Species Name: Indaeschna grubaueri
Male resting beside pond
Members of the family Aeshnidae are the gaints of the Odonata and this is one of the largest of the gaints. This is the second time that I've seen and photographed this species at the very same pond at the edge of a forest reserve near Lahad Datu town. The first time was in 2006 when I saw a male resting on vegetation at the side of the pond, and today I was fortunate enough to see this huge female ovipositing at this pond. Interestingly she was laying her eggs in the moist soil just above the water. This species is also known to lay its eggs in water-filled tree holes and on buttress cavities of large trees.
Female on the wing
Females of I. grubaueri have hindwings that measure up to 68mm while males are thinner and smaller with 59-62mm long hindwings. Both sexes are similarly coloured with bright lime-green markings on the thorax and wide bands on the abdomen.
Female ovipositing on wet soil above water line
This species is said to be widespread in lowland forest in Sundaland and the Philippines.
