Family: Lestidae (Spreadwings)
Scientific Name: Lestes praemorsus decipiens
Common Name: Crenulated Spreadwing
Lestes praemorsus decipiens is a member of the Lestidae family. A common name for this species is Crenulated Spreadwing.
This species is uncommon and can be found at large water bodies such as reservoirs and large ponds and wetland marshes. In Singapore, I have seen this species at MacRitchie Reservoir and Bukit Timah Nature Reserves.
The male has powdery light blue thorax with dark spots. The abdomen is dark and shaped like a hockey stick. Aged males are heavily pruinosed.
They typically rest with their wings at an angle away from their bodies and half open. They usually perch on vertical stems of water plants with their abdomen hanging downwards.
