Tuliptree scale
The tuliptree scale, Toumeyella liriodendri, is also a large soft scale insect in the United States. It is often misidentified as the magnolia scale that is larger and has a similar life cycle, but only attacks magnolias. The tuliptree scale is a key pest of yellow poplar or tuliptree, magnolia (star magnolia, Magnolia stellata, saucer magnolia, M. soulangeana, and southern magnolia, M. grandiflora), and occasionally linden, Tilia spp., redbud, Cercis canadensis, walnut, Juglans spp., and hickory, Carya spp. This soft scale insect is so prolific that it quite often covers twigs and branches.
