Transcript Ladybugs - Welcome to Reyli Family Website

INSECTS ARE EVERYWHERE!
Third Grade Objectives
Compare life cycles of different animals.
Classify animals according to characteristics.
Summarize text, sequence information.
Use graphic organizers.
Go outside on a warm summer day. Look around.
What insects do you see? You might see bees and
butterflies flying from flower to flower. You might see
ants scurrying across the sidewalk. You might see
ladybugs crawling on leaves.

LADYBUGS . . .

Where can you find a LADYBUG?
Interesting LADYBUG facts?
LADYBUGS – Part I
These tiny predators are usually very welcome in gardens because ladybug larvae and adults eat
aphids, mealy bugs, and mites (which are garden pests).
Ladybug larvae can eat about 25 aphids a day; adult ladybugs can eat over 50 aphids a day.
Ladybugs live in a variety of habitats, including forests, fields, grasslands, gardens, and even in
people's houses.
As a defense, ladybug adults will fall to the ground and "play dead." They also can secrete
an amber bad tasting fluid from the joints in their legs to protect themselves.
Beetles make up the largest insect family and come in all shapes and sizes. Ladybugs are small beetles.
There are about 250,000 different kinds of beetles! The largest beetles are called Hercules. They can grow
to be more than six inches long!
All ladybugs have a special wing covering. The covering is actually a pair of wings. These “covering”
wings protect the flying wings underneath. They act like a hard outer shell.

How does a LADYBUG grow?
How many stages are in the life cycle of a LADYBUG?
How long does it take for the LADYBUG to go through its life cycle?
During the LADYBUGS life cycle did you begin to notice that your
insect started looking like its parent?
Which stage did you notice this?
LADYBUGS – Part II
Female LADYBUGS lay tiny eggs, usually laid in a small mass (fertilization is internal).
The larvae that hatches from the egg is small and long and has 6 legs. As it rapidly grows, the larva molts
(sheds its skin) several times. After reaching full size, the larvae attaches itself to a plant leaf or stem (by its
"tail").
The larval skin then splits down the back, exposing the pupa. The pupa is about the size of the adult but is
all wrapped up, protecting the LADYBUG while the it undergoes metamorphosis into its adult stage. This
last stage in the metamorphosis takes a few days.
The LADYBUG, like all beetles, undergoes a complete metamorphosis during its life.
The life stages of the ladybug are:
egg --> larva --> pupa --> adult
The length of the life cycle varies depending upon temperature, humidity, and food supply. Usually the life
cycle from egg to adult requires about three to four weeks, or up to six weeks during cooler spring months.
In the spring, over-wintering adults find food, then lay from fifty to three hundred eggs in her lifetime (tiny,
light -yellow eggs are deposited in clusters of 10 to 50 each) in aphid colonies. Eggs hatch in three to five
days, and larvae feed on aphids or other insects for two to three weeks, then pupate. Adults emerge in
seven to ten days.
There may be five to six generations per year. In the autumn, adults hibernate, sometimes in large numbers,
in plant refuse and crevices.
When does the LADYBUG begin to started looking like the parent?

LADYBUGS – Part III
Bees, butterflies, ants, wasps and LADYBUGS all look different. But they are all
insects. And, all insects are alike in some ways.
All insects, including LADYBUGS, each have six legs. All insects each have
three body parts. They have a head, a thorax, and an abdomen.
All insects have an exoskeleton. This is a hard covering on the outside of
their bodies. Most insects have antennas. Most insects also have wings and
hatch from eggs.
