Rose weevil on a wild rose at Dutch Lake.

The rose weevil - a curious insect.
Chances are you have walked past them and never noticed them.  Even though they are a deep burgundy red and really stick out on the familiar wild rose so prevalent in Western Canada, you have to be looking for them to find them.  The rose weevil is ubiquitous throughout North America although it may be broken down into several subspecies over that range.  Rose weevils are aptly named; they feed exclusively on roses and have been known to achieve pest status with rose loving gardeners.  They happily will eat flower, pollen, buds, and rosehips, causing considerable damage when they are in great numbers.

Weevils are a type of beetle.  They are somewhat unique in that they have a long snout with a mouth at the end and antennae attached somewhere in the middle of it.  Rose weevils belong to another subgroup of weevils called leaf rolling weevils.  Many of the species in this group will lay eggs in a rolled-up leaf where the young can grow with some degree of protection.  The rose weevil does not follow in that trend though; they chew a small hole in a rosehip, remove the seeds, and lay their eggs inside.  After hatching the young enjoy the safety of the seed pod and feed on the juices supplied by the rose.

I have a macro system that I use which has worked well for me.  I use a 24 megapixel APS-C sensor camera set on manual exposure mode.  There is a 36 mm automatic extension tube then a 105 mm macro lens attached to the camera.  I use a dedicated macro lighting system that is wirelessly connected to the camera attached on the end of the lens.  Altogether it is a rather imposing package, but it generally produces excellent results.  This particular photo was taken using an ISO of 200, a shutter speed of 1/250th of a second, at an aperture of f/45.

There are a myriad of techniques and equipment you can use to achieve satisfactory macro images.  If you are interested, I have written a book on the subject.  For more information on that, click here.

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 ...
