Here in Mississippi we’re in the midst of the oppressive heat of August.
I’m not complaining. It’s just a fact of life.
But still – it’s August… in Mississippi…
Unless I stay indoors with the ac cranked, there is not much relief.
I can take a soak in the cold tub and dream of Paradise Falls for a while. But… you can’t stay in the tub all day.
So I do all my gardening early while it’s still a little cool. Then I opt for a cruise in the golf cart from one patch of shade to the next.
I pause at the Bee Meadow and watch the honeybees fan themselves on the “front porches” of their hives. Then I linger to study the flowers.
This is the season of yellow daisies. Sweet coneflower (Rudbeckia subtomentosa), orange black eyed Susan (Rudbeckia fulgida var. fulgida) and starry rosinweed (Silphium asteriscus) offer their golden blossoms to the sun. The grasses (switch, big blue, Indian and Eastern gamma) are their stalwart companions. The heat does not discourage these robust beauties.
But looking at all those warm orange and yellow blooms seems to make more sweat trickle down the back of my neck. And looking at the grasses makes me itch.
Whiteleaf mountain mint and switch grass grace the Bee Meadow in August.
I am refreshed a bit though when I set my eyes on the frosty bracts of the mountain mint that is blooming now.
Whiteleaf mountain mint (Pycnanthemum albescens) is among the last native mints to bloom here. In July tiny purple spotted flowers make their appearance surrounded at first by white edged leafy bracts. By August the first frost comes and the entire bract turns hoary white.
Here's my best attempt to capture mountain mint's frosty white bracts.
I am not the only one who is drawn to the mountain mint. A steady stream of pollinators visits the flowers. At every viewing, I usually see at least four or five kinds of native bees and flies. When I lean in close to study an unknown pollinator the mountain mint releases a heady mint scent into the air. Ahhh!
Last weekend I managed to identify an unknown pollinator that has intrigued me for over a decade. The first time I saw this bee relative, I described it as an iridescent purple dirt dauber. I’ve seen it regularly over the years but only when the mountain mint is in bloom.
So… I set out to solve the mystery and after a wasted hour (in the ac) on the computer, I determined that the mystery pollinator was a giant black wasp. This is a gentle ground nesting wasp. Usually the males visit the flowers and they cannot sting me because they have no ovipositor.
The giant black wasp is busy foraging on refreshing mountain mint nectar.
The females are far too busy to sting because they are hunting, stinging and carrying paralyzed katydids back to the nest to feed the youngsters.
The giant black wasp has a slender thread-like waist. It is commonly close to 2 inches long. In certain light it appears to be black but soon the sun illuminates metallic purple pigments. It is quite striking.
So for a few moments I forget that the heat is hanging heavily around me and that the humid air is almost too liquid to breathe. I am transfixed – I watch the giant black wasps forage. I make note of the tiny sweat bees, the flower fly and a mysterious pollinating fly. All of them are headed for the frosty bracts and minty nectar of the whiteleaf mountain mint.
I look past them all – hoping to see a giant black wasp mama flying toward her nest burdened by a stupified katydid.
I have not seen her yet.
But… there is still tomorrow!
