The monarch butterfly is an animal you will probably have seen around in your
life. It's not the kind of animal you will know the name of, much less the
extinction status, but the monarch butterfly is rated "endangered" on the WWF
website. It's affected by climate change and humans and its numbers have
declined greatly.
Fast Facts
The Monarch Butterfly is a rather small animal, however pretty large for one
of its species. Their wingspan ranges from about 90 to 100 mm, the male
butterflies being slightly larger than the female. They are orange with a
black patterning and white dots on the sides of their wings, the vibrant
colours warn predators of their bad taste. Monarch butterflies are known for
their migration habits. They are mainly found in northern America, but travel
to the south (Mexico or California mainly) to hibernate. These tiny
butterflies travel almost 3 thousand kilometres and can be found all over the
planet by now. They have adapted with shape and size to live all over the
planet! Monarch butterflies usually only live a few weeks, except for those
who travel south. Those live for up to 9 months! This results in roughly 4
generations of monarch butterflies a year.
Monarch butterflies lay their eggs on milkweed plants. The caterpillars can be recognized by their vertical stripes of black, white and yellow-green.

Endangerment
Of course, there are more than just a couple of factors to the decline of
monarch butterflies, but climate change, deforestation and fewer milkweed
plants to lay eggs on are the main problems. We all are aware that climate
change alters the general weather and climate of our planet and that that in
return affects animals and plants in many ways. The monarch butterfly is very
sensitive to that, as different temperatures in its breeding grounds would
affect its migration route colder winters would kill the butterflies.
Additionally, the monarch butterfly (like so many animals) is affected by
deforestation. It hibernates in the mountain forests in Mexico for example
where humans are also active in tourism and agriculture. Pesticides are used
in agriculture but also decrease the number of milkweed plants available for
the butterflies to lay eggs on, which makes reproducing difficult.
