How Does a Fly Eat?

How Does a Fly Eat?

A fly cannot bite or chew because it cannot open its jaws. Reaching down the front of a fly’s head is a tube like part called a proboscis.

The fly uses its proboscis as a straw to sip liquids. When a housefly lands on a piece of sugar or other solid food, it turns some of the food into liquid by spreading saliva on it. It then sops up the liquefied food with spongy pads at the tip of the proboscis.

“Biting” flies have needle-like mouth parts hidden in the proboscis. These flies stab their sharp points into a victim’s skin and then suck up the blood.
