I’d like to tell you a crime story. At least, it would be a crime story if told from a human perspective. But is it still a crime story if it’s about the natural world? I’ll tell it and then let you decide for yourself.

First let me set the stage: Not long ago I was hiking in Northern Utah’s Bear River Range. It was the height of wildflower season, and I was enjoying the colorful variety of blossoms along the trail. I stopped to admire a tall, showy plant with dozens of purplish-green blossoms: Frasera speciosa, commonly known as monument plant or green gentian. It’s often seen near the top of Logan Canyon, but what struck me about this particular monument plant was that it was full of bumble bees.

I knew that a Utah-based conservation science organization, Sageland Collaborative, is asking community volunteers to help them measure bumble bee diversity in the state, so I took out my phone and snapped a few photos. Later I uploaded the best photos into an app called iNaturalist so they’d end up in the Utah Pollinator Pursuit database maintained by the Utah Division of Wildlife Resources with Sageland’s help. Then I waited to learn what species of bumble bee I’d seen. The answer came back: indiscriminate cuckoo bumble bee. I thought: What an unusual name. I needed to know more.

It turns out “indiscriminate” simply means that, unlike many native bees that are particular about what they eat, this species doesn’t much care where it gets its nectar. As for “cuckoo”? Like the birds they’re named after, these bumble bees are thieves.

Or to say it more scientifically: these bumble bees are kleptoparasites. Parasites – animals that take resources they need from other species to the detriment of those species – and “klepto,” as in stealing. Like cuckoos or cowbirds, they lay their eggs in the nests of other bumble bee species, letting the workers from the host species do the work of raising them.

Here’s where our crime story gets even more sinister. When a cuckoo bumble bee queen finds a suitable nest to rob – one with a good-sized group of workers to raise the bee larvae, but not so many workers that they can easily protect their queen – she kills the host queen and becomes part of the colony, laying her alien eggs for the host workers to feed.

Cuckoo bumble bees don’t need their own workers, so they’re less often seen on wildflowers. In fact, there’s a good chance that some of the other bumble bees on my monument plant – the ones I didn’t get a picture of – were members of the host species. They also don’t need to take pollen back to a nest of their own, so they don’t have those “pollen baskets” we often see on the hind legs of female bumble bees.

But they do move pollen from flower to flower when it sticks to their bodies as they feed. In other words, they do play a role in sustaining the wildflowers we enjoy every summer. So is this really a crime story? Or is it just another example of the amazing diversity of behaviors found in nature? While you’re deciding about that for yourselves, I hope you get a chance to enjoy watching Utah’s various kinds of bumble bees as they do their all-important work.

Tigers

The year of the tiger. Our mountains, canyons, and valleys are replete with tigers-there’s no escaping them, tiger swallowtail butterflies! Even my grandkids captured one, which entertained them for days. It had a damaged wing and preferred crawling to flying. It’s angelic beauty transfixed the onlookers. Although injured, it hung on for a week- about the average life span of an adult butterfly.

The normal range of the western tiger swallowtail covers much of western North America, from British Columbia to North Dakota in the north to Baja California and New Mexico south. Individuals occasionally turn up in eastern North America, though it is generally replaced by the similar eastern tiger swallowtail.

Western tigers emerge from winter chrysalids between February and May, the date depending on the temperature. They are seen earlier in the more southerly and coastal parts of their range. These are high energy butterflies, rarely seen at rest.

The females lay up to a hundred eggs on a wide variety of host plants including willows, aspens, ashes, poplars, alders, and cottonwood. The eggs are deep green, shiny, and spherical. They are laid singly, on the undersides of leaves. The caterpillars emerge about four days later.

The caterpillars molt five times, eventually reaching a length up to 2 inches before pupating to adults. In summer, the butterfly can emerge as quickly as 15 days after the caterpillar’s pupated, but when the caterpillar pupates in the fall, the butterfly does not emerge until the spring. For camouflage, the young caterpillars, strangely resemble bird poop as they hatch. Once they begin to molt, they turn bright green in color, with large, yellow eyespot marks studded with black and blue pupils. These fake eyes may frighten predators, along with retractable, iridescent, horn-like structures on their head.

To harvest nectar, a butterfly unfurls its proboscis, a tube that functions like a straw and is coiled below the head when not in use. It inserts the proboscis into the flower and sucks up nectar by rhythmically contracting the muscles in its head. Sugars in the nectar provide energy for flight, defense, reproduction, and other daily activities.
Tigers also obtain nutrients and replenish fluids through “puddling,” where they congregate in large groups on mud or wet sand around puddles, streambanks, or on piles of fresh manure. I’ve observed puddling many times, always a levitating experience! Here they take up salts, proteins, and minerals. Salt is scarce in the butterfly diet, but is essential for reproduction and flight.

Puddling is primarily a male behavior, and during mating, a male butterfly transfers salt to the female in a sperm package, which she incorporates into her eggs. Researchers have found that sodium increases reproductive success in some butterfly species. During puddling, groups of males are conspicuous to females seeking mates. Males also patrol at treetop level looking for mates, swooping down to intercept females.

