Sneaky bug(ger)s

What would you do if you were a tiny insect and prey to those swooping swirling creatures of the night that can track you by sonar?

Obvious isn't it?

You learn to jam the sonar.

Bertholdia trigona, a moth native to the Arizona desert, emits ultrasonic clicks at a rate of 4,500 times per second to blur bats' acoustic vision
Next question.

What species are moving amongst us now that have the same jamming capabilities for our senses... and how would we ever know?
