Overview

Randomized trial investigates butterfly diversity in human-modified suburban areas, suggesting conservation strategies.

Key Points

  • This study aims to understand how butterfly diversity varies in suburban habitats affected by urbanization.
  • Conducted butterfly surveys using a standardized plot sampling method over eleven days.
  • Recorded species composition and distribution across four suburban ecosystems in Sri Lanka.
  • Analyzed family-level dominance and diversity indices including Shannon-Wiener and Simpson’s index.
  • 51 butterfly species from five families identified, with Pieridae dominating home gardens and Nymphalidae in coconut estates.
  • Home garden habitats showed the highest diversity (Shannon-Wiener index H′=2.95); species richness peaked in the coconut estate (32 species).
  • Butterflies preferred large home gardens, highlighting the need for conservation and public awareness strategies.
