Maximum Sunflower Power

 Ladies and Gentlemen, boys and girls, dogs and bees, I give you the crowning glory of the Kansas fall prairie, the Maximilian Sunflower (Helianthus maximiliani).   On the prairie near me right now, one can see lots of yellow flowers blooming, foremost being the light-yellow green of the native goldenrods, but nothing outshines or is taller than the Maximilian sunflowers.   Standing out hundreds of feet away, each clump betrays the location of a site of disturbed earth, the sunflower a sure marker of soil chaos.   Bees and humans alike are drawn to it, the screaming color calling across the ocean of drying prairie grasses.

This clump came up near my burn pile.   There's a smaller group in the middle of the unmown area of the back yard (my so-called "rain garden"), but it is this plant at the back edge of the garden that begs for attention.  And, as you can see above, it got attention from this very busy bee photobombing the flower.  It also got attention from Mrs. ProfessorRoush, who posed with it for me, but I will not share the beauty of the former in this blog, Internet privacy and all being what it is.  I found it interesting that the sunflower and Mrs. ProfessorRoush are almost identical in height, 5 feet tall or so.

The bumblebee that attacked these members of the Aster family was fortuitous for my camera, arriving just as I moved in to photograph the flower closely.  In a month these flowers will be bountiful seedheads, full of energy and a good forage crop for livestock and deer.  

You can see here what I mean about the goldenrod.  I'm not good enough at quick identification to tell you if this is Prairie Goldenrod or Canada Goldenrod or another species, but this is as yellow as it gets and the brightness fades quickly like the plants in the background here.  

Between the bad press given to goldenrod, and the happy beaming face of the Maximilian Sunflower, I've got to choose the sunflower every time.   And so, it seems do the bees.  The only insect I've ever seen on goldenrod around here are the goldenrod soldier beetles.

Gardens of Caligula

This week my garden has been transformed into a den of inequity.

A couple of days past, I was peacefully walking through my garden, virtuous and wholesomely thinking only of the graceful lines of mature ornamental grasses and cherubic cement angels.  Suddenly, I stumbled across a garden orgy sufficient to satisfy Caligula.  Fornication!  Out in the open and here among the flowers!  What kind of brothel am I running?

I have a line of 'Matrona' sedum lining one of my beds, and on the flowers of those sedums were a writhing, panting mass of  Goldenrod Soldier Beetles (Chauliognathus pensylvanicus), most of them in flagrante delicto and completely unaware of my voyeurism.  I had an immediate flashback to a time over a decade ago when I was in Vancouver, Canada at a teaching seminar, exploring the famous Wreck Beach on my spare time, only to find out that the Wreck Beach was famous primarily for its clothing-optional section.  At least the insects on my 'Matrona' weren't playing nude volleyball, an image still seared on my eyeballs now some 15 years later.  One internet source noted that the insects mate "for extended periods on the flowers" although "the reason for their lengthy mating period is not certain."  The source did note that females in the act of mating are less likely to be disturbed by wasps than single females.  To that observation, I say "duh", because by my careful observation, what I presume is the male partner is always on top, his back exposed to the wasp, while the female hides protected underneath.

If these beetles were looking for goldenrod, their favorite food source, to homestead on, they are a little early in my garden, for most of the goldenrod hasn't bloomed yet.  Perhaps they are just getting the essential act of procreation out of the way before gorging themselves and fattening for winter, not unlike other species that periodically visit my garden. More likely, they are just the insect equivalent of pubescent humans, driven into ill-considered acts by overactive glands. The next thing you know, they'll be riding giant insect roller coasters just to impress pretty girls (ask me about that story sometime...). 

Goldenrod Soldier Beetles, also known as Pennsylvania leatherwings, are believed to be completely harmless to the flowers and in fact may participate in pollination.  Their larvae are also predators of aphids and other soft-bellied insects.  Several sources tell me the adult beetles secrete an anti-feedant, Z-dihydromatricaria acid, from 9 gland pairs on their abdomens, a defensive move to keep predatory jumping spiders away.   Their presence in this bed of my roses is thus a positive occurrence and instead of being shocked, I should welcome and encourage all the intercourse that they want to have.  I have concluded, therefore, that my best action is to allow them to continue their wanton behavior, averting my eyes from details of the promiscuous activity all around me with the tolerance of a saint among sinners.
