Ranger Steve’s Nature Niche: Gold Treasures

The field has turned to gold overnight. The rich value exceeds that of the precious metal many would trade several weeks’ pay to possess. The field transforms itself without the aid of a forger pounding and engraving to human desire. The field knows just what a person needs to lift one’s spirits and hopes.

Unlike the metal artisan that makes permanent engravings, the field has ever changing beauty that entices us to search its gold flower settings. Its golden surface has creative intricacies of a jewelry artist’s dreams.

After weeks of drought when plants seemed frozen in time, a 6-inch rain soaked deep. Plants greedily took every drop possible to quench a long waiting thirst. Less than half of the goldenrod were in bloom yesterday even though it was past normal flowering season. Today more than 70% are blooming. The waiting burst of gold was not just by plants. Insects of great variety have been on hold in quest of the rich golden treasure.

Goldenrod’s flowers and pollen are more essential to life than a person’s quest for gold at the end of the rainbow. Like people seeking a pot of gold at rainbows end, insects seek the ephemeral gold of late summer. Many have their nature niche lives timed to its flowering. Bees and other insects seek nectar. The nectar reward is not free. Insects leave with a full stomach but are loaded with pollen they carry to neighboring goldenrods.

Goldenrod pollen is large and heavy. It does not blow distances in the wind and requires delivery service to transport it to mature flowers. When a golden finch lands on a goldenrod stem in search of a tasty insect morsel, it undoubtedly knocks loose pollen. Instead of easily drifting on air currents to another flower, it falls to the ground. A number of ground creeping invertebrates consume the manna falling from the heavens.

Pollen eating insects are attracted to the flowers like people are attracted to all you can eat restaurants. Goldenrods like other members of the large aster family, produce in excess to make sure pollen grains fertilize other flowers. Insects at the smorgasbord leave with pollen covered bodies to serve as dispersal agents.

I was told by a honeybee keeper, that members of his profession do not appreciate gold season. Honey bees get rich feeding on goldenrod nectar but the honey produced is bitter. People desire sweeter honey.

The value of gold is in the eye of the beholder. Bees are joyous with the concentrated fields of gold. Honey connoisseurs are dismayed. I am particularly pleased with the great variety of creatures found among goldenrod. The abundance of monarchs deep golden orange in fields brings happiness to many. Pearl Crescents stand still on flowerheads long enough for us to see the tiny silver pearl adorning the hindwing undersurface at its tail end. The pearl is surrounded by the butterfly’s own version of muted gold.

One can walk through a field of gold and return home with more golden memories than are possible to retain. It is necessary to share as many as possible at the dinner table before they are lost like nighttime dreams that seem to vaporize by the time breakfast is finished.

Soldier beetles with gold and black wings find the massive flower heads perfect beds for copulation. Net-winged beetles with their own version of gold and black wing elytra are differently shaped, with the tail end of wings widening to give a triangular appearance.

It is always good to have a field guide at the ready. Many find cell phone photos useful. Increasingly Apps are able to narrow an identification search to a few likely insects similar to how facial recognition programs are being used. For those of us still more comfortable with paper field guides, we flip pages in books like the Golden Guide to Insects. The Golden Guide is still our version of gold treasure at the end of a rainbow.
