Variation among male G. assimilis in their long distance acoustic mate attraction signals, enzyme activities, thoracic and abdominal percentages of carbohydrate, glycogen, and lipid, and morphology.

Difference = max/min values. Abbreviations: TSC (time spent signalling), Dur (duration), and Freq (Frequency), PK (pyruvate kinase), GP (glycogen phosphoylase), CS (citrate synthase), HOAD (β-hydroxyacyl-CoA dehydrogenase), TRE (trahalase), HK (hexokinase), Thor (thoracic), Abdo (abdominal), Pro (pronotum), Carb (carbohydrates), and Gly (glycogen). Enzyme activities are in U/g of muscle, where 1 U = 1 µmol substrate/min. Units: TSC (min), Pulse Dur (msec), Inter-pulse Dur (msec), Chirp Dur (msec), and Inter-chirp Dur (msec), Carrier Freq (Hz), Amplitude (dB).
