6. Bees and Mosquitoes

1

Could you tell someone the way to the grocery store by dancing?

2

Bees dance to show other bees where food is

The dances even tell how far away the food is

3

Bees find food inside flowers

Bees are useful insects because they make honey that people use as food

4

They also make wax which is used to make candles and other products

Honeybees live in a nest called a hive

5

Vocabulary:

honeybees

A kind of bee that makes honey and wax that people use

6

Vocabulary:

hive

A nest made by honeybees

A hive has many rooms with 6 sides

7

The rooms are made of wax and called a comb

8

Vocabulary:

comb

A group of rooms in a beehive

Each hive has a queen which is the largest bee

9

She mates with the male bees, called drones, then lays eggs for the

rest of her life

10

Vocabulary:

drones

A male bee that mates with the queen bee

Most of the bees in a hive are workers that do most of the jobs

11

They build the hive and look for food

When they find flowers, they dance to show others where the food is

12

Then many workers fly to the flowers to feed

They collect nectar and pollen from the flowers

13

Vocabulary:

pollen

A yellow powder that is made in a flower and helps with pollination of the flower

The nectar turns to honey in the stomach of a bee

14

The workers store the honey and pollen in the combs

This is food for young bees, the queen, and the drones

15

16

As they feed, bees carry pollen from one flower to another

Pollen helps flowers make seeds which is another way in which bees

are useful

18

Something bites your arm and a bump starts to grow

It itches and is painful. What insect did that?

19

Probably a mosquito

There are more than 3,000 kinds of mosquitoes

20

Most mosquitoes are about ¼ inch long

They each have 1 pair of wings

21

Most mosquitoes lay their eggs on water

The eggs float and hatch into larvae

22

Vocabulary:

larvae

The wormlike stages of life of some invertebrates

23

When the larvae grow, their skin comes off

Then mosquitoes with wings fly out

24

To find a female, the male uses its antennae to pick up the sound of the

female’s wings

After they mate, the male dies!

25

Only female mosquitoes bite

The female needs to feed on blood to make eggs

26

Some kinds of mosquitoes feed only on frogs or snakes

Others feed on cows, horses, and people
