Blue Flag Iris - Iris versicolor - Clajeux

J'ai été au chalet d'une amie durant la fin de semaine, sur une rivière près de Lac Simon. La rivière diffère beaucoups du lac où je reste d'habitude, particulièrement du côté faune et flore. La diversité d'espèces de libellule, par exemple, était absolument extraordinaire. J'ai pris beaucoups de soleil en sortant sur la rivière en kayak et je suis devenue très bronze. C'est chanceux que je ne brûle pas facilement! Ci-dessous se trouvent des photos de l'iris versicolore (autrement: clajeux), Iris versicolor. Ceci est la fleure-emblème du Québec. Pour moi, qui passe mon temps au Québec sur les lacs et les rivières, cette fleure est associée à la beauté du Québec et à ses eaux claires et vertes.

I went to a friend's cottage on a river near Lac Simon (Quebec). I found it to be a gorgeous place. One of the most wonderful things about the river, as compared with the lake where I usually conduct my explorations, as the diversity of flora and fauna. The variety of dragonfly types was particularly stunning. Above is the blue flag iris, iris versicolor, which I associate with Quebec's beautiful waters. This was a particularly fine specimen, glistening with dew and richly coloured.

Here's a blue flag iris from above. In the photograph below, the path toward the nectaries between the lower and upper portions is visible.

Iris versicolor

Indeed, if we look at the next photograph the place where the nectar is, as well as the pistil (the hard ridge curving over the top of the opening), is visible. The pollen gets spread over the surface leading down to the nectar, which would of course ensure that any pollinators seeking nectar at this flower would pick up plenty of pollen as well. A good system. I like that the dew on the petals is visible and sparkling in this shot.

 And, just because this flower is incredibly beautiful, here's a shot of it from below:

I got particularly damp and muddy taking this shot, as the blue flag iris likes to grow in marshy areas. Lying down under one (they're not very tall, either) therefore meant getting quite mucky.

I'm gathering my courage today.

Bumblebees - B. impatiens - Bourdons

So I suppose it's about time I talked about the garden a bit. This year, E and I are trying something new. Back in a post on July 5, 2012 (Pollination Station), I illustrated my method for ensuring pollination of some of the plants for which pollination is necessary for production. It involved running around with a brush, a decidedly inefficient and inelegant state of affairs. The garden I maintain is on three levels: ground level, second floor, and third floor. Pollinators are unfortunately quite rare on the third floor, presumably because bees well-laden with nectar and pollen don't have any interest in flying up two stories to look for more.

So this year we're trying something new. E is doing some bee research at a lab at the university, under the supervision of a researcher who has been invaluable in her assistance to get us started. Basically, we're raising a bumblebee colony. Bad. Ass.

... The process is surprisingly sensitive. We ran around with nets and pill bottles early in the season, capturing bumblebees (bombus impatiens), because early in the spring all the bumblebees are queens; the queen comes out of hibernation and flies around collecting pollen and nectar and looking for a suitable nest site, then eventually starts laying eggs. Actually, there's a rather low success rate for b. impatiens colonies, so it was necessary to capture multiple queens in hopes that one would reproduce, so I should say that only some of them eventually start laying eggs.

So. We caught some bees. Watched and waited. Finally, one of them appears to be incubating eggs. The rest have been released, and Gardenia (that's the name we gave the successful queen) has been moved outside and we've opened up the incubator for her in case she wants to forage. We've supplied her with nectar and pollen, as well as cotton to use in forming the initial nest, so she doesn't actually have to leave. Eventually her workers will leave the hive to forage. And then they will pollinate our garden goodies and I won't have to run around with a paintbrush anymore.

Peeking into the nest

 You'll notice right away while looking at the above shot that b. impatiens doesn't make the organized honeycomb that people generally expect when thinking of bees.

The incubator

 This is the exterior of the incubator. The closer portion is where the nest is; the further portion is where we're putting a capful of nectar for Gardenia, which prevents the need for her to venture outside in order to support the colony (the pollen we've provided her with is visible in the photo of the nest).

Location of the incubator

We've tucked the incubator into a quiet corner of the deck for now, with the exit facing directly into the planters where I've put some of the flowers I planted this year in order to supply the colony. We are anticipating the possibility that we'll have to provide them with nectar or pollen as the season wears on, but we'll be monitoring the colony closely.

We'll be moving the nest into its proper box soon so that the hive has the chance to grow and spread.

But of course, social bees aren't the only bees who pollinate the garden. Far from it; solitary bees (bees who do not form colonies, but rather forage & reproduce individually) are extremely common and also very important for pollination. Fortunately, keeping solitary bees is considerably less time-consuming and difficult than trying to establish a colony. Solitary bees just need to be provided with a suitable nest site, and they'll move right on in!

This is where my dad kicks ass. I was doing some research on solitary bees (I'm less familiar with them), and found out exactly how to set up for solitary bees. My father, once I explained the process to him, pulled out his drill bits and got some wood and helped me set up some solitary bee space.

I'm not really expecting to get any solitary bees this year (it's a little late for nesting), but at the very least we should get some next year. Since we have an apple tree in the back yard, that's to the good.

 Solitary bees are of varying sizes, so need tunnels of varying sizes to accommodate them. My dad drilled some holes of varying sizes on two sides of two of our fenceposts (total of four sides drilled). Solitary bees look for tunnels of the right size to nest in; holes in wood are appealing enough, so that's what we've put up here.

My dad then sheltered the bee houses, to keep the rain out (wetness prevents the bees from prospering).

So there we have it.  My dad rocks. So do bees.

Of course, this blog just wouldn't be what I've always envisioned it to be if I didn't take a moment to also share a photo of something I thought was particularly beautiful today. Enjoy.

Cow Vetch - Vicia Cracca

V. cracca flower stalk and fern-like leaves

This is my specimen photo of cow vetch (fr. vesce craque, pois à crapauds), vicia cracca. It is a very hardy, invasive plant, considered a weed where it isn't native. Though it isn't native to Canada, in this environment it isn't particularly problematic. Cow vetch, being a meadow flower, has limited scope in a mostly wooded area like the one where I photographed this plant. It can be problematic as an invasive plant, but it is an excellent fixer of nitrogen, so it's not entirely bad, either. The difficulty with this plant is in its tendency to spread aggressively, choking and eventually squeezing out other plants.

V.  cracca flower stalk

I love the shape of the flower; it looks a bit like a rabbit's head to me. I love the way the deeper purple veins in the upper petals are clearly visible here, in their double-loop pattern. Cow vetch is particularly attractive to bees and butterflies, so sticking around these for a while results in quite a show.

I took a stroll this morning with my father to identify two shrubs, the berries of which seem to be particularly attractive to birds; yesterday, we spotted a cedar waxwing on one of them. This area is mostly too dense and forested for cedar waxwings, so it was a nice sight. The plant that attracted it was a red elderberry (fr. sureau rouge), sambucus racemosa.

Also, my parents adopted kittens recently. They're brothers, and close to 4 months old now. Here's a picture of them spooning. Just for the cute.
