Las luciérnagas encuentran el amor en Utah

Mi nombre es Kate, y me llamo Carlos, y hoy este Wild About Utah está en español e inglés. Esta historia también, se puede escuchar on line en UPR.org

Contra todo pronóstico, las luciérnagas encuentran el amor aquí en Utah. En lugares como el Parque de las Luciérnagas en Nibley, puedes ver estas deslumbrantes linternas bailar y rebotar a partir de principios de junio. Ver estas luciérnagas es mágico, aún más cuando sabes lo que les costó brillar cada noche.

El primer desafío que enfrenta una luciérnaga es encontrar un buen hábitat húmedo aquí en el árido Utah. Encontrar un hábitat oscuro y húmedo puede ser difícil, pero de alguna manera las luciérnagas lo han logrado y lo han hecho en Utah desde posiblemente 1929. Una vez que una luciérnaga encuentra un buen lugar, ahora tienen que encontrarse entre sí. Hacer esto requiere precisión y química. En su linterna abdominal, la enzima luciferasa debe abrazar tanto la luciferina como una molécula de energía estrechamente para ayudar a combinar sus partes.

Luego, la luciferina se combina con oxígeno para formar la energética oxiluciferasa. Al igual que un niño con demasiados dulces, la oxiluciferasa ahora está desesperada por liberar algo de energía antes de que sea demasiada. Esto lo hace liberando un fotón que emite luz y vemos la magia ante nuestros ojos. Como si crear luz dentro del cuerpo no fuera suficiente, ahora deben ajustar su señal a su especie y encontrarse entre sí. Cada especie tiene un código morse único de luz que necesitan parpadear para encontrarse.

Ahora, digamos que una luciérnaga llega a un hábitat pantanoso y conoce al amor de su corta vida de 3 semanas, ahora puede comenzar el romance. Los machos y hembras copulan durante horas, permaneciendo quietos y pegados de extremo a extremo. Durante este tiempo, el macho le da a la hembra lo que se llama un regalo nupcial lleno de proteínas junto con su esperma. ¡Si eso no es romántico, no sé qué lo es!

Las hembras almacenarán este regalo y lo digerirán durante varios días para ayudarla a obtener las proteínas necesarias para poner sus huevos. Una vez puestos, estos huevos tardarán entre unos pocos meses a 2 años en convertirse en adultos, donde iluminarán su corazón para repetir el proceso.

Para mi entender la naturaleza y los pequeños detalles de ella me llena de satisfacción, el saber que es tan perfecta. Esa pequeña luz llena esperanza, nos muestra que el mañana sera mejor.

Mi nombre es Kate y me llamo Carlos y estamos locos por Utah.

Fireflies Find Love in Utah

My name is Kate and my name is Carlos. Today’s Wild About Utah is in both Spanish and English. The Spanish version will be read by Carlos Ramos. You can also listen to this story in Spanish this Wednesday evening between 9:01-9:06 or online.

Against all odds, fireflies find love here in Utah. Out at places like Firefly Park in Nibley, you can watch these dazzling lanterns dance and bounce, starting around early June. Watching these fireflies is magical, even more when you know what it took for them to glow each night.

The first challenge a firefly faces is finding a good wet habitat out here in arid Utah. Finding dark, wet habitat can be tough, but somehow fireflies have done it and have done so in Utah since potentially 1929. Once a firefly finds a good spot, now they have to find each other. Doing this requires precision and chemistry. In their abdominal lantern, the enzyme luciferase must hug both luciferin and a molecule of energy tightly to help combine their parts. Then luciferin combines with oxygen to form the energetic Oxyluciferase. Much like a kid with too much candy, Oxyluciferase is now desperate to release some energy before it’s too much. It does this by releasing a light-emitting photon and we see the magic before our eyes. As if creating light inside one’s body wasn’t tough enough, now they must attune their signal to their species and find each other. Each species has a unique Morse code of light they need to blip in order to find each other.

Now, let’s say a firefly makes it to a marshy habitat and they meet the love of their short 3-week life, now the romance can begin. Males and females copulate for hours, remaining still and stuck end to end. During this time, the male gives the female what’s called a nuptial gift full of protein along with his sperm. If that isn’t romantic, I don’t know what is! The females will store this gift and digest it over several days to help her get the protein to lay her eggs. Once laid, these eggs will take between a few months to 2 years to become adults where they will light their heart out to repeat the process.

For me, thinking about all the chemistry involved, both molecular and romantic, is moving. I hope we can protect their light for generations to come.

My name is Kate and my name is Carlos and we’re Wild About Utah.

Cuckoo Bees

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.

I’m Mark Brunson, and I’m wild about Utah’s native bees.

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.

This is Jack Greene for Bridgerland Audubon Society, and I’m wild about Utah, and its puddling tigers!!
