    Back in the late sixties, I saw fire-flies on the south end of Midway, Ut.

    There is a place near Redstone, CO that is supposed to have fireflies that are not found anywhere else. I've never seen any kind of fireflies in UT or CO, but I'm glad they are furnishing a science experience for those who are lucky enough to see them. FUN.

    During WWII, the family lived in Nashville, Tennessee. One night my brothers and I caught a couple of Mason jars full of fireflies and took them to our room. Later, my brother was leaning out of the window talking to a couple of neighbor kids. A warden came by and threatened to turn us in for violating the black-out. He would not believe the light was from a couple of jars of fireflies. We had to cover up the jars.

    We had them in our yard in rural Duchesne county, more than 10 years ago. Wonderful to watch.

    I've worked as a software engineer on projects in every area of the U.S. While working in the Southeast, particularly Florida, Kentucky and S. Carolina, I very much enjoyed seeing them in the late dusk and evening. Just fascinating to watch and try to track them as they flickered in and out of sight. Now that they've been sighted here, though only very rarely, I look forward to being one of the lucky few to see them Utah.

    We get hundreds in our yard here in VA every summer.
    As a biologist I have to say that magnesium and oxygen are not enzymes, as the article may lead you to believe. An enzyme called luciferase is used in light production, which may indeed require magnesium and oxygen (but they are not enzymes). Luciferase has the same root as the name Lucifer, meaning "light bearer."

    I found your article on firefly a very interesting, particularly that you mentioned they had not been found in Utah for many years. As a young boy in rural utah over 50 years ago we used to catch fireflies regularly. We enjoyed them then and find it interesting that they are being studied more now. We have also seen fireflies while backpacking in Southern Utah in the past few years. Thank you for the article.

    That is too kool, I haven't seen bioluminescent fireflies in a long time and never in Utah. Now I'll have to look for them!

    Maybe it should read "mix two enzymes that contain the elements magnesium and oxygen" instead of "mix the two enzymes magnesium and oxygen". I'm pretty sure that magnesium and oxygen are not enzymes.
