Whenever I give a talk on dragonflies, I point out that there are two subgroups to the order Odonata. The dragonflies (anisoptera, which means “same wing”) and the damselfiles (zygoptera meaning “different wing”), which I am told refers to the sizes and shapes of the front and hind wings. I guess because they’re bigger and […]

HumBug: Good Mothers
In grammar school I learned that only the birds and mammals cared for their young. Later I learned that crocodiles and alligators build and protect nests, but largely the “lower lifeforms” do little after laying their eggs. Aside from the social insects that feed, protect and rear the young into adulthood, parental care is relatively rare […]

HumBug: Yellowjackets
Once, while recovering from shoulder surgery, I heard my wife scream from the backyard. Arm immobilized with a brace, I stumbled outside. She was under attack from dozens of yellowjackets. Before I could get her away from them she had accumulated nine stings. The scars she got from accidentally disturbing a nest in the ground […]

HumBug: The Most Unlovely Insects
Butterflies and dragonflies can entrance us with their beauty. Praying mantises carry themselves with a slender, lethal elegance. At the other end of the insect spectrum, you can find the order of flies. Unlike all other winged insects, members of the order Diptera have only two wings not four. Di meaning two and ptera meaning […]

HumBug: Flying Rods
The Van Duzen River provides me with endless things to see, photograph and ponder. In my excursions I have never once been disappointed. A while ago I watched a “hatch” of Mayflies (order Ephemeroptera) flying upstream against the gentle breeze following the river. There were hundreds in view and I could imagine how many there must […]

HumBug: Tiny and Primitive
If you have sharp eyes or good glasses, pick up a potted plant and you might see a tiny gray thing, not much larger than the period at the end of this sentence, scurry away or even leap. This particular kind of critter has been hiding under rocks for a very long time. These are […]

HumBug: Artful Dodgers
Today, faced with the humdrum task of taking old stuff out to the compost bin, I grabbed a camera on the off chance I might see something more interesting than rotten potato peels. Flying low and fast, dodging between grass stalks and tangled branches was a Common Whitetail (Plathemis lydia). With their dark wingspots, agile […]

HumBug: The Sister and the Admiral
Out in my back yard I saw a butterfly flying low, straight and fast, too fast to identify perfectly. It landed half way up a redwood tree and proceeded to open and close its wings, displaying its striking markings, still too far away to identify perfectly. That’s because there are two species of similar size, […]

HumBug: Solitary Wasps
Working in my garden, I noticed a small blue black wasp flicking its shiny wings as it dashed across the dirt, searching here and there. I can hazard a guess as to what it was looking for: a spider. Much has been written about the social wasps and their organization, diligence and sacrifice for the […]

HumBug: The 40-year-old Mystery
When I was in the Navy I never minded midnight topside watch on the ship I was on in Long Beach. I’ve always loved glow-in-the-dark things, and I never tired of looking into the faintly luminous blue fire swirling in the warm bay waters. That was before the Internet and Wikipedia, so my options to […]

HumBug: Tigers by the Tail
Looking out my window today I saw a happy and familiar sight, the instantly recognizable large, yellow and black striped butterfly, the Western Tiger Swallowtail (Papilio rutulus). The family papilio includes the zebra, black, spicebush, anise, pipevine and pale swallowtails. The tiger is the largest and most common of them all with a wingspan of […]

HumBug: What’s Up, Tiger Beatle?
One of my favorite beetle species is out and about now. You might see them by the dozen hunting on sandy stretches of river bar. Cicindela oregano, commonly known as Western Tiger Beetle. About half an inch long and gray, they dart here and there and are among the fastest running creatures for their size. According to […]
