A total of 15 species of tger beetles (subfamily Cicindelinae) belonging to seven genera were recorded from forest, moist and dry riverine ecosystem using an occasional night trap. Eight species belonging to fve genera were recorded from the riverine ecosystem. Two species, viz., Cylindera spinolae and Calochroa assamensis, were strictly restricted to the forest and Cosmodela virgula was recorded from both forest and riverine areas. Cylindera (Eugrapha) minuta, Calochroa favomaculata, and Lophyra (Spilodia) vitgera were collected using a night trap from the forest area. The study revealed that habitat degradaton due to human interference is the major threat to the tger beetles in the study area.

INTRODUCTION (1863), Atkinson (1889), and Horn (1905a,b), though the frst comprehensive list of all genera of tger beetles of Tiger beetles are charismatc, fast running, and the Indian subcontnent was published by Fowler (1912). predatory insects under the subfamily Cicindelinae and Afer independence, Pajni & Bedi (1973) reported a family Carabidae. Cicindelinae is characterized by large preliminary survey of the cicindelid fauna of Chandigarh. compound eyes, fliform and 11-segmented antennae, Pearson & Ghorpade (1987) studied the geographical long legs, and long sickle-shaped mandibles. The size distributon and ecological history of tger beetles of the of tger beetles varies from 6–45 mm. They are adapted Siliguri-Darjeeling area of eastern India. Later, Bhargav to diferent habitat types such as riverine sandy areas, & Uniyal (2008) studied tger beetles in the Shivalik stream and pond edges, hillsides, rocky areas near roads, Landscape. In 2008, Werner & Wiesner frst recorded trails, and forest openings. Though the tger beetle is Neocollyris (Leptocollyris) parvula (Chaudoir, 1848), mainly distributed in the tropical region, it is also found Calochroa bicolor haemorrhoidalis (Wiedemann, 1823) in Greenland, Tasmania, and some small oceanic islands and Cylindera (Ifasina) severini (Horn, 1892) from the such as Hawaii (Pearson 1988; Cassola & Pearson 2000; state of Maharashtra, Rajasthan, and Madhya Pradesh. Pearson & Vogler 2001). Bhardwaj et al. (2008) reported the occurrence of tger All tger beetles are highly habitat-specifc (Knisley beetles from Utarakhand. Tiger beetles of Meghalaya & Hill 1992; Adis et al. 1998; Cardoso & Vogler 2005; were exclusively reported by Sawada & Wiesner in 1997. Pearson & Cassola 2007; Raf et al. 2010). Each species Recently, Harit (2013) studied the diversity of tger prefer specifc habitats such as riverine habitats beetles in Mizoram of northeastern India. Invertebrates (Ganeshaiah & Belavadi 1986; Satoh et al. 2006; Dangalle are understudied overall, and for even some of the et al. 2011a,b), forests (Adis et al. 1998), agroecosystems taxonomically beter studied groups like tger beetles (French et al. 2004; Sinu et al. 2006), parks, areas with (Cicindelidae), knowledge is scanty from this part of the human disturbances (Bhardwaj et al. 2008; Mosley land. Keeping these aspects in view, an investgaton of 2009), open areas with sparse vegetaton (Schiefer the occurrences and preferences of habitats along with 2004) and grasslands (Acorn 2004). The associaton of their present threats in Chakrashila Wildlife Sanctuary tger beetle species with habitat has been related to and the adjoining riverine ecosystem in western Assam their preferences for matng and ovipositon sites, food of India was conducted. availability, seasonality, vegetaton cover and physical, chemical and climatc qualites of the habitat (Pearson et al. 2006). Most of the tger beetles are diurnal, some MATERIALS AND METHODS species are strictly nocturnal and many are cathemeral (Pearson 1988). Though several species living together Study area is common, there is very litle competton among them, Chakrashila Wildlife Sanctuary (26.250–26.433 partcularly because of niche parttoning (Pearson & 0N and 90.250–90.333 0E 4,500ha) is located in the Carroll 1998). districts
