Illustration inspired by the Jean de la Fontaine fable "the grasshopper and the ant" using copepod characters, where the grasshopper is described as enjoying the summer, relying on the food available at that time but does not have anything when the winter comes (as the income breeders relies on food availability to fuel their egg production but does not store reserve to survive the winter), while the ant works hard to store reserves during the summer but can rely on them to survive the winter (as the capital breeders store reserve to which allow them to survive the winter and spawn at a time that is disconnected with the timing of the spring bloom, and is beneficial for their offspring).
