Diversity of butterflies in an arboretum of Vadodara , Gujarat , India

Potent pollinators and ecological indicators, butterflies are important for estimating the general health of an ecosystem. Owing to the rich plant diversity (927 species), an arboretum in Vadodara, state of Gujarat, India was selected for surveying butterfly diversity. Our survey was conducted in all seasons for an entire year from October 2012 to October 2013 and revealed 61 species. Recorded were six species of Papilionidae, three species of Hesperiidae, 20 species of Nymphalidae, 13 species of Pieridae, and 19 species of Lycaenidae. Junonia dominated with five species, followed by Eurema (three species), Graphium (three species), and Chilades (three species). Our study gives a comprehensive insight into the species diversity and richness of butterflies in Vadodara and highlights the need to conserve rare and threatened butterfly species there.


INTRODUCTION
Biodiversity is important for estimating the general health as well as development of proper conservation plans for the entire ecosystem, especially in ecologically sensitive groups such as butterflies (Lepidoptera: Rhopalocera) (Chowdhury & Soren 2011).Butterflies are one of the best taxonomically studied groups of insects (Robbins & Opler 1997).New et al. (1995) called them the flagship taxa for invertebrate conservation, and the plight of butterflies has been a focus of entomologists for over a century.Lepidoptera are beneficial as pollinators, silk producers, indicators of environmental quality, and appreciated for their aesthetic value (Pollard 1991;Kunte 2000;Kumar 2012).The holometabolous life history of butterflies causes them to be exposed to a wide range of environmental influences, and they are highly sensitive to changes in temperature, humidity, and light levels (Erhardt 1985;Kremen 1992;Sparrow et al. 1994;Chey et al. 1997;Spitzer et al. 1997).
Increases in human population and advances in technology have directly affected the ecosystems of the world and many lepidopterans and other organisms cannot adapt these changes (Boonvanno et al. 2000;Brattstrom et al. 2008).Threats to the butterfly fauna include the use of pesticides, urbanization, intensive forestry, agriculture and exotic species (New 1997;Wagner & Van Driesche 2010).In addition, knowledge of butterfly diversity may aid as a substitute for plant diversity because butterflies are directly reliant on plants, often in highly co-evolved situations (Ehrlich & Raven 1964).
In this context, our study examines the diversity of butterflies in an arboretum and discusses the conservation needs of rare and threatened butterfly species.Studies in the past have been conducted on similar grounds in other nature parks and arboretums of the country (Raut and Pendharkar 2010;Patil & Shende 2014).

Study site
The study area includes 4.85 ha arboretum in the city of Vadodara, Gujarat state, India (22°19ʹ12.22ʺN to 22° 19ʹ19.95ʺN and 073°10ʹ47.40ʺE to 073°10ʹ42.85ʺE).The arboretum situated on the distal part of human habitation within the urban expanse of the city (Figure 1).Based on the botanical survey of Daniel & Nagar (2010) this arboretum harbors 411 species of angiosperms, including 129 species of trees, 32 shrubs, 24 climbers and 80 herbs.It also has 148 plots of different medicinal plants ( Daniel & Nagar 2010).Outside of the monsoon season that extends from mid-June to mid-September, the climate is dry.The average rainfall of the region is 93 cm whereas temperatures fall in the range of 12.5-40.1 °C (IMD 2014).

Field survey and data collection
Our survey was conducted in all seasons for an entire year from October 2012 to October 2013.Field observations were made on a daily basis between 10:00 to 17:00 h.Butterflies were recorded by visual observations, with the aid of binocular and a digital camera (Sony, HX100V).Butterflies were observed, photographed, and identified with the help of literature (Evans 1932;Wynter-Blyth 1957;Gay et al. 1992;Lewington 1999;Kunte 2000;Parasharya & Jani 2007;Kehimkar 2011).Some individuals of certain species were captured using a butterfly net, identified, and then released.Species richness was calculated as the total number of the species in a group in an area.

DISCUSSION
Butterfly diversity is largely dependent on a rich flora, because larval host-plant relationships are frequently so specific (Murphy & Wilcox 1986).Therefore, the conservation of butterfly diversity is achievable by the enhancement of vegetation in habitats specifically preferred by butterflies (Lawton et al. 1998).Some butterflies are ecological indicator species and play a vital role by cross-pollination of plants (Bonebrake et al. 2010).We found our study area to have a rich diversity of butterfly species, which include nine rare and threatened species listed under schedule I of part IV of the Indian Wildlife Protection Act, 1972.As butterflies are highly sensitive to human-induced changes to the environment, an assessment of their response to these changes is needed to identify the indicator species (Kremen 1992; Barlow et al. 2007).The baseline data that we present here can serve as a reference for similar future studies.Research on interactions of butterfly species with specific host plants, distribution of butterfly species, and priority areas for butterfly conservation will all be helpful to better understand the conservation needs of these creatures and the ecosystem as a whole.
