Motti eggs seem to always release a lambent light from their orange patterns. They are popularly kept and used as dim lamps until they hatch. As it gets closer to hatching, an adorable squeaking sound can be heard from inside, which gets louder as time goes by... and potentially more annoying.
Motti eggs should always be kept in dark places. If one is exposed to a lot of light (even just some sunlight on an overcast day), it could seriously harm the growing creature inside. Prolonged exposure will eventually kill it. Those that use one as a lamp will always make sure to keep a box or container handy for keeping it safe in during the day—and the hours of the night when it is not in use.
As young little grubs, Mottis are very playful. They love nothing more than to play all sorts of games with their fellow Mottis. While the baby Motti may not make as much noise as when they were still encased in their egg, they will still squeak a whole lot when having fun or just when they're feeling cheerful in general. However, as a Motti grows into its adult stage, this innate playfulness seems to quickly disappear alongside their vocalizations.
During the autumn season, Motti dominate the skies at night in certain regions. The patterns on their shiny wings glow dimly in the dark, which makes it easy to spot them when their beautiful forms are gracefully fluttering in the dusky skies of Ark. Curiously enough, Mottis seem to have the ability to control just how bright or dull the light emanating from their patterns is. This can be helpful when it comes to either scaring away predators—or just straight up blinding them before escaping—along with keeping themselves hidden when something dangerous approaches.
Interestingly, the Motti does not ever need to eat solid food. They survive purely off energy taken from the moonlight. They do this by "basking" in the light of the moon, similar to a butterfly on a hot summer's day. However, they have to be careful as to how much light they absorb, otherwise it could seriously harm their delicate bodies or kill them. While this isn't a problem during the night, it's mainly the reason why you will never see one of these shining insects during the day. Those who are thinking of owning one as a companion must keep this in mind, for they could possibly die if they are not given a dark place to hide and sleep in during the hours of the day.
