Opis:
Biodiversity declines due to unplanned urbanization as well as anthropogenic activities. It has already been documented that native flora and fauna are disappearing as an impact of biodiversity loss. There should be urgent need to restore our lost habitats through conservation techniques. The present study was aimed to conserve and restore lost habitat of pollinators with special reference to butterflies in an urban area through setting up a garden. The study was divided into two phases. In the first phase survey of butterflies found within an unmanaged garden in the campus (Lady Brabourne College, Kolkata) was performed prior to construction activity (May 2012 to October, 2012) and it was observed previously total 31 species of butterfly visited the garden. Developmental activities caused a sharp decline in their population causing an approach to relocate our garden in another area of college campus. In the second phase, setting up a garden in an alternative sites of same campus with plantation of host plants preferred by butterfly species was done and observed for butterfly visit. A slow increase in sighting over a study period of two years (between October, 2012 to June, 2015) was recorded. The results clearly indicate that total 43 species of butterflies were recorded in the garden including 9 species, which were not seen before and with 8 species completing their life cycles. In conclusion, declining of butterfly species can be increased and conserved through setting up of a garden. Presently the garden is flourishing but problems of increase in natural enemies as birds and other anthropogenic disturbances such as excess noise and vibration, street lighting, human interference etc. should be addressed in future within present conservation approach.

Opis:
Nectar is the primary nutrient source for adult butterflies. Plant species vary in their nectar content that may influence the biological attributes of the dependent life forms. Butterflies too differ in the range of available nectar resources for exploitation. Seven flowering plant species were selected in the study area, Kisholoy, Juvenile Detention Center, Barasat, where butterflies visit the most. Data was generated from three individual plants of each of the seven plant species. Each plant individual was observed for scheduled time period in the morning to record the encounters of butterfly species. Thirty eight [38] butterfly species of five [5] families were recorded during the study period. It was found that, the encounter frequencies of butterfly species varied for different nectar plant species. It was also observed that butterflies of a particular family preferred a specific nectar plant species or even a particular plant of a selected species. None of the seven nectar plants did attract members of all the five butterfly families. Lycaenids were found to be the most frequent visitors in different nectar plants like Aerva lanata, Acmella uliginosa and Sida sp. In case of Mikania micrantha, nymphalids were frequent visitors following lycaenids.

Opis:
Coloration and mimicry are the naturally selected survival tools for lepidopterans, both in larval and adult life either playing the protective or aggressive or advertising or cryptic or camouflaging mechanisms. Besides being nature’s priceless artwork, butterflies are one of the most beneficial terrestrial insects, playing a major role as pollinators and an essential component of commercial agriculture, horticulture, wild plant and animal diversity. They also play role as bioindicators. The natural distribution of butterfly populations in any local habitat is primarily defined by the distribution of their nectar plants and larval host plants as there exist species specific relationships among the host and nectar plants and the dependant butterflies. Also there exist specific ecological and functional correlation among the mimetic forms (the models and mimics and the individual members of a mimicry-complex or Mullerian ring) found in any particular habitat. The present study is focussed on observation, documentation and analysis of mimetic butterflies commonly found at Taki, North 24 Parganas; availability and prominence of mimicking sets, their intra- and interfamily relationships, reporting about their larval host plants and nectar plants. The study also has an importance from conservation approach.

Opis:
The aim of this study was to determine the effect of butterfly pea leaf as a source of carotenoids on the quality of the color of the heads of swordtail fish. The study was conducted at the Aquaculture Laboratory, Building 4, Faculty of Fisheries and Marine Sciences, Padjadjaran University, from March to April 2019. The research method used an experimental approach with Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications. Those treatments are 0%, 1%, 6% and 12% of butterfly pea leaf meal. The parameters observed included changes in head color quality, absolute weight growth, absolute length growth and water quality. Color observation data were analyzed using Kruskal-Wallis analysis if there were differences between treatments. Multiple comparisons were performed with the Z test with a confidence level of 95%. Data on the length of growth rates and absolute weights were analyzed using analysis of variance via the F test. Here, 95% was set as the confidence level. If there were differences between treatments, this was followed by Duncan test with a confidence level of 95%. The results showed that the addition of 6% butterfly pea leaf meal in commercial feed was able to improve the best color on the part of the swordtail fish head. This saw an average color score 9.56 and color value of 82.2. Addition of carotenoids in feed, however, did not significantly influence the growth of absolute weight or length and water quality.

Opis:
67 species of butterflies under 5 families and 51 genera were recorded from Haldia industrial beltand adjacent rural area. Industrial zone hadfewer species low diversity and evenness indices and high dominance index. Nymphalidae outnumbered all other families in the industrial zone with 48% of the total species of that area. Such preponderance of any single family was not evident in the rural area, likewise industrial belt had 3 dominant species but no dominant species could be seen in the rural zone. Results suggest that industrialization could alter the butterfly diversity but it was not enough to make the two sites dissimilar as revealed by the index of similarity (0.52).

Opis:
Understanding the significance of butterflies in an ecosystem as an environmental healthy indicator and pollination of flowering plants is crucial to achieve sustainability and conservation of floral diversity. The aim of the study is to investigate the butterfly species diversity and abundance and compare the relationship between physical factors and butterfly species at Taki, North 24 Parganas. Survey of six habitats, each containing specific ecological and socio economic profile was conducted. Diversity varies among habitats. Seasonal parameters also play vital roles as the distribution factors for local butterflies. A checklist is made comprising a total of 51 butterfly species belonging to 5 families. Sixty eight species of plants belonging to 28 families served as the larval host plants and 36 species of plants belonging to 20 families served as the nectar plants for butterflies. Maximum number of individuals found at SC (Surrounding College, College Ground, College Hostel Ground) site. The highest species richness and abundance are reported during the post monsoon. The abundance pattern is correlated to the foliage and nutritional support provided by the host plants, both at developmental and at adult stages. Nymphalidae is the most dominant family with 37% of the total number of species.
