Draco volans, or the
Flying Dragon, is a member of the genus of gliding lizards
Draco.
It can spread out folds of skin attached to its movable ribs to form
"wings" that it uses to glide from tree to tree over distances upwards
of 8 metres (26 ft); however, like all modern reptiles, it lacks the
ability to sustain powered flight, and is capable only of gliding. Its
wings are brightly coloured with orange, red and blue spots and stripes,
and they provide
camouflage when folded. The flying dragon can reach up to 19–23 centimetres (7.5–9.1 in) in length. It feeds on
arboreal ants and
termites.

Taxonomy
They are classified as dragons in the phylum Chordata, subphylum Vertebrata, class Reptilia, order Squamata, family
Agamidae.
Distribution
Common Gliding Lizards (
D. sumatranus) and Spotted Gliding Lizards (
Draco maculatus) are common in open and disturbed areas; Five-banded Gliding Lizards (
D. quinquefasciatus) are usually found in dense forest with relatively small, closely spaced trees; Giant Gliding Lizards (
D. maximus) are somewhat restricted to riparian areas; the smaller Yellow-bearded Gliding Lizards (
D. haematopogon) and larger Blanford's Gilding Lizard (
Draco blanfordi)
occur at higher elevations than most other species; and the
Black-bearded Gliding Lizards and the larger Dusky Gliding Lizards (
D. formosus) are habitat generalists in lowland forests.

Description
Flying Dragons are brown with bluish coloration on the undersides of
their wings and a yellow colored dewlap. Females tend to have bluish
dewlaps and yellow coloring on the wings' undersides. Their heads are
blunted and fairly short, and each leg has five clawed toes. Flying
Dragons have low, long bodies. They have flaps of skin along the ribs,
which can be extended into "wings" by the lizard elongating its ribs.
They have a dewlap, or gular flap, which can also be extended.
Generally, Flying Dragons grow to a little less than 12 inches in
length. Although females are usually larger than males, their dewlaps
are a bit smaller.
Size
This lizard can get to about 20 cm long. Its wingspan is usually 3/4 of its body length.
Breeding
During breeding season the female flying dragon will venture down to the forest floor and bury her 1-4
eggs in the soil. Its range is the Philippines to Malaysia and Indonesia.
Behavior
The Flying Dragons are native to the southwest tropical forests of
Asia and India, including Borneo and the Philippine Islands. In the
wild, the Flying Dragon will generally claim a territory. Usually, males
will mark two or three trees as their own, and one to three female
Flying Dragons will live in each tree. When the male Flying Dragon meets
another animal, he may extend his dewlap partially or fully, extend his
wings partially or fully, perform a combination of dewlap or wing
extension, or bob his body up and down. If he meets a female, he may
circle her. Extending the wings and dewlap makes the Flying Dragon
appear larger, and he will usually exhibit such behavior if he feels
threatened. Flying Dragons eat insects. They catch such prey by sitting
under a tree until an insect passes by, and then they consume it. They
have short sticky tongues that they use to eat ants and termites.
Gliding
In order to move from one place to another, Flying Dragons will
spread the skin flaps along their abdomens and glide out of trees or
from other high areas. They never glide when it is raining or when it is
windy. When the Flying Dragon is about to take off, it will point its
head toward the ground.
