Symplocarpus foetidus

     


     
     The earliest spring wildflower to emerge from dormancy is skunk cabbage (Symplocarpus foetidus). In fact, this species flowers so early, it could be considered a winter wildflower! Skunk cabbage flowers have the ability to heat up the surrounding snow, which promotes melting so it can poke its fragrant flowers up through the ground. 
     Skunk cabbage has unusual flowers, like all members of the Arum family (Araceae). They consist of a spathe, an outer sheath which surrounds the inflorescence, and a spadix, a fleshy stem on which tiny flowers are produced.
     

Newly emerging leaves
     Many plants that produce flowers at the surface of the ground are brown in color and stink like decaying organic matter. This is to attract pollinators, typically flies, but this also lures in beetles and ants as well. Pollinators are also attracted to the flowers because of the heat they produce which leads to another interesting evolutionary strategy.
     Why flower so early? On the one hand, there are not many pollinators available in the early spring because it is too cold for them to be active or present. However, the few insects that are active and present are looking for food and warmth. The skunk cabbage receives virtually exclusive attention because it flowers when nothing else is available.
     “Symplocarpus” is Greek for “connected fruits” and “foetidus” translates from Latin to “malodorous” meaning “smelling very unpleasant.” From this, the term “fetid” derives.

     These photos were taken in a forest preserve in Cook County on March 18, 2016.  There is a healthy population at this location.

Floating Corn

I witnessed a small phenomenon today
something floating in the sky.
It was somehow fluttering
and gracefully falling.

A huge highway lined on both sides
by a thin strip of brown.
The chicory, mustards, the sweet clovers,
and those damned yellow composites,
brought to end by the mower blade
and left to bake in the sun.

Solidago in a bloom of yellow love
speaks of late September.
Puffy clouds dot the azure sky,
corn abounds, but not yet harvested,
singing along to Bob Seger on the radio.

The scene is set so that you may appreciate,
my glory and delight,
when I saw that strange sight,
half a cornstalk sheath,
hovering,
then slowly descending,
behind the bridge.

Beech Blight Aphids

     On the most recent Wildflower Walk at Bell Smith Springs we stumbled upon a furry white insect on the twigs of a beech tree, with a few spilling over on the leaves.  I refer to them as boogie woogie bugs, but they are more commonly known as beech blight aphids (Grylloprociphilus imbricator). Whatever you call them, these aphids are a species of true bugs. belonging to the order Hemiptera and the family Aphididae.
Beech Blight Aphids (Grylloprociphilus imbricator)
     The white waxy filaments are secreted by the aphids and make them unappealing to prey.  They wave their bodies around, fanning the cotton-like tufts when they are disturbed, reminding predators not to bother them.  These fascinating insects feed on the sap of the beech trees, but do not cause any major lasting damage to them.  The aphids are particularly interested in the protein contained in the plant sap.  Yet most of the plant sap is water and carbohydrates, basically sugary water, As they pierce the branch with their specialized mouthparts, the high pressure of the liquid in the vascular tissue causes sap to shoot out of the tree and into the insect, in this case, the aphid.  This causes the previously ingested watery, sugary sap to shoot quickly through the digestive tract and out of the body of the aphid.  The resulting liquid is called honeydew, or one could think of it as aphid excrement.
     Nature has a way of letting nothing go to waste.  One organism's waste is another's treasure.  And such it is with the aphid poop.  It attracts a black mold called the beech blight sooty mold (Scolias spongiosa).  This mold is a specialist, as it only grows on the honeydew of the beech blight aphid.  This species of aphid likes to congregate, which concentrates the honeydew.  This is why the black sooty mold grows in large clumps, versus other black mold, which is restricted to just a light layer on the leaves because of solitary aphid species.   
     Yet another example of how nature is amazing.  Watch a short video here.

Chigger Poem

Oh why oh why do there have to be chiggers
for a reaction in me they sure do trigger
The many little red bites feel like Braille
And when they itch they make me want to wail!

If you like evolution, then you must love the chigger
For they would not be as bad if they happened to be bigger
But an invisible invertebrate has all the advantage
And leaves me with little else than to put on a bandage.

I guess I could prevent them by staying on the trail
Or if I took more time to scratch them with my nail
I could spray myself with nasty chemicals and deet
Or stay inside all together and beat the summer heat!

But that is not my style, I was born to explore
To see the nature and learn from it more
Plus if there were less chiggers there’d be more tourists
And it would be impossible to be a nature purist.
