There are both diurnal and nocturnal geckos - day-active and night-active. I´ve come across both. Day geckos mostly sit on walls and rocks basking in the sun and catching insects; night geckos invade the house while you´re sleeping and wake you up with loud mating calls!
If you´re looking for a pet gecko, get a day-active one ;)
they sleep at day
I believe that geckos have a very similar sleeping patterns to cats. Some can sleep at night some can sleep during the day, some seem to always sleep and some seem to never sleep. I find that geckos are use to being handled at certain times, so if you play with your gecko during the day that is when the gecko will be routinely active.
Yes, geckos are nocturnal but you can still see them awake in the daytime. Example is a leopard gecko, rarely you would see them up in the day. Although most gecko species are nocturnal, doing their daily activities at night, some species of gecko are diurnal. This means that they are active during the day. These species of geckos are called Phelsuma (day geckos).
The simple answer is it depends. If they are diurnal - they sleep at night, if they are nocturnal (eg. crested gecko) they will sleep through the day. It all depends on the species of Gecko.
they are typically less active during the day
They are mostly active at night and rest during the day.
Animals that are active during the day are referred to as being diurnal.
Not all but most gecko species are nocturnal. As a gecko becomes more comfortable in its terrarium/habitat it may tend to move around more during the days. Species of day gecko make great display animals as they are active during the day but tend to be a tad shy and scittish
Day geckos are native to Madagascar and surrounding inlets. There are many species of day gecko coming from the "phesulma" family of geckos.
Depending on the geckos specie will determine the amount of light they receive each day. A specie of Phesulma (day geckos) can be seen basking in direct sunlight for up to 12 hours a day. Most nocturnal species of gecko will seek shelter during the days and are active at night. All gecko specie do require light every day, they must be on a light cycle. As hobbyist's, we are trying to replicate their natural environment and in the wild, the sun will still shine from 8-14Hours daily (depending on location)
They are active during the day.
they re active during the day
Most geckos are nocturnal. So, during the day, most tend to darken their color. Some geckos, like the Crested Gecko, has a brighter more beautiful color at night.
