Restoring Bottomland Prairie: Pollinators on Flowering Shrubs, March-April 2017

In 1999, we put in a riparian buffer along McDowell Creek.  We planted over a thousand bare-root seedlings that were part of the "wildlife bundle" we purchased from KSU's Forestry Department.   The flowering shrubs featured below--American Plums, Fragrant Sumac, and Chokecherries--were in that bundle.  But the same species also volunteer along the creek.  Over time the two groups have merged with each other as the banks and channels have changed and both creek and bottomground have rewritten themselves.

This year it came home to me how important these early-blooming shrubs are to pollinators.   What did the bottomground look like pre-settlement?  I don't know, but today these shrubs are an essential early-spring sweet spot for butterflies, flies, and bees.

Right at the Equinox the wild plums bloomed.  They sent the most delicate fragrance out onto the breeze--and the pollinators responded by moving toward them.  

They weren't the only ones! I pulled a lawn chair into a thicket and just sat for a few moments.  The blossoms were alive with Red Admiral butterflies, feral Honey Bees, and flies.  

The video above shows some of what I saw.  How I wish it could convey what I heard, and felt, and smelled as well--the rustling, the breeze, the fragrances, the fresh spring air...

as flowers.

A month later, the Fragrant Sumac bloomed.   So many butterflies!  The shrubs seemed to be blooming with butterflies, as well as with flowers.


The luscious yellow blossoms were covered with butterflies, as shown in the video below.  Most of the butterflies were Painted Ladies (Vanessa cardui) and American Ladies (Vanessa virginiensis), though two beautiful Common Buckeyes (Junonia coenia) also made an appearance, as well as an Eastern Tailed Blue.

Also appearing was a species of bee new to Bird Runner, or at least to my observations on Bird Runner.  It was a Mining Bee (genus Andrena).  Bees in the family Andrenidae nectar on early-blooming shrubs and gather pollen to provision their nests.  True to their name, they burrow in the ground, creating as many as 8 cells per burrow, with a pollen ball in each cell.  That's where they lay their eggs--one egg on each ball.   The newly hatched larvae eat the pollen until it's time to pupate.

The Chokecherries bloomed at the same time as the Fragrant Sumac.  In the video below a Question Mark butterfly appears first, followed by a Painted Lady, then the Question Mark again, followed by an American Lady.  The final scene shows an American Lady in the foreground with a Question Mark in the background.  



Flowering shrubs, you are amazing!   Where do you stop and the insects around you begin?   You have roots, leaves, stems, branches, and flowers, but you also have all around you an aura of fluttering, special markings, and color.
