Monarch Caterpillars Head-Butt Each Other to Fight For Scarce Food

    Article

            With a scarcity of food for the monarch caterpillars, they have become aggressive. The article talks about how Monarch caterpillers behave and act with the decreasing food availability. Alex Keene started observing and researching the activities the Monarch's have shown. The insect only eats milkweed, and survive on the plant until the grow/bulk up. "Making things more difficult, the caterpillars need a huge amount of food to transform into a butterfly." The monarch, from egg to chrysilis multiply in weight 3,000 times. Researchers have pointed out that some are more aggressive then others. The next steps into this research of the behavior is to see if the cateripillers will grow into aggressive butterflies. 

    I found this article to be very fascinating. The thought that Monarch caterpillers are now becoming aggressive towards each other because they are losing food sources makes sense, since they cannot travel far. The caterpillars basically live off the milkweed plant they were born on until they move into the chrysalis. I found it sad that they Monarch caterpillers now have to fight for their food and I hope that they don't grow into aggressive butterflies.

    So monarch caterpillars get aggressive without food. I think I might be a monarch caterpillar. Maybe monarch caterpillars will start to find other food sources or develop harder heads and more powerful fighting skills or just get faster.

    I think it is very interesting that these caterpillars are so aggressive to each other. I wonder how the butterflies would act if this happened to them. Do you think the caterpillars will loose all their food source at one point?

Current event

I am just doing a trial current event-  Are you supposed to put the link to your article in the summary?  Do you know how to do that?  My current event is an article from the magazine The Week.  It is titled   It's not just the germs — it's also the genes  The article discusses how a person's genes play a part in how viruses react within that body.  It talks about how some people may get a virus more seriously than another & how scientists can look at that information and develop therapies from.  Just so you know The Week pulls articles from other sources-  I did backtrack to check the source they got the original article from & it checks out.

Over 87,000 papers published on coronavirus since start of pandemic

 Over 87,000 papers have been published about this global pandemic. When most people think of the pandemic going around right now, they think about how awful it all is. How many people have died, how many people have lost a family member, or how many people they have lost relationships with friends or family. But, do people ever think about how this event will go down in history, and how it will affect science studies in the future? We never know what type of science we will come across in the future, but we can say that science evolves every day, and things are constantly changing. This is why so many people are interested in this pandemic. The more we know about this pandemic, the more we can do to try and change is. So, what will science bring in the future? And how will it impact future in sciences? We won't know the answer to either of those questions for a long time, but we can certainly say that it will evolve so much, and make things a lot more interesting.    htt...
