Teneral Wings of  Neurothemis terminata

Wings of a teneral (freshly emerged) male Neurothemis terminata terminata (Ris, 1911)

When teneral, the wing of a male Neurothemis terminate is chocolate color with yellow pterostigma. These wings matured into dark red with red pterostigma.

A common red dragonflies in Sabah. Sees often in drains, ditches and ponds.

There are 3 species of Neurothemis whose males have dark red wings with clear (hyaline) areas at the wing tips.

Females N. terminata  have 2 wing type : The common one have clear wings and the rear one with dark wing.

The 3 species are quite similar in appearance and difficult to identify in the field.

N. terminata is common on Borneo, most of Indonesia, the Philippines but not commonly found in Peninsular Malaysia.
 

To identify : Identify by the small hyaline area at the tips of wings. The hyaline margins are at 90 degree to the wings axis.

Neurothemis terminata is a common species in Borneo.  Even if one see one,  it could be easily mistaken as Neurothemis fluctuans (Fabricius, 1793)  or Neurothemis fulvia (Drury, 1773) which are common in Malaysia.

Only 2 male around the drain when I first saw them on 20th January 2007. No female was seen.   Neurothemis terminata is a timid species. A slice movement of grasses caused by wind is enough to scare it to fly away to another grass.  But they never fly further than a few meters.
This close up took many efforts as Neurothemis are very timid dragonflies that can be scare easily even by a leave movement cause by wind.
