Transcript of Monarch Butterflies! >-<
Species: Lepidoptera Nymphalidae Danaus
D. Plexippus Monarch Butterfly! Physical Characteristics: Orange and black patterns! Female Monarch butterflies have darker, thicker veins on wings than male Monarch butterflies Male Monarch butterflies have a black spot on each back wing, females do not Male Female Habitat In the spring, summer and early fall, they can be found wherever there are milkweeds. Monarch butterflies can be found in a wide range of habitats such as fields, meadows, parks, gardens, trees, and roadsides. This is how milkweed plants look like! :D Diet "Food as Fuel" The larvae (caterpillars) of Monarch butterflies eat ONLY milkweed, this is why the Monarch butterfly is nicknamed the ‘milkweed butterfly’. Adult Monarch butterflies only feed on nectar, the sugar-sweet juice inside every flower. They use a tube called proboscis, which is a hollow drinking straw, to slurp the nectar. You should know something else about the Monarch butterflies ... Symmetry Now, you might think an adult Monarch feed on milkweed plants too! NOOOOOO! Larvae
eating milkweed A close-up at
proboscis! Reproduction Interesting Facts Did you know? Monarch butterflies are poisonous! :O Did you know?
Monarch butterflies are one of the largest butterflies on Earth! Monarch butterflies are the long-distance champion among the other butterflies Monarch butterfly drinking nectar Like all insects,
Monarch butterflies lay eggs to give birth. Each mating can have a few hundred eggs! Movement Monarch butterflies travel in groups of 1-5. But, when they are on their migration, Monarchs travel in millions. For Monarch butterflies, groups are known as a mass They fly on two pairs of wings over cities, forests, mountains and deserts. Migration At the end of September and early October, Monarch butterflies leave on a long journey called migration and travel to warmer lands. Monarchs fly and ride in the wind south in the autumn, traveling up to 3 000 miles (4 800 km) to Mexico and California. Fall Migration
(September - November) Spring Migration
(March - June) Unlike most insects in temperate climates, Monarchs cannot survive in a cold winter. So instead, they spend the winter in roosting spots. Map of Distribution Monarch butterflies are found all over the WORLD! by
Yuan Yuan This white Monarch was found in Hawaii! Endangered! How did Monarch butterflies become endangered? The Monarch butterflies are endangered because of habitat loss, human disturbance, terrible weathers and other predators. Few millions, they don't hold long enough for proper count. NOOOO! What did humans do to impact them? People are using herbicide to kill milkweed, which means fewer places to lay new eggs and the chemicals in the herbicide are harming all Monarch butterflies! The biggest threat for the Monarch butterflies is people cutting down trees in forests to make furniture, medicines ... etc. If people are cutting trees down, the Monarchs will have no place to go in winter, which means they WILL die. What consequences will people face if Monarchs become extinct? In the world, there are so many Monarch butterflies ; if they become extinct, it would have a huge impact on the ecosystem How can we help save the Monarch butterflies? Plant a butterfly garden Stop using herbicide Predators When Monarchs are hibernating, different forest animals eat them. That causes females unable to fly back and lay new eggs. Examples of the forest animals: Gray catbird Black-eared
mouse Why should we save
the Monarchs? Danger in forests! This white Monarch is SUPER RARE! The binomial nomenclature of the Monarch butterfly is D. Plexippus! Participate in fundraisers, like the Earth Rangers! How many are left in the world? People are also helping the Monarchs out of its chrysalis, and guess what? They won't be strong enough to fly ; most of them will die. We want to save them because they pollinate. Inside each flower, there's pollen. The Monarchs go to different flowers to drink nectar. The pollen stick to their leg, and when they fly to another flower, Monarchs will drop the pollen. That's one of the ways new plants are reproduced, and some animals needs certain flowers to survive! Butterflies are classified as insects because they have ... 3 main body parts
1 pair of antennae
2 compound eyes
2 pairs of wings (Some insects are different from a butterfly) ANTENNAE HEAD THORAX ABDOMEN WINGS EYES Thank you for

Book: National Geographic Did you know?
The farthest recorded Monarch travel is 265 miles in one day. Monarchs can flap their wings up to 2 000 times a minute! Monarch butterflies weighs less than a paper clip. Each year, the Monarch butterflies’ migration takes several generations. Three or four generations complete the journey north. But only one generation makes the return trip south.
How does it work?
The first three or four generations live two to six weeks as adult butterflies. During the spring the first generation hatches in the south. They fly north as far as they can. Then, they lay eggs and later they die.
The second generation continues the journey, lays eggs, and dies. The third and sometimes fourth generation hatch through the spring and summer. They finish the trip north.
At the end of the summer, a special super generation hatches. These butterflies live six to nine months, much longer than the generations before it.
In fall, the super generation flies south without laying new eggs. That’s why they are called the super generation. Journey North! How do they find their way? The Monarch butterflies know where to go by instinct. Female Monarchs lead their way. Sunlight signals guide them to Mexico and California. Since we live in Canada, I'll focus more on the American, Canadian and Mexican Monarch butterflies. Spider Weather Cold Temperatures Monarchs need warm temperatures to fly. When temperatures get too low, Monarchs will die. How deadly? A rainstorm with low temperature killed as many as 250 million Monarchs in Mexico, 2002. CANADA ROCKY MOUNTAINS U.S.A MEXICO CANADA U.S.A ROCKY MOUNTAINS MEXICO SOUTH NORTH Biodiversity We also want to save the Monarchs because if they die, so will the animals that eat them and soon, many species will be extinct. ALL LIFE IN THE WORLD IS CONNECTED! Food as Fuel: Adult Monarchs do not need to grow anymore. So instead, they use food as energy to fly. 326 eggs!
Which means 326 new lives! There's this butterfly called Viceroy butterfly. It looks like a Monarch butterfly, but it's not a Monarch. -.- Monarch butterfly Viceroy butterfly MONARCH
COPIER! Don't be fooled! But sadly, white Monarch are extinct. :( Random Topic! But, it's pretty cool. TWINS!
