“Dragonflies are excellent macroecological indicators. “We should be able to use them to monitor the changes that are happening in the environment and the climate,” said Halstead. “They’re just a big organism, they survived the extinction of the dinosaurs. Climate change isn’t going to do it. He’s still here.” There are between 50 and 70 species of dragonflies in Saskatchewan. He also adds that one of their main food sources has been in abundance this year due to the drop in numbers. “One of their main food sources is mosquitoes, and there’s definitely an excess of them this year compared to last year,” Halstead said.
