Males of Gryllotalpa australis (Erichson) (Gryllotalpidae) and Teleogryllus commodus (Walter) (Gryllidae) produced their calling songs while confined in respirometers.&lt;/p&gt;
&lt;p&gt;2. G. australis males used oxygen during calling at a mean rate of 4.637 ml O2 h&amp;minus;1, equivalent to 27.65 mW of metabolic energy, which was 13 times higher than the resting metabolic rate. T. commodus males used oxygen during calling at a rate of 0.728 ml O2 h&amp;minus;1, equivalent to 4.34 mW, which was four times the resting metabolic rate.&lt;/p&gt;
&lt;p&gt;3. The sound field during calling by males represents a sound power output of 0.27 mW for G. australis and l.51 &amp;times; l0.3 mW for T. commodus.&lt;/p&gt;
&lt;p&gt;4. The efficiency of sound production was 1.05% for males of G. australis and 0.05% for males of T. commodus. Comparison with other insect species suggests that none is more than a few percent efficient in sound production.&lt;/p&gt;
