Habitat type influences the choice of sampling method in a butterfly survey

Urban landscapes can support the diversity of beneficial organisms like butterflies if they are well managed. Proper management may vary with different habitat types which may involve habitat specific sampling and conservation approach. This study investigated butterfly diversity in different habitat types in an urban landscape. Different sampling methods were compared across the varying habitat types. Forty-two species of butterflies were reported in the study area with an abundance of 720 butterflies. There was a significant difference in the mean abundance and species richness of butterflies across sites and sampling methods. Furthermore, sweep netting method had the highest mean abundance and species richness of butterflies sampled across study sites. Species composition of butterflies also varied significantly across study sites. While sweep netting is a preferred sampling method, there is need to give consideration to the habitat type to be sampled when making the choice of sampling method in butterfly surveys.
