Magnolia Scales (Neolecanium cornuparvum) & Tuliptree Scales (Toumeyella liriodendri) are both classified within the soft scale group. However, unlike essentially all the other soft scale species they have crawler emergence in August & September instead of in June & July. This fundamental difference is important to recognize in order to time sprays & achieve best controls.
