It contains photographs of species out of the species found in Sri Lanka up to date. Seasonal forms, dimorphic sexes and other variations of the adult stage are illustrated. Early stages of these butterflies represented by eggs, different instars of larvae, pupae and other related photographs such as the feeding patterns of larvae and leaf shelters of Hesperid butterflies. All the published information on their larval food plants are presented in this web site and it contains photographs of nearly plant species, illustrating their various parts such as leaves, flowers, fruits, barks etc.
Altogether, this web site contains of photographs of various researchers. Distribution maps and seasonal abundance graphs are given for every butterfly species. SLButterflies was a concept of Himesh Jayasinghe, where he started to work on it together with his colleagues, Sarath Rajapakshe and Chamitha de Alwis.
The website was initially designed by Dinesh Kuruppu and Danesh Kuruppu, who were then undergraduates of the University of Moratuwa. Since the butterflies are short living species and Sri Lanka has various habitat types, though it is a little island, distribution patterns, flight periods, larval food plants and migration dispersals have a drastically varied nature. Changes in the regular weather pattern in recent year as an effect of global warming, aforementioned things make further complex, since the ecology of butterflies mainly depends on plant ecology which is directly regulated by rain and drought.
It was understood that collecting data by only a few people will not achieve a reasonable outcome. But these records were not collected in a single place, which is a very hard task to do manually.
Hence it was decided to upgrade SLButterflies as an online data base, so that they can directly enter their field data without a third party. Through the online data sheet, we are collecting following information. Also, many other analysis can be done using this information in the back end for various researches which includes GIS analysis and predictions. For an accurate outcome through an analysis, the data used must be accurate and consistent.
