Body oval or elongate oval. Dead females are reddish brown. Coloration of living stages has not been reported, possibly pale brown or whitish as Cockerell (1893o) described for immatures. A long, bright yellow ovisac is formed under and behind the adult female; the ovisac has longitudinal ridges described as "trifid" by Cockerell. Eggs are laid in the ovisac. Females apparently occur on the undersides of leaves. Males have not been reported.
This species was intercepted 6 times at U. S. ports-of-entry between 1995 and 2012, with specimens originating from Guatemala, Mexico, and Puerto Rico. We also have examined specimens from Belize (Carica), Guatemala (Codiaeum), Mexico (Ananas, Codiaeum, Ficus, Magnolia), and Puerto Rico (Acuba). ScaleNet includes hosts in Euphorbiaceae, Lauraceae, Magnoliaceae and Moraceae. It is most commonly intercepted on Annona. ScaleNet distribution records for P. lutea include Mexico (Colima) and The United States of America (Texas) in the Nearctic zoogeographic region, and Guatemala in the Neotropics. Three other species of Philephedra other than P. broadwayi (Cockerell), P.lutea and P. tuberculosa Nakahara & Gill have been taken at U. S. ports-of-entry: P. floridana Nakahara & Gill (Honduras, on unknown leaves); P. cresentiae (Cockerell) (Mexico, on Leucaena); and P. parvula Cockerell (Mexico, on Leucaena).
