Insect Conservation and Diversity, Volume 19, Issue 3, Page 634-646, May 2026.Despite severe habitat loss, insect species richness, seasonal fluctuations in richness and temporal β‐diversity did not differ significantly among forests adjacent to the mudflow and reference sites. We found higher wet‐season species richness for ants, bees, butterflies and dung beetles, while termites showed no seasonal change; β‐diversity was ...
