nectar. The males have weak mouthparts; only the females bite animals,
including humans, to obtain enough protein from the blood to produce
eggs. For this they use a stout stabbing organ and two pairs of sharp
cutting blades to bite, and a spongelike part to lap up the blood that
flows from the wound. They can transfer blood-borne diseases from one
animal to another. They can also reduce growth rates in cattle and lower
the milk output of cows if suitable shelters are not provided; some
animals have lost up to 300 millilitres of blood in a single day to the
insects. Horseflies prefer to fly in sunlight, avoiding dark and shady
areas, and are inactive at night. They are found all over the world
except for some islands and the polar regions. The larvae are predaceous
and grow in semiaquatic habitats. Horse-flies have appeared in
literature since Aeschylus in Ancient Greece wrote about them driving
people to madness. Gadflies (horse-flies and botflies) are mentioned in
Shakespeare's plays King Lear and Antony and Cleopatra.
