Abstract

Present study was conducted to study seasonal abundance and distribution of dragonflies in upper Siran valley district Mansehra Pakistan. To collect data, eleven localities were visited for three consecutive years (2016-2018). Results come up with a sum of 300 specimens identified under three families, eight genera and twenty species. Highest seasonal abundance recorded during summer and spring were 80.67% and 13.33% respectively while minimum 6.00% was recorded during early autumn. Dominant species observed were, Orthetrum chrysis (14.00%), followed by O. gluacum (12.00%), Palpoleura sexmaculata sexmaculata (11.33%) and O. cancellatum cancellatum (8.00%). However the highest population of dragonflies was found in Munda Gucha with a percentage of 11.33 followed by Jabbar (11.00%) and Sachan (9.67%). The lowest populations were recorded in Suham (6.00%), Dadar (7.67%) and Jabori (7.67%). The surveyed valley showed diverse Anisopterous fauna and thus further extensive surveys are recommended that can come up with more important species from the area. Resumo O presente estudo foi realizado para verificar a abundância sazonal e a distribuição de libélulas no vale superior de Siran, distrito de Mansehra, Paquistão. Para a coleta de dados, 11 localidades foram visitadas por três anos consecutivos (2016-2018). Os resultados apresentaram uma soma de 300 espécimes identificados em três famílias, 8 gêneros e 20 espécies. A maior abundância sazonal registrada durante o verão e a primavera foi de 80,67% e 13,33%, respectivamente, enquanto o mínimo de 6% foi registrado no início do outono. As espécies dominantes observadas foram Orthetrum chrysis (14%), seguido por O. gluacum (12%), Palpoleura sexmaculata sexmaculata (11,33%) e O. cancellatum cancellatum (8%). No entanto, a maior população de libélulas foi encontrada em Munda Gucha (11,33%), seguida por Jabbar (11%) e Sachan (9,67%). As populações mais baixas foram registradas em Suham (6%), Dadar (7,67%) e Jabori (7,67%). O vale pesquisado mostrou fauna Anisopterous diversificada, e, portanto, recomenda-se a realização de mais pesquisas que possam apresentar mais espécies importantes da área.
