antennea, and mouthparts. Pictured below are the head of a house fly, a
butterfly, a mosquito, and a beetle. |

flattened, rounded structure used for sapping and sponging
liquified food. Many flies have this type of mouth. |

and moths have siphoning /coiled type mouthparts. This type of
mouth is a highly coiled tube which the insect uses to suck nectar from
deap within a flower. |

Mosquitoes
have piercing-sucking mouthparts. This type of mouth is modified
for piercing the food and then sucking the liquid portion. Other insect
orders such as Hemiptera (bugs) and Homoptera (cicada, leaf hoppers,
lace wings) have this type of mouth often on the ventrical surface. |
