Certain biological aspects of Coranus aegyptius F. was studied in the laboratory according to literature for the first time by using Anagasta kuehniella Zell. larvae as prey under constant hygrothermal conditions of 30±1^°C and 70±5% R.H. The development stages of C.aegyptius were described and figured. The first to fifth nymphal instars lasted 6.5, 6.1, 5.7, 5.9 and 9.4 days, respectively in male. The respective values in female were 6.3, 4.6, 5.1 and 6.8 days. Adult female laid an average of 241.4 eggs and oviposition period of 145 days with a daily rate of 1.6 eggs/female lon­gevity of adult, and fecundity were estimated.
