Anne Elliott's photos with the keyword: Canada Thistle

This photo of several tiny (size: 22-26 mm) Skipper butterflies on a Creeping/Canada Thistle was taken on 23 July 2015, at Darryl Teskey's property. These unusual butterflies have such large eyes : ) "The eyes of Skippers are different from those of other butterflies. They have a space between the cones and rods which allows light from each ommatidium to spill into neighbouring rods, effectively increasing their resolution and sensitivity. As a result Skippers can fly very accurately from one spot to another. This different type of eye structure is one of the reasons why taxonomists place them in a different super-family to all other butterflies - the Hesperioidea." Source: www.learnaboutbutterflies.com/Anatomy.htm "The European Skipper can be found on the wing in June and July. Becoming an invasive species of butterfly, it can be found in the grasslands of central Alberta spreading about 25 km every year. The European Skipper can be recognized by its bright orange wings marked by dark wing veins. The edge of the wings are bordered with black. The aptly named European Skipper is also known as the Essex Skipper in its native habitat. The mature adults prefer grassland flowers and the caterpillars the grass itself. The European Skipper did not arrive in Alberta until 1987 slowly migrating from eastern provinces or from laying their eggs in transported hay bales." Source: Acorn, John. Butterflies of Alberta.

On this day, five of us spent the day botanizing the land belonging to Darryl Teskey, SW of Calgary and W of Millarville (maybe a 40-minute drive from Calgary). This was the first time I had been there and I'm so glad I was invited to go - I would have missed all sorts of things, including a family of Ruffed Grouse and several fungi. These Grouse were the rare rufous-morph, and we startled them when we were walking through the forest in their direction. Usually, you don't see Grouse because they are so well-hidden. When you get fairly close (sometimes very close) to them, they suddenly "explode" from the tangle of shrubs and plants of the forest floor, making ones heart beat fast! We were taken by surprise when we came across a nearby statue of Saint Francis of Assisi, who is known as the patron saint of animals and the environment. A nice idea, I thought. Our walk took us over grassland and through forest, many places treacherous with so many fallen logs which were often barely visible. I have never, ever seen so many tiny Skipper butterflies - there must have been hundreds or even thousands of these bright orange beauties that were flying or perched on flowers of every colour. Fortunately, the rain stayed away until we started driving back to Calgary. Quite a lot of black clouds, reminding me of the tornado that passed through Calgary just the day before (22 July 2015). Our purpose, as always, was to find and list everything that we saw - wildflowers, trees, grasses, birds, insects, fungi, etc.. Our leader then compiles an extensive list of our finds and this is later sent to the landowner, along with any photos that we might take. Always a win/win situation, as the landowner then has a much better idea of just what is on his property, and we have a most enjoyable day.

On 2 August 2014, I went on a birding trip with friends to Bow Valley Provincial Park, west of Calgary, at the very foot of the eastern edge of the Rocky Mountains. Takes around 45 minutes to drive there from the western edge of Calgary. This was the park that I finally made myself drive to on 20 July, with my youngest daughter. It's a good thing that my daughter and I didn't come across certain certain things that were seen on 2 August! Not sure if the insect in my macro image is a moth or butterfly - I think a moth, though the antennae don't appear to be very wide. I'm going to use the trip leader's write-up of the events of the day - thank you, Andrew, for yet another great trip to a very beautiful place. Each year, this trip to the park makes such a great day. Hope you don't mind my using your report here! I should add that all these birds were far, far away, too far for photos and, for me with no binoculars, too far to see either properly or at all. We walked about 6 km in total. "We had six participants on this trip. We arrived at BVPP with early morning temperatures which started to warm up. We walked around the Flowing Waters Trail where we heard many of the species we recorded. The highlight of this segment was a Blue Headed Vireo (conceivably a Cassin's but we decided Blue Headed was the higher probability, based on location and the song). I do have some photographs but doubt they would delineate between the two species. (Later: confirmed to be a Cassin's). We had lunch in the Whitefish area and then went over to the Many Springs Trail. As we were assembling in the small Many Springs Trail's car parking area, we looked back along the road we just driven in by and saw a fairly large very glossy, very black Black Bear amble across the road and vanish into the woods. We carried on walking around the trail. About half way around we heard a call from ahead which sounded something like "bear on the trail". We exchanged a few shouted communications with the group ahead of us and concluded that there was a black bear with two cubs wandering around on the trail about 200m ahead of us. We all looked at the (suddenly small looking) bear spray I had with me and decided to turn around and head back to the car park. There were still six of us when we got back. We stopped briefly at Middle Lake and then stopped at the Morleyville Church on Hwy 1A on the way back to Calgary. We had cell coverage all day so I recorded all of the sightings on the Birdlog app, which created the convenient summary of the trip which follows.

