• Monarch: # 4 of “23 Butterflies in 2023”

    Leonard Weber

    February 3, 2023

    Monarch, probably the best known of all North American buterflues, is common in Eliza Howell Park. It is present from mid/late May until late September

    On Purple Coneflower in July

    A nectaring butterfly, it is attracted to a variety of flowers, providing good views of it, both when the wings are closed and when the wings are open.

    On New England Aster in September

    The Monarch is famous for its annual long-distance migration. The above butterfly, looking like a newly emerged adult on September 11 last year, was about to leave on its long, long flight to Mexico for the winter.

    The individuals that leave here in the Fall do not return in the Spring. It is the next generation, having never been here before, that arrives in May.

    On Red Clover in June

    Monarch is also well known for its relationship to milkweed plants. It lays its eggs only on different species of milkweed; the caterpillars eat only milkweed leaves; and the chemicals derived from the plants make both the caterpillars and adult butterflies very distasteful to birds, an important protection.

    Three different species of milkweed grow in Eliza Howell Park: Common Milkweed, Swamp Milkweed, and Butterfly Weed.

    The Monarch is quite large, with a wingspan of about 4 inches. Its size, its bright colors, its numbers, its 4-month-plus presence, its attraction to many different flowers all make it a butterfly easy to find on visits to the park.

    Perhaps because Monarchs are so often talked about, there can be a tendency for someone learning about butterflies to identify other orange and black butterflies as Monarchs. The next butterfly in this series is a different species that looks very much like a Monarch.

  • Red-spotted Purple: #3 of “23 Butterflies of 2023”

    Leonard Weber

    January 30, 2023

    The third butterfly in this series of 23 butterflies likely to be seen in Eliza Howell Park in 2023 is the Red-spotted Purple.

    It is not the most common butterfly here, but it is present every year. It is not the most predictable in terms of when it shows up, but that only enhances my excitement when I see it.

    Called “purple,” it has lovely blue and black coloring.

    On Wild Bergamot

    It is equally attractive with the wings closed, showing the spots.

    Same individual as above

    It has a wingspan of about 3 inches and is often found at the edges of forests. It sometimes seeks out flowers for nectar (where I watch it), but it is a butterfly that has other tastes as well. It will visit damp soil, sap, rotting fruit, and dung, and is often seen on the ground.

    There is a chance of seeing a Red-spotted Purple in the park any time during the months of June, July, and August, though mid-July to early August may be best.

    Southern Michigan is at the northern end of its normal range. (Light green on the map means “uncommon”)

    Kaufman Field Guide to Butterflies of North America

    After years of enjoying sightings of the Red-spotted Purple, I have decided that it is equally lovely with wings closed as with wings open. That is not the case with most butterflies.

    The next two photos are of the same individual.

    On Purple Coneflower

    The Red-spotted Purple spends the winter in the caterpillar stage, in a rolled leaf in one of the host trees it uses — such as cottonwood, cherry, or willow.

    A butterfly’s life isn’t easy and even lovely butterflies sometimes get faded and torn. The next photo is of a Red-spotted Purple from the middle of August last year.

    In some years, I see the first Red-spotted Purple in June. In some years, it is in July. It is always a very welcome sight!

  • After the Snowfall: Images from a Walk in the Park

    Leonard Weber

    January 26, 2023

    The snowfall in Detroit on January 25 was heavy in both senses: 1) it added up to several inches, and 2) it was a wet snow, weighty on a shovel and sticking to surfaces.

    Here are some images from my next-day nature walk in Eliza Howell Park.

  • Silver-spotted Skipper: #2 of “23 Butterflies in 2023”

    Leonard Weber

    January 22, 2023

    The species selected for the second in this series on butterflies of Eliza Howell Park is the Silver-spotted Skipper. It is quite common in the park, frequently seen here from the middle of June to the middle of August.

    On Wild Bergamot

    The Silver-spotted Skipper is large for a skipper, the largest skipper in our area, with a wingspan of about 2 inches. There are over 200 different skippers in North America, many of which are similar in appearance and very difficult to tell apart. The Silver-spotted is different, quite easy to identify because of the orange and white (silver?) patches.

    It frequents flowers for nectar.

    On Red Clover

    It seems to be attracted to flowers at the edge of the forest, which is where the best wildflower field is located in the park. I often see it nectaring on Wild Bergamot flowers, which are plentiful in this flower field in late June and in July.

    Silver-spotted Skipper is active over a large part of the country, more common in the East.

    Kaufman Field Guide to Butterflies of North America

    Though frequently seen nectaring, it is also sometimes found perching on grasses and leaves.

    The Silver-spotted Skipper spends the winter as a caterpillar, with the chrysalis stage in the spring. The earliest I have seen an adult is mid-May, with June being the usual time.

    A favorite August photo is this one.

    On Queen Anne’s Lace

    There are many attractive butterflies found in Eliza Howell Park, as this series will show. This is one that a visitor has an excellent chance of seeing on any day (on any non-rainy day after mid-morning) during their season.

