Abstract Department of Zoology, Butterflies use Chromolaena odorata (Asteraceae) flower as an important source of nectar. A survey was Jahangirnagar University, conducted to investigate the diversity of butterflies in relation to C. odorata (L.) in two selected Savar, Dhaka, Bangladesh. geographically different areas namely Kaptai National Park and Jahangirnagar University Campus during the period of December 2011 to January 2015. A total of 55 species of butterflies belonging to 06 Nasima Kabir families were recorded during this survey period of which 35 species of 28 genera were recorded from Department of Zoology, Kaptai National Park and 26 species of 23 genera were recorded from Jahangirnagar University Campus. Jagannath University, Dhaka- Six different species which include Acraea violae, Catopsilia pomona, Papilio demoleus, Eurema 1100, Bangladesh. hecabe, Cethosia cyane and Tagiades japetus were identified in the both areas.

Introduction Although a significant majority of butterflies have strong interactions with flowers, plants and other biotic components of any ecosystem but the information about butterfly species and their nectar-host plant relationships in Bangladesh are scanty [1, 2]. Floral attributes are well known to influence nectar-feeding butterflies. The diversity of butterflies for particular habitats is associated with the availability of larval host plants and adult nectar plants. Many of the flowering plants are used by butterflies as nectar plants and support a rich diversity of butterflies. Butterflies have been found to differ in the range of available nectar sources used [3, 4]. The Chromolaena odorata (L.) (Asteraceae) florets attract butterflies and an important nectar [5] source for adult butterflies . However, C. odorata (L.) is a scrambling perennial shrub, with straight, pithy, brittle stems which branch readily, bear three-veined, ovate-triangular leaves placed oppositely, and with a shallow, fibrous root system invasive plant found in the humid tropics and sub-tropics worldwide [6, 7, 8]. Capitula are borne in panicles at the ends of the branches and are devoid of ray florets. The corollas of the florets vary between plants from [7, 9] white to pale blue or lilac. Achenes are black with a pale pappus . In open-land situations, C. odorata grows to 2–3 m in height, but it can reach up to 5–10 m when supported by other vegetation. It shows marked morphological variability in terms of flower color, leaf shape and hairiness, smell of the crushed leaves and plant architecture. In some regions, several forms and their intermediates co-occur, while in others, the population appears homogeneous; the [10] basis for this variability presently remains unexplained . It flowers during October-February. The inflorescences consist of corymbs of cylindrical heads and the floral characteristics such as white to purple colour of florets, short-tubed narrow corolla with deep seated nectar, the morning anthesis and the flat-topped head inflorescence providing a standing platform are important attractants for visitation by butterflies [5]. However, this paper presents the diversity of butterflies in relation to C. odorata (L.) in two selected geographically different areas Correspondence: namely Kaptai National Park and Jahangirnagar University Campus Tahsinur Rahman Shihan Junior Wildlife Researcher, 2.

It was declared as a National Park by the Government Jahangirnagar University, of Bangladesh in 1999. It is situated in the Kaptai sub district under Rangamati district in Savar, Dhaka, Bangladesh. southeast Bangladesh (22030.08´ N latitude and 92016.02´ E longitude).

It consists of evergreen forest and plantation areas has diverse habitat for 280 hectares of area. JU campus has diverse ecological butterflies such as grassland, bushes, marshy areas and habitats and vegetation types. It consists of woodlands, cultivation fields [11]. The main study area was the forest near jungles, grasslands, rice fields and vegetables gardens. Some the new Rangamati road, where the plants grow enormously. of the water bodies reside in the campus.

Regular observations on the butterflies, visiting genera, Papilionidae represents 04 species belonging to 03 the flowers for forage were made during the flowering period genera and while Riodinidae represents only 01 species of the plants [5]. The observation period was at least seven days belonging to 01genera. Among members, genera Delias and per month (October, November, December, January and Junonia found most (both 04 members) of family Pieridae and February) during the course of the survey.
