Trembling Aspen

It was the summer of 2017, did you see it?

The Populus tremuloides (Trembling Aspen or Quaking Aspen) groves were struggling, and suffering tremendously. The defoliation caused by the Tent Caterpillar Malacosoma disstria was so severe, that combined with the severe drought, the vigour and vitality of the Aspen Trees was greatly reduced.  2017 saw the fourth year of the Tent Caterpillar infestation in Saskatoon. When healthy trees that are completely stripped of their leaves are able to refoliate their leaves after the caterpillars have feasted, however the second growth is smaller and, indeed, may be inadequate to compensate for the damage caused. The attack of the caterpillars may even kill the top of the tree, side branches and even the whole tree may expire with multi-years of excessive defoliation.

 

James J. Worrall et al, explains that drought, tent caterpillars and other factors contribute to the decline of Trembling Aspens. Severe drought precipitates the most drastic decline, followed by foliage stripped by tent caterpillars  year after year. Aspen stands cannot recover from such shocks to the system on a multiyear basis, without relief.

 

“It’s almost as if nature has forgotten how to rain in parts of Saskatchewan,[9]” said David Phillips, senior Climatologist with Environment Canada, who goes on to explain that, “It really does show you the kind of climate you have: a desert — dry, semi-arid, almost like Pheonix, Ariz. — where the days can be very hot, and in this case bone dry and not a cloud in the sky. All that heat from the day radiates into space … It left the nights relatively cool.[2]” Saskatoon received only 243.6 millimetres [9.6 inches] of precipitation, bringing 2017 into the top five driest years for the city.

Not only was 2017 setting records for the driest years in history books, the problem for the Trembling Aspen was compounded as being the worst for the Tent Caterpillar plague. “We’re in a boom period for the tent caterpillar,” [10] ” said Tyler Wist, Field crop entomologist for Agriculture and AgriFood Canada. The tent caterpillar has a natural predator in birds, as well as the eggs of the sarcophagid fly.

 Effects on overall health of aspen.  Repeated defoliation by forest tent caterpillar may not allow trees to recover to a normal state of health, which can lead to decline.  ~ Natural Resources Canada

Following two or more years of severe feeding there is a general decline in tree health, including twig and branch dieback. After three or four consecutive years of being stripped of their leaves trees can be weakened and may be more susceptible to insects, such as wood borers, and stem disease. Following forest tent caterpillar infestations the incidence of hypoxylon canker, a fungal stem disease, may increase and cause extensive damage in aspen forests.  “~ Forestry Branch

Late spring frosts kill buds leading to early, mass larval stravation. Alberta Government.

“When populations are low, the egg masses on small plants can be removed by hand and destroyed between July and the following spring. Hand picking can inflict significant larval mortality.
Destruction of occupied tents by hand or with a brush leads to colony collapse. Pruning to remove egg masses, tents, or groups of larvae must be done sparingly to avoid injuring the plant. Using fire to accomplish this is not recommended as it damages the plant more than the defoliation.”~Forest Health Protection
 The trembling aspen is known to grow as a clonal colony in which the stems [trunks] arise from one huge conjoined root system.  Whereas the tree stems of the Trembling Aspen may be determined by its tree rings, the roots may be much older than that of the tree trunks.  In the semi-arid regions of the west, Trembling Aspen are more likely to establish new trees via suckering from an established root system rather than from seed.  It is intriguing to learn that the Aspen Tree is really only a small fraction of a much larger organism.  Malcolm F. Squires reports that clones of Aspens may have sprouted following the Pleistocene era after the retreat of the great ice age, creating the oldest organisms in the world.  One can tell one Aspen clone growth from another, as leaves will emerge in the spring and turn to yellow in the fall in the same clone, and a neighbouring clone will exhibit a different time scale.
If a clone of Aspen trees from the same root is even aged, and has thrived in near to full sunlight, is severely attacked and stripped of its leaves by tent caterpillars causing some of the Aspen trees to die back.  The Aspen roots, in some cases, if the soil is healthy, be able to regenerate from suckers.  Young saplings will rise from the roots in the openings, or these young trees may take advantage of thin crowns.  The Aspen stand will show this uneven age structure, until the remaining tree trunks die off, and all the tree stems become even aged.
“Jack Schultz, a Pennsylvania State University entomologist… discovered that aspens react chemically to insect attack.  Soon after the caterpillar start chewing, the trees’ remaining leaves produce bitter-tasting phenol compounds to discourage further eating” [5]
 In 2017, it was seen that the Trembling Aspen stands lost their leaves, and a second smaller growth was seen coming late in the summer season.  Watch if and how the Aspen stand recovers in 2018.  It will be also interesting to note if 2018 again succumbs to a double whammy of drought and tent caterpillar.  Saskatchewan is a province of cyclical weather alternating between drought and years with a high water table [perhaps even flooding].   The tent caterpillars well, their cycle lasts between three to seven years, and they normally re-occur in 15-20 year intervals.
The round leaves turning golden in the autumn months, quivering, and catching the light as the breeze tosses the golden discs this way and that, give the Trembling Aspen the appearance of being a “Money Tree” as its branches dance in gold.
Silviculture is the practice of controlling the establishment, growth, composition, health, and quality of forests to meet diverse needs and values. The name comes from the Latin silvi- (forest) + culture (as in growing).  Richard St. Barbe Baker attended Cambridge University, graduating as a silviculturist.
Enroll your body, soul and spirit and engage your time to do what you know best. Dedicate yourself to the work at hand and you will be rewarded by the fruits you will bear!”― Israelmore Ayivor, The Great Hand Book of Quotes

