Monarch Butterfly Tagging – submitted by Kent Cheesman

We are tagging the monarch through a program call Monarch Watch which is a nonprofit education, conservation, and research program based at the University of Kansas that focuses on the monarch butterfly, its habitat, and its spectacular fall migration.

This year our school has raised over 120 Monarch larvae. To date we have tagged and released 92 Monarch butterflies. Many students are intrigued by the program and have been contributing with larva found at home, providing milkweed to feed the larva and providing oranges and flowers for the Monarchs when they emerge from their chrysalis until there are released.

This endeavour has provided many educational pluses as students are very interested in the life cycle of not only the Monarch butterflies but also the many other “critters” they are finding and researching throughout our school yard. It has also been the starting point for many related classroom inquiries and writing activities as well.

Thanks so much for sharing Kent

Why Don’t Birds Lay Square Eggs?

What is ”egg-shaped” even? I used to think it was the shape of a chicken egg. Then one day I saw a collection of eggs from lots of different bird species, and I realized just how many different kind of egg shapes there really are! I had to know why. And it turns out a couple teams of scientists had wondered the same thing. Here’s what science says about why eggs are egg-shaped, if that’s even a thing, which I’ve learned it might not be. Evolution of bird eggs, go!

Images from a Cell Phone Camera – submitted by Dave Gervais

This is an image of an insect taken from a Huawei p 30 pro cell phone camera. When I compare that to images that I took in 1978 using a really good dissecting microscope with an optical camera, this is incredible. I could easily take these images and identify this insect using a good dichotomous key.

The cost for this cell phone camera is comparable to that of a good dissecting microscope attached with an optical camera, around $ 1400 dollars. Either just with the cell phone, or equipped with the hand held circular motion free tripod, this device could greatly improve field trip images without the need to take specimens back to the lab. What a great purchase for a science department!

 

Question:   Can you identify this insect from the banks of the Ottawa River?  Send your answers to info@stao.org, attention safety committee. Answer will be posted next week.
