“There is nothing in a caterpillar that tells you it's going to be a butterfly." R. Buckminster Fuller The Section Cerulean of the Butterfly Sanctuary Akila Weerakoon Research Scientist/SLWCS The work on the Butterfly Sanctuary is progressing well. Seventy five percent of the invasive Ipil Ipil (Leucaena leucocephala) has been removed and the balance 25 percent will be removed by the end of April. A pond has been dug and it’s now in the process of having the banks shaped and filled with natural mud to make it waterproof. The first batch of host plants has been planted. The selection, procurement and planting of the second batch of host plants are in the planning stages. Volunteers assisting to remove the invasive Ipil Ipil Siriya taking a break from removing Ipil Ipil Fifty percent of the footpaths had also being completed. This is taking a bit longer since we are making sure these paths do not intrude into butterfly habitats. The footpaths are laid in a manner to provide the least intrusive access to observe butterflies without disturbing them. An irrigation system to keep the sanctuary irrigated during the dry season is being installed and will be also completed by the end of April. A footpath Pipeline to install the irrigation system Documenting of species both plants and butterflies is ongoing. We are very excited to record another additional butterfly species, the Dark Wanderer (Pareronia ceylanica ceylanica) belonging to the family Pieridae now present in the Butterfly Sanctuary. This brings our current list of recorded butterflies to 18 species since we started work on the Butterfly Sanctuary.
