Abstarct: Ladybugs belonging to the Coccinellidae family are predators. They play a very important role in controlling some pests, including the larvae of some insects, weevils, mites, thrips, and psyllids. Due to the important role of these ladybugs in integrated pest control and management, their faunal study was conducted to identify these beneficial insects in sarakhs ecosystems. The specimens collected from the Fern region were all reported for the first time from this region. Ladybugs were collected in various ways, including using insect nets, shaking branches on a white tray, and direct hand picking. These insects were collected from different plant hosts such as herbaceous plants, fruitless and fruitless trees. During winter, it was observed and collected under plant remains, under tree bark, under dry leaves at the foot of trees, under stones and lumps, and in the seams of walls. A number of samples were delayed and the samples were identified using valid identification keys and sources. Examining the frequency of the samples showed that ladybugs 1758 Coccinella septempunctata L., Hippodamia variegate (Goeze) 1777, 1758 Oenopia conglobate (L.), Adalia bipunctata (L.) 1758, L. 1758 Coccinella undecimpunctata are the dominant species of sarakhs. . Also, in this research, different forms of some ladybug species were investigated and separated according to morphological characteristics, such as the pattern of the wings and its color, the size of spots on the wings and pollen. In total, 6 morphs of A. bipunctata, 2 morphs of A. tetraspilota, 5 morphs of O. conglobate and 21 morphs of H. variegate were identified. This research can provide the basis for further research in the field of better and practical use of these beneficial insects in the biological control program. The ladybugs collected from the Fern region are as follows. Coccinella septempunctata L. 1758, Hippodamia variegate (Goeze) 1777, Coccinella undecimpunctata L. 1758, Oenopia conglobate (L.) 1758, Adalia bipunctata (L.) 1758, Adalia tetraspilota Hope 1831, Psyllobora vigintiduopunctata (L) 1758, Hyperaspis femorata ( Motschulsky) 1837.
