🦋We have modernized! As Canada's oldest entomological society, we want to keep our history while always progressing. Let us know what you think of the new look below 🦋

🐝🪰Build it and they will come! Thanks to Mia for the submission.🌻 Send us a message with your work relating to Ontario insects to be featured on the page🪰 🐝

Have you seen the Monarch this year? Following their migration is a fun way to learn about their behaviours and identify where key areas of habitat exist. You can promote habitat for the Monarch by fostering milkweed and other native foraging plants at your home!

A spotted lanternfly specimen was recently discovered in St. Catharines. While this insect is not established in Ontario, early detection is critical to protecting local farms, vineyards, and trees. If you think you’ve spotted one, take photos, kill it immediately, and report it to the CFIA 🚨🪰

Today we’re celebrating the World Day for Cultural Diversity 🌎🦋 Science is stronger when people from different backgrounds, cultures, and experiences come together to share ideas and learn from one another. Our differences make our community more vibrant, creative, and connected 🐝🌿

Insect feature of the week! I always see these guys hanging out in golden rod, usually feasting on crab spiders and bees! Let us know if you’ve seen the jagged ambush bug around! 🌼🐝🕷️ Thanks for the awesome photo @jesss_bullock 📸 Feel free to DM us your Ontario insect photos to be featured 💬

Today, we stand against homophobia, transphobia, and biphobia, and celebrate the diversity that strengthens both our communities and the scientific world. The ESO is committed to fostering a welcoming, respectful, and inclusive environment for everyone passionate about entomology 🏳️‍⚧️🏳️‍🌈
