Naturalist Ed Series: Insects of Osborn Preserve

Willow Leaf Beetle

Fairfield Osborn Preserve
2:00 pm – 5:00 pm

Register for this event

Admission Fees: This is a free event.


Come discover the vast range of insect sizes, shapes, colors, and behaviors! These animals play vital roles in ecosystems, including pollination, decomposition, and serving as food for other animals, and Osborn Preserve's nine plant communities are the home to a wide variety. Insects communicate through pheromones, sounds, and even light. Insects can be beneficial for humans, such as pollinators, or harmful, such as pests that damage crops. 

**This event is part of the Naturalist Ed Series. The event within this series allows participants the option to become Osborn naturalists to address Nature Deficit Disorder.

Leader

Cameron Olson, Graduate Student, Sonoma State University Biology Department

Cameron is conducting research on the population dynamics and interactions of an insect food web in the Eastern Sierra Nevada under his advisor, Dr. Nathan Rank, who has investigated the willow leaf beetle and its natural variation and adaptation for decades.