Most people call this Canada Thistle, but Creeping Thistle is the more accurate name, as this is an introduced plant from Europe. Was lucky to catch a plant with a flower still on it, as most of the ones I see have gone to seed now. This is an invasive plant that has taken over vast areas all over the city, preventing our wonderful native wildflowers from growing. Has become a real problem that needs to be dealt with - somehow!

Taken at the Ann & Sandy Cross Conservation Area, SW of Calgary, on August 19th. Unfortunately, Creeping Thistle (also called Canada Thistle) is intensely invasive. Status in Alberta is Noxious.

So beautiful, yet so devastating! This is one of our main invasive weeds, also called Canada Thistle, and it has taken over so many parts of our lovely natural areas. This species is native throughout Europe and northern Asia, and widely introduced elsewhere (including here, unfortunately). The name "Canada Thistle, is misleading, as the plant is not native to this country. Creeping Thistle is the preferred name - and WE don't want to be blamed for something so destructive, when we didn't start the whole thing, lol!! Each spring, it forms extensive clonal colonies from an underground root system that sends up numerous erect stems. Photographed (macro) this particular plant at Clearwater Park, on the west side of the city, off Highway 8, September 4th last year. en.wikipedia.org/wiki/Cirsium_arvense

This is where we spent the day botanizing on Saturday, 21st August - Horshoe Canyon, near Drumheller, in the Badlands of Alberta. To the north east of our city, there are endless miles of flat prairie. Then, suddenly, one comes across the amazing Badlands - our own mini Grand Canyon! This is one of the best-known sites in the Canadian Badlands, located 17 kilometres west of Drumheller on Highway 9. Horseshoe Canyon is about 145 km (88 miles) from Calgary. It takes between 1½ hours and 2 hours to drive there from Calgary. This shot was taken just before I reached the top rim after a day of plant search. Unfortunately, the invasive Creeping/Canada Thistle was growing here in abundance. "Horseshoe Canyon is an isolated pocket of badlands amidst the Alberta prairie. Apart from its aesthetic value, Horseshoe Canyon also represents three unique habitats or ecosystems: the prairie, the wooded coulee slopes and the badlands." www.natureconservancy.ca/site/PageServer?pagename=ab_ncc_... www.tyrrellmuseum.com/

A macro of a small Canada Thistle flower, Cirsium arvense, (also known locally as Creeping Thistle). This species was introduced from France. Also called Field Thistle. The stems of this noxious weed (with beautiful flowers) creep underground, forming colonies and it seems to have invaded everywhere, preventing our native species from growing. Photographed this one at Horseshoe Canyon, near Drumheller, in the Alberta Badlands. talkaboutwildlife.ca/profile/?s=1281

Not the greatest photo when it comes to an ID, but I rather liked the backlit view of this Fritillary butterfly. Seen on 29th August, when we hiked and botanized the Fullerton Loop trail, starting from Allan Bill Pond on Highway 66, Kananaskis.

I like the spotted eye of this Cabbage White butterfly! These butterflies always lead me on a chase, but this time, I was eventually lucky. Saw it sitting on this Canada/Creeping Thistle in North Glenmore Park.

This small Green Stink Bug was wandering all over a Canada Thistle this afternoon. I love seeing these. Actually, I saw all sorts of things on my walk today, starting off with a family of Ring-necked Pheasants running through the long grass. Also saw what must have been bear droppings - filled with berries!

A very blurry photo, but I have never caught one before with its wings (shields) wide open.

This plant originated in Eurasia and was introduced all across Canada. Though it is a valuable nectar source for honey bees, it has become a troublesome and noxious weed in Alberta.

Not sure what kind of Skipper this is, but it looks different from others I have photographed.

This is an attractive weed!

This plant originated in Eurasia but unfortunately was introduced all across Canada. It should not really be called Canada Thistle seeing as it is an introduced species, but rather, Creeping Thistle. It has become a problem noxious weed in Alberta.
