Gallformers ID Notes

Near-spherical rosettes of tiny gray-green leaflets on the buds or stems of Artemisia dracunculus. The host was originally thought to be A. campestris but based on the comments of plant expert Patrick Alexander here and here the host has been changed to A. dracunculus. Observed in New Mexico, Colorado, Montana, and Minnesota. Likely the same as this.
