The blue-tailed day gecko (Phelsuma cepediana) is a diurnal species of gecko, a lizard in the family Gekkonidae. The species is endemic to the island Mauritius. It typically inhabits warm and humid places and dwells on different trees and bushes.
Additionally, it is noteworthy that the blue-tailed day gecko can change colors and patterns ontogenetically. Depending on the activity, coloration can differ.
The specific name, cepediana, is in honor of French naturalist Bernard Germain de Lacépède.[2]
Phelsuma cepediana is a mid-sized day gecko. It can reach a total length (including tail) of 3.75-5.5″ (9.5-14cm).[3] Female blue tailed geckos are usually smaller in size than the male.
Male blue tailed geckos are typically more vivid than female blue tailed geckos. The male body colour is light green or bluish green. The backs of males have a bright blue colour and are covered with dark red spots and dashes. The males have deep blue tails; this blue color may also be found on their face. Females lack the brilliant blue colour of the males. They have a bright green back and rust-coloured spots. There is always a dorso-lateral stripe present, which may be broken. A red stripe extends from the nostril to the shoulder.[4]
Blue tailed geckos and other reptiles are sensitive to artificial light at night and will change their behaviors as a result of being exposed to this light. These geckos are primarily diurnal, as are most of the geckos in their genus (Phelsuma). It has been found that blue tailed geckos will change their foraging behavior from diurnal to nocturnal in cases where they have artificial light sources at their disposal. Nocturnal activity includes agonistic or aggressive behaviors, courtship, and foraging. When artificial lights are used in nocturnal situations, it alters the amount of time and effort that visual predators will spend foraging.[5]
The Phelsuma cepediana is one of only seven species of the Mascarene species that is still alive. This species is the sole pollinator and seed disperser of a climbing shrub, the Roussea simplex, which is endemic to the mountains of the Mauritius. [6] They can typically be found on trees and bushes that produce fruits, such as coconut palms, banana trees, and papayas. These locations are warm and moist climates, which are preferred by this gecko.
The blue-tailed day gecko inhabits the island Mauritius where it is widely distributed. P. cepediana may also have been introduced to Madagascar where it has been reported a few times, amongst others in the region of Iviloina. These observations have not been confirmed, however. Although these lizards seem to be unable to colonize agricultural areas,[7] they can survive in suburban gardens that are heavily watered and planted as long as these gardens are near trees that produce fruit or flowers throughout the year. [8]
The blue-tailed day gecko feeds on various insects and other invertebrates. It also licks soft, sweet fruit, pollen, and nectar. The flowers of the now critically endangered liana Roussea simplex produce copious amounts of nectar and are pollinated only by the blue-tailed day gecko. The blue-tailed day gecko plays a role by licking up a gelatinous substance secreted by the fruit which contains the minute seeds. It disperses the seeds in its droppings.
This Phelsuma species can be quite aggressive both toward its own and to other Phelsuma species. In captivity, where the females cannot escape, the males sometimes seriously wound the female. In this case, the male and female must be separated.
Lizards can change in color and pattern ontogenetically. Conspicuous tail colors appear only in juveniles and can fade by adulthood. Research has been conducted in order to determine if these tail colors compensate for “an increased activity, level, deflecting imminent attacks to the tail.” Research has suggested that alteration of activities can affect the ontogenetic color and pattern changes. Lizards that are active and forage in habitats that are open tend to increase the probability that they will be attacked by ambush predators. Deflection displays and conspicuous colors can shift attacks to the expendable tail. By doing this, the prey’s overall likelihood of surviving the attack is increased.[9]
Blue tailed geckos lay eggs every 3-4 weeks. They typically lay 2 eggs. [10]
The females will lay their eggs in a location that they feel is safe and protected. The geckos will glue their eggs in order to increase safety. When they are kept at a temperature of 28 degrees Celsius, the eggs take between 40 and 45 days to hatch. When the new borns are measured, they are normally around 40 mm or 1.6 inches.
These geckos frequently will hide amongst dense patches of palm-like Pandanus plants in order to protect themselves from their enemies. The Phelsuma cepediana is preyed on by critically endangered Mauritius kestrel.[11] This bird feeds almost exclusively on Phelsuma geckos, making Phelsuma cepediana one of its main prey. Other birds that are endemic to Mauritius also feed off of Phelsuma geckos. [12]
The 2mm-long ant Technomyrmex albipes that was introduced to Mauritius from the Indo-Pacific area seals the flowers of Roussea with clay to protect mealy bugs. These drink the sap and excrete a sugary urine that is collected by the ants. The ants attack animals that visit the plant, preventing the blue-tailed day gecko from pollinating the flowers and eating from the fruit, and in this way seriously hampering Roussea's reproduction.[13]
Male Phelsuma cepediana are extremely high in demand as pets due to their vibrant coloration, and can cost $100 to $200 each.[14][15] With good care, blue-tailed day geckos may live up to 15 years.[3]

Phelsuma cepediana
Phelsuma cepediana, le Gecko diurne à queue bleue est une espèce de gecko de la famille des Gekkonidae[1]. Elle est aussi appelée Phelsuma cepediana
Cette espèce était endémique de l'île Maurice[1]. Elle a été introduite à Rodrigues.
