What is Street Creatures?  This is the game I run on Twitter every Friday. I’ve
collected all the past quizzes here in one place so you can either relive them, or play
them for the first time.

How does it work?  Provided are four, seemingly unrelated clues, that are all
connected by a wild organism that can be found in a city. Look at the four clues,
do some research, and when you think you’ve figured it out, click on ‘Answer’
to reveal what connects the clues, and how they are connected.

Follow me on Twitter to play #StreetCreatures live every Friday at 9am PST.

The Mecoptera order has been traced back all the way to the Permian period, 250 million years ago. It’s thought they may be the ancestors of butterflies and flies.
