Acisoma panorpoides Rambur, 1842
|Common Names:||Trumpet Tail|
This dragonfly is easily recognised by its uniquely shaped abdomen, which tapers markedly from segments five to seven to form a narrow tip. The male has light blue eyes and body, with dark markings on the thorax and abdomen. The female is similarly shaped and patterned, but with greenish yellow body. In males, the hindwing is 20 to 22 mm in length and the total body leangth ranges from 27 to 29 mm.
Distributed across tropical Asia and Africa.
Commonly seen in disturbed habitats and grassy swamps throughout open country in Singapore, including open areas in Central Catchment and Bukit Timah Nature Reserve and freshwater ponds in Sungei Buloh Wetland Reserve.
Acisoma panorpoides perches inconspicuously. It tends to be more common on short ranked grasses near water bodies. It is mainly associated with eutrophic still waters (D. H. Murphy pers. comm.).
When a female oviposits, the male guards her closely, seldom straying more than 40 cm from her.