Sa présence à Madagascar a été signalée à quelques reprises dans le passé, notamment dans la région d'Iviloina. Ces observations n'ont toutefois pas été confirmées[2].
Le gecko diurne à queue bleue se rencontre surtout dans les buissons et des arbres comme les cocotiers, les bananiers, les papayers et l'arbre du voyageur. On le trouve aussi dans les jardins et les maisons dans les zones suburbaines.
En règle générale, il préfère les climats chauds et humides. Or, comme l'a souligné McKeown en 1993, la végétation originelle de Maurice a été largement remplacée par des cultures où ces conditions ne se rencontrent pas et où le reptile ne peut pas vivre.
La température est de 28 à 30 degrés Celsius durant la journée, avec une chute faible durant la nuit. L'hygrométrie est élevée, entre 70 et 90 % selon le moment de la journée.
C'est un gecko diurne et arboricole. Il peut atteindre une longueur totale de 135 mm.
Le corps du mâle est vert clair à bleu vert. Couvert de points et de taches rouge sombre, son dos est d'un bleu intense. Sa queue a un bleu plus profond, d'où le nom commun donné à l'espèce.
De leur côté, les femelles n'ont pas ces couleurs bleues très vives. Il arrive qu'elles aient plutôt le dos d'un vert brillant. Il peut être couvert de points rouge rouille.
En tout cas, mâles et femelles ont toujours une rayure dorso-latérale. Elle est parfois interrompue. Le gecko diurne à queue bleue présente par ailleurs une rayure rouge des narines aux épaules.
Les mâles présentent des pores fémoraux visibles sur l'intérieur des cuisses. Ils se présentent comme une série de petits trous, et génèrent une substance servant à marquer leur territoire.
Les femelles sont un peu plus petites, plus menues et présentent des couleurs plus ternes que les mâles.
Le gecko diurne à queue bleue est insectivore, il aime aussi lécher des fruits à la chair tendre et sucrée, leur nectar et le pollen.
Ce sont des geckos territoriaux, qui peuvent être agressifs au détriment de leurs congénères et des autres phelsumes.
Les femelles pondent dans des endroits protégés. Les œufs y sont collés.
Les œufs incubent durant environ 40 à 45 jours (à une température moyenne de 28 °C, la durée d'incubation pouvant varier selon le climat).
Les jeunes individus mesurent 40 millimètres.
Cette espèce est nommée en l'honneur du zoologiste français comte de Lacépède (1756-1825)[1].
Ces geckos se rencontrent en terrariophilie.

Il geco dalla coda blu (Phelsuma cepediana (Milbert, 1812)) è un piccolo sauro della famiglia Gekkonidae, endemico delle isole Mascarene.[2]
La specie è presente nelle isole di Mauritius e Rodrigues[1]. In passato è stata segnalata sulla costa orientale del Madagascar, ove è stata probabilmente introdotta, ma non ci sono segnalazioni recenti.

Zilastes dienas gekons (Phelsuma cepediana) ir gekonu dzimtas felsuma, kas endēma Maurīcijai.[1]
Vidēja lieluma dienas gekons. Tēviņu garums no aptuveni 12 līdz nepilni 14 cm, kamēr mātīšu garums 8—12 cm.
Tēviņu vēdera daļa gaiši zaļa vai zilgani zaļa, mugura gaiši zila ar tumši sarkaniem plankumiem un svītrām. To aste mirdzoši zila. Mātītēm iztrūkst spoži zilā spozme, mugura tām gaiši zaļa ar rūsganas krāsas plankumiem.
Suga bieži sastopama visā Maurīcijā. Nesen introducēta Rodrigesā. Bija ieviesta arī Madagaskarā, kur tika atzīmēta salas austrumu piekrastē. Taču Madagaskarā nav redzēta vairākus gadus un, acīmredzot, no turienes izzudusi.
Pārsvarā mitinās uz palmām vai palmām līdzīgiem kokiem ar gludiem zariem un ūdeņiem pildītām plaisām, kur, iespējams, rod patvērumu, dēj olas un meklē barību. Visbiežāk apdzīvo ceļotāju palmu (Ravenala madagascariensis).[2] Var būt sastopama arī dārzos un cilvēku mitekļos. Taču šī ķirzaka nespēj dzīvot uz vairuma no lauksaimniecības kultūrām, kuras dominē Maurīcijas ainavā.
