First Release of 2023

Advice for releasing your monarch butterfly

MichaelStephenWills2 Comments

We let our first monarch butterfly rest overnight, until noon of the following day.

Pam did better with tracking the monarch’s flight, so I used video. Thanks Pam!

I delay butterfly release when:

  • the forecasted high temp is below 65° F (18° C) or 60° F (16° C) if sunny and calm.  When no other option exists, 50-59° F and sunny is borderline acceptable.
  • the forecast calls for rain.  A light rain is not a problem for butterflies with day-old dry wings, but it’s not a good release option for first-day newborns.
  • the butterfly emerges too late in the day.  I keep it overnight if the butterfly cannot get 3 hours warming of flight muscles in the sun.
  • there are storms in the forecast.  I wait when there are less than four (4) hours of good weather projected.  When extreme weather (like a hurricane) is forecast within twenty four (24) hours, I keep the butterfly safe until the storm passes.  Twenty four (24) or more hours should provide ample time to find shelter from the storm.
  • I am not sure about a release.  Keeping a butterfly overnight is acceptable. In fact, a butterfly’s wings are stronger on day two (2), providing better capability to escape predators.  A butterfly can easily hang from the mesh cage roof overnight. I do not worry about feeding a butterfly unless a second night of shelter is necessary.

As the moment of emergence approaches, the skin of a Monarch chrysalis becomes translucent to reveal the butterfly compressed into that small space.

First Emergence of 2023

Monarch butterfly and chrysalis

MichaelStephenWills3 Comments

Our grandchildren spent the day with us, the last week of their summer before school begins. This July I had improved on my Monarch collection from 2022, when 9 butterflies were released, by two (2) caterpillars for a total of eleven (11) raised over several weeks to the chrysalis stage. When leaving to pick up the children for an outing one chrysalis skin had turned clear, a sign the enclosed butterfly is close to emerging. We returned from an outing for lunch to find this chrysalis unopened, so we checked now and then for progress. Four hours later, just as their Mom arrived for them, the grandchildren and everyone witnessed this event. What luck!!

“Migrating monarchs soar at heights of up to 1,200 feet. As sunlight hits those wings, it heats them up, but unevenly. Black areas get hotter, while white areas stay cooler. The scientists believe that when these forces are alternated, as they are with a monarch’s white spots set against black bands on the wings’ edges, it seems to create micro-vortices of air that reduce drag—making flight more efficient.”

“Monarchs begin leaving the northern US and Canada in mid-August. They usually fly for 4-6 hours during the day, coming down from the skies to feed in the afternoon and then find roosting sites for the night.  Monarchs cannot fly unless their flight muscles reach 55ºF. On a sunny day, these muscles in their thorax can warm to above air temperature when they bask (the black scales on their bodies help absorb heat), so they can actually fly if it is 50ºF and sunny. But on a cloudy day, they generally don’t fly if it is below 60ºF.“

“Migrating monarchs use a combination of powered flight and gliding flight, maximizing gliding flight to conserve energy and reduce wear and tear on flight muscles.  Monarchs can glide forward 3-4 feet for every foot they drop in altitude.  If they have favorable tail or quartering winds, monarchs can flap their wings once every 20-30 feet and maintain altitude. Monarchs are so light that they can easily be lifted by the rising air. But they are not weightless. In order to stay in the air, they must move forward while also staying within the thermal. They do this by moving in a circle. The rising air in the thermal carries them upward, and their overall movement ends up being an upward spiral. Monarchs spiral upwards in the thermal until they reach the limit/top of the thermal (where the rising air has cooled to the same temperature as the air around it). At that point, the monarch glides forward in a S/SW direction with the aid of the wind. It glides until it finds another thermal and rides that column of rising air upwards again.”

Meadow Fritillary

An August morning

MichaelStephenWills6 Comments

The range of the Meadow Fritillary covers eastern British Columbia east through southern Canada and the northern part of the US to Newfoundland, south to north central Oregon, central Colorado, northeast Tennessee, and northwest North Carolina.

This species is found throughout the Northeast and New England. It is said to have significantly expanded its range southward in recent years. Adult Meadow Fritillaries feed on nectar from a variety of plants, including Black-eyed Susans, dandelions, and Ox-eyed Daisies.

The Meadow Fritillary’s flight pattern is usually described as rapid, low, and jerky.

This specimen was found among many others in a meadow of the Brock-Harvey Forest Preserve

Cochise Spring

ancestral Apache land

MichaelStephenWills3 Comments

Interstate 10 between Benson and Wilcox ascends through a field of enormous, eroded granite boulders. Off to the west are the Dragoon Mountains, otherwise known as “Cochise Stronghold.”

Informative sign at campsite

Starting from the campsite is the “Sky Islands Traverse” hiking trail, leading up into the mountains. I wandered from the trail to follow a dry streambed to this residual pool of water, the time being early spring, and this is what remained from the winter rains.

A single butterfly of the genus Anthocharis generally called “Orangetip” for the colorful upper wing tips. These exist throughout the world, here in Arizona they migrate across the desert, obtaining refuge and nourishment from “Sky Islands” such as the Dragoon Mountains

Goodbye for 2022

Our last Monarch for 2022

MichaelStephenWills12 Comments

We successfully raised nine (9) Monarch butterflies this season, leaving us feeling, “Let’s do more in 2023.” Today’s post cover is a portrait of the last. She flew yesterday, September 23rd, forty (40) feet up to the oak tree shading the back yard, lost to us in the leaves.

Her chrysalis is the second from right in the following family photograph.

Here are two videos of our last 2022 Monarch to emerge and the first.

