Mothman eggs are laid in specific locations on the ground by the Mothman but are not known to ever hatch. Mothman eggs can be collected and sold to vendors. Alternatively, they can be cooked into Mothman egg omelette for food.
Mothman eggs can be found in Point Pleasant on the ground near the Mothman statue and directly west of the statue at the shrine next to the river.
As of the release of Wastelanders, Mothman eggs can be found in several other locations:
- Clancy Manor, first floor near the fireplace, second floor in the sleeping bag room. Ten patches total.
- Moth-Home, five patches can be found inside the shrine.
- Sacrament, five patches around the shrines in the walled encampment.
- Mothman cultists used a "holy oil" made from these eggs to bless their effigies.
