Abstract : The author describes all stages of Lindingaspis ferrisi McKenzie, a Diaspidid that causes severe damage to a number of trees and shrubs in the Giza region of Egypt. A list is given of its known food-plants in that region; those most heavily attacked are mango, Ficus nitida and Laurus nobilis, but the list includes various other ornamentals and also olive. Damage is confined to the leaves.During laboratory studies on the bionomics of L. ferrisi females laid an average of 64.5 eggs each. For the females, the two nymphal stages averaged 30 and 15 days, respectively, in May and 25 and 20 days, respectively, in September; the adults lived for an average of 120-155 days. Males completed their development in an average of 45 days in May and 65 days in September, and the adults lived for 1-2 days. Males formed 28.2% of the population in March and 48.7% in September.
