Abstract

We studied the potential pollinators of four Chloraea orchid species that grow sympatrically in Central- South Chile. We recorded potential pollinator visits, and evaluated capsule formation after 30 days. Results revealed Coleoptera and Hymenoptera species as potential pollinators, with no specific preference for any orchid species. Many visited flowers aborted, leading to low capsule formation, especially in C. lamellata. These findings enhance our understanding of Chilean orchid biology, aiding in their conservation efforts.
