Pseudoscorpions

From time to time I noticed this small spider -- so I thought -- in the basement. I payed no attention to it for the longest time thinking that it was merely a crab spider. After taking these pictures and further examination, it became evident that crab spiders do not have these pincers. So now what? After considerable searching under different names I found from the bugguide.net that it is a pseudoscorpion. It is common in North America right up to the treeline.

It gets around by hitchhiking on larger flying insects, and is very beneficial to humans, preying on tiny insects like aphids, ants etc. Though it does produce venom, its pincers are too small to inflict injury to humans and are thus considered harmless. 

A Sparrow's Nest in the Grass

One of the parents perched on a tree near their nest in the tall grass.

In a field near our house we could frequently see a pair of song sparrows [Melospiza melodia] perch on this small tree and then hover down into the tall grass. One obviously suspects a nest would be near by. I carefully moved the brush aside ensuring not to affect the vegitation thus possibly exposing the nest and sure enought found this nest very well hidden deep below the underbrush.

These little babies look like they are ready to leave the nest at anytime now.

The Everwelcome Dragonfly

 This dragonfly is one of our most common at this time of year. According to KAUFMAN Field Guide to Insects  of North America, ISBN-13/EAN: 978-0-618-15310-7 or ISBN-10: 0-618-15310-1   Page 48 this is the Dot-tailed Whiteface [Leucorrhinia intacta]. In the evenings when the mosquitoes come out in swarms, these Whitefaces are welcome critters since the make quick work of the mosquitoes.

The Brilliant Six Spotted Tiger Beetle

While working on a pile of rocks I would from time to time enjoy the company of these beautiful metallic green insects as they swiftly scurry about. According to Bugs of Ontario, it is a Six Spotted Tiger Beetle.

This spring I have seen numerous such beetles as well as the tiny red spiders. Wherever I happen to be working in the ground I come across at least one. This implies that there is an abundance of these little predators. Both the tiger beetle and the tiny red spiders prey on insect pests like ants or caterpillars for the tiger beetle and aphids for the spiders. 

This property was abandoned around 1968 and largely reforested around 1971. We moved here 10 years ago and have never used any insecticides on the property so one could say that it is very free insect friendly. I wonder if that is why there is such an abundance of these unusual bugs. Never would have dreamed of seeing them in the suburbs of Bells Corners, where we used to live and we might have seen an ant or mosquito.

White-throated Sparrow

Unfortunatey we do get the occasional bird that will collide with our windows. Although it is most frequent in the bigger windows they also tend to collide with the smaller ones. This morning early this very pretty white-throated sparrow [Zonotrichia albicollis] was stunned by such an incident but luckily came to and flew away.

A Visit of a Small Hawk in our Yard

Bird feeder was very quiet last Thursday morning. Didn't make any mind of it until looking out the back window I saw this little hawk. It looks smaller than a rock pigeon. Definitely smaller than a Crow.  While it was perched at sunrise it would periodically and rapidly flick its tail back and forth like an inverted windshield wiper as seen at this distant perch. It was as if it was waking up. At the time there was very little other activity in the yard.  I know that it was too large to be a kestrel or sparrow hawk. 

Its size made me think that it was a merlin of the falcon family but it didn't have the characteristic side burns. I have at least seven different bird guides thankfully and each describes the same bird in slightly different ways which is often very helpful. I relied on my initial three bird guides by Sibley, Audubon and the Royal Ontario Museum and none were really of much help since they did not give enough information to distinguish the characteristics of this bird. By the odd colouring I thought that it might be a Juvenile cooper's, or sharp-shinned. The colours say maybe a northern goshawk but it is very small for a goshawk.

At this point I hadn't found nor bothered to find the other bird guides, and proceeded to post the following two pictures 

on Facebook to see if any friends could identify them. Before the day was up a friend forwarded these picture to his avid birder friend and by the end of the day came back with a molting Sharp-Shinned Hawk [Accipiter Striatus].

I later found another bird guide by Kaufman that much more clearly confirmed this identification as a juvenile Sharp-shinned. It showed a very good semblance of the white spotted back of this bird and I have scanned the page out of the book for the reader's benefit. It is from Field Guide to Birds of North America by Kenn Kaufman, 2000, Houghton Mifflin Company, ISBN 0-618-13219-8.   I think this pretty much confirms the identification although the colours of the breast feathers were softer and never showed the sharper and more distinct brown and white pattern.

My Introduction to Prickley Ash

A bane of the woodlot owner is Prickly Ash [Zanthoxylum americanum]. It is a very thorny bush and though I had heard of it I had never identified it in the wild until last summer when I made a visit to a friend's woodlot near Kingston ON. It is an awful thorny bush and likely worse than a wild rose. It is undoubtedly impossible to walk through without chaps or other leg protection. 

I was of the false opinion that this was probably not an issue in our area until, on a recent trip this summer in the Perth area I had noticed an unusual bush that stood about 2 metres high and had interesting clusters of berries near the stem. I took a sample of it home for positive identification. Sure enough using Trees in Canada ISBN 1-55041-199-3, it was definitely identified as Prickly ash. I have since found it along a road not more than 6 km away from here, and more recently found a patch of it in our very own woodlot. 

