Abstrakt: In a survey on the fauna of ladybirds which was carried out in Shahrood and Bastam regions during 2015, oenopia conglobata with a frequency of 11/23% relative to the other species was ranked fourth. The Ladybird has been introduced as a polymorphic species and is the most important natural enemy of pests such as aphids, psyllids and lace bugs that activity of them is proved on the non-fruit trees and fruit trees. Color pattern variation of the elytra and pronotum in Oenopia conglobata was studied on ornamental and forest plants in two differents weather conditions in Shahrood and Bastam regions. Samples were collected by net-trap and white-tray. After transferring to the laboratory, samples were placed in glass containers filled with 75% ethyl alcohol. Identification was based on the general morphological characters as well as their genitalia. Different morphs were identified based on morphological characteristics including color, size, pattern and number spots on dorsal surface of the elytra and pronotum. Five different morphs of O. conglobata were identified so morphs 4 and 2 had the highest and the least abundance, respectively. [ABSTRACT FROM AUTHOR]
