"For teachers... who see the child before the student, who remind us that we all have special gifts to offer the world, who foster the importance of standing out rather than fitting in." Lynda Mullaly Hunt

Differences Between a Moth and a Butterfly

Butterflies and moths are both in the same order Lepidoptera, which are scale-winged insects.  Lepidoptera have wings with colour patterns created by tiny, overlapping scales, which are modified hairs.

Even though butterflies and moths can look alike, they do have some differences that you can look for:

Butterflies:
  • Rest with their wings closed
  • Long, thin antenna
  • Generally active during the day
  • Butterflies usually create a shiny chrysalis
Moths:
  • Rest with their wings open
  • Shorter, feathery antenna
  • Generally active at night
  • Moths create a silky cocoon

Social Media Awareness with Jesse Miller

Today we had a great speaker named Jesse Miller come in and speak to us about social media awareness and what an eye opener this was.  I had no idea to what extent our digital footprint goes out into the world without even being aware of it.  He spoke to use about digital identity,   digital rights, and digital literacy which are all very important topics especially since all of us are entering into the teaching career.  We must be aware of our presence on the internet and how we must be accountable in our social channels, especially in connection to our work and our professionalism.

One of the topics Jesse spoke to us about is privacy and how teachers must be aware of the use of personal phones in the classroom for documenting and representing students and their work.  A point that I took home today is the importance of using a camera that is not part of the school network or hooked up to the internet in any way for uploading images to applications such as FreshGrade.   We must be accountable and realize that the parents may not have given us permission as a teacher to upload that students photograph to Icloud, even though your intention was only to put it on to  FreshGrade.  We must also asks ourselves if the students name is in the photograph of the artwork and how that can also be a breach of privacy, especially if the school address is disclosed with the photograph.

Technology for kids provides opportunities for success and conflict.  This is an on going conversation, but at the end of the day we must realize that technology is a part of our future.  Jesse asks us to question our thoughts of addiction around screen time, and whether or not it is an addiction or a comfort.  Technologies provides a platform for opportunities that would not exist without it.  Schools can connect with low income families via social networks available online, where as without it those connections would be lost.

We must be aware that anything we do online is accessible, and can be tracked.  If we delete a photo on Facebook, it isn’t really gone.  If we look up someone on Facebook or Instragram it can be tracked.  Our digital footprint follows us where ever we go and as a teacher we must be willing to look at ourselves and be accountable for what our presence is online because parents and employers, or even creepers will look us up and try to find out what ever they can about us for good or for worse.

The Life Cycle of the Polyphemus Moth

Polyphemus moths lay flat, light-brown eggs on a variety of leaves in trees such as birch, willow, oak, maple, and beech.

https://en.m.wikipedia.org/wiki/Antheraea_polyphemus#/media/File%3AAntheraea_polyphemus_eggs_sjh.JPG

 

Tiny yellow caterpillars will hatch about 10 tens after the eggs are laid. They will feed for 5-6 weeks on the host plant and can grow three to four inches in length and 3/4 inch in diameter.

https://en.m.wikipedia.org/wiki/Antheraea_polyphemus#/media/File:Antheraea_polyphemus_1st_instar_sjh.JPG

These caterpillars molt five times, the fifth stage being the pupa, before they turn into an adult.  In the firth stage or instar, caterpillars eat a tremendous amount.

Cocoons are made out of brown silk, hence why they are called silk moths.   Once the adult moth hatches from their cocoon, they have to pump up their wings up with fluid.

If the moth is a female, she will emit pheromones which the male moth can find with his large comb like antennae.  A male moth can fly for kilometers to find a female.

Once the moths have mated, the female will spend most of her time laying eggs where as the male may go off and mate again.  Polyphemus moths have vestigial mouths, which mean their mouths have become smaller and they do not eat.  Adult polyphemus moths live less than one week before their live cycle ends.

What do adult polyphemus moths look like and where can you find one?

Adult Polyphemus Moth Description

Polyphemus moths adults are giant silk moths that have a wingspan of 10 – 15 cm wide.  As you can see from the photograph, the wings are a variety of earth tones including shades of gray, light brown, reddish brown and yellowish brown.  The upper wings have smaller transparent eyespots, where as the large hind wings have large eyespots outlined with yellow, white and black rings.  It is noted that there can be considerable variation in different specimens, even from the same area.  The underside of the wings can range from pinkish-white to various shades of brown.

