| description | 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 of the species is reconsidered
and its northern border Central Asia is determined.
Literature information on biotopic associations and host
plants is summarized. Adults and larvae hibernate. There
are two generations per year. The eggs of the first generation
are laid in February. This generation is not numerous
and specimens rarely observed. The adults of the second
generation appear from the end of July to the beginning of
August and immediately begin to copulate and oviposite.
The females with well-developed eggs are observed until
the end of September and larvae of any stages can be found
from August to the second half of October, when they start
hibernation. Each clutch contains up to 70 eggs positioned
in chess order. Eggs development takes 9-10 days. Mean
size of an egg is 0,82x0,59 mm. Six new host plants are recorded
belong to Chenopodiaceae. Immature stages of Ch.
ornatula are described. |