Thus, if you see a tiger, don’t be alarmed, just relax and enjoy their exquisite beauty and fascinating behaviors.

The Bees and the Birds

March is a thrilling month to be in an elementary school. Besides fifth grade maturation sessions, shamrocks pop up and many spotlight the impact of Dr. Seuss. Besides green eggs and ham eaten by children wearing tall red and white hats, we read and re-read books filled with fanciful characters and rhymes that roll off the tongue. I learned this year along with my students that Dr. Seuss’s father was the superintendent of parks in Springfield, Massachusetts, so naturally young Theodor took his sketchpad and pencil to observe and record whenever he could. When an animal lost an antler at the zoo, he would use it to craft a sculpture just as whimsical as the imaginative ones in his books. He called them pieces of The Seuss System of Unorthodox Taxidermy and placed them early in his career as promotional advertisements in bookshops. Kangaroo Bird with its teal stripes and pouch-perched hatchling and the Andulovian Grackler’s fur tufts and orange bill intrigue me. He also painted the stunning “The Birds and the Trees” featuring a white flock flying between red and pink palm trees that inspired the Dadake Day in “Oh the Thinks You Can Think.” As we studied Dr. Seuss’s “Did I Ever Tell You How Lucky You Are?” released 50 years ago this year, students noted how many birds appeared in the pages, leading us to do a Seuss bird scavenger hunt, our version of the birding counts chronicled in Mark Obmascik’s “The Big Year: A Tale of Man, Nature, and Fowl Obsession” (that’s f-o-w-l).

I do know I was lucky to teach once on a fifth grade team with a man students called Mr. J. Among many other things, he taught them how to recognize and identify birds. He preserved a time each day to review birds they had learned and add facts about a new species, how it looks, how it sounds, and how it behaves. He could display photographs and even silhouettes; students knew the shapes enough to identify them. He could play short audio clips, and students shouted out the corresponding birds too. I’ve discovered since The Bird Song Hero app that provides a spectrogram showing pitches visually that allow people like me another way to memorize those various bird songs. I remember I popped in the day they were discussing how our loggerhead shrike impales insects, rodents, snakes, and lizards on fences and really anything sharp and off the ground. When we took them on the bus through the Bear River Migratory Bird Refuge, I couldn’t believe my ears as kids with binoculars and without them were confidently shouting, “I see…” and tallying on their clipboards. For weeks that spring I would find students at recess peering up in the sky above the schoolyard doing the same thing. When I marveled at this phenomenon, Mr. J. smiled. “You know, Shannon, it isn’t about the birds. It’s about being aware.”

So often his “It’s about being aware” mantra pops in my head, like it did this week when my students huddled around our class pet cage housing a bee that emerged early from my Crown Bee tube “free-bee” from a recent science-teaching conference. Just like Dr. Seuss’s Bee-Watcher-Watchers, these six- and seven-year-olds eagerly missed romping in the fresh powder playground to watch a bee perched on a strawberry. I’ve done the same thing, standing mesmerized, lost in thought, watching a bee on a western coneflower, repeating the Seuss rhyme “Just tell yourself, Duckie, you’re really quite lucky.”

You and I and the Winged Things

One of the greatest magics of these late autumn evenings is that of midges, gnats, flies, mosquitoes, and bugs which flitter about in the humble stratosphere of their world between the intermittent cold snaps. They loop and spiral, as if on spiritual roller coasters, gently refracting the setting sun through and upon their bodies so that they seem to glow and become prescient of the night’s stars soon to bloom. When the cool November sun begins to set low, I can look out amongst the naked shrubs and thinning trees, the tall shaggy grasses and dead kaleidoscopic leaves, and see those hidden creatures who only dance in unlovely places the splendid slow waltz of autumnal joy.

Through the cascading shadow, the dance of the waning wing-bearers becomes even more dramatic. As the sun continues to slide below the mountains, the insects increase their pace it seems, and then begins the cataclysm of the birds. Small gray and off-gray birds with different flecks, inflections, songs, and hearts, though unified as the kind that would easily build a good hardy nest in an old dilapidated mug, begin diving through the midges and gnats and flies and mosquitoes. The birds are trapeze artists. Starting from a perch in a nearby tree, they swoop with grace through the air in a dramatic arc. At the nadir of their swing, the snare roll abruptly halts, a sharp inhale of silence descends like thunder and is followed in quicktime by a cymbal crash as the acrobats catch their purse in midair. Then, gently arching back up to the adjacent branch across, a great applause raptures. Like this, the birds dive and breach, avian orcas earning their rich protein in preparation for the imminent changing of the season. The horizon of thin times drives the orchestra of life onwards.

As I watch the fading insects, bugs, winged things, and other wonders I ponder as to why many see them as pests. In the evening glow, it seems an impossible identity for these fellow inhabitants of our world. Do people fear them? Not understand them? Believe they belong in one place and not another? Watching them in that moment, the thought escapes my mind and I am glad. I am glad to forget their supposedly assigned state, and I instead reforge my memories anew in the present, watching them as sparks in the swiftly quenching day. The perpetual creation of the world continues along, with I and you and all we’ve ever known and will know wrapped within it.
