5th instar: full eyespots displayed

Here are some updated shots of the Papilio canadensis caterpillars. They are now getting much larger - and their eyespots are in their full glory!

Below is a rare shot of a caterpillar that recently moulted (i.e., shed its skin). You can see the shedding beside it in the photo. Remember that moulting means that the caterpillar has now passed into the next instar!
