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.
The larvae of some species of caddisflies are shredders, meaning they shred up plants or animal debris into smaller pieces which they consume.
The order of caddisflies is Trichoptera, from the Greek ‘thrix’ meaning hair and ‘pteron’ meaning wing. True to their name the wings of adult caddisflies are covered in small hairs.
Artist Hubert Duprat wanted to know if caddisfly larvae, who construct their temporary homes out of rock, wood and other debris, would make their cases out of precious materials. They did.
Many species of caddisfly larvae spin silk that they use to spin portable cases by attaching rocks or other detritus together. Others use it to anchor themselves to rocks to avoid being swept away by currents.
