Juveniles stay w/ colony until 3 months old, reaching sexual maturity at 5 months old.
Males extremely territorial often fighting to the death.
Males court females w/ lateral flattening, puffing of throat pouch, & head bobbing. Both sexes head-bob to assert dominance & defend territory.
Females can breed multiple times a year but lay only 1-2 pea-sized eggs per clutch, which are glued to surfaces in secure hidden areas.
Active during the day (diurnal).
Although trade in wild-caught geckos illegal in most areas, many wild-caught geckos sold in pet stores.
Electric blue name refers to male coloration.
Like many geckos, webbed feet great for climbing as well as sticking to surfaces.
They’re highly arboreal not often coming to the ground.

Fun Fact(s):
Many wildlife traffickers intentionally mislabel this species (especially as other Lygodactylus species).
Though they’re not day geckos, sometimes called Electric Blue Day Geckos. They’re closely related to day geckos though.
William’s name honors American herpetologist Ernest Edward Williams.
These are very bold & active geckos.
Sought after due to coloration. Estimated that 32,310-42,610 geckos taken by 1 collecting group between December 2004-July 2009 (around 15% of population).
