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.

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.”

After reading a New York Times article with the sub-title “A beekeeper in Savannah, Ga., found what turned out to be a yellow-legged hornet. State and federal officials, along with academic experts, are working to eradicate the species” I spotted this wasp foraging our flowers in Ithaca, New York. Its yellow legs caught my eye, although the apparent size (seemed larger in article photograph) and face and body markings seemed different. Using an Apple Iphone 14 ProMax I captured three macros from different angles, I attached them to an email to the local Cooperative Extension office. They gave me a quick response, confirming my suspicion this was a different “yellow-legged wasp.” The agent suggested it might be a “paper wasp” and directed me to a Cornell site were, for a $25 fee, an identification could be made.
Instead, this morning I found “insectidentification.org” with an excellent search capability. Under “Bee, Ant, Wasp and Similar insects that can be found in the state/territory of New York,” the third row from top spotted an exact match being the only Yellow-legged native wasp. I am going to respond to the agent with this identification as others in the area may have the same question, given the name of the invasive wasp.
“It is the Yellow-legged Mud-dauber Wasp (Sceliphron caementarium), also known as Black and Yellow Mud Dauber, Black-waisted Mud-dauber. Of the Latin species name, Sceliphron caementarium, caementarius means mason or builder of walls.”
“These are solitary parasitoid wasps and build nests made of mud. The family of sphecid wasps collect mud balls at puddle and pool edges for constructing nests comprised of up to 25 vertically arranged, individual cylindrical cells. Frequently, nests are built in shaded areas inside formations that are sheltered from the weather or from other environmental elements. These sites may be naturally-occurring, or man-made structures. Some examples are: under and inside various types of bridges, barns, garages, open-air porches, or under housing eaves. A female might take only a day to construct a cell requiring dozens of trips carrying mud. Females will add new cells one by one to the nest after each cell is provisioned. They provision these nests with spiders, such as crab spiders, orb-weaver spiders and jumping spiders in particular, as food for the developing larvae. Each mud cell contains one egg and is provided with several prey items. The wasp then seals the cell with a thick mud plug. After initial creation and covering of the clutch, this sphecid wasp uses more mud as a means covering and protecting the whole cluster of cells, thereby forming a smooth appearance, and a uniform nest. The entire nest may attain an area equal to, or larger than, the size of an average human fist.”
“After finishing a series of cells, she leaves and does not return. While consuming the prey and increasing in size, the larva molts several times, until it molts into a pupa. Once the pupa has developed into an adult wasp, the adult emerges from its pupal case and breaks out of its mud chamber.”
“Various parasites attack these nests, including several species of cuckoo wasps, primarily by sneaking into the nest while the resident mud dauber is out foraging.”
“Adults can be seen in mid-summer feeding on nectar at flowers, especially Queen Anne’s lace (Daucus carota), parsnips and water parsnips (Sium suave, Sium latifolium, Berula erecta). They have a low reproductive rate. Stings are rare due to their solitary and usually nonaggressive nature; however, nests are aggressively defended.“
“Like other solitary wasps, Sceliphron species are not aggressive unless threatened. They are sometimes regarded as beneficial due to their control of spider populations, though the spiders themselves may be beneficial in controlling pest insects.”
“This species is found in a wide variety of habitats, such as rock ledges, man-made structures, puddles and other water edges, cypress domes, in long leaf pines (Pinus palustris), and in turkey oaks.“
“S. caementarium is widespread in Canada, the United States, Central America and the West Indies, and has been introduced to many Pacific Islands (including Australia, Hawaii, and Japan), Peru and Europe, where it has become established in some countries of the Mediterranean Basin (Croatia, France and Corsica, Italy, Cyprus,Malta, the Canary Islands, and Madeira) and Austria, and Ukraine.“
“Sceliphron caementarium can reach a length of 24–28 mm (15⁄16–1+3⁄32 in). Their petiole is generally black and is about half the length of the entire abdomen, however the population in the desert southwest often has a yellow petiole. The thorax shows various yellow markings, while the abdomen is normally black, with yellow propodeum (typical of females). The eyes are black, the antennae are black, and the legs are yellow with black trochanters and femurs. Within the United States, it is the only species with yellow-marked legs. The wings are a tawny color.”
“In 1996, Birgenair Flight 301 crashed near Puerto Rico. The most probable cause of this Boeing 757 crash was a blockage in a pitot tube by a mud dauber’s nest.”
Around our home these mud-daubers favor hollows within our aluminum fencing.

