When your lab dresses up for Halloween as the many versions of their supervisor. It was like looking in a mirror- very spooky! 👻🎃

This big chinese mantis (Tenodera sinensis) came to visit our quad on campus today, perhaps in search of a mate. It didn't find a mate but it did find me, and some curious undergrads who exclaimed "WOW, I didn't know we had those in Canada". In fact, they arrived in North America 120 years ago!
