Spongy Moths & Cicadas: Facts & Fallacies In-Person

Dr. Frederic Miller of the Morton Arboretum and Riverside Village Forester Michael Collins will explain why these fascinating insects are so destructive to trees and plants and what can be done to minimize the damage they cause.

The program will address two threats to Riverside trees and plant life; the ongoing danger of the Spongy Moth and the return of the 17-year cicada brood this summer. Spongy Moths pose a threat to trees and plants during their caterpillar stage. The caterpillars feed voraciously on leaves, defoliating trees and weakening them. In severe infestations, they can even kill their host tree. While adult cicadas don't directly harm trees and plants by feeding on them, their egg-laying behavior can damage young twigs and branches. Female cicadas slit the bark of woody plants to deposit their eggs, which can cause breaking, wilting or dieback in affected limbs. As a scientist, presenter Dr. Frederic Miller writes, "2024 will be a unique year as the 17-year periodical cicada will be emerging throughout northern Illinois. This is a short, but very interesting entomological event worth enjoying. We will discuss the fascinating biology and feeding habits of the periodical cicada, egg laying preferences, susceptible woody plant species, and potential for damage to young trees, whips, and seedlings. Practical management methods will be presented for homeowners."

Co-sponsored by FLOS and the Riverside Landscape Advisory Commission
