Preimaginal stages of Chroantha ornatula (Herrich-Schaffer, 1842) (Heteroptera: Pentatomidae) in Central Asia

The description of previously unknown immature stages of Chroantha ornatula (Herrich-Schaffer, 1842) is given. Collection and observation were made during 1987-2002 in Turkmenistan. Observations on the eggs and larval development were made in the nature and in the laboratory cages. Distribution...
