Added 4 April 2007. Last updated 16 June 2022: updated Introduction and Bibliography, added D. abbreviatus , D. beccarii, D. boschmai, D. formosus, D. indochinensis, D. iskandari, D. spilonotus, D. sumatranus, D. supriatnai, D. timoriensis and D. walkeri, and updated D. affinis, D. blanfordi, D. cornutus, D. cristatellus, D. fimbriatus, and D. volans.
Many people will have heard of flying lizards: this is the genus most commonly referred to as such. In fact Draco species do not have the capability of true flight, but instead use their foldable wings (formed by movable ribs with a membrane of skin stretched between them) to glide from one tree to another.
These are small lizards, being usually no more than 9-10 cm snout-vent length, with the tail being roughly the same again. Boulenger gives the characteristics of the genus as follow: body depressed, with a large lateral wing-like membrane, supported by the a much-produced five or six posterior ribs, folding like a fan.; a gular appendage, and a lateral smaller one on each side; tympanum distinct or covered with scales; tail long; no femoral or preanal pores. The shape and colour of the gular sac can be helpful in identification of the individual species. Overall coloration varies not only between species but between the sexes. Manthey and Schuster caution that some of the descriptions given are contradictory and that some Draco species are quite difficult to identify.
Given their small size, coloration and fascinating body structure, one might think these might be lizards in demand as pets. Unfortunately their apparent desirability is completely nullified by their diet, which consists almost wholly of ants and termites, both of which they consume in large numbers. As with other formivorous (ant-eating) species, this makes their satisfactory captivity very difficult, especially as neither ants nor termites are desirable commensals in a human dwelling. Even zoos find these lizards hard, if not impossible, to maintain. If you want a flying lizard, one of the Ptychozoon geckos is by far easier.
Most people will never see Draco in captivity, but such is their range in SE Asia that they may well be encountered in the wild.

One thing that has concerned me is finding at least one site on the Net that suggests Draco species can be kept alive by feeding them mealworms and crickets. The general consensus is that this is impossible: ant-eating lizards such as these tend to have this diet more or less exclusively, and to fade fast if this requirement is not met. If anyone has proof to the contrary, especially if they can cite a reputable literature source, I would be interested to hear from them.
