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).
