Wild life of the Kargil and Leh Disticts (Ladakh Region) has been studied since long but very few literary information is available on the insects inhabiting the area. According to a report published by WWF- India Ladakh especially the Kargil district is poorly studied in terms of its biodiversity and potential impacts of climate change. study to know and know to conserve.

ABSTRACT
High altitude region (Cold Desert) of Himalaya comprises twin districts of Kargil & Leh. Kargil district ranges from an altitude of 2704 m – 7135 m above sea level was studied during the year 2007-08 to report the diversity of insect fauna of family Coccinellidae (Coleoptera) from three different altitudes viz; low, medium and high of the area. Five Coccinellid species viz; Adalia sp., Hippodamia variegata., Coccinela sp., Coelophora sp. and Halyzia sp. were recorded during the survey. Further studies with regard to their diagnostic features are also incorporated in this communication.
Key Words: Kargil, high altitude, Cold desert, diversity, Coleoptera.
INTRODUCTION:
Coccinellidae is a family of beetles, known variously as ladybirds (British English, Australian English, South African English), ladybugs (North American English) or lady beetles (preferred by some scientists) *(Wikipedia). Lesser-used names include ladyclock, lady cow, and lady fly **(Definition of lady cow). Coccinellid beetles belonging to the super family Cucujoidea, which in turn belongs to the series Cucujiformia within the sub order Polyphaga of the beetles (Coleoptera). Worldwide, nearly 5,200 species of ladybirds are known Hawkeswood, (1987). Moreton (1969), Hawkeswood (1987), Majerus (1994) and Khan (2001), c.f. Khan et al, (2006) considered many species of Coccinellids as major biological agents in controlling pests like aphids, mealybugs, scale insects, thrips and mites in all parts of the world. Most species of ladybird beetles are considered beneficial because they are predators of Homoptera or Acarina, many of which are considered to be pests. A contemporary basis for an understanding of this family in North America was provided by Gordon (1976, 1985). These predatory ladybirds contribute to the regulation of populations of their prey, and in some situations contribute a high level of regulation. Some are specific in their
food choice, while many are polyphagous. Kargil district lying in the northwest Himalaya is a cold desert and the terrain is very difficult to study insect diversity. This observation is just a preliminary attempt to study the diversity of this family in this cold desert.
MATERIALS AND METHODS:
Area of Study:
The study area was located in Ladakh region of the J&K State at an altitudinal range of 2,636 meters above sea level lying in between 34o36′ North Latitude and 76o06′ East Longitude. Topography variable, ranging from 2,636 meters up to 7,135 meters, comprises of maze of valleys. Most of the area is barren with high slopes. Only areas having water source are seen with good amount of vegetation. Average rain fall is very low and that too mostly in the form of snow during winter months. The study area experienced both arctic and desert climate and commonly known as “Cold Desert” of the country.
Methods:
For detail investigation of these families, data was gathered fortnightly at 3 different areas with different altitude and habitats viz., Poyen (2,636.36 - 2,727.27 m asl) having crop land and forest, Kurbathang (2,757.57 - 2,878.78 m asl) with mainly alfalfa fields and Goma-Kargil (Goma-Kargil 2,909.09 - 3,030.30 m asl) provided with sparse vegetation of xerophytic type of the Kargil town within Kargil district.
Adult beetles were collected from the area under investigation by traditional methods like hand picking, using hand net and some times also by stem beating at fortnight intervals during (March 2007 - February 2008) in five different study plots of 5 square meter area in each of the three stations.
After collection the insects were killed by using ethyl acetate either in the killing bottle or by introducing cotton balls dipped and subsequently squeezed in ethyl acetate in closed polythene bags. After killing the beetles were pinned/ cardened, stretched and dried in oven and get identified from IARI, New Delhi.
RESULTS AND DISCUSSIONS:
A total of 580 specimens were collected and classified belonging to five genera, Hippodamia variegata, Adalia sp., Coccinella sp., Halyzia sp. and Coelophora sp.
