The evolution of acoustic behaviour and that of the morphological traits
mediating its production are often coupled. Lack of variation in the
underlying morphology of signalling traits has the potential to constrain
signal evolution. This relationship is particularly likely in field
crickets, where males produce acoustic advertisement signals to attract
females by stridulating with specialized structures on their forewings. In
this study, we characterize the size and geometric shape of the forewings
of males from six allopatric populations of the black field cricket
(Teleogryllus commodus) known to have divergent advertisement calls. We
sample from each of these populations using both wild-caught and
common-garden-reared cohorts, allowing us to test for multivariate
relationships between wing morphology and call structure. We show that the
allometry of shape has diverged across populations. However, there was a
surprisingly small amount of covariation between wing shape and call
structure within populations. Given the importance of male size for sexual
selection in crickets, the divergence we observe among populations has the
potential to influence the evolution of advertisement calls in this
species
