Likely Indianmeal moth (pantry moth)

Stored-food cupboards, pantries, warehouses, and other places containing dry food.

Larvae feed on grains, flour, nuts, dried fruit, seeds, and similar stored foods; adults generally do not feed.

Adults fly mostly at dusk or night and lay eggs on food. Larvae produce silk webbing in infested foods before pupating, often away from the food source.

Harmless to people, but larvae can contaminate and damage stored foods. No notable ecological benefit indoors.