The colouring and markings on the polyphemus moth are defense mechanisms which protect it from predators.  The deceptive and blended colouration with startle patterns help the moth to be camouflaged.  The large eyespots, on the polyphemus moth’s hindwings, are a distraction display, which confuses or distracts predators by resembling the head of a great horned owl.

 

Where do polyphemus moths live?

Polyphemus moths live here in Victoria, BC!  They also can be found in other parts of southern Canada all the way down into Mexico.  The only lower states they are not found in are Arizona and Nevada.

Video Editing

Today we learned how to work with imovie through MAC computers. I have had very little experience on this subject so it was a slow process for me. In the beginning I was overwhelmed trying to figure out what to do, but after some time I became a little more comfortable.  I loved seeing the other videos that students have produced in the past, and seeing how creative and humourous Jamie was in class today with his goat movie.  Thankfully Jamie showed me a few tips which gave me more confidence to play around and see what I can come up with on my own, so thanks for that Jamie!!

I can see how using different types of videos can be a huge asset for teaching.  For example slow motion video can allow us to see what we can’t see with our own eyes such as a horse and how it runs, or it can speed up what we are seeing so that we can understand the process more easily such as a caterpillar making a cocoon.  For my own art instruction I can see that video would be an asset for demonstrations of art projects and making it accessible for students all around the world.

You can find the resources from Rich available at the following links:

How can we tell if a polyphemus moth is male or female?

You can tell if a polyphemus moth is male or female by carefully looking at the comb-like antennae to see if the antennae are large which is male, or small which is female.

Out moth’s antennae are quite small so I determined that it was a female. See photo below.

Looking at Twitter, Trello and Open Source Educational Resources

During this class we reviewed Twitter and Twitter Deck.  This week I went on to my Twitter account and I was blown away by the information and connections I can make through this tool.  During our seminar class  on Wednesday this week Kristin Holland came and spoke and talked about story workshops, which I was very curious about.  I saw a tweet come up, so I clicked on it and was able to learn more about how to work with watercolours in story workshops! Wow, it look so interesting.  Here it is:

Today links were created by Michael as signing up tool for our inquiry project.  Again, I had not thought of this as a teaching tool, but all of the students in the room were able to type on to the document at the same time as it was projected on to the big screen.  There are pros and cons to this method as everyone can change everything in the document, but I think it is an exciting tool to know about.

Open Educational Resources were reviewed and the options are endless for teachers to use these free teaching tools to build curriculum and support learning, but I must say it is overwhelming to know everything that is available and how to use it.

Copyright has always been something that I care about as an artist so it was interesting to review it in class.  It was interesting to me that copyright now has other options that weren’t available even a few years ago, like creative commons.  These options allow me to really think deeply about the images I put online and how I will present them for the public to use or not use.

Here are the slides from this class: https://edtechuvic.ca/edci336/2019/09/24/slides-from-week-three/

Where does the name polyphemus originate from?

The scientific name of this magnificent large silk moth is Antheraea polyphemus (Cramer). The name originates from Greek Mythology from a giant cyclops named polyphemus who had one big eye in the middle of his forehead. The large eye shapes found on the hind wings are similar to a Cyclops eye, hence the name polyphemus.

Free Inquiry: Polyphemus Moths

Polyphemus moth – photo by Jessica Milne in Victoria, BC

These moths live in our backyards here in Victoria, yet how many people know about them? A friend of my husband’s came over one day in the late summer of 2009 with a huge, bright green, beautiful caterpillar in a jar, wondering what it was. My husband (an entomologist) didn’t know at the time but was interested, so we kept it. Before the end of the day, the caterpillar had already made itself a cocoon and was gone from sight. Months passed and we forgot it was even there. The following spring, I put the jar with the cocoon in it outside as I thought it was probably dead. To our surprise, a big beautiful moth appeared! I have never seen anything like it before in my life. What was this beautiful creature? So far my husband and I figured out it was a polyphemus moth, but I don’t know much more than this.

This inquiry will reflect what I learn about polyphemus moths and how they are different than other moths and butterflies.  Along with the information I find, I will also explore the polyphemus moth life cycle through drawing and painting and possibly video to further my knowledge of these wondrous creatures.

Luckily for us we also found a polyphemus caterpillar in Ontario last summer that also created a cocoon for us to watch and wonder about.  See photos below:
