Anax panybeus is very like A. guttatus, except that there is a distinct T' on the dorsal part of the frons, , and the third abdominal segment is a little more constricted and distinctly longer. The male appendages also differ slightly. It is found in all the same situations as Anax guttatus but is everywhere considerably rarer and more crepuscular in its habits.

Crepuscular = A term used to describe animals that are primarily active during the twilight. The word ultimately derives from the Latin word crepusculum, meaning "twilight".

Anax panybeus. heavy bodied; S2 and base of S3 mainly blue; strong spotting on ab. Open habitats with standing water, including drains, ponds, swamps and lakes; common in disturbed habitats and along the landward margin of mangroves, where it may breed in slightly brackish water.

Widespread in the Indo-Australian tropics and southern China and  Asia. This species is large robust insects with a heavy thorax and broad hind wings.

In males as well as females the anal angle of the hind wing is rounded. Older specimens often develop quite a dark brown tint to the wings, concentrated especially near the base of the hind wing.

Anax panybeus frequents almost any deep standing water habitat in open country. Males in particular are active all the day and may be seen hawking up and down drains, across natural lakes, or around dams. The females tend to oviposit in the afternoon, often after dusk. Eggs are inserted into suitable soft living plant tissue, the underside of lily pads being a common choice.

They are swift and powerful fliers

Living on still waters under the altitude of 1000 meters. The males' compound eyes are green. A dark brown "H" mark lies flat on the forehead. Chests are green, wings transparent, but elytrons are brown, with yellowish orange spot. The females' hind wings are light brown in the center.