Unlike buckthorn and other invasive plants, Prickly Ash is apparently not that hard to control by just cutting it back. Buckthorn on the other hand just keeps sprouting up even after three or four years of cutting back.

Deer Damage to Little Maples

After a month of nice seasonal wintery weather, over the last week all the snow has basically melted away with the rain. I took advantage of this lowered ground cover to see if I could now find the sugar maples that we planted in the front field last spring. During the summer and fall the herbaceous growth was so thick that I was unable to find any of the maples that we planted. Now with the snow having pushed down the weeds, the saplings were very easy to find with their blue flagging tape around the stems. Had we not marked each tree with blue flagging tape finding them would have been totally hopeless.

Deciduous trees do not complete well against grasses in the first stages of life, until they reach above the height of the mature weeds. In our field the trees have to compete against plants like golden rod, purple loosestife, barn grass and joe pye weed all of which typically grow up to a metre (3 feet) tall. When neighbours throw out old carpeting I often offer to pick them up and use them for weed control around seedlings in grassy areas.

I will cut the carpeting into 60 cm (2 feet) squares and cut a slit from the center out. I will also cut a small 3 inch cross at the centre to make some room to position it around the stem. I then place the carpet piece around the base of the small tree fuzzy side down. This quite effectively stops the weeds from growing right next to the tree and from competing with it for moisture, light and nutrients. Seems to work quite well. Since the carpets take some time to decompose, they can usually be reused to at least start one more tree.

Out of the 10 sugar maples that we planted only two which were quite short did not have their tops chomped off by deer. This is a problem since the terminal bud (at the top of the tree) is what really promotes tree growth. It is not uncommon to find young maples bushy and stunted because of deer browsing. I will have to come up with some sort of a protective mechanism for the terminal bud. The attached website provides some excellent information on controlling deer damage.

A Meal for One Bird is the Life of Another

Today there was evidence of a real life drama in the snow as witnessed in these photos. The feathers appeared to be the same hue as that of a slate-colored junco of which there is a quite a few that feed on the cracked corn that we broadcast over the snow. We have noticed a sharp shinned or cooper's hawk visiting our fields from time to time which might identify the predator in this drama who is only trying to sustain itself.  Other than the feathers there was no waste.

Planting of a Honey Locust

Since I live inside the City of Ottawa I am entitled to one free tree each year as part of the city's Tree Program.  This year I requested and received a Honey Locust. That is to say that the tag on the tree states Locust Gleditsia. In my tree book the Honey Locust's scientific name is Gleditsia triacanthos L. Another name for it is the Thorny locust and indeed it is thorny.  It produces long bean-like seed pods.

The delivered tree's height is 2.4 m. ~8 feet. and dbh (diameter of the stem at breast height which is 1.3 m (~4¼ feet) above ground) is 1.6 cm (5/8 in).

Its French name is févier épineux.

The tree is planted in the acre around the house.

Workshop on Fomes Annosa (Heterobasidion annosum)

Yesterday, Sept 21, 2010, I attended a workshop on Fomes Annosa (Heterobasidion annosum) (FA) which was put on by Richard Wilson Phd. a tree pathologist with the Ontario Ministry of Natural Resources based out of Sault Ste Marie. It was held at the Larose Forest which is located about 50 kilometres East of Ottawa.

FA is a fungus that attacks particularly red pine (Pr) trees and only affects injured trees since it gets in through the wound.

The morning consisted of technical presentations including an Overview of Forest Health in Ontario, Fomes Root Rot in Ontario, and Overview of the Pesticides Act and Regulations: What You need to know in order to apply pesticides. The first two presentations were provided by Dr. Wilson while the pesticide presentation was given by Scott Olan, Pesticide Specialist with the Ontario Ministry of the Environment.

In the afternoon we proceeded out to the forest to observe signs and symptoms of Fomes Annosa, discussion on Red Pine management, and various management methods and options.

Heartwood includes a number of small red pine (Pr) groves. FA effects mainly the Pr and what makes it so unique is that Pr roots will graft together with roots of neighbouring Pr trees and share nutrients.

What I learned from this workshop was how trees are exposed to the FA and methods to identify the disease and to minimize its spread. A Pr becomes particularly susceptible when it is cut down. The stump then becomes a scar where the fungus can take hold and it then can travel to the neighbouring trees through the grafted root system killing the neighbouring trees. 

One of the interesting methods of controlling this spread it to dig a trench around an affected area thus effectively cutting off the root connections with neighbouring trees. This technique was used in the Larose Forest long ago and it proved to be quite effective since healthy neighbouring trees outside such a trench survived well. We looked at three such trenches which looked like meteor craters or imitations of Stonehenge.

Stung by a Wasp

We have our nephew from Nova Scotia visiting us here in Eastern Ontario. He has been hired to do renovations and other jobs. One of his jobs is to cut the grass which he completed yesterday. Just as he was finishing this job he was stung several times by a wasp. It is a type of ground wasp and very small, about 10 mm long, as pictured here. His reaction to the stings was quite remarkably minimal, like a mosquito bite. He did apply "Afterbite" immediately which must have helped.

