It requires Loblolly pines, oak, maple, hickory, and beech trees to provide its food and shelter. Delmarva squirrels occasionally build nests of leaves, but during the summer months prefer to nest in the cavities of these trees. In addition to eating nuts and seeds, the Delmarva also eats tree buds, flowers, fungi, insects, and fruit in the spring and pinecones in the summer and early fall. The Delmarva mates in late winter, with the female giving birth to a litter of 1-4 young around 44 days later. She cares for the young by herself until they are weaned and will fight to protect her nestlings, but will lose some to raccoons, possums, and rat snakes. The Delmarva lives in mature woods of mixed pine and hardwoods, along streams and marshland, or near agricultural land.