Emergence of a Monarch butterfly from a chrysalis 4K UHD with relaxing music. A caterpillar attached itself with silk to hang by its two rear legs to transform to a green chrysalis. Fourteen days later the chrysalis shell becomes translucent. Inside the chrysalis the Monarch butterfly moves to shed the shell. The released insect’s abdomen pumps fluid, expanding the crumpled wings. The entire process takes twenty minutes, compressed in this video to about six (6) minutes.

As the moment of emergence approaches, the skin of a Monarch chrysalis becomes translucent to reveal the butterfly compressed into that small space.

A real time film of our first 2022 Monarch Butterfly emerging from the chrysalis, then expanding its wings in 4K UHD with relaxing music. The process takes twenty (20) minutes.

The butterfly emerges from the chrysalis about fourteen (14) days after setting. To the photographer needing to capture the moment a signal is the green, jewel-like chrysalis turns transparent, apparently darkening to reveal the compressed form of the butterfly. It can be hours before the insect breaks free, the Canon EOS 5D Mark IV dslr camera is used for this. I set it on a Manfrotto BeFree Carbon Fiber tripod (with ball head), a Canon EF 100mm f/2.8L macro lens for optics. The Mark IV has WIFI and HD video capabilities, so I connected the camera to an Apple IPhone 7 using Canon software. Monitoring the transparent chrysalis in real time, I continually reset the video from the IPhone until the butterfly emerged. I used AVS video editor software to produce the film for YouTube publication.

Monarch Ready to Fly

Five wait off stage for their turn to fly.

MichaelStephenWills1 Comment

This Monarch butterfly emerged from the chrysalis a few moments ago. A minimum of two hours is required for the wings to harden before release to the wild.

Five wait off stage for their turn to fly.

Rainy weather forced us to leave her resting a full 24 hours.

Here are two videos of a Monarch release from 2020.

Monarch Caterpillar to Chrysalis II

AKA the sixth moult

MichaelStephenWills

In my last series of “Monarch caterpillar transforming to chrysalis” time lapse photographs, the 30-minute time interval missed the moult. For this series, I set the Canon EOS 5D Mark IV to remote from a IPhone 7, tethering me to hanging around the house for an afternoon of waiting for the magic moment of “transformation” (more accurately called “the moult”), thinking through the nature of the moment.

A monarch caterpillar accomplishes seven body transformations shielded from view. Six within its skin: the first five retaining a caterpillar body configuration, the sixth transforming to chrysalis. For all six, an enveloping skin conceals the change. The same holds true for the seventh transformation. The chrysalis remains opaque green with bright gold spots until turning transparent after the transfiguration to butterfly is complete.

The sixth transformation happens when the fifth instar caterpillar, fully sated with milkweed, climbs to a perch, spins silk around a set of prolegs, affixing them from a horizontal surface from which to hang. For this set I captured the moult of two monarchs hanging side by side inside a mesh cage with an east facing window for light. Even though the day was sunny, with the f-stop set to the lens maximum (32) for the deepest field of view, ISO at 32,000 the energetic skin shedding movements of the chrysalis cause blurring.

For 10-12 hours of profound bodily configuration changes the hanging caterpillar hangs without movement. In the last image of this first set, the next caterpillar is blurred by initial moult movement.

My attempt to capture a video of the moult was frustrated by inadequate lighting, the result was too dark to use. I must solve this technical challenge as the motions of the chrysalis as difficult to believe without visual proof. That said, here is the second moult with the first completed moult in background.

An interesting fact is the caterpillar uses silk to attach the skin to a substrate for the first five moults to hold the skin back while it crawls out of the discarded skin. The first meal of the hatched caterpillar (first instar) is the egg, the shed skin is the first meal for instars 2 – 4. The shed skin of instar 5 drops from the chrysalis. This is why you should never remove a Monarch caterpillar from the leaf, as in doing so may hinder a moult in progress.

Monarch Caterpillar to Chrysalis

The caterpillar attaches itself to a silk pad from which it hangs.

MichaelStephenWills1 Comment

Here is a photographic Series of a Monarch caterpillar chrysalis transformation, a step in the life cycle of the Monarch butterfly. The caterpillar attaches to a silk pad from which it hangs. Underneath the skin, the caterpillar is transforming to the chrysalis. In these photographs the silk pad and chrysalis attachment from a previous transformation are in the foreground.

About 34 minutes transpired between the previous photograph of the caterpillar in “J” formation, attached and hanging upside down to the chrysalis. In this time the outer skin was shed, revealing the chrysalis.

On My Arm

Settled In

Misjudged by over an hour, I reached into the cage to allow the Monarch butterfly to crawl onto my hand for the first flight. Instead, it crawled up my arm and clung to my cotton shirt sleeve.

Monarch Emergence

Our Third Monarch this year

MichaelStephenWills7 Comments

Clinging to my sleeve, this newly emerged Monarch wings dried. It is a process of excreting the fluids pumped into wings, crumpled from folding within the chrysalis, to expand them. The clear drips of water on my arm are this fluid.

Click photograph for a larger view and use Ctrl-x to zoom in closer.

Here is a video from this year, a Monarch emerging from the chrysalis, then expanding crumpled wings. Notice, this butterfly has a problem: once emerged the butterfly swings back and forth continually as it clings to the chrysalis. While interesting to us, the movement is caused from a missing front leg. Monarch butterflies have four legs, this butterfly is missing the right front leg, the imbalance causes the swinging movement. Freshly emerged, a large, distended with fluid abdomen is prominent between small, crumpled wings. With time, the abdomen pumps fluid, expanding the wings. Over several hours the fluid runs from the wings and is expelled from the abdomen, as seen in the above photograph.
