The paranota of Pseudacysta are present only as small ear-like flaps on humeri. References differ as to whether P. palustris is a valid species. Persea grattissima Gaertn. F. is a synonmy of P. americana . In the northern part of peninsula Florida, and other parts of the Deep South, camphor is the main host.
Avocado is the main host in the southern coastal region of Florida.
It usually lives in colonies, depositing eggs upright in irregular rows in clusters on the lower leaf surface. The extraction of the juices from the foliage causes a gradual localized destruction of the plant cells. The resulting chlorotic areas correspond to the location of the lace bugs below. Where a colony of these insects is present, the eggs and the lower surface of the leaf are more or less thickly covered by a dark, sticky secretion from the insects. The principal injury, however, is the destruction of the leaf cells due to the sucking habit of the insects.
