Lantana Camara and Butterfly Abundance in an Urban Landscape: Benefits for Conservation or Species Invasion?

Urban landscapes host a range of diverse plants that, in turn, facilitate maintenance of different species of pollinators, including butterflies. In this context, the importance of Lantana camara, an invasive plant species, was assessed highlighting its role in maintenance of butterfly diversity, using Kolkata, India as a study area. Initial study revealed consistent presence of L. camara in both urban and rural sites with at least 25 different butterfly species association. The proportional relative load and the preferences of butterfly species for the each plant species were inclined towards L. camara. Irrespective of the sites, the diurnal and seasonal variations in the butterfly species abundance varied with the flowering pattern of L. camara. A positive correlation of different butterfly species with the flowering time and number of L. camara was for all the sites. The segregation of the L. camara associated butterfly species was made following discriminant function analysis using the extent of flower density of L. camara as explanatory variable. Despite being an invasive species, it is apparent that L. camara can be a prospective host plant that facilitates sustenance of butterflies in both urban and rural sites. Thus, existence of L. camara in urban gardens and forests may prove beneficial in sustenance of the butterflies.
