Looking at the Moth and BeeSlide2
A Quick Review…
What is an insect?An insect has an exoskeleton and has:a
body with three
parts
segmented eyesa mouthfeelers or antennaethree pairs of segmented legs some have a pair of (or two) wings.Slide3
Bee Facts
Bees are related to wasps and ants.Bees live in hives.
Bees are know for producing honey and beeswax.
Bees are needed for pollinating flowers.
Bees feed on nectar and pollen.Slide4
Life Cycle of a BeeSlide5
Life Cycle of a Bee
Some interesting facts:
O
nly one egg is laid per honey comb cell.
The larva does not leave the honey comb to feed. Worker bees bring food to the larva.When the larva is ready to pupate, the honey comb cell is capped off so the pupa is protected.21 days after the egg was laid, an adult bee emerges.Slide6
Moth Facts
When the adult emerges from the cocoon, the wings must become larger. The moth pumps a fluid through them. The moth must wait for the wings to harden before they can fly.
Moth antennae look like a feather or hair filament.
Moths are usually more active at night.
Moth caterpillars can damage agricultural crops.Slide7
Life Cycle of a MothSlide8
Life Cycle of a Moth
Some interesting facts:
Several eggs are laid on the host plant.
The larva must feed itself to grow. It will molt (or shed) several times before spinning a cocoon.
The cocoon protects the larva until the metamorphosis is complete.After the moth emerges, it must pump a fluid through its wings and then wait for it to harden before it can fly.Slide9
Comparing the Life Cycle of the Bee and Moth
Bee
Only one egg is laid per honey comb cell.
The larva does not leave the honey comb to feed.
Worker bees bring food to the larva.When the larva is ready to pupate, the honey comb cell is capped off so the pupa is protected.21 days after the egg was laid, an adult bee emerges.
Moth
Several eggs are laid on the host plant.
The larva must feed itself to grow. It will molt (or shed) several times before spinning a cocoon.
The cocoon protects the larva until the metamorphosis is complete.
After the moth emerges, it must pump a fluid through its wings and then wait for it to harden before it can fly.Slide10
