Abstract/ Executive Summary:

Butterflies use Chromolaena odorata (Asteraceae) flower as an important source of nectar. A survey was conducted to investigate the diversity of butterflies in relation to C. odorata (L.) in two selected 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 families were recorded during this survey period of which 35 species of 28 genera were recorded from Kaptai National Park and 26 species of 23 genera were recorded from Jahangirnagar University Campus. Six different species which include Acraea violae, Catopsilia pomona, Papilio demoleus, Eurema hecabe, Cethosia cyane and Tagiades japetus were identified in the both areas.

Objectives:

This paper presents the diversity of butterflies in relation to C. odorata (L.) in two selected geographically different areas namely Kaptai National Park and Jahangirnagar University Campus

Methodology:

Study area Kaptai National Park: Kaptai National Park (KNP) is a mixed evergreen forest with some areas of planted Tecktona grandis. It was declared as a National Park by the Government of Bangladesh in 1999. It is situated in the Kaptai sub district under Rangamati district in southeast Bangladesh (220 30.08´ N latitude and 920 16.02´ E longitude). It consists of 5464.8 hectares area and it is 1600 ft. high from sea level. This mixed evergreen forest and plantation areas has diverse habitat for butterflies such as grassland, bushes, marshy areas and cultivation fields. The main study area was the forest near the new Rangamati road, where the plants grow enormously. Jahangirnagar University Campus: Jahangirnagar University campus (JU C) is situated at the central region of Bangladesh. Geographically the campus is at 30⁰ 16´N latitude and 90⁰ 52´E longitude, which is about 33 km north-west from Dhaka city and elevation 39 ft. from sea level. It consists of 280 hectares of area. JU campus has diverse ecological habitats and vegetation types. It consists of woodlands, jungles, grasslands, rice fields and vegetables gardens. Some of the water bodies reside in the campus. All of these features make the present study area as an ideal habitat for various kinds of wildlife and incalculable number of insects. In and around the botanical garden of this university was the main habitat for this plant. Collection and identification of butterflies: The study was carried out during December 2011 to January 2015 in two selected areas. Regular observations on the butterflies, visiting the flowers for forage were made during the flowering period of the plants [5]. The observation period was at least seven days per month (October, November, December, January and February) during the course of the survey. Butterfly species were identified directly in the field by visualization and photodocumentation by Nikon Coolpix P100, Canon DSLR 1100D and 55-250 mm lens and with the help of field guides followed by photography, in difficult cases, rarely by capture. Identification, scientific names and common names of butterflies is after Evans (1927), Wynter-Blyth (1957), Marshall & de Niceville (1883), Bingham (1905), Kunte (2000), Larsen (2004), Kehimkar (2008) and Kunte et al. (2012)

Achievement/Findings:

Butterflies get a source of large amount of nutrition from C. odorata flowers and pollinate the flowers heavily, which is the key success of its highly invasiveness of different parts of the world.
