Thread: sedum pests

  1. #1
    I need help identifying a pest*infestation I found on our autumn joy sedums.* Several stalks have been hollowed out and replaced with what looks like red mud...similiar to*a mud dauber's nest.** When I broke the stalk open, small white insects were inside...they had no wings or antennae but had mandibles.

    Hi Carolina Mtn Gardener,

    I'm not finding much info on insect pests and sedum.* You obviously have the larval stage of some pest.* I do find reference to black vine weevils, but the feeding habits of the larvae are to feed on the roots.* The adults do notch the edges of the leaves of plants, often making them look scalloped.* Do you see anything like that?

    Here's a root weevil grub on a sedum.

    Here's the damage.

    I would definitely cut off the stems of any infected plants and destroy them.
