Aster (Asteraceae)

Rigid Goldenrod

Solidago rigida L.

This plant is visited by at least forty species of insects in late summer and fall. Butterflies, bees and flies all visit the dense flowering heads of this Goldenrod. Since it provides nectar to so many insects, Rigid Goldenrod is one of the most important grassland plants. It receives so many visitors that highly camouflaged ambush bugs hide on the flowers, and capture and eat the plants’ pollinators.
