Title: “Uncovering the mysteries of insect waste removal: Why and how sharpshooter insects use droplet superpropulsion.”
Speaker: Elio Challita (Harvard SEAS)
Summary: Consuming food and eliminating waste are essential processes for all
living organisms. While the impact of feeding on animal anatomy and
behavior has been extensively researched for over a century, the role of
excretion in shaping and limiting animal behavior remains largely
unexplored. In this presentation, I will explore how tiny sharpshooter
insects, measuring just a few millimeters, efficiently remove their
substantial waste by employing droplet superpropulsion - a process that
allows them to propel droplets at speeds surpassing the underlying
actuator through precise timing. I will also discuss the evolutionary
reasons behind their adoption of this unique droplet ejection mechanism,
drawing upon energetic and scaling principles.
NOTICE: We will be holding hybrid meetings to accommodate COVID-19 precautions and audience members from around the world.
For those able to attend, we
will have an informal dinner at 6:00 pm at Cambridge Common Restaurant
with the speaker, followed by our formal meeting (7:30 - 9:00 pm) in
room MCZ101 of the Museum of Comparative Zoology (there will be signs to
help direct). The meeting will begin with club announcements, followed
by a 60-minute presentation by the invited speaker and Q&A. Membership is open to amateur and professional entomologists. Welcome!
