Bees and wasps often visit magnolia or tuliptree scales during late summer early fall to feed on the honeydew. The presence of lots of bees and wasps around magnolia or tuliptrees may indicate an infestation close-by.
The ragged hole in one of the scales on the left has been tore open and killed by a beneficial insect, probably a lady beetle.
