Question: Why give normal food to a butterfly that is not yet age 5?
Answer:
A butterfly between ages 0 and 5 cannot reproduce, so giving premium food is unnecessary and wastes your money. Providing normal food to butterflies that are not yet adults is the best way to save your budget. Once they reach age 5 and are paired, you can then give them premium food.
Keep in mind that premium food is an option to help butterflies increase love faster, resulting in more babies during their life cycle. However, you are not required to feed your butterfly premium food. A butterfly eating normal food will still go into love, but the process will take longer.
For example, with normal food, a butterfly needs 5 days of gestation to make a baby, while a butterfly eating premium food only needs 2.5 days for the same process.
