Mothman eggs are the presumed eggs of a Mothman but their exact origins are unknown. They are typically found in clusters around areas related to the Mothman and the Cult of the Mothman. They can be consumed raw to satisfy a small amount of hunger with a very high dose of radiation and a high disease chance, or cooked for additional benefits.
- Point Pleasant, on the ground near the Mothman statue and directly west of the statue at the shrine next to the Silver Bridge.
- Clancy Manor, first floor near the fireplace, second floor in the sleeping bag room. Ten clusters in total.
- Ingram Mansion, six clusters inside the house.
- Moth-Home, five clusters can be found inside the shrine.
- Sacrament, five clusters around the shrines in the walled encampment.
- Kanawha County Cemetery, three clusters found in a shed to the left of the road.
- Mothman cultists used a "holy oil" made from these eggs to bless their effigies.
- Prior to patch 18.104.22.168, the Green Thumb perk allowed double the Mothman eggs to be collected from each cluster.
- Unlike other eggs, Mothman eggs are not classified as meat, therefore the Carnivore mutation has no effect. Despite being harvested in a manner similar to flowers, fruits, and vegetables, they aren't classified as such either and therefore the Herbivore mutation also has no effect.
