Cover: Acoustic caterpillars? One does not think of caterpillars as being especially noisy, but research by Brown, Boettner and Yack (see article on p. 993 ) demonstrates that several species of silk- and hawkmoth caterpillars produce audible clicking sounds. The silkmoth caterpillar portrayed on the cover, Antheraea polyphemus, clicks its mandibles following an attack by a live or simulated predator. Sound production typically precedes or accompanies defensive regurgitation. The authors provide evidence to support the hypothesis that caterpillar clicking functions as an acoustic aposematic signal to warn a predator of the impending regurgitant defense.

In the field: an interview with Martha Muñoz

Martha Muñoz is an Assistant Professor at Yale University, investigating the evolutionary biology of anole lizards and lungless salamanders. In our new Conversation, she talks about her fieldwork in Indonesia, Costa Rica, the Dominican Republic and the Appalachian Mountains, including a death-defying dash to the top of a mountain through an approaching hurricane.
Graham Scott in conversation with Big Biology

Graham Scott talks to Big Biology about the oxygen cascade in mice living on mountaintops, extreme environments for such small organisms. In this JEB-sponsored episode, they discuss the concept of symmorphosis and the evolution of the oxygen cascade.
Trap-jaw ants coordinate tendon and exoskeleton for perfect mandible arc
-AntJaws.png?versionId=3942)
Trap-jaw ants run the risk of tearing themselves apart when they fire off their mandibles, but Greg Sutton & co have discovered that the ants simultaneously push and pull the mandibles using energy stored in a head tendon and their exoskeleton to drive the jaws in a perfect arc.
Hearing without a tympanic ear
-Review.png?versionId=3942)
In their Review, Grace Capshaw, Jakob Christensen-Dalsgaard and Catherine Carr explore the mechanisms of hearing in extant atympanate vertebrates and the implications for the early evolution of tympanate hearing.