  • American Lady: # 1 of “23 Butterflies in 2023”

    Leonard Weber

    January 16, 2023

    Since Eliza Howell Park in Detroit is slowly getting recognized as a great place to see butterflies, this might be a good year to highlight some of the butterflies that can be found here, presenting them one species at a time. 

    It’s a long time until butterfly season in Michigan, but an early start is needed to include 23 species this year.

    First in this series is American Lady.

    On Wild Bergamot

    American Lady is a medium-sized butterfly, with a wingspan of about 2 inches. It is present among the blooming flowers from mid-May through July, feeding on nectar. It is not exactly common, but it is definitely not rare. In Eliza Howell, I see them most frequently in July.

    American Lady is striking, both with wings open and wings closed. The underwings, with the two eyespots and a pattern similar to a spider web, always catch my attention.

    On Red Clover
    On Purple Coneflower

    American Lady is found in much of the United States. It is unable to survive as an adult in the winter in the northern parts of its range. At least part of the early-season northern population results from a northward spring migration from southern states.

    Kaufman Field Guide to Butterflies
    of North America

    American Ladies are attracted to a variety of flowers in the park; the three included here are among their favorites. In July, there is a good chance of getting a good look at an American Lady by standing quietly by a patch of Purple Coneflowers.

    On Purple Coneflower

    Earlier in the season, before the coneflowers bloom, Red Clover is a favorite.

    On Red Clover

    American Lady is neither rare nor well known. It is a great find, however, fascinating to watch. If someone has never met an American Lady, this might be the year to find the opportunity to see one.

    ……….

    The “23 Butterflies in 2023” series is not intended to include all the species sometimes found in the park.There are probably another 20 species that can be seen occasionally. It is, however, intended to highlight those most likely to be noticed by park visitors seeking butterflies.

    All photos included in the series are from Eliza Howell Park and, unless otherwise indicated, were taken by the author.

  • Colorful Winter Mushrooms

    Leonard Weber

    January 10, 2023

    They are small and, at this time of the year, they lead to pleasant stops on nature walks in Eliza Howell Park. They are mushrooms, found on dead wood, that just started fruiting or remained fresh-looking as December ended and January began.

    One of these is called Crowded Parchment.

    This fallen oak branch is slender, but it was bright enough to be seen from a distance on December 29. It invited close-up views.

    Many fallen logs and branches that retain their bark are home to multicolored shelf fungi from the Fall into the Winter. These can be found over a number of weeks..

    These sorts of mushrooms are usually referred to Turkey Tail (because of the flat, fan-shaped, multicolored appearance), even though some might be Fals Turkey Tail or possibly even something else.

    One mushroom that is truly a Winter mushroom (more of them may still appear later this month) is often found low on a standing dead tree or stump. It is known as Velvet Foot.

    (I thank Kathleen Garrett for calling my attention to these, photographed on January 10.)

    There was point in time, not too many years ago, when I thought that the last of the colorful mushrooms each year were to be seen in the Fall. I know now that this is definitely not the reality.

  • Birds of Eliza Howell Park: Another Year Begins

    Leonard Weber

    January 3, 2023

    At the beginning of a new year, I often review some of the records of my Eliza Howell Park observations. Recently, I have been checking the records of bird sightings.

    January 2023 is the beginning of Bird Record Year 19. In 2022, I saw 117 different species, typical of the number I have been seeing each year.

    Photo by Margaret Weber

    One of the January regulars is the Northern Cardinal (a female is shown here). Cardinals are among the twenty plus species that are found year-round in the park, usually recorded every month of every year.

    Other year-round Eliza Howell residents include Red-tailed Hawk and Downy Woodpecker.

    The year-round birds are joined in the Winter by a very limited number of species of northern birds that spend their Winters here, southern Michigan being south for them.

    The American Tree Sparrow is one of these, in good numbers so far this month, foraging for seeds in the wildflower fields.

    Photo by Margaret Weber

    The Winter months of December, January, and February have, as expected, the lowest number of species each year, usually fewer than 30 per month.

    Things begin to change in March, when the earliest-arriving Summer residents begin to show up. The Killdeer is always one of these March arrivals.

    Photo by Margaret Weber

    Another early-returning Summer resident is the Wood Duck.

    Photo by Margaret Weber

    The number of species seen in a month jumps dramatically in April and peaks in May, as more Summer residents return and the species that breed north of here and winter to the south pass through.

    The combination of Summer residents and migrating species makes it possible to see as many as 90 different species in the park in May, an exciting month for bird watching.

    Among the many species that return every Spring and nest in Eliza Howell are the Rose-breasted Grosbeak,

    the Barn Swallow,

    the Great-crested Flycatcher,

    and the Baltimore Oriole.

    The species migrating through are also numerous, but because they pause only briefly in the park, some of them may not be seen every year.

    A significant percentage of the migrants each Spring and Fall are warblers (represented here by a Nashville Warbler) …

    Photo by Margaret Weber

    … and sparrows (such as the White-throated Sparrow).

