Euproserpinus wiesti
Scientists learned that certain moths are able to escape predatory bats by making sudden evasive movements when they hear the sonar of an approaching bat. Later research disclosed that Euproserpinus wiesti, or the prairie sphinx moth, is able not only to dodge the bats but actually jam the bat’s sonar with extremely rapid ultrasonic clicks. The moths create a sort of blanket of sound around themselves, so the bats cannot sense them clearly in the cloud of noise. The moths are reported to stridulate by rubbing their genital parts together.
