Leptophis ahaetulla, commonly known as the lora or parrot snake, is a species of medium-sized slender snake of the family Colubridae.[3] It is endemic to Central America and northern South America.[4]
Adults may attain a total length of 172 cm (68 in), which includes a tail 59 cm (23 in) long.[2]
Dorsally, Leptophis ahaetulla is bright green, golden, or bronzy. The keels of the dorsal scales are black or dark brown. The head shields and the dorsal scales may be edged with black. On each side of the head is a black streak which passes through the eye. The upper lip and the belly are white or yellow. The species was thought to be non-venomous,[2] but it is mildly venomous with localized pain, swelling and a feeling "pins and needles" being the symptoms of envenomation. Symptoms disappear after a few hours.
The head is elongated and distinct from the neck. The eye is large with a round pupil. The body is slender, and the tail is long.[2]
The dorsal scales are arranged in 15 rows at mid-body and are strongly keeled except in the first row on each side (the row adjacent to the ventrals), where they are smooth. They are also smooth on the neck and tail.[2]
Ventrals 151-167 are strongly angulate at the sides, the anal plate is divided, and subcaudals 140-173 are divided.[2]
The loreal scale is absent, and the prefrontals extend through the loreal region to contact the upper labials. There are usually 2 postoculars, and the temporals are 1 + 2. There are 8-9 upper labials, of which the 4th & 5th (or 5th & 6th) enter the eye. The anterior chin shields are shorter than the posterior chin shields.[2]
It feeds on lizards, frogs, frog eggs, insects (such as grasshoppers),[5] and small birds and their eggs.[6] They are also known to show cannibalism and feed on other snakes which is a rare behaviour.[7]
