In this study the polymorphism in elytra coloration
pattern in two spotted ladybird Adalia bipunctata
(Col.:Coccinellidae) was studied during 2009-2010 in
Mehriz region(Yazd province, Iran). A. bipunctata
has different color morphs and shows great variation
of pattern. The polymorphism exhibited by the
two-spotted ladybird in which specimens have a red
ground color and black spots (the typical morphs) or
a black ground color with red spots (the melanic
morphs) is a well known phenomenon. Altogether 17
morphs of A. bipunctata were collected and
identified. External characters plus characteristics
of the male and female genitalia were used in order
to diagnose. Polymorphism of
A.
bipunctata
was recorded for the first time from this region.
A. bipunctata
was predator of aphids, pseducos and psyllids on
fruit trees. Some morphs of
A. bipunctata
were also sent to Dr.Helmut fursch in Germany for
identification or confirmation. The Our results of
this study show that 17 different morphs of A.
bipunctata existed in the area.
