Today is National Day for Truth and Reconciliation 🧡

Each day, we honor the children who never came home, the survivors of residential schools, and their families and communities.

Reflection, respect, and ongoing learning are essential steps toward reconciliation.

Check out this assassin bug nymph (Reduvius personatus) for bug community day! Nymphs secrete a sticky substance that collects dirt and dust to create a layer of camouflage. 😶‍🌫️

HAPPY BUG COMMUNITY DAY!! 🦟🦟🦟

Thank you @sierra.simioni for these photos!! 📸

Spotted a squad of striped bark lice (🪲 Graphopsocus cruciatus)—also known as tree cattle! 🌳✨

These tiny insects may look like pests, but they’re actually beneficial decomposers 🌱

Oecanthus fultoni 🦗

Also called the snowy tree cricket or thermometer cricket, is a great example of how cool (and useful) insect behavior can be 🤯

Its chirp rate changes with the temperature 🌡️, so you can estimate the temperature just by listening👂

Time for a game- Spot the Katydid!🔎

🦗 The Fork-tailed Bush Katydid gets its name from the male’s tail, which looks like a tiny green horseshoe—perfect for lucky bug spotting! This insect is found across Southern Canada.

Happy Bug Community Day People!!!🐝

The species you are looking at today is the Trogus pennator (no common name) 🤯

This ichneumon wasp plays an important ecological role as a parasitoid of swallowtail butterfly caterpillars 🦋🐛

Thank you @matteo.girardo for the awesome photo!! 📸

Instead of Old Macdonald's farm, its the Ants farm, and on this farm they have aphids! 👨‍🌾🐜

Several species of ants and aphids have a symbiotic relationship where the ants provide protection and aphids produce honeydew for the ants to eat 💧

Check out this Northern crescent butterfly for Bug Community Day!

Do you think a butterfly landing on you a sign of good luck, salty skin, or something else? Share your thoughts in the comments!

Meet the firefly larva! In Ontario, nearly all firefly species glow in their larval stage 🔥🪰

As adults, fireflies flash again for courtship communication! Each species has its own unique pattern and slightly different flashing colours 💡❤️

Reducing light pollution helps keep fireflies in your yard!

Mayfly season is here in Ontario! 🪰🌊

These insects spend up to 3 years underwater as nymphs 🤿

After molting into winged adults, they only live from a few hours to a couple of days.🧬⏳

Their mass emergence feeds fish 🎣, birds 🐦, and bats 🦇, and signals clean, healthy freshwater ecosystems! 💧🌱

Sadly, we don't have a national insect, what species would you suggest? 🦋
