    Millipede season

    By / October 27, 2012

    It’s millipede season again here in Boca, although down in the Keys, it started back in August. Don’t worry, though; they’re no threat to your health or safety. From the UF/IFAS factsheet ENY-221/IG093 (available on their website): Centipedes and millipedes are commonly seen in yards and occasionally enter homes. Neither centipedes nor millipedes damage furnishings, homes,… Read more

  • Happy Leap Day 2012!

    By / February 29, 2012

    Today is the day that, according to our modern (Gregorian) calendar, we insert an extra day in every year evenly divisible by four, except for centennial years unless divisible by 400. We do this because the earth’s revolution around the sun and its rotation on its axis are independent (the solar system didn’t require that… Read more

  • You say you want a revolution?

    By / January 6, 2011

    If your New Year’s Resolution had anything to do with precision in language, and you have any interest in astronomy, please try to remember the difference between the terms revolution and rotation. The Earth revolves around the Sun: It takes a year to do this. In fact, the Copernican Revolution made famous by historian of… Read more

  • Another darner from a couple of years ago

    By / September 9, 2010

    Going through my old photo files has been fun for me; last night I found a slightly better photo of Coryphaeschna ingens, the Regal Darner [UPDATE:Gynacantha nervosa, Twilight Darner] who visited us during Tropical Storm Fay. I also ran across a couple of untagged photos of other species that I knew I’d seen, but couldn’t… Read more

  • Florida Word of the Day: Ligule

    By / March 25, 2010

    In writing the post on hastula, I found out that a hastula is like a ligule. Which  I guess is fine, as far as that goes, but really, it doesn’t go very far with me. I, after all, am neither agrostologist nor graminologist, so I had no idea what a ligule might be. According to MW,… Read more

  • Florida word of the day: psammophyte

    By / February 26, 2010

    Psammophyte. This seems to be a fancy way of saying seaweed. Since this word is too hifalutin’ for the American Heritage or even Merriam-Webster teams to take on, here’s a definition of the term from Dawes and Mathieson (Seaweeds of Florida, U of Florida P 2008): A plant that grows in unconsolidated sediments or on… Read more

F. Rein> <what… Read more

  • Day 20 moon

    By / February 4, 2010

    The last week of the lunation is turning into a test of endurance. Waking at 3 a.m. to get moon shots is not ideal for those of us who have day jobs. On the plus side, though, I have upgraded to CS4 and am able to annotate the photos; I’m working on the backlog and… Read more

  • Word of the day: irrupt

    By / January 5, 2010

    Today’s word is irrupt. It’s not just an alternative spelling of “erupt”; it has a specific meaning in ecology. Merriam-Webster’s 11 team defines it as follows: ir•rupt vi [L irruptus, pp. of irrumpere, fr. in– + rumpere to break — more at REAVE] of a natural population : to undergo a sudden upsurge in numbers esp….
