- •
We investigated the correlation of male courtship and ornamentation with testis size and sperm length in Chrysomya varipes.
- •
Males that courted females more intensively had bigger testes.
- •
Males with more ornamentation on their forelegs had sperm with longer tails.
- •
Males that invest more in courtship and ornaments are assumed to be more fertile.
- •
These findings lend support to the phenotype-linked fertility hypothesis.
