Abstract
Aim. Despite the fact that the Caucasian dragonflies dedicated to dozens of publications and has a General idea about the original fauna of dragonflies in this region, still many unclear issues about the status of many species, their spatial distribution, characteristics of the life cycles and ecology of dragonflies in a kind of mountain conditions. The research objective of this work is to study the species composition and geographical distribution of the fauna of dragonflies of Dagestan. In this regard it took to solve the following tasks: to conduct a detailed study of the fauna of dragonflies as the least studied in odonatological respect, to analyze the composition of the fauna of dragonflies, to compare the composition of the fauna of dragonflies Caucasus and Dagestan. Methods. As the largest of modern insects, leading to the same open and active lifestyles, adult dragonflies easy to observe in nature, getting in a short time without bulky equipment material for a variety of biological problems. Material for this work, we used our own fees, collection materials, and literature. Results. For the first time for the area analyzed the composition of the fauna of dragonflies, which includes 42 species belonging to 8 families. The results not only significantly improve old ideas about the composition of the fauna from Russia, territorial distribution, which is important in terms of learning about biodiversity, but also contribute to the overall biogeography. Main conclusion.There are 82 species, distributed in 27 genus, 10 families, and 3 suborders in the fauna of the Caucasus at the present time. There are 15 genus of 27 presented in the fauna of Dagestan in all in the Caucasus

Summary
Следует отметить и роль стрекоз как носителей уникального генофонда, что побудило взять под охрану редкие виды этих насекомых. Проводится сравнительный анализ фауны Кавказа и Дагестана. С Кавказа описано несколько эндемичных видов и форм этих насекомых. В данной статье приводятся результаты исследования видового состава и географического распространения фауны стрекоз Дагестан. В связи с этим потребовалось решить следующие задачи: провести детальное исследование фауны стрекоз как наименее изученных насекомых, чтобы проанализировать и сравнить состав фауны стрекоз Кавказа и Дагестана. Впервые для района исследования проанализирован состав фауны стрекоз, которая включает в себя 27 видов, принадлежащих к 15 родам. Результаты проведенного нами исследования не только значительно пополняют старые данные о составе фауны стрекоз России и Кавказа, их территориальном распределении, что важно в плане изучения биоразнообразия региона, но также содействуют развитию и расширению общей биогеографии. Ключевые слова: Стрекозы, Кавказ, Дагестан, насекомые, род, вид, родовой анализ, видовой состав
