Mantises are great! They are very interesting to look at, they are quite easy to care for and you can even pick them up gently from time to time.
Sometimes the model was a bit too friendly.
Another easy to care for, though far less active insect, is the stick insect.
It generally behaves like its namesake, though it can move at a respectable pace.
They've got really tiny cute eyes too.
Teaching about bugs!
