March 2018

March started off with lots of snow. It is too bad we didn’t have snow like this in January for our snow- shoeing activity. March is also the Spring (or Vernal) Equinox (on Tuesday, March 20 this year). The days are starting to get longer and the Equinox marks the date when the length of the day equals the length of the night (and the sun’s energy is equal in both north and south of the equator). The changing day length all has to do with the tilt of the Earth as it orbits around the sun. Our orbit, however, in not circular. It is shaped like an oval, or what scientists call an elliptical orbit.   In March our elliptical path will take us out to the far ends of the oval. We are actually moving away from the sun. But the tilt of the Earth makes up for it by exposing the northern part of the planet to more direct energy from the sun. In other words, it’s going to get warmer.

Spring is arriving!

It is very easy for our government to monitor how much electricity we use from hour to hour on each and every day. We can use this technology to show our government we care about climate change.

The World Wildlife Fund-Canada (WWF) calls on people across the country to join others around the world to send a strong global message and show your commitment to the planet. You can switch on your social power by simply switching off your lights. You can learn more and sign up at

The 12th annual Earth Hour takes place at 8:30 p.m. local time on Saturday, March 24, 2018.

Six continents, over 170 countries, and 24 time zones will be united as a global community, making our voices heard through individual action. Turn off as much power as you can and focus on your commitment to climate action for the rest of this year.

Butterflies when there is snow?

The arrival of spring, marked by the Spring (or Vernal) Equinox, will mean temperatures will start to warm and our snow will start to melt. One of the most fascinating things I find about the warmer temperatures is the waking of our hibernating butterflies. In Saskatchewan we have several types

of butterflies that hibernate over the winter months as adults. Mourning Cloaks, anglewings, and tortoiseshells are the only Saskatchewan butterflies that hibernate as adults. (Other butterflies and moths usually survive the winter in the egg stage, although some will overwinter in the, caterpillar or pupae/ chrysalis stages). The amazing part is they freeze completely solid in the winter and come back to life when they thaw out. Watch the daily temperatures in March. If we get a day that is 12 degrees or warmer be sure to keep your eyes open for brown-coloured butterflies fluttering about. These brown butterflies are the Mourning Cloaks or Nymphalis antiopa.

You would think that a butterfly with a name like Mourning Cloak would be somewhat depressing; but it is hard to get depressed on the first warm, sunny day after a long, cold winter! These large, dark butterflies (with light upperwing edges) pop onto the scene on the first warm sunny day when the temperature hits 12 degrees or warmer. They will often appear on a very warm day in March even when there is still snow on the ground. Don’t worry; they go back into hibernation until the willows bloom in April. Mourning Cloaks have a long life span for a butterfly. The adult life span is about 10 months to a year (most adult butterflies in only live a week or so). The adult Mourning Cloak will usually come out of hibernation in April and lives until June. In early April, willow catkins are about the only flower available, so look for Mourning Cloaks around the ‘pussy willows’.

They will also feed on sap and mud (for moisture and minerals). The males are also anxious to find a mate at this time of year, so you will often see the males chasing after every female that visits a willow tree. The spiky caterpillars of Mourning Cloaks hatch in June. They feed in groups, spinning webs around

the twigs and leaves of host tree (usually a willow or poplar). Sometimes they can be considered a pest when large groups of caterpillars feed on our local elm trees. The group feeding is actually to scare predators. If you get close to a group of feeding Mourning Cloak caterpillars, they will shake in unison, giving the appearance of a larger animal.

These guys are all about avoiding predators. It is thought that the light border on the adult wing resembles a worm or caterpillar, and helps lure attacks from predators away from the butterfly’s fat, furry body. The adults emerge from metamorphosis in July, but they don’t seem to like the really hot days of summer. August is usually spent in aestivation (a state of dormancy similar to hibernation). The under- wings of the Mourning Cloak resemble dead leaves, so they can be well camouflaged during their aestivation period. Once the weather cools in the fall, the Mourning Cloaks once again make an appearance.           During the fall they feed voraciously on flower nectar, decaying fruit, and sap. A good place to look for Mourning Cloaks is around tree trunks that have been drilled by the Yellow-bellied Sapsucker. They overwinter as unmated adults and the cycle begins once again on the first warm days of spring.
