Why does a mosquito bite itch?

The itchy welt you welt you get from a mosquito bite is caused from the saliva the mosquito injects into the skin.  The saliva keeps the blood from clotting so that the mosquito can easily sip your blood.

Most of us are allergic to the mosquito saliva, and the itchy welth that forms on the skin is very irritating.

Only the female mosquito “bites.”  The male mosquito feeds only on plants juices.  The female mosquito does not really bite.

To the eye, her needlelike beak looks like a think tube.  Actually, it holds daggers with saw-like tips.

As soon as she settles on your skin, she starts sawing.  Into the tiny hole she injects the saliva that helps her to sip the blood.

If you swat her before she can suck back the irritating saliva, your itching will be worse.

Next to its bite, the hum of a mosquito is probably most annoying – especially when we are trying to sleep.  The hum of a mosquito is the sound of its wings beating rapidly as it flies.

How do butterflies eat?

Butterflies are gaily colored insects we often see on summer days.  They flutter from flower to flower drinking the sweet liquid called nectar.

Butterflies have no chewing mouth parts.  They cannot bite or chew.

Instead of the usual insect mouth, the butterfly has a long, slender tube which is used to suck up nectar and other liquids the way you sip through a soda straw.

When the butterfly is not eating, the long tube curls up like a watch spring under the insect’s head.

A butterfly’s taste buds are on the soles of its feet.  When it alights on a flower, the sweet taste causes the insect to uncoil its sucking tube.

When butterflies go from one flower to another for the sweet nectar, they also pick up some pollen on the hairs of their legs and bodies.

A little of this pollen brushes off as they visit each new flower.  It helps the flowers’ seeds and fruit to grow. – Dick Rogers
