Texas field cricket
Gryllus texensis

Ovipositor length as a function of pronotal width in G. texensis (open symbols) and its close relative, G. rubens (solid symbols). Identification was based on the songs of brothers (triangles) or the locality (circles). (G. rubens and G. texensis occur without the other species at the eastern and western extremes of their ranges respectively.)