Pārtiek no kukaiņiem un citiem bezmugurkaulniekiem, kā arī sulīgiem, saldiem augļiem, putekšņiem, nektāra.[2]
Kopā ar Maurīcijas dienas gekonu nozīmīgi Maurīcijai endēmā auga rūsganās liānas (Roussea simplex) apputeksnētāji. Taču uz šī ļoti retā auga uzturas invazīvās skudras, kas kavē gekonus tos apmeklēt un apputeksnēt.

블루테일 데이 게코(blue-tailed day gecko)라 불리는 파랑꼬리낮도마뱀붙이(Phelsuma cepediana)는 주행성을 띄는 도마뱀붙이류의 일종이다. 모리셔스섬에 고유하며, 따뜻하고 습한 구역에 서식하고 다양한 나무, 덤불에서 지낸다.
종명 cepediana는 프랑스의 박물학자 베르나르 제르맹 드라세페드(:en:Bernard Germain de Lacépède)를 기려 지었다.[2]
파랑꼬리는 꼬리까지 최대 15 cm 에 달하는 중형 낮도마뱀붙이류다 등과 옆구리 사이에는 줄무늬가 있는데, 중간중간 끊어져있기도 하다. 콧구멍에서 어깨까지 붉은 줄무늬가 있다. 수컷의 몸은 연두색, 청록색을 띈다. 수컷의 등은 하늘색을 띄며, 심홍색 점무늬, 짧은 줄무늬로 덮여있다. 수컷의 꼬리는 남색이다. 암컷은 수컷처럼 밝은 파란색을 띄지 않는다. 암컷의 등은 밝은 녹색이며 산화철색 점무늬가 있다.
파랑꼬리는 모리셔스섬에 널리 분포하며, 마다가스카르, 특히 이볼로이나(:en:Parc Ivoloina)에서 몇 번 목격된 적이 있는 걸 봐선 마다가스카르에 도입되었을지도 모른다. 하지만 탐색이 제대로 이루어지지는 않았다.
파랑꼬리는 주로 코코넛야자, 부채파초, 바나나나무, 파파야 따위의 덤불과 나무에서 지낸다. 교외의 정원과 주택에서도 서식한다. 맥커운(McKeown)(1993)은 모리셔스의 원래의 초목지대는 대부분 파랑꼬리가 살지 못하는 농경지로 바뀌었다고 했다.
파랑꼬리는 다양한 곤충 따위의 무척추동물을 먹는다. 부드럽고 달달한 과일, 꽃가루, 꽃꿀도 먹는다. 오늘날 심각한 멸종위기에 처한 덩굴식물 로우세아(:en:Roussea simplex)의 꽃은 막대한 꽃꿀을 분비하며, 오직 파랑꼬리만이 꽃가루를 수분한다. 파랑꼬리는 과일에서 새어나오는, 아주 작은 씨앗이 섞인 젤라틴질의 분비물을 핥아서, 돌아다니는 곳마다 씨앗을 떨구는 역할도 한다. 하지만 크기가 2mm에 불과한 흰발개미(:en:Technomyrmex albipes)가 인도태평양 지역에서 모리셔스에 도입되었는데, 이 개미는 로우세아의 꽃을 진흙으로 뒤덮어서 가루깍지벌레를 보호하는 습성이 있다. 가루깍지벌레는 수액을 빨아서 설탕질의 변을 배설하고, 개미는 이걸 받아먹는다. 개미는 식물에 접근하는 동물을 공격하고, 파랑꼬리가 꽃을 수분하는 걸 막아서, 로우세아의 번식을 심각하게 저해한다.[3]
이 녀석들은 같은 종을 포함한 낮도마뱀붙이류의 다른 개체한테 상당히 공격적일 수도 있다. 사육 시에는 수컷이 때때로 암컷을 심하게 공격할 수 있는데, 암컷이 사육장에서 탈출할 수 없기 때문에, 사람이 암수를 분리해줘야 한다.
암컷은 알을 안전한 곳에서 낳아서 어딘가에 붙인다. 새끼는 온도가 28 °C (82 °F)일 때 40-45 일 후에 부화하며, 신생아는 꼬리까지 40 mm에 이른다.
파랑꼬리는 식물이 무성한 큰 테라리움에서 쌍으로 키워야 하며, 공기 흐름이 충분해야 한다. 온도는 28–30 °C, 습도는 75-100 %를 유지해야 한다. 사육 시에는 귀뚜라미, 시판 과일 사료, 벌집나방(:en:wax moth) 애벌레, 초파리, 밀웜, 집파리를 먹일 수 있다.
