Question

how insects suck their food​

Answer 1

Ants and caterpillars have strong jaws, like the tweezers, to grip and chew their food. Butterflies and bees have a proboscis, which is a long tube, like a straw, for sucking up nectar. House flies are insects that draw liquids from food into their mouths like a sponge. ... Some insects eat grass and leaves.

Answer 2

Answer:

Many insects are unable to cut and chew solid food, and only eat only liquid food. The strong, sharp mandibles, maxillae and other mouthparts of sucking insects have changed into styluses. These long mouthparts form a tube used to suck up liquid food.

In general, the mouth of a sucking insect works like a pump. Different groups of sucking insects are characterized by the number of styluses, their arrangement and the way they work.
