Critters in my Saskatchewan Garden

I had a couple fascinating encounters with critters of the insect kind today.

I was out photographing plants when this fellow landed on my shirt. You would not believe how difficult it is to get a photograph of something that lands on your belly button! These busy prehistoric-looking helicopters of the insect world are beautiful and I hadn't been able to photograph a blue one until now! I posted pictures of a red one a few weeks ago, but that one was tiny compared to this monster. I estimate this one to be about 4 and 1/2 inches (19 cm) long. Shortly thereafter, I saw this plump critter inching past my green garden shoes. I can't quite identify it. Does anybody know what it is? There are online pictures of sphinx moth caterpillars that look similar. It lacks horns, has a brown head, and has about four diagonal white stripes on its sides. It has a more prominent diagonal white stripe that crosses over the top of the back end of the caterpillar.  Thanks to internet references, this seems to be a poplar sphinx moth caterpillar.

Oh yes, and a pretty butterfly on an Echinacea flower! This bed contains several flowers attractive to bees and butterflies: purple Liatris, Echinacea purpurea, and Mondarda didyma (Bergamot, Bee balm).

Echinacea and Bee Balm

Two well-known perennials are blooming this week. Both are big butterfly favourites and grow as wildflowers elsewhere in the world.

Pictured: A purple Mondarda didyma (Bergamot, Bee Balm). This plant does spread by rhizomes, popping up several new plants around the base, but it is not yet the worst of the garden thugs. If you have this plant, you need to either regularly hack up the growth around the base or give the new plants away to friends.

Pictured: Pink Echinacea, some melon-colored short lilies, and a background of pink Malva Moschata (Mallow).

My Echinacea is the old fashioned type whichI grew from seed. Of course, now they have the hybrids with orange and yellow flowers, double-flowered and double-decker flowers, and ones that can operate heavy machinery...
