Little is known about the lepusa as yet. Their short lifespan (averaging roughly 17 years) and their penchant for excavation compounds the difficulties of gathering reliable data. Living in packs of 70 to 100 individuals, with an average litter of five to eight individuals every two years, unchecked population growth often results in a maze of underground tunnels that undermine soil productivity. In recent years, lepusa migrations have, unfortunately, threatened local farming efforts. As natural herbivores that live off roots and grubs, lepusa have found newly introduced off-world grains to be a particular delicacy. Few farmers, however, are willing to share their plantings with their new neighbors. In fact, many lepusa are killed as vermin by angry planters.

Adding to the controversy, recent studies have suggested lepusa are capable of manufacturing their own tools. These findings are hotly debated by farmers, who would lose out if the lepusa become classified as a protected species. While the debate continues a temporary injunction against killing lepusa has been imposed.
