Quebec Wildfire Smoke Causes Deformed Wings in Forest Moths

Quebec’s boreal forest suffered its most devastating wildfire season on record during the summer of 2023, with approximately 4.5 million hectares (11.1 million acres) reduced to ash and charred debris. The scale of the fires, fueled by prolonged drought and record‑high temperatures, has already prompted extensive research into the toxic smoke’s health effects on residents and the broader ecosystem.

While the respiratory and environmental impacts on humans have been documented, scientists have noted a significant gap in understanding how the fires have affected local wildlife, particularly insect populations that play critical roles in pollination, decomposition, and as food sources for higher trophic levels. Early observations suggest that many insect species have experienced habitat loss and altered life cycles, but comprehensive studies are still underway to quantify population declines, shifts in species distribution, and long‑term ecological consequences.

Researchers are now prioritizing field surveys and remote sensing to assess insect biodiversity before, during, and after the fires. The findings will inform conservation strategies and forest management practices aimed at mitigating the broader ecological fallout from Quebec’s unprecedented wildfire season.
