Goldenrod Pollen

9-4-13 goldenrod pollen 305Goldenrod is an extremely important foraging plant for honeybees in the late summer, when its flowers produce prolific amounts of nectar and protein-rich pollen. Goldenrod pollen, the orange lump that you see packed into the pollen basket (after being mixed with saliva) on the hind leg of this honeybee, is often blamed for the allergies that many people experience in the late summer and early fall. It is falsely accused, however, as ragweed pollen is the real culprit. Being wind pollinated, ragweed has light, fluffy pollen, which is easily dispersed (and easily enters nostrils). Goldenrod pollen is large and sticky, allowing visiting insects to gather it (intentionally as well as unintentionally) all over their bodies and transfer it to other goldenrod flowers, therein cross-pollinating them.

Goldenrod Visitors

If you want to get an idea of the number and variety of wasps, bees, beetles and bugs that reside in your area, go to the nearest goldenrod patch sit for a spell – this member of the Aster family is a magnet for insects. You’ll find many foliage- eating bugs and beetles, leaf-mining  larvae, nectar and pollen feeders, and flower and seed-eaters.  In addition, many predatory spiders (jumping and crab, especially) and insects (ambush bugs, ladybug beetles, flower bugs etc.) have discovered that goldenrod  is a goldmine for them, as well. Researchers have found nearly 250 species of insects feeding on one species of goldenrod (Solidago canadensis).   Pictured from left to right are a long-horned beetle (locust borer, Megacyllene robiniae  – pollen eater), a fly (nectar feeder) and bee (nectar and pollen feeder).
