Gypsy Moths [Lymantria dispar L.], also known as the European Gypsy Moth and North American Gypsy Moth, are considered an invasive species since its larvae consume the leaves of over 500 species (according to Hamilton Conservation Authority) of both deciduous and coniferous trees, shrubs and plants.  The starving larva are transported by wind currents.  The US Forest Service calls them one of North America ’s most devastating forest pests.

Adult males are a light brown and gray colour with a darker brown mottled pattern on their wings. The male has feathery brown antennae and a wingspan of just under 2 inches.  Females are slightly larger (2.5 inches) and are almost completely white in colour having a few dark-coloured stripes across her wings.  She has a light-coloured fuzzy head.  Females have a few dark markings on their wings and are flightless. 

The moth was accidentally introduced to North America around 1868 in a failed attempt at starting a silk industry.  It first evolved in Europe and Asia . 

Reproducing one a year, females usually lay egg masses in late June through August on tree trucks, but have also been known to lay eggs on rocks, etc.  Each mass contains about 100 – 1,500 eggs.  As the female lays the eggs, she covers them with hair that she pulls from her abdomen.  Protected by the warmth of the female’s hairs, the eggs remain in their mass over the winter and hatch in the late spring or early summer. The hair mixture also provides protection from predators.

Egg masses are beige coloured and about 3-4 cm long and 1-2 cm wide.

A hatched egg mass is lighter in colour and has tiny exit holes on the surface.  The eggs will no longer be felt inside.

As they hatch from their tiny, dark-coloured eggs, the larva are about 3 mm in size, but will grow to be about 50 to 90 mm. The larvae go through several developmental stages and pupate in the late summer.  Males emerge first and begin to search for females.  After mating, both adults die.

Apparently the fuzzy hairs that protect the egg mass can cause a serious rash if touched by bare skin.  This I learned only after researching this topic.  While investigating the egg mass, I touched the hairs quite a bit, even rubbing them between my fingers and into my palm to reveal the eggs.  Perhaps since it was spring, the potency of the irritant had decreased over the winter months, but I did not experience any irritation or rash.

Did you know...   

that adult Gypsy Moths only live about a week since they do not have an active digestive system?  While they can drink moisture, they cannot eat.

Gypsy Moths cause havoc in a number of ways:

A Gypsy Moth caterpillar can eat about one square meter of foliage.  Multiply that with an infestation and entire forests can be stripped of their leaves.  Defoliation causes a tree stress and weakens it.  After about two years, the tree can no longer produce its own energy and may die.  Many mature trees can be lost in this way.

Have you ever heard of caterpillar "frass"?  With the large amount of eating that they do, caterpillars also produce a lot of fecal matter, or "poop" called "frass".  In a large infestation, frass has been known to cover backyards, outdoor furniture, etc. decreasing a homeowner's enjoyment and use of their land.

Hand picking the eggs masses, and spraying is done in an effort to rid an area of these pests.  While scraping egg masses off infested trees, removal of caterpillars and pheromone traps work to some degree, often a biological pesticide called Bacillus thuringiensis kurstaki (Btk) is sprayed over large areas.  Made of a dormant bacteria that is toxic to Gypsy Moth caterpillars, this pesticide affects only this species and, although costly since it needs to be sprayed from the air, is very effective.

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!
