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.

The Entomological Society of Ontario's Diversity Statement

The Entomological Society of Ontario (ESO) is committed to encouraging the study of entomology and to increasing public awareness of entomology in Ontario and Canada. Our society values diversity and believes that all members and participants in society events deserve to be treated with dignity, respect, and kindness. The ESO will not tolerate discrimination of any kind, including discrimination based on race, religion, sexual orientation, age, gender identity or expression, national origin, ethnicity, physical or mental difference, or socioeconomic status. All members have roles to play in the promotion of diversity and inclusivity within our society and all of its activities, and within the broader entomological community.

The ESO recognizes and supports all victims of racism. We realize that no words can mend the injustice our black or minority members may face each day, but we stand with you. We hope all ESO members give their support too. Science is for everyone.
