Abstract The butterflies have great aesthetic and commercial values as they are beneficial as pollinator and environmental indicator. In this study, 21 species were identified belonging to 3 different families and 6 subfamilies from Kohat, Pakistan during September-December 2008. Of the reported families, Nymphalidae covered 33%, Papilionidae 10%, and Pieridae 57% of total numbers of collected butterflies of Kohat. Six species were belonging to subfamily Nymphalinae and one to Satyrinae. Two species belong to Papilioninae, the only subfamily of Papilionidae. The family Pieridae includs 3 subfamilies namely Pierinae, Coliaclinae and Coliadinae contained 5, 1 and 6 species, respectively. The minimum wingspan of collected butterflies belongs to the little orange tip, Colotis etrida Boisduval (25 mm) which was the smallest butterfly, however, the maximum one belongs to the lime butterfly, Papilio demoleus Linnaeus (100 mm) as well as the common mormon, P. polytes Linnaeus which were the largest butterflies. A detail study is required for further exploration of butterflies’ fauna of Kohat. Keywords: Butterfly, Kohat, Lepidoptera, wingspans 1. Introduction Of the 1.4 million species on the earth planet, over 53% are insects, while about 15,000-16,000 species of butterflies are known worldwide (Hassan, 1994). Lepidoptera is one of the most widespread and widely recognizable insect orders in the world. The term was coined by Linnaeus in 1735 and is derived from ancient Greek words for scale and wing. Linnaeus in Systema Naturae (1758) recognized three divisions of the Lepidoptera: Papilio, Sphinx and Phalaena, with seven subgroups in Phalaena. These persist today as 9 of the superfamilies of Lepidoptera. Comprising an estimated 174,250 species, in 126 families and 46 superfamilies, the Lepidoptera show many variations of the basic body structure that have evolved to gain .

Recent estimates suggest that the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera and the Coleoptera (Powell, 2009). More than 5,000 species of insects including 400 species of butterflies and moths have been reported from Pakistan (Khan et al., 2000 and 2007). Butterflies have been regarded as the symbol of beauty and grace (Rafi et al., 2000). They are the best known insects due to their diurnal habitats and readily recognized by their bright colours, marvelous shapes and graceful flight give pleasure to everyone (Javaid, 1978). They are beneficial as pollinator, environmental indicator and have great aesthetic and commercial values (Ahsan and Javaid, 1975). Kohat is bounded on the north by Peshawar and Nowshera districts, respectively, on the east by Attock, the south by Mianwali of the Punjab province and Karak district and on the west by Hangu district and Orakzai agency of FATA. The total area of the district is 2545 km2. The Kohat valley is the most important agriculturally rich area. Generally, the district is elevated and attained only inconsiderable heights above the plain area. The headquarter town of Kohat is more than 550 m above the sea level (Schmitt, 2007). Its climate is hot from May to September with the hottest in June. Minimum and maximum temperature recorded during June is about 27 °C and 45 °C, respectively. A pleasant change in the weather is noted from October onwards up till February. The winter is cold and severe with minimum and maximum temperature recorded during January about 2 °C and 6 °C, respectively. The rainfall is throughout the year and the monsoon rain from May to October. August is the rainiest month with an average of about 111 mm. The average annual rainfall is about 546 mm. The maximum humidity has been recorded in August during summer and in December during winter (Figure 1; Shah et al., 2001). The common trees in this area are Ber, Surgulla, Sanatha, Phulal, Olea etc. All kind of roses, bougain villea, kashmalo, gul-e-nargis, gui-e-dawoodi and other seasonal flowers are planted. Common wild life species found are hare, jackal, wolf, fox, wild cat, chakor, black partridge, grey partridge, urial, chinkara, blue bull, hogdeer, water fowl, see-see etc. The major crops grown in the district are wheat, maize, chari and sugarcane (Figure 1; Ajaz et al., 2003). Some biologists have made efforts to identify butterfly species, distribution and status. Pakistan Museum of Natural History (PMNH) and Oxford University Museum (OUM) have been studied insect diversity from Gilgit along Karakoram Highway to the Sino-Pakistan border at Khunjerab pass and several selected valleys (Khan et al., 2000 and 2004). By 1999, they had recorded about 100 species of butterflies, with new Texa. For example about 40 species of butterflies were recorded in Hunza during 2000 expeditions. Another document was reported on butterfly diversity in Skardu, Shigar, Karmang, Sadpara, Kachura and Deosai plains (Abbas et al., 2001 and 2002). Animal coloration strategies have long been a topic of interest to naturalist and philosophers, and even featured prominently in Aristotle Historian Animalia, written more than 2000 years ago. In the nature, there are much beautiful colors on the wings of butterflies. Scientists are still baffled about exactly, how these colors are created. The diversity of colors and patterns on the wings of butterflies has caught the attention of evolutionary biologists for more than a century (Lennox and Aristotle, 2001). They are very sensitive to habitation degradation but also have a much more rapid passage of generation than higher vertebrates and hence can be quicker to react to small changes in their environment than those of other animals (Gardiner et al., 2005). The objective of the present research is to identify the butterflies’ fauna of Kohat for awareness and education. 2. Materials and Methods 2.1. Sampling and Identification The study area, Kohat is located between 33°-04’ and 33°-34’ north latitudes and 70°-29’ and 72°-01' east longitudes (Figure 1). Butterflies of different species were caught by the insect collecting net during September-December 2008 from 5 sites of Kohat region, i.e., the university campus, Thanda Dame, Company Bagh, KDA Park and Dodo Park. Each site was sampled after an interval of 3 days using an insect net. Butterflies have been put in the cyanide bottle for killing. Then they were placed on a board for 120 Perveen and Ahmad. 1 (2012) 119-129/ BUTTERFLY FAUNA (LEPIDOPTERA) OF KOHAT stretching their wings to measure their wingspan and inserted the insect pin into their thoracic region. When their wings dried, they were arranged in the wooden box, in different rows with the phenolphthalein balls for the protection from pests. They were identified comparing with already preserved specimen, internet, literature available (Sabir et al., 2000; Munir et al., 2007), keys (Abbas et al., 2002; Munir et al., 2007) and experts on the bases of their colors and spots which are present on their wings upper and lower side. Allspecimens were then properly labeled. Figure 1. Map of Kohat, Khyber Pakhtunkhwan, Pakistan, sites of sampling in bold font (OCHA Pakistan, 2009). 3. Results 3.1.

