Giant house spider.

Although it doesn't compare to some of the whoppers found in tropical climates, the giant house spider can still install a serious case of the willies to anyone sensitive to members of the arachnid family. Not only are they big, for a domestic spider in Canada, but they are fast. At almost three inches across and traveling at speeds near 2 km/hr, these hairy-bodied predators hide indoors during the day and come out at night to hunt.

It is not uncommon to discover one when lifting or moving some sedentary object. They build funnel-shaped webs to hide in. You have probably seen them; I have them in the dark corners of my garage. Their presence is verified by the large number of discarded corpses lying around its home. I found such a scene yesterday as I was cleaning around my freezer in the garage; the remains of dozens of sowbugs laid strewn about the lair evidence of its activity.

The female tends to stay within her webbed domicile while the male often leaves his home to explore; food and feminine companionship his motivations. Mating season is in the early fall. A male will discover his counterpart through wandering and, when it is time, enter her domain to mate. She can last several months after copulation is successful. He may mate with her several times and will eventually die of natural causes. She consumes the remains, his final contribution. Forty to sixty eggs are laid that hatch in the spring. About 2 percent of the young mature to adulthood where the cycle is repeated.

Although large and fast, these spiders are harmless to humans. It is very unlikely that one will bite you, even when holding one. Their fangs, albeit large, are relatively weak and are unlikely to penetrate skin. The venom causes grief only to those that are allergic to it. The reality is that these are beneficial due to their pest eating habits. Health-wise, they are not a threat to people or pets (unless your pet has got six legs). It is our fear of their large, hairy-bodied, fleet-footed forms that cause the greatest grief. Think of them as a benevolent, flightless grasshopper with an extra pair of legs. And jaws, huge jaws. (Sorry, that probably didn't help).

I found a black widow spider in a plant pot today

Image
The spider I found is a western black widow spider, one of three species of black widow that occur in North America.  The fact that this one has another red patch on the back of its abdomen above the spinnerettes tells us that it is an immature individual. The one thing that people know about black widow spiders is that they are extremely poisonous.  Their venom is something like 15x more toxic than that of a rattlesnake.  The saving grace is that there is very little venom injected from a black widow bite than what a rattlesnake can deliver.   The good news is that black widow bites seldom lead to death.  You are more likely to suffer nausea, muscle pain, and swelling around the bite.  Symptoms usually last only 12 hours or so.  Death may be a result in people with compromised immune systems or in the very young or the elderly.   In 2018, it was reported that there were 1015 cases of people bitten by black widows.  Of those, there ...

The passing of a generation

Image
Kathryn's mom and dad with our children, Josh and Leanne. A generation, for North America, tends to be between 20 and 30 years.  During that time a couple will give birth and raise children to see them repeat the pattern as they themselves have done.  Each generation has its own set of standards, values, and ideals based upon their experiences and culture, and some of that is passed down to their offspring.  What changes are the life experiences of the following generation and the new customs and ideals that are blended together as a couple becomes a family. Kathryn's mom passed away a few days ago, she was predeceased by her husband several years ago.  Both of them were the grandparents of my children, the mother and father of my wife, Kathryn.  It was my pleasure to know them and to love them as my own, for to me they were Mom and Dad.  And they were there to welcome my children into the world just as my children were with them in spirit when they left it...

Hang in there, things will get better.

The Svendsen Family - Eric, Samuel, Leanne, Joshua (top row), Nora, Kathryn, Chanelle, Emma If I could go back, in my mind, to a day in my life when I was really down, it would be nice to be able to see into the future.  If could see things as they are today, with the many blessings that have been given to me, it would give me hope knowing that things wouldn't always be so discouraging.   The message here is we do not know what the future holds.  When things are bad, it is hard to raise your head out of the mire to see beyond the darkness.  There are no guarantees, of course, that things will be better, but I think it is true that fortunes ebb and flow as tides do.  The trick is to see beyond the low points and not be too haughty during the high ones.  I know that, at this moment, things are very good.  What the future holds is unknown, but low and high points are likely in the forecast.   This is why taking satisfaction from the moment ...
