An Eastern Tiger Swallowtail butterfly with severe wing damage sipping nectar from a fresh Canadian Thistle flower head. Wing damage due to activity around sharp spiny thistles will likely lead to an early end for this butterfly's season.

 

Considered common and more abundant, this year.

A little breeze only and this kind of nature-art is gone.

A very small Fritillary. They like open sunny meadows. It was fun photographing this one. All I had to do was kneel in the midst of a Canada Thistle patch and wait for it to come and go as it flew from one plant to another. It gave me some great chances of ventral and dorsal views.

Looking back through old photos, I was startled to find this one from five years ago.

 

The native plants in the foreground have been grazed by animals and overtaken by Canada thistle.

 

The roots of the trees along the bank on the right have been exposed by over use of human visitors. The eroded topsoil is backing up in the water and has created the perfect condition for an overabundance of cattails.

 

Because soil cannot be brought in from elsewhere, or relocated from within this state natural area, this spring a group of us stewards will be closing off this location by fence and planting native grasses in an effort to slow down any sediment coming down the canyon walls in hopes of restoring what's been damaged.

Larinus planus is a species of true weevil. It is used as an agent of biological pest control against the noxious weed Canada thistle (Cirsium arvense).

The adult weevil is dark brown or black with light colored mottled hairs on its body. It is about 7-8 millimeters long.

This weevil is native to Central and Eastern Europe. It was first accidentally introduced to the United States in the 1960s. The first published record is from Maryland in 1971. Postel, Belgium (wollige distelsnuitkever)

This thistle have been attacked by the Canada thistle gall fly.

The gall is home for the new flies.

I only learned the name of this plant the other day. Taken at my favorite wildflower ditch at Elk Island, it is the only plant of this type that I came across this summer. I had taken a mental note of it's location after spotting it for the first time, and later could not find it, doubting my memory I searched many other locations and did not find it again for sometime, and basically at the location I figured it was to start with. It was like searching for a needle in a haystack.

 

I was very happy to find it again. I have taken a number of images of it on a number of occasions and will present a few to you over the next few days.

 

I have a number of files to rename as previously I simply called them Jumbo Thistle or Super Thistle. It does actually go by a number of common names I have found such as Spear Thistle, Bull Thistle and Scottish Thistle. I love thistle plants and this one just seemed like a common Canadian Thistle on steroids.

This female monarch is feeding here on a Canada thistle flower. I hope she finds a few milkweed plants around to lay her eggs on as the monarch population here in North America is still in free fall and should be protected under the Endangered Species Act.

American Snout butterfly taking nectar from a Canadian Thistle floret.

 

A knowledgeable friend says this is the first Am Snout he has seen on a Thistle in over 35 seasons of almost daily area butterfly outings. Considered rare this far north. A migrant from the southern states where it can be quite common. Winters are too harsh for it to survive here.

While the flower is beautiful the plant is invasive and extremely hard to eradicate, they will reproduce by seed or by root buds. Cattle generally will not graze near them; they can take over a field in just a few years if left uncontrolled.

Feisty Broad-winged Skipper butterfly enjoying fresh Canadian Thistle nectar.

 

Limited to bog and marsh settings. Appearing early this year, as it usually emerges in late July. Considered somewhat rare, but can be locally abundant.

Canadian Thistle is a serious weed, but the goldfinch just love them.

A Canadian thistle stands ready to burst open and spread its seeds that are carried by the wind. This is a noxious weed that Government officials are trying to eradicate. It can take over native plants and kill off plants that are beneficial for the environment.

"And this'll do for this visit!"

Shooting in my favorite ditch for wildflowers today at Elk Island Nat. Park, pickings are getting slim as most everything is turning to seed including most of the Canada Thistle.Although this is a crop of the original file, my intensions when shooting were for this area, as I liked the way the flower and the ant werebacked by the yellow flower in the background. I did the best I could to align them when shooting.

 

Although I find thistles a very attractive plant when in flower, I do find it tough to compose, as usually there are several blooms all clumped together . this one was by itself, and is likely what caught my eye to bein with. I only noticed the ant when I was composing so I thought of it as a bonus. Whwn processing I noticed the tiny spider, so I consider that an extra bonus.

Another new species, this weevil is a fresh one, it loses that yellow colouring as it ages.
