Woodchucks are vegetarians – they feed on a variety of grasses and chickweeds, plantains, clover, cherries, raspberries, blackberries, and other fruits along with many varieties of cultivated flowers and plants. These creatures love fresh produce too. They also eat June bugs, grasshoppers, and other large insects.
Woodchucks have a lifespan of 5 to 6 years. They do not mate until their second year. Males and females breed in March or April. After this, they have no further contact with the female leaving them to raise the young alone.
