BBC: Male and female butterflies switch courting roles depending on the season they were born in, say scientists.
Squinting bush brown butterflies use reflective "eye spots" on their wings to attract potential mates.
Males born in the wet season beat their wings to flash their spots but in the dry season females grow brighter spots instead and take the lead.
This behaviour could benefit females, allowing them to control mating when fewer food resources are available.
