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.

Ultrasound
Nerve wings
Meconium
Malpighian tubule silk
Lacewing
Ultrasound:
Lacewings have a nifty tympanal organ near the base of their forewing which twitches in response to ultrasound, likely a defense response to bats. Learn more.
Nerve wing:
Neuroptera, the family of lacewings, antlions, alderflies, snakeflies and scorpionflies translated means – nerve wing.
Meconium:
This is really cool – lacewing larvae have no functioning anus…..so they dispose of it in one final go when they change their skin for the last time. Some species can be identified by the shape of this poo, which is called meconium!
Malpighian tubule silk:
Both lacewings and antlions use their Malpighian tubules to produce silk from their anus, which they use to spin cocoons around themselves to pupate. The only other order to produce silk this way? Coleoptera. Learn more.
