  • The Bog of Doom off of State Route 199.

About two hours north of Eureka on State Route 199, a few miles past Gasquet, a small sign announces “Botanical Trail.” It's a very short drive on a good gravel road to the parking area. A little walk on the well-marked trail puts you in the middle of a Darlingtonia Bog. Here, where soggy conditions and serpentine soil discourage most plants, is the ideal habitat for California's signature carnivorous plant, the cobra plant (Darlingtonia californica), aka California pitcher plant, aka cobra lily. It's not truly a member of Liliaceae.

HumBug: Dining Out in June

  • Wear on this Anax junius' wings hint it's had an adventurous journey.

The fifth of June invited me to take my favorite stroll along the Van Duzen River. Things are at last heating up in the insect world.

While I was checking out some daisies, a shadow flitted past me. It was member of the well-known migratory dragonfly species, the common green darner (Anax junius). This is the first one of these I've seen this year. It is one of the largest dragonflies that frequents our area. Wear on its wings hints that it has travelled far. I reported the sighting to the Migratory Dragonfly Partnership, a citizen science project coordinated by the Xerces Society. The partnership collects sighting data on this and four other species of known migrators to better understand this behavior.

HumBug: A Walk in the Woods

When I looked out today the sun was shining and the bugs were out. I set my computer and camera to acquire a stack of photos of a snail hunting beetle I'd collected on a late night walk, and out the door I went.

I managed to identify four different species of butterfly and the first Lorquin's admiral (Limenitis lorquini) of the season. They will set up a perch and defend their territory even rising to chase away birds. There were several painted ladies, an anglewing and a California hairstreak (Satyrium californica).

HumBug: A Patch of Daisies

Driving along U.S. Highway 101 lately, you see patches of newly emerging ox-eye daisies (Chrysanthemum leucanthemum). As idyllic as they might seem from a distance, there's a lot going on up close. This European species was introduced to North America in the 1800s and has become widely naturalized. Although considered an invasive weed by some, their seeds are often included in wildflower mixes.

HumBug: The Bald Faced Truth

I decided to devote this week's contribution to a single unpopular species. Known for its large size, aggressive behavior and powerful sting, the bald faced hornet (Dolichovespula maculata) is liked by few people. They're neither completely bald faced nor technically hornets. Their white faces are sparsely covered with setae (hairs) and they are, in fact, the largest member of the yellow jacket clade of wasps.

When I spotted one building a slender, gray stalactite from the ridge of my greenhouse, I knew it was preparing to build a nest. Instead of reaching for the wasp killer, I reached for a camera. I really wanted to find where she was gnawing the wood she ground into a pulp to build her nest. I was going to stain some paper with food coloring and try to get her to build a multi colored hive. Sadly, I never found the source of her building materials.

HumBug: Beetles in the Spring

While beetles were my first love when I started studying insects and are believed to have the greatest number of species of any of the insect orders, I find I seldom write about them. There are plenty to write about. The following are just a few I've seen in the last week.

Two years ago I wrote about the night stalking tiger beetle (Omus californicus), a nocturnal terror with a Darth Vader demeanor. That was the first one I'd ever seen, and I was impressed by its ferocious face. This year I've seen several both at night and in the daytime. Like their cousins within the family cincidela, they possess huge mandibles to subdue prey and with which the males hold onto their mates.

HumBug: Spring Bug Break

Spring is finally, really, underway. I took a walk along the Van Duzen River got nearly 100 photos of invertebrate wildlife. There were three different kinds of dragonfly: California darners, variegated meadowhawks and a single female red rock skimmer.

HumBug: New Neighbors

Late the other evening, my wife and I went out for a walk. Along the road we saw several large shiny brown millipedes. In the middle of the road, apparently investigating a smeared member of that species, was something that at first looked like a slightly smaller one. On closer inspection, it was something completely different. I didn't have a camera or a jar, so my very tolerant wife volunteered to stay and keep track the bug in question while I got something to collect it with. For the first time in years I actually ran (it was a short distance) and retrieved an empty spice shaker bottle. They're my favorite collecting vessel; made of tough of plastic they come in a convenient variety of sizes, are break-proof, clear and come with lids already perforated with air holes.

HumBug: Bugs Between the Raindrops

Despite the dreary weather, life must go on. Eager to get along with their lives, our local insects show up even for the brief patches of sunshine that occasionally grace my back yard. Mostly disdained by the local honeybees, oxalis, dandelions and English daisies draw a crowd.

HumBug: Partial Sun, Chance of Butterflies and Bees

  • California tortoiseshell populations fluctuate erratically.

Well, at least we had one sunny day. Along with the rest of us, the insects crawled from their hidey holes in bark crevasses, burrows in the ground and old wood.

A couple of days ago I got a brief glimpse of what I suspected was a California tortoiseshell butterfly (Nymphalis californica). Sometimes, for reasons that aren't clear, their population can explode. Some years ago I counted nearly 100 of them apparently migrating upstream along the Van Duzen River. On Thursday a dozen or so flitted about the plum trees in my yard. They were accompanied by nearly as many painted lady butterflies (Vanessa cardui), purported to be the most widespread butterfly in the world seen on all continents except Antarctica.