    Photo by Margaret Weber

    The Scarlet Tanager is a Summer resident in this part of the country, but it does not breed in Eliza Howell, so my sightings of it are brief ones when it arrives back in Michigan on its way to its breeding location.

    Photo by Margaret Weber

    The resident birds are engaged in raising their young in the Summer.

    September and October are again migration months, as the birds head back south. Most years, the second highest monthly total of species, after May, is September.

    One of my favorite late season migrants is the White-crowned Sparrow.

    Photo by Margaret Weber

    As Fall transitions to Winter, I am frequently greeted by a loud Blue Jay upon my arrival at the park.

    Photo by Margaret Weber

    Perhaps this very quick review of the Eliza Howell bird year provides some minimal sense of the park’s avian riches. It certainly puts me in the mood to get out frequently to see what this year brings!

  • Twelve Buds at Christmas: Trees in Pause Mode

    Leonard Weber

    December 20, 2022

    During Christmas season walks in Eliza Howell Park, I often stop under leaf-bare deciduous trees and check the tips of branches. I am admiring the growth buds and appreciating the reassurance that the trees, though currently in pause, have a head start on Spring.

    As with leaves and bark and fruit, buds vary with species. I recently collected photos of twelve varieties.

    Red Maple
    Eastern Cottonwood
    American Beech
    Basswood
    Norway Maple
    Aspen
    Yellow-bud Hickory
    Shagbark Hickory
    Hawthorn
    Red Oak
    Sycamore
    Sugar Maple

    The buds have grown this much before going dormant. Now they are waiting for the temperature and the sap to rise.

    When observing tree buds in Winter, I am reminded that it is natural in this climate to be less active in winter. But… If I pause too much, I fear I will miss out on some of nature’s wonders, which continue throughout the Winter.

  • Marvelous Moss: On Logs in the Vernal Pool

    Leonard Weber

    December 15, 2022

    There is something about moss-covered logs that I find very attractive. Late Fall, before snow covers the ground (and the logs) in Eliza Howell Park, is the time I often go looking for them.

    What I find especially fascinating is the contrast between the way the moss appears when I look down at the log from standing height…

    … and the way it looks close-up and somewhat magnified.

    There are thousands of different species of moss and I go from log to log to sample the differences.

    In the major wooded area of Eliza Howell Park, there is a sizable vernal pool, not visible from the path. It typically dries up in late Summer and begins to refill with Winter precipitation. This wet and shady environment, with many fallen trees and tree limbs, is a great place for moss to flourish. It is now accessible.

    Mosses are plants, seedless spore-bearing plants that have stems and leaves but no true roots. They help to decompose the logs and recycle the nutrients.

    The pool is replenished by the Winter snows and Spring rains and has surface water for perhaps 8 months, providing a home and breeding area for a variety of animals, especially invertebrates. (The next photo is from April, as the leaves were just starting to grow on the trees in the background.)

    As I walk the park on these gray days of December, I feequently take a detour to the vernal pool and take advantage of this opportunity to get close to the fascinating mosses.

  • Fruit of Horse Nettle: Attractive, Seldom Eaten

    Leonard Weber

    December 11, 2022

    Horse Nettle is one of the few perennials in Eliza Howell Park that hold their fruit into Winter. The berries, which remind me of small yellow tomatoes, are still on the plants well into December.

    Horse Nettle (also known as Carolina Horsenettle and a variety of other names) is a native species. It is not truly a nettle; rather, it is in the nightshade family. All parts of the plant are poisonous to some degree, the mature fruit probably the most so.

    Horse Nettle grows 2 to 3 feet tall, often in small patches. Now that most of the the leaves have falken, the fruit clusters are easily visible. Each berry is about 1/2 inch in  diameter

    Horse Nettle is a field plant that both attracts and repels. The flowers and the fruit, both developing and mature, are quite  attractive…

    …but all parts of the plant are poisonous, at least to mammals. And the plant has sharp spines (perhaps the reason for being called “nettle”) that discourage browsing by livestock and other plant-eating mammals.

    Reports indicate that some birds, like Ring-necked Pheasants and Wild Turkeys, eat the fruit, but I have not yet seen any evidence that animals consume the berries here. The more common fruit-eating birds (such as Robins and Cedar Waxwings and Starlings) have shown no interest.

    Plants often promote the next generation by spreading seeds, using a variety of  dispersal methods. The seeds of fruit-producing plants often get scattered by being eaten by animals and deposited elsewhere in scat.

    Horse Nettle fruit is seedy,…

    …but its poisonous nature discourages consumption of it. This species spreads primarily by underground rhizomes and by dropped fruit/seeds. So it is not a surprize that it is usually found in patches.

    I am often asked whether a particular fruit is edible. The answer for Horse Nettle is clear: it is NOT. 

    The poisonous nature of the fruit directs attention to the fascinating methods plants have developed to produce future generations.
