Description
File: Libellulidae - Orthetrum testaceum.webm
Orthetrum testaceum can reach a body length of about {{cvt|43|-|48|mm}}, with a hindwing of {{cvt|34|-|38|mm}} (in males). In these large dragonflies the thorax of adult males is orange-brown, with a vermilion red abdomen. The eyes are light brownish. The wings are smoky transparent, with an amber patch at the base. In adult females and in recently emerged males the body is olive-green to brown in colour with black markings and a clear base of the hindwings.
These dragonflies are rather similar to Orthetrum chrysis, but O. testaceum is more reddish, while O. chrysis has a reddish brown thorax.[https://lkcnhm.nus.edu.sg/dna/organisms/details/751 The DNA of Singapore] Lee Kong Chian Natural History MuseumTang, H.
