IDENTIFICATION CHARTS OF BORNEO DAMSELFLIES
The following are some color image illustrations of common damselflies in Borneo, Including diagrams of Damselfly  Morphology.
Including some new records found recent years that require further scientific projects.

This is one of the several new records  found in Sabah. Distribution is uncertain. More scientific research is required.



ABDOMEN DIFFERENT BETWEEN MALE AND FEMALE DRAGONFLIES
