Male and female

Female fruit flies are larger than male (p. 69), and so are the females of the cochineal, but these have no wings, whereas the males do (p. 66); both male and female goats have beards (p. 52); male drones die of starvation because they cannot feed, and once they have done their job of mating with the queen, the female bees are happy to see them die (p. 15); only female mosquitoes suck blood, and they only do it after they have mated, for the sake of their eggs (p. 10); Asian female elephants have no tusks, though African female elephants and all male elephants do (p. 120); both leeches (p. 105) and earthworms (p. 126) are hermaphrodites but whereas with the leeches one plays the female and one the male, earthworms fertilize each other.