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
The grandchildren and I hiked the 0.6 mile trail through old growth forest to visit a bog. In the 1830’s there was a village named Chicago along Gracie Road, which gives it the name we have today. The Chicago Bog is home to many carnivorous plants, including sundew, the pitcher plant, and more. The deepest depth of the bog is about 7.2 ft. The bog is along the Phillips Memorial Trail, which can be found on Gracie Road. Lime Hollow Nature Center, Cortland, New York.

A dragonfly landed on the log, in the above images, lying at my feet. This male Chalk-fronted Corporal (Ladona julia) is a skimmer dragonfly found in the northern United States and southern Canada.

Juveniles of both sexes are light reddish brown, with white shoulder stripes and a black stripe down the middle of the abdomen. As they mature, males develop a white pruinescence on the top of the thorax and at the base of the abdomen, while the rest of the abdomen turns black. Females become almost uniformly dark brown, with a dusting of gray pruinescence near the base of the abdomen; a few develop the same color pattern as the males.
Chalk-fronted corporals often perch horizontally on the ground or on floating objects in the water as you can see it doing here. They are gregarious for dragonflies and are commonly seen perching in groups. They readily approach humans to feed on the mosquitoes and biting flies that humans attract.
We noticed a large patch of buttercups growing in a sunny patch along the trail. Petals of these buttercups are highly lustrous owing to a special coloration mechanism: the petal’s upper surface is very smooth causing a mirror-like reflection. The flash aids in attracting pollinating insects and temperature regulation of the flower’s reproductive organs.

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

Mesquite is the Sonoran Desert smell carried by distant rain, omnipresent and humble, a survivor with tap root extending 190 feet down to draw on the water table.
Prosopis is the scientific name for about 40 species of leguminous trees. Present in North America since the Pliocene era, mesquite wood has been dated to 1300 BC.
I found this flowering mesquite bush in Finger Rock Canyon of the Catalina Mountains outside Tucson, Arizona.
They are thought to have evolved with megafauna in the New World. The loss of North American megafauna at the end of the Pleistocene era gave way to one theory of how the Prosopis spp. were able to survive.
One theory is that the loss of the megafauna allowed Prosopis spp. to use their fruit pods to attract other organisms to spread their seeds; then, with the introduction of livestock, they were able to spread into grasslands.
The plentiful legumes that develop from these flowers are edible when cooked. The shape and color of the seeds can be understood from this empty seed pod that happens to lie near a tarantula burrow.
Have you wondered, “What is ‘pileated’ about a Pileated Woodpecker? The Latin word Latin pileatus means capped, so the adjective refers to the red “cap” the bird wears. Pileated Woodpeckers mmainly eat insects, especially carpenter ants and wood-boring beetle larvae. They also eat fruits, nuts, and berries, including poison ivy berries. Pileated woodpeckers often chip out large and roughly rectangular holes in trees while searching out insects, especially ant colonies. They also lap up ants by reaching with their long tongues into crevices. They may forage around the sides of human homes or even cars and can be observed feeding at suet-type feeders, as you can see below.

