Project Noah Fun Fact: Bertholdia trigona

Happy National Moth Week 2017!

In honor of this year’s focus on tiger moths, our partner, citizen science website Project Noah, will be featuring a fun fact about the tiger moths (Erebidae: Arctiinae) during National Moth Week.

From Project Noah:

Moths are constantly under the threat of predation by bats, and have evolved defenses to avoid this. Some tiger moths, such as this beautiful Bertholdia trigona, can emit clicking sounds to jam the sonar of bats, allowing them to disappear long enough to escape predation (Corcoran et al. 2011). The clicks are emitted from structures called tymbal organs.
