For those of you who aren't aware, 'butterfly month' commenced on September 1 and this activity was organised by the Conservation Education Centre (Delhi wing of Bombay Natural History Society), in a bid to record butterfly species.


Butterfly month aims to provide an accurate and updated list of butterfly species found across NCR, the results of which will be announced on September 23.


According to a report in the Times of India (TOI), over 15 locations across NCR were covered on Sunday, including Yamuna Biodiversity Park, Aravalli Biodiversity Park and Okhla Bird Sanctuary, among others.


Each team was allotted an expert team captain with a checklist provided to each participant where they could spot butterfly species and mark them so they could be tallied. Meanwhile, participants were also carrying cameras to photograph the species so they could be correctly identified and verified before they are added to the 'sighted' species list.


The approximately four-hour-long butterfly count began at 8:00 am and finished at noon – the 'best window' to record butterfly species, as per experts.


Among the rare sightings made include psyche (leptosia nina), red pierrot, Indian red flash and pale palm dart, among others.


While the list is still being compiled, experts said a robust number has been recorded. Historical records stretching centuries show 99 species recorded in NCR. On Sunday, each team recorded an average of 30 species, with the highest tally being close to 50, the TOI report said.
