WASPS MORE THAN ANNOYING INSECTS

 

WASPS – MORE THAN ANNOYING STINGERS

When most people think of wasps, they visualize annoying insects that can leave you with  painful stings.

 You may be surprised to learn that wasps are remarkable pollinators, in late summer and early autumn.


Here’s their story. 

There are actually four different kinds of wasp: paper wasps, yellow jackets, hornets, and solitary wasps.

Most likely the wasps you tried to escape from at your picnic on the weekend spent their whole summer collecting caterpillars from your veggie garden.

It turns out wasps are not pests, but pest controllers.

Without wasps we would need to use way more pesticides to get rid of hungry caterpillars devouring our veggies.

Female wasps are the workhorses of the wasp colony.

During the summer female wasps have one major job along with many others.

The females’ job is to feed their baby larvae siblings who number in the thousands and have not yet pupated.

So the female wasps go in search of protein in the form of caterpillars and flies.

She feeds the chewed up caterpillars to the larvae and in return they secrete a

 carbohydrate-rich sugary solution -a food source for the females.

To make sure the food she collects is only for the sibling larvae, certain female wasps

 have been known to stuff a male wasp inside a nest cell to keep them from consuming the food brought back for the larvae.

The colony may grow up to around 10, 000 larvae and after two weeks the larvae will change into adult wasps.

You may wonder about the difference between males and females.

While the female is crazy busy gathering food for the ten of thousands of larvae, the

 male has one job and that is to fertilize the queen so she can keep producing female workers to keep the nest humming.

In the males’ defence, when needed they will help protect the nest when the female

 is busy foraging for food for the larvae.


At the end of the summer when all the siblings have turned into adult wasps, the

 female worker wasps are no longer getting a sugary drink.

So now they actively start to look elsewhere for a source of food.

They will look for something sweet at every opportunity such as overflowing garbage cans and your sweet drinks at a barbecue.

It turns out, they also search out sweet nectar from flowers.

Lucky for us, since many our pollinators are declining at an alarming rate, wasps pollinate flowers as effectively as some bees.

Knowing that, I now have a new found respect and great appreciation for wasps!

I will no longer reach for a fly swatter when wasps fly around me when enjoying a drink of pineapple juice on my patio.

I will stay calm, take a deep breath, and walk away.

As well, in early summer when I see wasps swarming around my veggies, I will now

 wish for them to stay as long as possible and gather as many caterpillars as possible.

If you want to keep wasps away from your patio apparently they hate a citrus smell so

 cut up oranges, lemons ,as well as, citronella oil will help deter them.

DON'T TREAT MOTHER EARTH LIKE A GIGANTIC GARBAGE BIN

 DON'T  TREAT MOTHER EARTH LIKE A GIGANTIC GARBAGE BIN On Sunday, October 15, the Barrie Garden Club ventured out on a dark, dreary, and drizzly day to pick up litter, along Highway 26 close to Wilson Avenue. As I was picking up all kinds of litter such as license plates, chairs, discarded clothing, plastic bags, lots  of cigarette butts, and a myriad of discarded coffee containers, I began to reflect on all the problems triggered by litter. Here in Canada, we are very lucky to have an organized system where most municipalities and cities  make sure that there are regular pick-ups for your garbage, compost, and recyclables. So it boggles my mind why so many Canadians do not use the readily provided containers, but instead  treat Mother Earth like a gigantic garbage bin. I simply cannot understand when someone buys a cup of coffee, they then go for a long hike, they  manage to carry the cup full of coffee, but the minute it’s empty, they simply cannot manage to carry  it back home a

What do you think? Can birds help combat the catastrophic impacts of climate chaos?

  What do you think? Can birds help combat the catastrophic impacts of  climate chaos ? YES! YES! A THOUSAND TIMES YES! Birds do an incredible job of  helping to create new forests by eating tons of tree seeds.  As they fly all over the forests the tree seeds in their poop is dropped on the forest  floor.  And, the poop helps to fertilize the tree seeds as they sprout into saplings. 92% of woody plants are grown from the seeds dropped by birds in their poop !  182 species are edible. 85 species are used for timber.  153 species are medicinal  plants. 156 species are ornamental.  A new study   published  in Forest Ecosystems   (20220 concluded large fruit-eating animals, including birds like toucans significantly help regenerate forests which are  giant traps for carbon, collectively, absorbing  as much as 30 percent of the world’s CO2 emissions , and store more than 1,600 gigatonnes of carbon in their soil.  In the tropics, tall, hardwood species with dense,
