Welcome to the Entomological Society of Ontario
The Entomological Society of Ontario (ESO) is an active society, dedicated to furthering entomology through annual meetings and publications. Over the past 149 years, it has served as an association of persons interested in the science of entomology. Today, as always, members of the Society have varied entomological interests; physiology, taxonomy, ecology and pest management. Although founded by amateurs, whose active participation is encouraged today the majority of the Society’s members are professionals, sharing their interests and expertise while working either in Provincial or Federal governments, industry or universities within Ontario as well as other parts of Canada and the world.

Guelph Bug Day!
Sunday August 26, 2018
University of Guelph Arboretum Center
Guelph Bug Day is a fun, free, educational event for community members of all ages. Our goal is to cultivate a fascination for the very cool, very small world of insects! Come get up close and personal with our live specimens, take one (or two, or three!) guided bug-catching hikes in the expansive and beautiful grounds at the University of Guelph Arboretum, try tasty insect cuisine, put your imagination to the test with insect drawing contests, and explore the variety of buggy vendors that Guelph has to offer. Rain or shine, bring your adventuring spirit and prepare to be amazed.
