The study deals with population diversity and seasonal variation of insectsin Sandspit mangrove forest dominated by grey mangrove Avicennia marina. In order toexamine the diversity and seasonal variations monthly data were collected fromNovember, 2007 to October, 2008. A total of 26 species of insects were recorded, mostof the species belonging to order Diptera. The highest diversity (H') 1.936 and richness(d1) 2.309 of insects were found in October while maximum value of evenness 1 wascalculated in September. The highest value of dominance (D) 0.851 was recorded inMarch. The result indicates that physical structure of mangrove vegetation facilitates thehabitation of insect fauna, canopy shade having an important function in providing coolerand wetter surface substrate at Sandspit area.
