Abstarct: Predatory ladybird (Coccinellidae) plays an important role in maintaining ecological balance of aphids, mites, psyllids, thrips, scale insects and larvae of some insects with complete mextamorphosis in different ecosystems.Due to the significant role that predatory ladybird plays in the integrated pests of management, the study of coccinellid fauna was conducted in this area to understanding this benefical components in different ecosystems. Samples were collected during different seasons of year from fruit, ornamental and herbaceous plants. Sampling were carried outusingswept net,shaking the tree branches on a white tray and direct collectingby hand. Overwinterng place including; under tree bark, the residues of plant and under rocks and hunks andamong the dry leaves and seam of walls. Collected ladybirds were then transferred to the laboratory and were put in glass containing 75% alcohol. Morphological characteristics and genitalia of males and females were used for identification. To prepare microscopic slides, body parts boiled in KOH10% and after washing and dewatering the alcohol of 50%, 75% and 96% on the slide has stabilized. Using resources and identify keys was done identification of samples.In thesurvey a total of 20 coccinellid species belonging to 14 genera was identified.that the ladybirds; coccinellaseptempunctata L. 1758, Hippodamiavariegata (Goeze)1777, Oenopia conglobata (L.) 1758, Adalia bipunctata (L.) 1758 were evaluated asdominant species.Meanwhilefor some collinellid species, different morphes were distinguishedbaxsed on adult morphological characteristics including body color, size, pattern and spot numbers on dorsal surface of the elytra and pronotum 26, 18 and 8 morphs were found for H.vareigata, A. bipunctata and Adalia decempunctata (L.) 1758 respectively. The results suggest to protect the domonent species in theirs natural habitat.List of identified coccinellids are as follows: Coccinella septempunctata L. 1758, Hippodamia variegata (Goeze)1777, Coccinella undecimpunctata L. 1758, Oenopia conglobata (L.) 1758, Oenopia onica (Olivier) 1808, Adalia bipunctata (L.) 1758,Adalia decempunctata (L.) 1758, Adalia tetraspilota Hope 1831,Psyllobora vigintiduopunctata (L.) 1758, Propylaea quatuordecimpunctata(L.) 1758, Harmonia quadripunctata (Pontoppidan) 1763, Bulaea lichatschovi Hummel 1827, Chilocorus bipustulatus L. 1758, Exochomus quadripustulatus L. 1758, Parexochomus nigromaculatus (Goeze) 1777, Clitostethus arcuatus (Rossi) 1794, Scymnus (pullus) subvillosus Goeze 1777, Scymnus (Scymnus) flavicollis Redtenbacher 1843, Stethorus sp., Hyperaspis femorata (Motschulsky)1837.
