Description
 
 

Goldenrod soldier beetle is the most common soldier beetle in the Midwest. It is considered beneficial because its larvae feed on the striped cucumber beetle and other pests.

Adults are to 9 16 long and colorful. The body is elongated, soft, and somewhat flattened. The sides are nearly parallel. The underside is black.

The thoracic shield (pronotum) is wider than long and brownish-yellow or orangish-yellow. A black spot covers most of the back (posterior) three quarters of the pronotum. The spot is widest at the front (anterior) and does not extend to the anterior margin of the pronotum.

The abdominal segments are mostly black with a narrow brownish-yellow or orangish-yellow posterior margin. The forewings (elytra) are brownish-yellow or orangish-yellow and loose. They are leathery and flexible, not hardened like on most beetles. They are long but do not extend beyond the abdomen. Each elytron has a black, elongated, longitudinal mark. The black mark is usually confined to the posterior half but sometimes extends the entire length of the elytron. The inner (sutural) and outer (lateral) margins are always brownish-yellow or orangish-yellow.

The head is black, large, and prominent. It is visible from above, not concealed beneath the pronotum. The antennae are slender, thread-like, black, and more than half as long as the body.

The legs are long, and slender, and mostly black. The third and most robust segment of each leg (femur) is entirely black. The fourth segment (tibia) of the front leg is brownish-yellow or orangish-yellow. The end segment of each leg (tarsus) has 5 sections. The fourth tarsal segment is lobed.

These guys show up late every summer and seem to only have one thing in mind. I find them everywhere except on my goldenrod. They love my panicle hydrangea. Wish they would eat the millions on aphids on my common milkweed!

Here are a couple of pictures of a bee variety I do not recognize. They came to our allium this afternoon. Still feeding. Hundreds of them on three plants. On the hydrangea adjacent!

Neighbor’s goldenrod is COVERED in these!  Glad we finally found out what they are. They don’t seem to disrupt the bees at all, and now I want to introduce them to a neighbor across the alley with an aphid problem!