Specialization is for insects

Happy New Year with a New Species!

Not at the top of a mountain, nor at the bottom depths of the ocean. Not in Cambodia nor in Greater Meekong.  A new species has been discovered by Daniel L. Hubert, Morgan D. Jackson, and James J. Smith of the Michigan State University and University of Guelph.  Wow!!!

“Speciation is the process by which life diversifies into discrete forms, and understanding its underlying mechanisms remains a primary focus for biologists. …The speciation mechanism he proposed described a situation where a subpopulation of a herbivore specialist species begins to oviposit (lay eggs) in a host plant species other than its own, and within a “sufficient number” of generations, the laws of inheritance reinforce this subpopulation’s fidelity for that host such that it becomes a ‘phytophagic variety’ distinct from its ancestors. ”

An absolutely beautiful little “Peacock fly” referred to as Rhagoletis Bushi is the name of the new species. The Tephritidae fly family are often referred to as “Peacock Flies” due to their colourful and intricate markings. This nick name is quite puzzling as the Greek root tephros translates as “ash grey.” Rhagoletis Bushi is not ash grey at all, but rather has a russet or ruddy head, white wings with russet banding, and striping across the thorax longitudinally from head towards abdomen. Wheras the abdomen has circular striping colors and similar markings of dangerous arthropods such as wasps which may help Rhagoletis Bushi avoid predation. Rhagoletis Bushi is a fly and does not have a stinger. Ironically the natural enemies include tiny wasps belonging to the family Diapriidae and parasitoid wasps of the Braconidae family.

God knows Himself and every created thing perfectly. Not a blade of grass or the tiniest insect escapes His eye. Mother Angelica

Rhagoletis Bushi has a unique wing banding pattern which other tabellaria species do not have.

The other identifying feature is that Rhagoletis Bushi loves the fruit of the silver buffaloberry (S. Argentea).

“A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.”
— Robert Heinlein

To locate a cute little Rhagoletis Bushi, find a patch of Silver Buffaloberry (S. Argentea) shrubs. These small trees grow 1-6 meters [3-20 feet] high, and have large thorns. The berries can be formed into cakes, smoked over a wood fire, and eaten, or added to pemmican [a combination of berry and buffalo meat]. Though the Silver Buffaloberry fruit is described as sout or bitter similar to the chokecherry [Prunus viriniana L.], it is great for pies, james, jellies and wine and have a high Vitamin C content. Edible Wild Plants: A North American Field Guide introudecs presentation of the berries, for beverage, sauce, dessert or jelly.
Besides Rhagoletis Bushi, elk, mule deer, white-tailed deer, grouse, and birds love the berries of the Silver Buffaloberry. As a matter of fact, the buffalo berry is a staple food for the Sharp-tailed grouse diet, the provincial bird of Saskatchewan.

The Silver Buffaloberry improves the habitat, and has been used for watershed management. Thickets of buffaloberry arise from root stocks which produce clones of dense bush and vegetation affording both food and cover for wildlife. Additionally Silver Buffaloberry is nitrogen fixing for the soil. Look for the Silver buffaloberry across the prairie parklands as it is a native bush, along wet meadows, marshy areas, near streams, and rivers.

Quite often in nature plants will support endangered species. Mardon skipper (Polites mardon) butterfly, and Zerene fritillaries (Speyeria zerene) are two butterflies which depend upon the Early-Blue Violet (Viola adunca) for instance. In this case, the thorny buffaloberry Shepherdia argentea supports Rhagoletis Bushi, a specialized frugivore [fruit eater], with a particular taste for this host plant. The buffaloberry fruit is about 5 to 6.35 mm in diameter or 0.2 to 0.25 inches

According to Hulbert, “the flies themselves don’t cause too much trouble for the buffaloberry especially considering they’re both native to North America and have evolved with each other over the course of millennia or more.”  In regards to the Richard St. Barbe Baker Afforestation area, he continues to say; “This fly is one (albeit small) part of the area’s richness!”

