Invernut eggs possess a rather unusual ability, they float upon the wind. Due to this unique ability Invernuts can be found living in all areas of Ark. Invernut breeding season is closely monitored by the Science and Research Center in order to give Ark residents a notice to keep their windows closed during the 3-4 days that Invernut eggs float upon the wind.
Invernuts are a rather small insect, only growing to a size of 2 centimeters are most. However these tiny creatures are an extremely important part of keeping Arks many forests and plants healthy. Invernuts eat harmful insects and certain types of moss that can wreak havoc upon even the largest and oldest of trees.
Despite their usefulness and beneficial impact on the environment many Ark residents won't keep Invernuts in their homes. Invernuts leave behind an oily residue that will stain most fabrics.
