Cleaning and Counting 7/29/15

So Much Cleaning!

        Last night the heat finally broke and the humidity dropped which was such a relief. Yesterday the milkweed looked awful. If it wasn't shrivelled and yellowing it was wilted beyond anything I've seen. I just didn't touch it and held hope that the heat would pass. And lucky for me it did! So as soon as possible I went out to bring in cuts of the largest plants I could find. And I am not concerned about the fact that I brought in two new ones because I can easily feed them all. As I was trying to fit in my new plants, that are REALLY big, I decided to actually get rid of some plants, which meant a caterpillar transfer. I don't like forcing them on certain plants because they should choose their food, but today it was necessary. So I decided that I would keep one little vase of the least wilted plants in there with the new ones because it had four caterpillars on the stems and an almost ready to hatch egg. The other two vases had to go.
        I do a transfer in a relatively stress-free way for the caterpillars in that I snip the leaves off that they are on and set them on the new plant somewhere safe. I know for sure that I was supposed to have fourteen total including the egg and I was able to track them all down and move them safely. All fourteen are safe and accounted for! It's crazy windy outside so I had to do this in the house, so I apologize for the not-so-great lighting in these pictures.

My two new additions :)

I was shocked this morning by how big my first one has gotten.

The gray gunk behind this guy/gal is freshly shed skin. Hasn't been eaten yet.

        I think that's all for today! It'll be pretty uneventful until my largest decides to go into a hanging J. Write to you soon!

HEY!!!

        Right after this post went up, number fourteen hatched!

Little Helpers 7/27/15

Short Update Today

        Today three of my younger cousins, ages ten, seven, and three, were eager to see my caterpillars. I was asked a million questions, one of which was "Do you need new leaves?" And at first I thought I didn't. Then I realized just how wilted they already were from the heat. One from yesterday was even crispy! It was very frustrating, but my little helpers were willing to go out with me for food. They were excellent at finding good plants, and we soon had plenty of new food for my growing group. Speaking of growing, I accidentally brought in another egg! The count is at twelve. Everyone is healthy.

 
One little guy after shedding. "That's gross!" My helpers said.

A lighter colored friend wondering where all the food is.

        Not much left to say, not much has changed. Hopefully the heat passes soon and my milkweed lasts more than a day. I like observing and having fun, not nervously watching their food supply! Another update tomorrow :)

New Additions 7/26/15

 Updates

        Today it was definitely time to go out and get new milkweed plants for my seven hungry little caterpillars. The temperatures and humidity are soaring here in Minnesota and even my fresh cuts wilted when I brought them in. As long as the leaves aren't crispy I'm never too worried. I took some photos of my caterpillars, but not all of them turned out, so even though I promised you'd see all seven it didn't quite work out. Nonetheless, here they are!
 
As you can see, the leaves are extremely wilted and dying. Darn heat wave!
 
This plant fared better than the others.
 
        Of course as you can see it was definitely time for food! And I couldn't help myself. I added four new residents on purpose.
 
This little guy/gal is really tiny!

 
These two are like twins, they even reside at the top of the same plant.

 
I was even lucky enough to find an egg today!
 
        I don't bring in many eggs, because it's so easy to get your hopes up. But the reality is any kind of trauma can kill the egg. Other caterpillars hitting it or walking over it, hitting the stem or other leaves too hard, and even other bugs interfering can cause them to die. The best and as far as I know only way to know for sure if an egg is dead is if the entire thing turns dark blackish-purple. Not to be confused with what it looks like just hours before it hatches however. Just before the tiny caterpillar breaks free, the very top of the egg will turn black. That is of course the caterpillar's face.
        Eggs are difficult to find because there is only one on each leaf and they are generally on the underside of the leaf. Not to mention they are tiny and easy to miss! From what I have observed, eggs hatch within five days. Then the little gray caterpillars earn their bright stripes within a day or two. They remain little eating machines for two weeks (fourteen days) before finding a suitable place to make a chrysalis. Before they shed their skins to reveal the beautiful pupa underneath, they prepare for nearly forty eight hours. First they make a little silk button from silk threads produced from their mouth. Then they hang upside down in a "hanging J" getting ready to change. When the time comes, their skin splits revealing green underneath. Then they are in the pupa phase for ten two twelve days. The chrysalis then darkens with the patterns of the butterfly just two days before the butterfly flies away. It's truly amazing to watch.
        I have been asked by many people if I want to make this a career someday, and I honestly don't know. Entomology would be an amazing career to pursue, in fact anything in the biology field would be. Knowing that this is my passion you'd think it would be an easy decision to say "Yes! That is what I want to do in life!" But in fact like every other teen I am still figuring out what I want to go for. Teaching would be a rewarding career as well. I could use my butterflies as a learning tool in the spring and teach my students about milkweed and how to coexist with nature. And I love other kinds of biology as well! No matter what I choose to do I am hoping to have an adequate supply of milkweed at my home. I could never give it up.
        There isn't much else to say today. I will continue to post updates about, as a friend so eloquently put it, my flying beauties. Write to you soon :)

Caterpillar Updates + What is Milkweed? 7/25/15

Little Update On Caterpillars

        Today was an uneventful day, but I was able to snap some pictures of the caterpillars that weren't hiding. 

This is my largest caterpillar at the moment. He/she isn't quite an inch long.

Busy munching away!

When Monarchs are ready to shed their skin, they lose their appetite.

And my littlest! When they are this small, they only eat the surface of the leaves,
and leave behind a lot of frass that is too small to roll off the plant.

