Life Cycle of a Lady Bug• Average life is 1-2
years.• The life cycle
starts with an egg, hatches into larva, develops into a pupa, and then finally becomes an adult. At the adult stage, the lady bugs reproduce to create more eggs.
Flies
• A flies locomotion or way of getting food is by flight.
• They use mandibles to chew food, spit it out, chew it again, and then eat it.
Circulation
• Insects have an open circulatory system. The blood found in their body can come in contact with other organs inside of their body.
• Responsible for movement of nutrients, salts, hormones, and metabolic wastes.
Gas Exchange in Insects
• Insects have tiny holes called spiracles
• Found on side of insect• Tubes are connected to
cells, containing fluid• The fluid is liquidized gas• Cells are enlarged, and gas
is released through the spiracle
How Insects Digest Food
• Alimentary canal; enclosed tube• Saliva is mixed with the food• Foregut (where food is stored until
further processing)• Midgut; nutrients is absorbed• Hindgut; water is absorbed
How Insects Excrete Waste
• Almost similar to humans
• Too small to see
FACT: Every time a fly lands it excretes waste
Fun facts
• There is believed to be between 6 and 10 million different insect species
• Insects have three pairs of legs• Only male crickets chirp• Insects are cold blooded
