Lined day gecko (Phelsuma lineata)
|Also known as:||side-striped day gecko, striped day gecko|
|Size||Total length: 100 - 145 mm (2)|
- Like other gecko species, the lined day gecko has specialised toe pads that are capable of impressive adhesion.
- The lined day gecko does not have eyelids, but instead has a transparent covering, known as a ‘spectacle’, over each eye.
- There are three subspecies of the lined day gecko, each with slightly different skin markings.
- The tail of the lined day gecko serves several functions, including being used as a fat store.
- Between 1990 and 1999, the lined day gecko was one of the top ten reptile species imported into the European Union.
The lined day gecko is classified as Least Concern (LC) on the IUCN Red List (1), and is listed on Appendix II of CITES (3).
The lined day gecko (Phelsuma lineata) has soft, green skin on its back and a distinct black band running down the side of its body, bordered on the lower edge by a light-coloured stripe (2) (4).
Three subspecies of the lined day gecko are recognised (1) (5), each differing slightly in their patterning (5). Phelsuma lineata lineata has small red spots on its back. Phelsuma lineata bombetokensis has both large and small red spots on its head and on its back, and also has black spots where the limbs meet the body. The band that runs along the side of its body is greyish in this subspecies, and some individuals may have yellow rings around the eyes. Phelsuma lineata punctulata lacks any red markings but has a back dotted with many black spots (2).
Like other geckos, all subspecies of the lined day gecko have specialised toe pads that are capable of impressive adhesion. The lined day gecko also lacks eyelids and instead has a transparent covering over the eye, called the spectacle. Dust or debris is licked off the spectacle by this species’ long, mobile tongue (4).
The lined day gecko is widely distributed across eastern Madagascar, except the subspecies P. l. bombetokensis, which occurs in western Madagascar (1) (2). The lined day gecko has also been introduced to Réunion, an island in the Indian Ocean (1) (6).
A small lizard, the lined day gecko can be found in palms, bushes and banana plants, either in the rainforest or near villages, and has even been reported inside houses (2).
As its name suggests, the lined day gecko is primarily active during the daylight hours, although it can sometimes be active at night around house lamps that attract the insects on which it feeds (2).
The tail of the lined day gecko has multiple functions. It can be used as an extra ‘hand’ when walking along narrow twigs, it can store fat, and it may also be detached when attacked by a predator (4).
The lined day gecko was one of the top ten reptile species imported into the European Union between 1990 and 1999, with 71 percent of the 45,630 individuals coming from the wild (7). While information appears to be lacking, this would suggest that the lined day gecko may be threatened by over-harvesting from the wild. Like many of Madagascar’s reptiles, the lined day gecko may also be vulnerable to the destruction of the island’s native habitat, although the diversity of habitats in which this species is found shows some degree of adaptability (5).
The lined day gecko is listed on Appendix II of the Convention on International Trade in Endangered Species, meaning that any international trade in this species should be carefully monitored (3). In eastern Madagascar, this species is found in several protected areas, including national parks and special reserves (1).
