Which species has a mating season that lasts until early July?

The Virginia Opossum has a mating season that typically lasts until early July, making it notable for its relatively extended breeding period compared to other species. Opossums are unique among North American marsupials and exhibit a mating cycle that can extend from late winter through mid-summer, which is not as common in many other mammals.

In contrast, the mating seasons for the other species mentioned are generally shorter or occur at different times of the year. For instance, woodchucks primarily breed in the spring, while both the Eastern Newt and Blue-spotted Salamander have mating seasons that occur primarily in the spring months. The timing of the Virginia Opossum's mating season aligns with its adaptive strategies, allowing for potentially multiple litters in a single season depending on environmental conditions.
