I posted an entry on 12 February 2008 about one dragonfly stamp (Trithemis festiva). You may click here to view the entry.
After looking carefully at the illustration of the dragonfly image in the stamp (see stamp below). I feel that the drawing/illustration on the stamp has a small error. If you pay attention to the wing tips of the dragonfly in stamp illustration, you may notice the wing tips are tinted. Actually, Trithemis festiva does not have tinted wing tips. In other words, tinted wing tip is not a characteristic of Trithemis festiva.
On the other hand, Indothemis limbata looks close to Trithemis festiva. However, both could be readily distinguished if one pays enough attention. Trithemis festiva has orange/yellow strips on the dorsal of abdomen (as illustrated in the stamp), and Indothemis limbata lacks of this characteristic. Nevertheless, Indothemis limbata has tinted wing tips, and Trithemis festiva does not have tinted wing tips. So, the illustration in the stamp showing tinted wing tips is an error.
