- •
We investigated why male crickets show same-sex sexual behaviour (SSSB).
- •
More aggressive males were more likely to court other males.
- •
Males on high-carb diets that signalled often also courted other males more often.
- •
Males were more likely to be courted if they were less aggressive.
- •