Discussion The present study was the second attempt to collect butterfly fauna of Kohat. Merckx and Van-Dyck (2005) stated that nectar of butterfly-pollinated flowers contained generally higher levels of amino acids than flowers pollinated by other animal. The butterflies play dual role, firstly as the pollinator, carries pollen from one flower to another and secondly their larvae act as the pest, injurious to various crops. Shah et al. (2001) made a survey of Kohat and collected 10 species belonging to only family Pieridae from seven different localities over a period of 7 months during 1999. The present survey was made in the same district and a total 21 species of butterflies were collected in which 21 species belonging to 3 different families from 5 different localities over a period of 4 months during 2008. The pioneer butterfly, Anaphacis aurota F.; African clouded yellow, Colias electo (Linnaeus); Eastern pale clouded yellow, Colias erata (Esper); Indian cabbage white, P. canidia (Linnaeus) and bath white, Pontia daplitdice Linnaeus were reported previously while not found presently. However, Catopsilia pomona, Colias croceus, Colotis protractus, Ixias pyrene, P. ajaka, P. napi and Belenoi aurota were reported presently while not found previously. This difference may be due to the weather during collection periods or collection error. Parchem et al. (2007) stated that evolution of wings and adaptive properties of butterflies were made them as a successful group on earth. The diversity of their shape, size and color patterns is a direct 126 Perveen and Ahmad. 1 (2012) 119-129/ BUTTERFLY FAUNA (LEPIDOPTERA) OF KOHAT reflection of the important role and wings have played in the radiation of insects. Therefore, during the present study wingspan of collected species has been studied. It was found that maximum wingspan was found in Pa. polytes (90–100 mm) and minimum was of Colotis etrida (25–45 mm). Verma et al. (2004) studied the genera of butterflies occurring in Pakistan, India, Sarilanka, Nepal, Bhotan, Bangladish and Myanmar. They reviewed and cited many taxonomical papers. Their index showed valid name of genus and species of butterflies from India region. They reported 15 genera of Papalionidae, 25 Pieridae, 6 Danaidae of the same country. The present research was conducted to determine butterflies fauna of Kohat region. Twenty (21) species were identified during the survey belonging to 3 families including 7 species of family Namphalidae, 2 of Papilionidae and 12 of Pieridae. Both studies were conducted in two different countries. The present study was restricted to a small area and collecting period was also short. Van-Lien and Yuan (2003) conducted their survey on the species composition, richness and abundance of Papilionoidea (excluding Lycaenidae) butterfly fauna in different habitats with various degrees of disturbance and altitudes in tropical forests at the Tam Dao National Park, the northern Vietnam in 2001. The results showed significant differences of butterfly diversity among the different habitat types and between the low and high altitude sites. The butterfly diversity, species richness and species abundance in the low elevation habitats were higher than in the high elevation habitats. The highest diversity of butterflies occurred in the mixed habitats of agriculture, scrub and clearing. During the present research, the surey was conducted in Kohat which is located between 33°-04’ and 33°-34’ north latitudes belonging to families Pieridae and Namphlidae and only 2 species was belonging to the family Papilionidae. It is expected, if collection should be made in more time and larger area great biodiversity would be observed. Sharma et al. (2006) studied the collection of butterflies from Punjab new campus area from June to September study was based on the relationship of temperature, humidity and population of butterflies the occurrence of butterflies was more in moderate temperature but in June and September there were decline. Relationship between temperature and population of butterflies was positive. However, Fitzherbert et al. (2006) studied the diversity and the distribution of butterflies in the context of ecological preference and altitude range, 90 species were recorded between Gilgit and Khunjerab at high altitude. Some of them were highly distributed but other are less tolerant species present in colonies. So isolation plays a very important role in evolution of many species and ecological races. In the future, further research should be conducted with respect to the mention factors in Kohat.
