Dogday Harvestfly on Wood

The Dogday Harvestfly (Tibicen canicularis) is a type of cicada. This one was found in my friend's backyard here in Barrie. Including its wings, it was about 1 1/2 inches in length (about 40 mm).

These creatures cannot sting or bite. It is believed that the dogday harvestfly doesn't even eat. They live underground as wingless nymphs for two to five years.There, they feed on root juices until they are ready to become adults. When ready, they emerge from the dark underground, climb the nearest plant and molt their skin. Once they have climbed out of their skin and their wings have dried, they make their way to the treetops to look for a mate.

You can hear the male cicadas singing in the summer ~ this is how they find their mates!Their call sounds like a circular saw cutting through wood.

I love it when I'm able to photograph these amazing creatures.... they are hard to find (eventhough I hear them all the time).

If you would ever like to find a cicada, the best way to do so is to look on the trunks of trees during the summer. If you are lucky, you might be able to find their empty skin shells (called exuvia). If you this, just look up the tree and see if the freshly emerged cicada is still there. I was lucky enough last year to find four emerging cicadas on a tree as Bass Lake, Ontario. What a thrill that was to watch and photograph!

You can check out my Emerging Cicada post from July 22, 2012 to see pictures of cicada nymphs transforming into adults. Very cool!