Usually, pileated woodpeckers excavate their large nests in the cavities of dead trees. Woodpeckers make such large holes in dead trees that the holes can cause a small tree to break in half. The roost of a pileated woodpecker usually has multiple entrance holes. In April, the hole made by the male attracts a female for mating and raising their young. Once the brood is raised, the birds abandon the hole and do not use it the next year. When abandoned, these holes—made similarly by all woodpeckers—provide good homes in future years for many forest songbirds and a wide variety of other animals. Ecologically, the entire woodpecker family is important to the wellbeing of many other bird species. The pileated woodpecker also nests in boxes about 4.6 m (15 ft) off the ground. The large cavities made by pileated woodpeckers during their nesting process not only serve as a home for the birds but also play an essential role in the forest ecosystem by contributing to nutrient cycling. Woodpecker cavities can lead to increased soil nutrient levels and microbial activity, providing a nutrient-rich environment for other plants to grow.
A pileated woodpecker pair stays together on its territory all year round and is not migratory. They defend the territory in all seasons but tolerate floaters during the winter. Drumming is most common during courtship and to proclaim a territory. Hollow trees are often used to make the most resonant sound possible. The pattern is typically a fairly slow, deep rolling that lasts about three seconds.
Pileated woodpeckers have been observed to move to another site if any eggs have fallen out of the nest—a rare habit in birds. The cavity is unlined except for wood chips. Both parents incubate three to five eggs for 12 to 16 days. The average clutch size is four per nest. The young may take a month to fledge. The oldest known pileated woodpecker was 12 years and 11 months old. Predators at the nest can include American and Pacific martens, weasels, squirrels, rat snakes, and gray foxes. Free-flying adults have fewer predators but can be taken in some numbers by Cooper’s hawks, northern goshawks, red-shouldered hawks, red-tailed hawks, great horned owls, bald eagles, golden eagles and barred owls.

Bombylius major (commonly named the large bee-fly, the dark-edged bee-fly or the greater bee fly) is a parasitic bee mimic fly. Bombylius major is the most common type of fly within the Bombylius genus. The fly derives its name from its close resemblance to bumblebees and are often mistaken for them.
Bombylius major exhibits a unique flight behavior known as “yawing” and plays a role in general pollination, without preference of flower types. The fly does not bite, sting, or spread disease. However, the fly uses this mimicry of bumblebees to its own advantage, allowing close access to host solitary bee and wasp nests to deposit its eggs. After hatching, the larvae find their way into the nests to parasitically feed on the grubs.
Flight
It has been discovered that the fly is capable of a unique behavior, which was discovered with the use of a high speed camera. In this behavior, the flies are seen to rotate around a vertical axis as they fly (this action is known as “yawing”). However, it is still unknown what can cause this behavior to be triggered and what purpose it serves, but a proposed explanation includes mating habits. Here is an illustration of “Yaw” in the context of an airplane…substitute the fly body with head facing forward (to left).
The Bombylius major bee-fly is a common, generalist floral pollinator, meaning that it does not give preference to one flower over another, instead pollinating a wide variety of plant families and species. The fly uses its proboscis to carry and transfer the pollen. The species is a dominant pollinator within its community, sometimes even pollinating up to two thirds of the local flowers. In addition, Bombylius major will visit and pollinate plants that attract few other species. Some types of flowers, for example Pulmonaria officinalis, will be almost exclusively pollinated by Bombylius major, with other species contributing a negligible amount to that plants pollination. Some flower species, such as Delphinium tricorne, are even specifically adapted to the fly in terms of color, shape, and form. If given the choice, Bombylius major will have a consistency in plant choice.
Flower Attraction
Long distance floral attraction is governed by optical sense, with color being the most important factor. The flies are typically more attracted to blue and violet colors, and occasionally yellow, over orange and pink. However, short distance floral attraction is based on the fly’s olfactory sense.
Sunbathing Activity
The fly is mostly active during day hours when the weather conditions are warm and sunny. Bombylius major is attracted to sunnier places and is more likely to pollinate these areas, with a larger average of flower visits in areas of higher amounts of sunshine. The fly will hide in the trees during the night and usually dart away from a cast shadow and occasionally hide in clean washing brought in fresh from the washing line and fly out causing unsettled behavior in the discoverer.
Flower Description
Claytonia caroliniana is a flowering, woodland perennial herb. It grows from March though June and is one of the earliest spring ephemerals. The plant grows from spherical underground tubers in light humus. They sprout and bloom before the tree canopy develops. Once the area is shaded, the plants whither leaving only the tuberous roots underground.
The plant is edible, but its usability is limited due to difficulty harvesting and the small quantities each plant produces. Its tuberous roots are edible and rich in starch and can be cooked or eaten raw. The leaves can be eaten as well. The tuberous roots are eaten by eastern chipmunks and white-footed mice.
