Diagram of animal visitors observed visiting plant parts where the studied external secretory structures are found (nectary disc and staminal hairs at flowers, calycinal glands at calyxes, petiolar nectaries at petioles, and foliar glands at leaves). Visitors were classified as: herbivore (consumes plant organs, such as leaves or flowers), potential protector (consumes exudates and may protect plant from herbivores), exudate consumer (consumes exudates but likely does not offer protection from herbivores), or potential pollinator (visits flowers and possibly pollinates them). Most visitors fell under a single category, with the exception of cockroaches (Blattodea), which were classified as both exudate consumers and potential pollinators. Note: Dashed lines connecting visitor names to plant parts only indicate that visits were observed, they do not indicate visitation frequency.
