Lampshells, including Terebratalia transversa, belong to the phylum Brachiopoda, which translates to arm-foot in Greek. Brachiopods have been around for millions of years, dominating the oceans in the Paleozoic Era (541 to 252 million years ago), but now have a smaller distribution and are known as living fossils as some species have survived for millions of years unchanged.

A real Canadian dragonfly, the Canada darner Aeshna canadensis is native to all ten Canadian provinces. Ranging from a brilliant blue to a rich brown in colour, Canada darner males are usually seen hovering near edges of boggy freshwater habitats, whereas the milder coloured females (who can come in blue, green or yellow) tend to be seen near forested areas or fields. Dragonflies are not just a beautiful sight to be seen. In fact, the presence of dragonflies near a beaver pond or lake – alongside the presence of damselflies and mayflies – is an indicator of a healthy and biodiverse aquatic ecosystem! Not only that, but dragonflies are very sensitive to global climate change – which means that by observing changes in their populations it can indicate changes in climate. Keep an eye out for these important insects on your next hike and see if you are passing by a healthy ecosystem, or one that may be affected strongly by changing temperatures. #Canada150 #Biodiversity150
