- •
Recently mated males of the moth Achroia grisella show precopulatory mate guarding.
- •
We exposed recently mated males to the playback of a male courtship song.
- •
Exposure to competition induced extended guarding but no increase in sperm transfer.
- •
Mate guarding intensity and sperm expenditure were independent of female mass.
- •
A second experiment demonstrated a male, but not female, response to male competition.
