and become deposited on leaves," explains the Xerces Society for Invertebrate Conservation.
Yes, indeed. But meanwhile, we're witnessing untold sharing on the wildly popular tropical milkweed by not only monarch caterpillars but honey bees, syrphid flies, bumble bees, carpenter bees, leafcutter bees and sweat bees.
We gardeners and photographers are also drawn to the spectacular red, orange and yellow flowers that add both beauty and color to a cherished pollinator patch in the midst of the COVID-19 pandemic...and National Pollinator Week.
You can't get any more Halloween than a bold (daring) jumping spider with orange spots!
This common North American spider was hanging out yesterday on our showy milkweed, Asclepias speciosa, trying to look like a spectator instead of a predator.
The orange spots indicate it's a juvenile Phidippus audax. As it matures, those spots will turn white. It can jump 10 to 15 times its body length, deploying its silk "lifeline" when it's jumping for prey or evading predators, according to Wikipedia. It hunts only in the daytime.
Yesterday, resplendent in its iridescent chelicerae (mouthparts or "fangs"), the eight-eyed, eight-legged dark hairy spider crawled around the broad leaves of the milkweed, sharing its home with assorted lady beetles, aphids, wasps and an occasional butterfly (Monarchs, Gulf Fritillaries and skippers).
It soaked up some sun and then apparently decided that the telephoto camera lens represented a clear and present danger, too bold and too daring.
A little haggard, a little worn, a little ragged, a little torn.
But there she was on Monday, Aug. 1, the first monarch of the season to lay eggs in our little pollinator garden in Vacaville, Calif.
She found the milkweed, but that was AFTER the aphids, milkweed bugs, praying mantids, assassin bugs and assorted spiders claimed it.
It's always a joy to see the majestic monarch fluttering through a pollinator garden. On Sunday, July 31, a male lingered for two hours, nectaring on the Mexican sunflower (Tithonia) as the male territorial longhorn bees tried to chase him away. No welcome mat for him! No place setting for him!
Then today, a female arrived, first stopping by the showy milkweed, Asclepias speciosa, to lay eggs and then fluttering over to the tropical milkweed, Asclepias curassavica, to lay more.
It's amazing how the monarchs, Danaus plexippus, know how to put their "resources" in multiple places. Like the idiom that cautions "don't put all your eggs in one basket," instinctively they seem to know that if they put all their resources in one place, they could lose them all. There's a better chance of offspring survival if they spread the eggs around.
In real life, insects "get" milkweed.
We all know it's the only host plant of the monarch butterfly--where monarchs lay their eggs--but it's also a a great source of nectar for butterflies and other insects.
Take the showy milkweed, Asclepias speciosa. Native to California, it is found throughout North America, including in our little pollinator garden!
Speciosa nectar is sweet, tantalizing and irresistible.
Recently we've been watching the diversity of insects gathering on our milkweed. Sometimes it's a pushing/shoving match or I'll-fly-away-but-I'll-be-back-as-soon-as-you-leave vow.
Have you ever seen a male Valley carpenter bee, Xylocopa varipuncta, nectaring on milkweed? The male, a green-eyed blond about the size of a queen bumble bee, can't sting. Or as native pollinator specialist Robbin Thorp, distinguished emeritus professor of entomology at UC Davis says--"Boy bees can't sting." He calls it "the teddy bear bee." What could be more cuddly than this little fellow?
So here's this teddy bear bee trying to grab some nectar while honey bees are buzzing around him trying to get their share. He's bigger; they're louder.
And then, the female of this Valley carpenter bee species (she's solid black--the two represent a clear case of sexual dimorphism) comes along and the bees scatter. Our boy bee does, too.
The bees will be back. The nectar is sweet, tantalizing and irresistible.
There's an old saying applicable to child-rearing: "First you give them roots, and then you give them wings."
Roots to ground them, to love them unconditionally. And wings for them to lift off and launch new beginnings.
Quote Investigator attributes the origin to newspaper editor Hodding Carter's book, "Where Main Street Meets the River," published in 1953. Carter credited a "wise woman" with saying that:
"A wise woman once said to me that there are only two lasting bequests we can hope to give our children. One of these she said is roots, the other, wings. And they can only be grown, these roots and these wings, in the home..."
But have you ever walked through a pollinator garden and been awestuck by the beauty of wings? The iridescence wings of a female Valley carpenter bee, Xylocopa varipuncta?
It was Sunday, May 21 and the feeding frenzy on our showy milkweed, Asclepias speciosa, was in full swing: it was a pushing, shoving and sipping match for the honey bees, carpenter bees, sweat bees, lady beetles, and syrphid flies.
But it was the wings--and wing venation--of a carpenter bee sparkling in the sunlight that caught our attention.
The wing venation "clearly shows a couple of characteristic features of Xylocopa wing venation: the long slender marginal cell and the 'boot-shaped'" second submarginal ('toe' pointing toward head end)," noted native pollinator specialist Robbin Thorp, distinguished emeritus professor of entomology at the University of California, Davis, and co-author of California Bees and Blooms: A Guide for Gardeners and Naturalists.
Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology, also weighed in. "They are lovely. Not too many wasps or bees wings have this iridescence. That's an old lady by the way. Look how worn her wings are."
The LOL loved the showy milkweed. But she's the one that put on the show.
