Monarch Migrations

By:Gabrielle

Introduction

Monarch's have blood flow into their wings which allows them to fly and breathe. Their wings work with the rest of their body to help them migrate and find food. Monarchs show their behaviors with their wings. The Monarch population is decreasing because they either leave too late for migration or they fly too slowly. The Monarch population is decreasing because of the cause and effects their predators and climate.

Life cycle

Monarchs cycle is really short as you can see here. Monarchs lay their eggs on upside down to get there eggs out of the sun and to not show predators where the eggs are and they are in this stage for 3-4 days days as a egg, In this stage caterpillars eat so much because there is nothing else to do and to store up for the pupa stage because the pupa stage is so much work when spinning and wiggling. The larva is in this stage for 10-14 days as a larva. Caterpillars hang upside down because the silk comes out of the other end and it takes this long to transform in a young monarch and if it is past 48 hours due then it is dead and it takes 10-14 days as a pupa. This is the longest time in there life it is where they make new generations of monarchs and because they travel so 2000 miles to mexico and the generation later back to USA and this is how long they live for 2-6 weeks as an adult.

Size,food,reproduction

Monarchs weigh 0.25 to 0.75 and caterpillars weigh more than a monarch probably 2 times the weight monarchs weigh, monarch's also flap their wings 300 to 700 per minute. Monarchs have 4 wings to help the monarch,fly,breathe,and that's where most of the veins are,monarchs produce 4 generations in one summer.

Monarchs hanging upside down

Monarchs are upside down when they are in christis form because they need blood to go to their wings because the silk holds them up at the other end of their head. Adult monarchs hang upside down to either get shade or get out of the rain,keep warm if they are in a group, they also lay there eggs on the other side of the milkweed leaf, which is for shade and not get spotted by predators like wasps.

Patterns

There are only 4 types of monarchs and they are called,the queen,the monarch,the viceroy,the Arizona viceroy. They are all different looking but the only difference with the monarch in the female and male.The queen monarch can be a boy and a girl monarchs.


Wings

Monarchs use their wings for pretty much everything like scent,color,flying and also camouflage to hide away from predators like the big dot on their wings to scare predators to make the monarch look bigger and stronger and for attracting other monarchs and also there veins are in their wings which help them breath in oxygen and communicate.

when,why,where, Traveling

Monarchs follow the sun and use the magnetic field to find there way to mexico and back but to find each other they use their antennas because scientists painted there antennae black to see if there antennas really helped them and they got lost so antennas do help them. In the US you can find them in Washington traveling to mexico a 2000 mile flight and they fly high because up high wind get really fast and they fly as high as 11,000 feet but there normal speed is 4 to 12 miles per hour.

Endangered

Milk weed population has gone down 21% and that's their only resource to live that where they put their eggs and eat and 96.5 % of the population of butterfly have dropped because of that. Ants and spiders eat their eggs and young larva and birds and wasps eat adult butterflies and they also can die on their migration because they can get lost and lost over the sea not eat for a while and lots of other things!


Life cycle

Monarchs have a poison called cardiac glycosides, but some birds and animals are also immune to the milkweed also. to Another reason is that monarchs are a vast food source to other animals and insects in the ecosystem.Having a large amount of monarchs in one area is a sign that it is a healthy ecosystem example is the monarch migration,Monarchs play a big role by being a source of food to others and pollinating flowers for more flowers to grow, without them the food chain would break and a massive decrease would happen in the ecosystem, they control the producers and pollination as well and they provide energy for the secondary consumers.

Forming a pack

Researchers say that monarchs travel to mexico by following other or there scent gland as a road to mexico or back north and they is only one road coming together and i predict that they will eventually come together one by one to form a group to lead each other to mexico or back north, if the monarch is in the pupa stage and it has been black and orange for over 48 hours it is probably dead.



Do they need a Pack?

I predict that They don’t really need travel in a group, sure it would probably safer but they will form a group eventually and they just meet up in states and mexico, Monarchs travel in group to keep warm and keep together to look big and stay warm overnight. Their communication is through scents and color which is how they find there mate but i predict that is how they find there way to mexico and back north.

Population

California monarchs are 5 percent of population and just in 1996 and 2014 monarchs have lost 20 million monarchs, the number one cause of monarchs dying is droughts in the summer. Monarchs are at 57 million now and it use to be at 1 billion monarchs, and the last generation migrates so maybe that's why they went down because the last of the generation migrates and some might be really late in the christitis form and it might be late fall and another reason is because some might not find water food,shelter and predators might find them and they can’t fly away because they are hanging on a branch and in a pack and because they are not fast or warmth like other monarchs and i think the reason why there going down is because monarchs use each other for warmth and the less and less there are the more monarchs freeze to death. Unfortunately the monarch population hasn’t been updated yet to 2015 and i am guessing they are studying them because they just began their migration and are waiting till the end of the year.

Wasps and Monarchs

Wasps lay their eggs on caterpillars to when the wasps hatch they will have something to eat and they will either put the eggs inside or outside of the caterpillar for warmth and food.

Wings fun facts

Monarchs cannot fly in the rain.

Monarchs are in all sorts everywhere but russia and africa.

Monarch wings are thin but strong but they can be worn out ripped and scratched but they can still fly.

Researchers studied that larva and butterflies do hear sound.

Monarchs breathe through the tiny openings on the side of their body called spiracles but they don’t have lungs.

Research say that monarchs do have brains and all insects do.


MIlkweed facts


  • Monarchs eat nectar and water and sometimes they eat liquid from fruit and the larvae only eat milkweed.
  • Adult monarch sip nectar out of the flower like a straw and it is called probiosis.
  • The monarch is a herbivore on the food chain.
  • Monarchs know that a milkweed is a milkweed by using a combination of visual and chemical cues to find it, they use sensory organs on their feet and head to find and know that it is a milkweed.
  • Monarchs eat milk weed because it is poisonous to some creatures and there have the white latex in them which makes them poisonous and stores it in there body for life.
