I photographed both species of mining bee on the same plant at the same time of day. Spring is my favourite time of year.  Not only because of the returning birds and the start of the nesting season, but also because it is a great time to find insects.  Winters in Canada are generally devoid of insect life, and the warmer temperatures and blooming flowers bring with them a great increase in arthropod activity. As we were exploring the upper section of Mission Creek Park in Kelowna, I found a sunny spot with a current bush loaded with a variety of insects.  Most of them were either the black one (left) or the tawny one (right), both members of the genus Andrena .  I wrote a blog recently on the tawny mining bee, which you can see here .  The fact that there were so many and that they were active mid-April is not surprising given their nature. I photographed both with my D500 Nikon camera and 500 mm PF telephoto lens.  I also used a 1.4x teleconverter, t...

Predatory stink bug (left) vs herbivorous stink bug (right) "Ewww!  It's a stink bug." You may have heard that, or even uttered it.  But not all stink bugs are bad.  Besides omitting a foul odour, they have a reputation for being pests.  This is especially true for the brown marmorated stink bug (see my blog on it here ), an invasive species that can lay waste to vegetation.  Some, like the rough stink bug shown above on the left, are predators of other insects, usually the harmful ones. Another thing you can do to verify your suspicions is to examine the beak of the stink bug and compare it to its antennae.  Now, I wouldn't blame you if such a task gives you the willies and was to be avoided at all costs, but someone with a keen sense of adventure or the ability to hold a bug could do it.  The beak of an herbivorous stink bug is as narrow or narrower than its antennae, while predatory stink bugs have a beak at least twice as thick as their antennae....

I photographed this Milbert's tortiseshell near the H2O center in Kelowna. At first, I thought it was a painted lady.  However, the colouring was not right, although similar.  This is the first Milbert's tortiseshell butterfly I have seen.  I did not get a very good photo of it;  It landed only for a moment and was gone again before I could get into a better position.  If you look closely, you can see that the image has been doctored.  I have the original image below; I erased the right wing and replaced it with a copy of the left one. You can see how my original image was edited to create the top image. The host plant for the caterpillars is stinging nettles.  I have always been impressed by the pain that one of these plants can impose on one who passes by a little too closely.  The pain is caused by formic acid, the same nasty chemical found in some stinging/biting ants.  The milbert's tortiseshell larvae have several defences against the t...

The yellow arrowleaf balsamroot flowers will peak next week.  Now is the time to see them. I have written on the arrowleaf balsamroot plant before ( click here ).  Also known as Okanagan sunflowers, these plants have just started to bloom.  One of the best views of them that I have found so far is from atop Dilworth Mountain at the park just above the local golf course.  They dot the plateau but are especially picturesque at the far end, away from the parking lot. I am going back again next week.  The bulk of them should be on full display.  I shot the pictures with my Z7ii Nikon camera, but I will bring a tripod with me.  I used hyperfocal focusing to get everything in focus, which worked most of the time.  Some of my images are a little soft for near-distance objects though, so I will also have to use manual focusing. The neat thing about manual focusing with a mirrorless camera is that you get a blue shimmering halo around everything that is in...

Road construction by Munson Pond.  Some of the birds I photographed there yesterday. They said they were going to build a road along the right-of-way last year and, sure enough, they were hard at it yesterday when I visited Munson Pond.  The good news is that they are over 100 feet away from the pond's edge - not a tremendous distance, but certainly not adjacent.  And, from what I could see, the wildlife continues to exist and thrive regardless of the presence of the machines. I suppose part of the reason for that is the fact that the whole area is surrounded by urbanization.  Vehicles in the surrounding area are nothing new.  Then there is the fact that they are a modest distance away.  I noticed that a black fabric barricade was put up (you can see it in front of the machines) along the whole distance.  That serves the purpose of preventing runoff and debris from heading towards the pond and prevents ground-dwelling organisms from straying too far in...

Black oil blister beetle eating spring whitlow grass.  Kelowna, early April. Our daughter was visiting us, and it seemed like a good idea to walk along the trails in the upper section of Mission Creek Park in Kelowna.  It was a banner day, both for enjoying the outdoors and finding insects that emerge early in the spring.  I photographed a half dozen of these 6-legged invertebrates, and the oddest of the bunch was the black oil blister beetle. It was hard to miss; the beetle's enormous abdomen was comical in proportion to the rest of its body.  Our youngest thought it must be a gravid queen ant.  I thought about picking it up, but there was a good chance it may have contained  Cantharidin, that nasty chemical that blister beetles possess.  I have caught a good many beetles in my time, and my beetle senses (similar to spider senses, but less fun) proved me right.  It was, in fact, a blister beetle. Part of the reason for my daughter's pronouncement...