Insect Hotels keep good bugs cozy according to Susan Mulvihill. So if you are set on aiding the plight of pollinators and beneficial insects, one way is to construct an insect hotel, or create a botanical garden with native species of plants. And another is to plant Silver Buffaloberry (S. Argentea)

This autumn, when you are out walking past the Silver Buffaloberry bush, keep your eye peeled for the new species just discovered, Rhagoletis Bushi.  “In North America the genus Rhagoletis, is represented by 24 species widely distributed in temperate regions of Canada and the U.S.A. (Bush, 1966; Berlocher & Bush, 1982; Berlocher, 1984; Foote
et al., 1993).[2] “And now there are 25 species!!! Generally speaking, Tephritidae are small to medium-sized (2.5–10 mm or 0.0984-.39 inches) flies, so keep your eyes peeled; the coloration and markings of Rhagoletis Bushi will make the search quite worthwhile!

So Happy New Year, with a New Species

All the best to you and yours in 2018

Knowledge of the Butterfly

There is another aspect of life on the land; while working in forest or garden a man has time for meditation and indeed his very act is devotion. He becomes in tune with the Infinite. ~Richard St. Barbe Baker

“Entomology extends the limits of being in new directions, so that I walk in nature with a sense of greater space and freedom. It suggests, besides, that the universe is not rough-hewn, but perfect in its details. Nature will bear the closest inspection; she invites us to lay our eye level with the smallest leaf and take an insect view of its plane.”—Henry David Thoreau.

In popular esteem the butterflies among the insects are what the birds are among the higher animals—the most attractive and beautiful members of the great group to which they belong. Entomology happens to be the branch of zoology focussing on the study of insects. Butterflies are primarily day fliers (diurnal) and remarkable for the delicacy and beauty of their membranous wings, covered with myriads of tiny scales that overlap one another like the shingles on a house and show an infinite variety of hue through the coloring of the scales and their arrangement upon the translucent membrane running between the wing veins. It is this characteristic structure of the wings that gives to the great order of butterflies and moths its name “Lepidoptera”, meaning scale-winged.

The Entomological Society of Saskatchewan takes part in the North American Butterfly Count July 21. The society members will also give talks, presentations and displays.

Take the time to learn how to establish a pollinator native plant ribbon or butterfly garden. The North American Butterfly Association will provide Certification for your butterfly garden.

Ronald R. Hooper states that 160 species of butterflies are known in Saskatchewan, in families known as skippers, swallowtails, whites, sulphurs, marbles, hairstreaks, harvester, metalmarks, brushfooted butterflies, meadow browns, and coppers (see bibliography for scientific nomenclature). Every fall the Monarchs journey from Canada to California or Mexico, and they return to Canada in the spring. During this migration phone Nature Saskatchewan’s toll-free line at 1-800-667-HOOT (4668) to report any Monarch Butterfly sightings.  When you are out and about this season, keep an ear out, do tell if there is the slightest murmuration when the butterflies migrate past.

And, whereas, the Monarch is known to migrate, this is not the case with all butterflies. Most of the Swallowtails pass the winter as chrysalids while practically all the Angle-wings pass the winter as adults. The Graylings and the Fritillaries are typical examples of butterflies which hibernate as newly hatched larvae. Many species simply find such shelter as they may at or near the soil surface, others may hibernate under boards, stones, or tufts of grass. The Swallowtails, nearly all of which hibernate in the chrysalis stage. Other examples are the various Whites, the Orange-tips, and isolated species like the Wanderer, and the Spring Azure and the American Copper. Now, an adult butterfly seems a fragile creature to endure the long cold months of winter, however many of our most beautiful species habitually hibernate as adults, finding shelter in such situations as hollow trees, the crevices in rocks, the openings beneath loose bark or even the outer bark on the under side of a large branch.

The butterflies furnish the best known examples of insect transformations. The change from the egg to the caterpillar or larva, from the caterpillar to the pupa or chrysalis, and from the chrysalis to the butterfly or imago is doubtless the most generally known fact concerning the life histories of insects. If you do not know the name of the lepidoptera larva, butterfly or moth that you have found, try to take a photograph of it. Identify your sighting at this web site which features an image gallery. If you have a photo of a caterpillar send in information about the plant that the caterpillar was found upon to Butterflies and Moths of North America and help to grow the database.

The Entomological Society of Canada hosts a Common Names database for insects and other related arthropods.

“What hand would crush the silken-wingèd fly,
The youngest of inconstant April’s minions,
Because it cannot climb the purest sky,
Where the swan sings,

Not thine.”
Percy Bysshe Shelley.

There is another aspect of life on the land; while working in forest or garden a man has time for meditation and indeed his very act is devotion. He becomes in tune with the Infinite.
