DAMSELFLIES OF BORNEO
(Zygoptera of Borneo)

A site designed to make available what we know about the distribution, biogeography and biodiversity of Odonata (dragonflies & damselflies) in Borneo Island

Largest and smallest damselflies in Sabah

LARGEST	SMALLEST

Family Calopterygidae Vestalis atropha Body lenghth 56mm	Family Coenagrionidae Agriocnemis femina 白粉細蟌 Body length 22mm

The largest (longest) damselfly is a 56mm body length male Vestalis atropha
The smallest (shortest) damselfly is a male 22mm body length male Agriocnemis femina oryzae

Family Coenagrionidae 細蟌科
Genus Agriocnemis

Agriocnemis are smallest damselflies commonly known as wisps.
They are distributed widely across Africa, South-east Asia, Indonesia, Australia and islands in the Pacific.
The smallest species in our record is Agriocnemis femina oryzae 白粉細蟌 with body length 22mm and wind span of 23mm

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.

Pseudagrion sp HILLZONE
婆羅洲細蟌

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

Most male dragonfly abdomen is often narrower at segment 3, whereas the female abdomen is more robust.

Pseudagrion microcephalum
瘦面細蟌

Pseudagrion microcephalum is a very common in ponds, lakes and drains. The male bright blue with black bands.

Identification Guide to
Vestalis atropha
Common on Borneo forest streams

Female Rhinocypha humeralis

This common Euphaea in Borneo mountain streams still need scientists to ascertain whether ♂ Euphaea subcostalis? or Euphaea subnodalis?

Pseudagrion pilidorsum

First record of Pseudagrion pilidorsum in Borneo. It is common in Philippines.
This species is not listed in both Dr. Orr's books on Borneo.
