Quick answer
Wood Frogs feed on insects, spiders and slugs, adjusting with season, age, and what is abundant in Forests and woodland near temporary pools. That label is a preferred pattern, not every item an individual might sample.

Wood Frog diet overview
Wood Frogs (Lithobates sylvaticus) are best summarised as Insectivore (insects, spiders, slugs). Anatomy and habitat (Forests and woodland near temporary pools) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How wood frogs find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Wood Frog role in the food web
As consumers in their food web, wood frogs move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild wood frogs. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Behavior and freeze tolerance
Wood frogs are famous for their ability to survive being frozen. In winter, up to two-thirds of the water in their body can turn to ice while their heart and breathing stop, protected by high levels of glucose acting as a natural antifreeze in their cells. When temperatures rise in spring, they thaw and resume activity, often becoming some of the first frogs to breed.
Diet and feeding
Wood frogs are insectivores that forage on the forest floor. They eat insects, spiders, slugs, snails, and worms, catching them with a sticky tongue. Tadpoles graze on algae and plant matter in their breeding pools.
