The anatomical development of the tympanal organ, the tracheal system and the tympana of Teleogryllus commodus is described. The tympanal organ is undifferentiated until instar 3 when the first scolopales appear. The organ develops in a proximo-distal direction but the more distal groups begin to form before the proximal groups are complete. All groups of scolopidia are represented in instar 7 but numbers of scolopidia continue to increase until the adult stage. Scolopales and scolopale cells are first formed at less than adult size and increase in size during subsequent instars. The subgenual organ is present in instar 1 and is complete in instar 4. The posterior and anterior tympanal trachease develop respectively from the tracheal trunk and tracheal branch, which are present from instar 2. These remain as simple, unconnected tubes until instar 7 and begin to show the adult form during instars 8 and 9, finally enlarging in conjunction with the tympana at the last two moults. The tympana first appear as hairless areas of cuticle in the larval stages: the posterior tympanum in instar 8 and anterior tympanum in instar 10, but the translucent appearance of the adult tympana is not present before the final moult.

Adult structure JF - Zeitschrift für Zellforschung und mikroskopische Anatomie Y1 - 1974 A1 - Young, David A1 - Eldon E. Ball AB -

The microanatomy of the adult auditory system of the cricket, Teleogryllus commodus, is described with special attention to the number and arrangement of the groups of scolopidia forming the tympanal organ.

In the proximal part of the prothoracic tibia, there is a large posterior tympanum and a smaller anterior tympanum, which are associated internally with two expanded chambers of the tracheal system. The tympanal organ, which is identical in both sexes, is situated on the dorsal surface of the anterior tympanal trachea. It contains about 70 scolopidia, divided into two main groups: the proximal group, whose attachment cells insert on large accessory cells dorsally within the tympanal organ, and the distal group, whose attachment cells insert on modified dorsal hypodermal cells. These groups can be further divided into five main types, each containing a relatively constant number of scolopidia: 1. proximal group A; 2. proximal main group with proximal neurons; 3. proximal main group with distal neurons; 4. proximal part of distal group; 5. distal part of distal group. These types differ consistently in the following features: location of sensory neuron, orientation of dendrite and scolopale cell, structure of scolopale cell, shape and orientation of attachment cell and its connection to the secondary attachment cell.

The stridulatory surfaces consist of opposing series of microlamellae, only seen clearly with the surface scanning electron microscope. Sound emission covers a wide band of frequencies from audible to about 80 kHz. It is suggested that stridulation may act as an acoustic warning to certain vertebrate predators.
