Rough-leaved Goldenrod and Black Locust Borer

Print Friendly

The Rough-leaved Goldenrod (Solidago rugosa) has been the most popular plant in the backyard recently. The airy, arching stems with yellow blossoms have been a gathering place for a myriad of insects including bees, flies, wasps, and unknowns, all busily feeding on nectar and gathering pollen.

This is one of the insects that got my attention (click images for larger versions).

I checked BugGuide and discovered it’s a Black Locust Borer (Megacyllene robiniae). Adults feed on pollen, particularly from goldenrods. The larvae live on Black Locust trees and can be a pest.

When I cropped an image to get this close-up, I was surprised to see that the body was somewhat fuzzy.

I enjoyed observing all the comings and goings on this goldenrod plant, and I’ve decided watching insects is great fun. There were far too many interesting creatures for one blog and I’ll share more images later.

  1. I also am amazed at the various insects that appear on a new plant I have added to my garden – “showy goldenrod” being one.

    Always enjoy your blogs. I see your email and instantly wonder….what has Betty found now ; )

    1. Christine, glad to hear that you are seeing lots of action on your Showy Goldenrod. The action was on my “Showy” two weeks ago – and as it passed its peak, the “Rough-leaved” began to bloom, and the scene changed. It’s obvious the insects know more about pollen and nectar than I do! Exploring the backyard and sharing with others is great fun. I appreciate knowing you share my interests and always glad to hear what’s going on there.

  2. Beautiful detail on that little guy. Can’t beat that pop of yellow. Showy goldenrod is definitely living up to its name this year. I am seeing it everywhere! You should visit the retaining pond near the Tates Creek Library. I saw mistflower and goldenrod and so many other native plants. Looks beautiful right now!
