Food Web - Monarch Butterfly
Transcript of Food Web - Monarch Butterfly
Its Place... The Monarch Butterfly is a milkweed butterfly and
is probably the most known butterfly in all of
North America. The monarch butterfly is in the 'Nymphalidae Family' and in the 'Danaini Tribe.'
In a food web, the Monarch Butterfly is considered as a herbivore. Monarch Butterflies and Their Strengths In Defense... The Monarch Butterfly may have poisonous toxin in
their bodies from when they consumed the milkweed plant which contains a special chemical that is poisonous to many animals but not the monarchs. They eat this plant as a caterpillar, and the poison is contained in their cuticle(skin) which stays there and protects them. But even so, some animals can still eat monarch butterflies. The Monarchs' Predators... The monarch butterfly may contain poison in their skin, but few animals can still find a way of its own to eat the butterfly; in which leaves some clues in which to having their identities found out.
Three animals whom eat these butterflies are:
-The Black-Eared Mouse (Peromyscus melanotis)
-Black-Headed Grosbeak If Gone... If the monarch butterflies suddenly disappeared, the black-eared mouse(Peromyscus melanotis), black-backed orioles and black-headed grosbeak, in other words the monarchs' predators; would lose one of their main food sources. Milkweed would not be eaten, unless us humans would start eating it or other animals that can eat the cardiac glycosides that is contained in milkweed. Otherwise, it would be left for those animals who will die from the poison. The Predators... Thankfully, the predators have other sources of food rather then one, for example:
the black-headed oriole eats berries and insects, spiders and fruit, pine and other seeds. This way, even though if the monarch butterfly somehow becomes extinct, this bird still has other sources of food.
But either way, we should not put that as an excuse to not help out the monarch butterfly and try to do our best to keep it in a safe environment for them. How To Help... A way to help make sure that the monarch butterflies don't become extinct due to lack of food, we should make sure not to destroy, or kill the milkweed plants for the monarch butterflies and caterpillars to eat. We can plant new ones in the backyard or a community garden, and watch as they grow. Encourage others to help with saving the monarchs. Population decreasing... Every year when the monarchs move to Mexico to hibernate in the winter, millions of then are eaten. Scientists estimate that in a typical year, more then 15% of the entire overwintering population is killed by predators. Even though they have protection from poison, the butterflies' predators have their own way of consuming the monarchs. That is why poison is not the only protection from predators. Another way of protection is to form colonies to defend themselves, this lowers the probability of any individual butterfly getting killed. But even so, slowly, by time, the butterflies' population is decreasing. Its Not The End... You now understand why it is important to protect and do our best to protect the monarch butterfly species from extinction.
Its not the end of the life span of the monarch butterflies as their generation continues on and on, so you should take this opportunity while you have it to help this species in any way you can. By: Mandy Chen Room211