The Ever Beautiful Flowers of the Highbush Cranberry

As with all other plants the highbush cranberry (Viburnum trilobum) bloomed very early this year. These can be found throughout the woodlot and seem to have propagated quite naturally since they are randomly located. This is yet another white spring flower. An interesting note is that the ring of white petals are infertile flowers designed to attract insects onto less attractive fertile flowers in the centre.

Virgina Waterleaf under the Butternut Tree

The butternut tree nearest our house has a very interesting ground cover plant growing in its shade. After much searching I have been able to identify it as Virginia Waterleaf (Hydrophyllum virginianum). Like the Canada anemone it propagates by rhizomes and well as seed and is just as easily transplanted. It looks like another candidate for our natural landscaping plans. This is a picture of the ground-cover with an inset of the flower as seen under the butternut tree. This is a another white flower with a very slight purplish tinge.

Canada Anemone

It seems like it is time for the white flowers to all come out at the same time. Pictured here is the Canada Anemone (Anemone canadensis) a wild flower which grows on the road allowance adjacent and south east of Heartwood. It creates a nice ground cover and is apparently easy to transplant by moving a part of the rhizomatous root system. I might seriously consider making it part of the future landscaping plan around our house. The internet does warn however that it can be invasive  once allowed to flourish.

Tree planting Today

The Tree Planting Party

Picked up bare-root stock from the Ferguson Forest Centre in Kemptville. With the help of my daughter and grandson, we planted an interesting variety, including 10 each of nannyberry, sugar maple, scots pine, jack pine, birch, honey locust, and red cedar, as well as the 20 canker resistant butternuts supplied as part of the butternut recovery Program. The objective was to introduce more biodiversity to the tree stands. It was a great afternoon, with nice weather and a light breeze. 

Small Yellow Moth

During the summer months there is a frequent bright yellow visitor that flutters around in our front yard going from flower to flower. While moving our furniture to accommodate our Christmas Tree we found the remains of the moth that is pictured here. I never realized how difficult it can be to identify moths since there appears to be so many species and subspecies. Many are similar and yet not exactly the same. The closest moth that I was able to identify in this case was the False Crocus Geometer [Xanthotype urticaria]. The colour is similar however the shape of the wing looks more like a Pale Beauty [Campaea perlata] which is definitely a different colour being mainly white . Also the False Crocus Geometer has a more mottled yellow colour than this sample. So using my resources at hand this is as close as I have been able to come to identifying the moth. I think the next time I get a chance to shop for field identification books I might consider a book just on moths and butterflies.

Firefly Larvae are alive and doing well in Eastern Ontario

Last night I went to the garden to pull some fresh carrots and spotted the bio luminescent glow of this insect which until now, I always thought was a glowworm. I first found this insect here in 2004 and each fall thereafter. One fall they were so abundant and literally everywhere even throughout the forest. They were spread out no more than a metre (3 feet) apart.

I first thought that this was a glowworm but I bought a new book on Insects titled Kaufman Field Guide to Insects of North America ISBN-10:0-618-15310-1 and it clearly identifies this glowing insect as the larva of a firefly[Genus Photuris for sure and probably photuris pennsylvanica.] This makes total sense because we experience many fireflies in our fields in the evenings and all summer long it seems. The typical glowworm on the other hand has a real worm-like appearance. It is typically long and cylindrical and not at all like this insect.

Firefly larvae prey on snails which is a good thing. We have no shortage of them either.

Giant Water Bug

Arriving home this afternoon I noticed on the driveway near the back steps a Giant Water Bug [Lethocerus americanus]. It probably flew in since it ended up on its back - turned turtle - and was attempting to turn itself over while flailing away.

By the time I got back out it had righted itself and found itself a small puddle to rest in. This is the state that it was in when I took these photos. 20 minutes later he was gone and must have flown away. About 10 years ago we found the same bug on our drivway in the suburbs where we lived, in the west end of Ottawa. At that time we were much less well prepared, or interested, to identify it without the bug books I have now and the quality of internet resources.

This beetle will attack and prey on small fish, frogs and snakes as well as other bugs, and it will bite a person if irritated.

Burying Beetle

Yesterday I found a dead grey squirrel by the roadside. It was close to the roadway so I decided to move it into the ditch expecting in due course for a turkey vulture or crow to find it and clean it up. So I grabbed a stick and flung the carcass into the ditch and it uncovered a pair of unusual beetles. I didn't have a camera so couldn't take their pictures for better identification, and I am not inclined to kill them so was not able to identify them better that two black beetles with 4 orange spots. My Bugs of Ontario book identifies them as a species of Nicrophorus or burying beetles with interesting behaviours. Unusual for a beetle they actually pair up and take care of their young. Typically when they find a smaller carcass such as a mouse they will bury to hide it from competitors. This squirrel carcass was obviously far too big for these two 15 mm sized beetles and the roadside shoulder gravel was likely too hard to bury in.
