Despite primarily being defined as carnivores, what supplementary food source does Cheiracanthium inclusum incorporate for fitness gains?

Answer

Plant matter, specifically nectar

Although the yellow sac spider is fundamentally classified as a carnivore because its primary energy source comes from consuming animals, a crucial aspect of its survival strategy involves supplementing its diet with plant matter. The specific source identified is nectar. This supplementary intake is more than incidental; it offers tangible physiological benefits, directly translating to increased fitness by improving survival rates, fostering better growth, and crucially, enhancing fecundity (reproductive output). This ability to switch partially to readily available carbohydrates provides a significant adaptive advantage, especially during periods where insect prey is difficult to locate.
