Katy lied.



  
                   Katy lies
                   You could see it in her eyes
                   But imagine my surprise
                  When I saw you
                                 —Walter Becker/Donald Fagan

     Amazing how a word can slumber at the back of your brain for years, for decades, only to leap up, ready for duty, when the moment calls for it.
    "A katydid!" I cried, spying the gorgeous specimen atop my storm door when I returned from taking Kitty on her nighttime stroll a week ago Sunday, perching prettily atop the five coats of marine spar varnish.
     A round-headed katydid, I think. One of the 14 species of amblycorypha. 
     Not very well camouflaged in this context. Taking a risk to closely inspect my work. Nor am I 100 percent sure it's a katydid — it could be a false-leaf grasshopper — the decisive head is a bit tucked down. Though now that I look at it, it does seem a little grasshoppery.
     Either way, you have to admire the way the camouflage leaf on its back includes the veins of the leaf — details are important in any deception. An art form all their own. Vladimir Nabokov, a devoted butterfly lover, savored this sort of thing. "The mysteries of mimicry had a special attraction to me," he wrote. "Its phenomenon showed an artistic perfection usually associated with man-wrought things. . . When a butterfly had to look like a leaf, not only were all the details of a leaf beautifully rendered but markings mimicking grub-bored holes were generously thrown in." Details no predator would ever notice, Nabokov cooed.
      The next morning, I spied a monarch flitting about a milkweed — they lay their eggs in milkweed. I couldn't get a good photo, I'm afraid, as the beastie was instantly on the wing. 
     But it does lead to an interesting question: two insects, both trying to survive, one by hiding, the other by advertising itself boldly. What's the difference? The katydid would make a tasty snack, while the monarch is poisonous, like the milkweeds it feeds upon as a caterpillar. So the bright orange and black coloration is a big lepidopteral "fuck you!" to potential predators. "Go ahead, eat me. It's your funeral."
     Which has to be encouraging to us toxic, out-in-the-open sorts. Leave hiding in the shadows to others, the timid leaf munchers. Fear nothing; our poison protects us.
      When I opened the screen door, the katydid oafishly moved to the lip of the door frame, where closing the door would crush it. Good thing its ancestors cooked up that leaf disguise, over countless millennia, and willed it to their progeny, because they're not very bright, the trademark curse of heirs and legacies everywhere. Kind soul that I am, despite my venom, I shooed it away and let it live to hide for another day.

  1. I was walking the dogs with my spouse in Steel workers park along Chicagos south lakefront when I noticed a copious amount of dragon flies this past weekend . Turns out they are in migration. Quite the treat

    1. Received a photo from San Felipe in Baja this morning, from a friend at water aerobics. While the women seem uninterested, a dragonfly with a green body and blue tail took a liking to him.

  2. I assume the Nabokov quote comes from the recent New Yorker "animal" edition. If so, Nabokov goes on to express doubt that the "artistic perfection" was evolutionarily derived, because "no predator would ever notice." A challenge to Darwinists and Mendelians, I suppose.

  6. Monarch butterflies do not feed on milkweed plants. They lay their eggs on them and monarch caterpillars eat the milkweed ( exclusively ) until they make their chrysalis.

    1. Right you are. I've adjusted the text accordingly. Thanks.

  7. I hate the thought of killing any living thing…that is, every living non-human thing.
