Etymology

The word retinaculum comes from the Latin retinere meaning 'to hold' and the ending -culum meaning 'small thing', so it literally means a 'small holder' and is related to the English word retain. That's why a retinaculum on a moth is a tiny hook or bristle that holds the back wing to the front wing so the wings stay together in flight.
