This “bug” was discovered on the sidewalk in downtown Burlington, Ontario, Canada (off Lake Ontario). It had a head bobbing motion, and what looks like eyes on the sides of its head (fake illusion eyes?). It “sticks” to whatever it’s on very well and it’s mouth looked like a suction cup. Overall it looks cartoonish, almost right out of A Bugs Life. What is this?

Dear Curious bugaphobe,
This is one of the Tiger Swallowtail Caterpillars, and there are many similar species that are regionally distinct, but that look quite similar physically. Considering your location, we are guessing this is most likely a Canadian Tiger Swallowtail, Papilio canadensis, which you can find pictured on BugGuide.