        All seven are acting and eating normally. Watching for infection is a must with Monarchs. Signs of it may include difficulty shedding skin, watery and discolored frass, or simple unresponsiveness. Other times they seem perfectly healthy until the pupa stage. However, when it's time for them to shed skin they DO stop eating and don't seem very responsive. It's normal, and will pass within the day. The only gross part is watching them turn around and eat their skin when they're done!

So, What is "Milkweed"?

        Milkweed is the plant, the ONLY plant, that Monarchs eat. It is a weed, which is why a lot of people feel like they absolutely have to get rid of them. They are often sprayed with pesticides to get rid of the caterpillars and beetles that like them. But milkweed being killed is the leading factor in Monarch population decline. If you see it, leave it alone. If you want it out of your garden, check it for Monarchs, then if the coast is clear, dig it up. It grows back from the root, so there's no sense in chopping it off. I do highly encourage you to leave it be, because the butterflies need it in order to survive.
        But what does it look like? How do you know if you're looking at milkweed? Well, I went out today and took some pictures to show you.

This is milkweed in a field. It is most commonly found in prairie grasses.

But don't be fooled! It can grow almost anywhere. This was found along the edge
of a forest, just inside the tree line.

These were even found next to my garage. The leaves can be rounded like the 
previous photos, or come to a point like these.

When it blooms, it attracts all sorts of pollinators such as this Swallow Tail.
(See the monarch photo-bomb in the back?)

It can appear in huge quantities!

And if you are still unsure, tear a leaf through the stem. It should "bleed milk".

        So there you have it, if you are looking for Monarchs to raise yourself or if you simply want to preserve their food, that's what to look for. Simply letting these plants grow could save a butterfly.
        I will write to you tomorrow with pictures of all of my caterpillars. My plants are starting to look wilted and speckled, so I will definitely be out getting food. And maybe even more caterpillars....

Welcome to My Blog! 7/24/15

In the Beginning

        Hello! My name is Sam, and I am a fifteen year old girl from Minnesota. I have been raising Monarchs from caterpillar to butterfly since I was eight years old. My interest began at around the age of five or six with Painted Lady butterflies, and it blossomed from there.
        As a child, I was always interested in nature, animals, and bugs. My family never hunted and I learned to appreciate the way life moves and works by simple observation. From the time I could walk I was chasing butterflies. Moths sparked interest too, but nothing captivated me quite like the bright colors of a butterfly. My parents fueled this interest with butterfly nets and bug keepers. I would catch, look, and release everything from grasshoppers to worms. We were subscribed to a little kid nature magazine where you could order these things, and one day something caught my mother's eye. It was a butterfly container that you could order caterpillars to go along with! Naturally we sent in our order, and little six year old Sam was eager to see metamorphosis in my very own bedroom.
        When the caterpillars came in the mail, I was a little disappointed. There were probably seven Painted Ladies in a clear plastic jar with muck in the bottom. It said not to ever open it while they were larvae. They munched the unnatural looking brown substance and grew only a little. Not long after they arrived, they decided to enter pupae. We were to pin the lid of the jar to the top of the mesh enclosure and wait. They were all released into a much more natural environment once the little brown butterflies emerged. I definitely enjoyed the experience, but it seemed so unnatural to have them in a jar so close together. I never ordered them again, but I kept the enclosure. 
        Two years later, when I was in third grade, the class began a science project that brought back my butterfly love. The teacher announced that we would be raising Monarch butterflies. I expected something similar to the jar that I had, but much to my surprise, they were brought in on whole plants by the teacher in the classroom next to us. We got to hold the plants for an up close look, watch eggs hatch, and hold the butterflies outside before release. I was hooked. I had to do it! That summer I found my little mesh cage and set to work looking for caterpillars. I would bring in individual leaves to scatter on the bottom of the cage. I used this method for two years, an although the mortality rate was quite high because of it, I had fun. I would still manage to release four or five butterflies each summer. At the age of ten I started cutting down whole plants to put in vases for them. It worked much better, and I started having around ten butterflies each year.

Currently

        After I started using milkweed cuts instead of leaves, I realized how inconvenient my enclosure was. It had thick white mesh that was difficult to see through. Not to mention it had one tiny door at the base of it, and when you're releasing butterflies, they want to go up! It was rather short, so tall plants did not usually fit. In the spring of 2012, I told my dad about my problems with the cage, and he started making plans with me. He is very talented in design and building, and this is what he built:




It is 2ft in height, and the roof and base are 1ftx1ft

        The sides of the cage are window screens cut to fit. The back wall and front swinging door are plexiglass. The door does latch, and the top has a handle with leaves on it. My dad did an amazing job!
        It works extraordinarily well to this day, and my success has skyrocketed. In 2012 I had fifteen successful, in 2013 there were 23, but in 2014 just two. The caterpillars would seem so healthy, and as they made a chrysalis they would disintegrate. It was painful to see six out of eight die at the top of my enclosure, so I didn't bring any more in. I asked a local "Bug Guy" in the fall why it happened, and he seemed fairly certain it was a bacterial infection. He suggested washing my enclosure in bleach. I was hesitant, because bleach could harm them. But after reading about other people's caterpillars on the internet I decided it was best. They suggested using a 20% bleach solution and thoroughly rinsing afterwards. I did just that this spring, and have had thirteen releases already!  
        Over the years I have learned patterns in egg laying and migration, so I can typically have two rounds of caterpillars in one summer. Round one starts in late May and early June, and round two starts mid to end of July. As I mentioned, round one had thirteen successful Monarchs. I cleaned the enclosure with a bleach solution again, and just began round two. I have seven tiny caterpillars, and I will update you on their progress almost daily! I will also include photos as often as possible. I hope you find interest in my blog, and I will write to you tomorrow. :)
