A laboratory formulated blend of food with essential vitamins suitable for wild butterflies, moths and bred butterflies. This easy to use food mix provides a valuable source of nectar for butterflies, moths and other insects at times when there are few flowers available like early spring or late summer, or when habitats have been over-managed and nectar is in short supply. Mix with water and use with Butterfly Biome or in a shallow dish. The special solution has been formulated to ensure the sugars do NOT crystallize in the stomach of the insect, which can be a risk with simple sugar solutions. Unused mixed solution can be stored for up to 7 days in a refrigerator. Weight: 50g.
