Sawflies are part of the insect order Hymenoptera which also includes bees, wasps and ants.  There are about 10,000 species of Sawfly worldwide - about 600 in Canada. 

Sawflies, I'm told, don't have much of an identify of their own.  As adults, they resemble flies or wasps.  Immature, they look like caterpillars.  They differ from bees, wasps and ants in not having a "waist" and in their wing venation.

Sawflies have four wings, not the single pair characteristic of the order Diptera.

One way of identifying the larvae of the Sawfly is to closely examine the "caterpillars".  When they are disturbed, does your specimen raise its abdomen and tail into an s-shape?  If yes, you are probably looking at Sawfly larvae.

Sawflies, you'll be glad to know, don't sting.  Their name comes from the female's ovipositor.  What looks like a stinger is really a saw blade that allows the female to cut into the stems of plants to deposit her eggs.

Since adults do not eat, it is the larvae that causes all the damage to plants.

Are You Baffled 
by Bugs ?

Did you know...

That all insects are bugs, but not all bugs are insects!

 


"I dreamed
 I was a butterfly,
 flitting around 
in the sky; 
then I awoke.  
Now I wonder:  
Am I a man 
who dreamt 
of being a butterfly, 
or am I a butterfly
dreaming 
that I am a man?"

~ Chuang Tse ~
Chinese philosopher

 

Insects have 3 body parts:  a head, thorax and abdomen.  They also have six legs and two antennae.

Spiders and Scorpions have eight legs and are not considered insects!

 

According to some sources, the total number of insect species is somewhere between 15 and 30 million!

There are 900,000 known species in the world.

 

Insane About Insects ?

 

Did you know...

Scorpions can live for more than one year without eating!

 

Mosquitoes have 47 teeth, but only the female mosquitoe bites using it's proboscis.

Fireflies, sometimes called Lightningbugs, are not true bugs or flies.  They are beetles!

Every year, insects eat about one third of the world's food crops.

Only male crickets can chirp.  They will chirp faster in warm weather.  

Most insects hatch from eggs.

The average bed contains 2-6 million dust mites!

 

Are You An Enthusiastic
Entomologist ?

Did you know...

Every year, the average person eats several insects while sleeping.  

Insects breath through a complicated network of air tubes called tracheae that open along the sides of the insects body.

Nearly all insect growth involves metamorphosis.

The average housefly lives only two weeks!

A female ladybug lays about 1000 eggs in her lifetime.

Honeybees fly at a speed of 13-15 mph.

Even though spiders have eight eyes, they still can't see very well.

A cockroach can live up to 9 days without its head!
