Behavior and Reproduction
The reproductive behavior of E. dione is notably complex. Adult females exhibit a mating system where they may mate with two or more males; in some instances, a female may copulate with two males simultaneously.
As an oviparous species—meaning they lay eggs rather than giving birth to live young—the female typically lays her clutch in July or August. While a standard clutch consists of 3 to 15 eggs, some females have been known to lay as many as 24 eggs.
