Among insects, tympanal ears evolved at least 18 times, resulting in a diversity of auditory
systems. Insects use their ears in different behavioural contexts, mainly intraspecific …

Bushcrickets (katydids) rely on only 20 to 120 sensory units located in their forelegs to sense
sound. Situated in tiny hearing organs less than 1 mm long (40× shorter than the human …

Insects have evolved complex receptor organs for the major sensory modalities. For the
sense of hearing, the tympanal organ of Tettigoniidae (bush crickets or katydids) shows …

Acoustic communication is one of the most well-known behavioural traits of the Orthoptera.
Orthopteran insects and the sounds they produce are both extremely diverse, and species …

In orthopteran insects, a complex tibial organ has evolved to detect substrate vibrations
and/or airborne sound. Species of New Zealand weta (Anostostomatidae) with tympanal …

The subgenual organ is a scolopidial sense organ located in the tibia of many insects. In this
study the neuroanatomy of the subgenual organ complex of stick insects is clarified for two …

Comparative studies of the organization of nervous systems and sensory organs can reveal
their evolution and specific adaptations. In the forelegs of some Ensifera (including crickets …

Abstract In Tettigoniidae (Orthoptera: Ensifera), hearing organs are essential in mate
detection. Male tettigoniids usually produce calling songs by tegminal stridulation, whereas …

Anatomy and physiology instructors often face the daunting task of teaching the principles of
neurophysiology as part of a laboratory course with very limited resources. Teaching …

We document the sensitivity to sinusoidal vibrations for chordotonal organs in the stick insect
tibia (Sipyloidea sipylus). In the tibia, the scolopidial subgenual organ (~ 40 scolopidial …
