I spotted this guy on a web on the railing of the 42nd street bridge as I was walking home. It was quite large - its body was about the size of a dime and its legs would have hung over the sides of a twonie. I think it's a Cat-faced Orbweaver.

Photos of the Week
I opened the shed to get my bike and noticed two moths on the door. One immediately crawled away to a dark inaccessible corner, but the other posed in the open long enough for me to get my camera out. I think it's a Copper Underwing. You can see where the name comes from in this iNaturalist photo.
We're past the peak of the flowers but there are still some around. I like the details of the lilies.
There was no wind for a change this morning so the reflections were very clear. Hard to even tell this is a reflection until you notice the water lilies floating in the "air".
Approaching slowly while it scolded me, this red squirrel let me get quite close before scampering up the tree. Squirrels seem to be getting more common in Saskatoon. I'd assume that was global warming, but there are lots of squirrels further north.
There are lots of these funnel weaver grass spiders around this time of the year. Usually if you approach too quickly they retreat into their funnel. But as I took photos of this one, it started coming further out - a strangely aggressive spider. But on my way home I spotted it again and waved my hand to see if it would come out again. This time it retreated as they usually do. Thinking about it, I wonder if it was seeing its reflection in the camera lens and thinking it was another spider, had come out to chase it away.
The jackrabbits are also unpredictable. Sometimes they run away as soon as they see you. Other times (or other jackrabbits) they let you get quite close. This one was keeping an eye on me, but it was busy eating fallen apples and let me get quite close.
The bumblebees like the globe thistles. And with lots of little flowers, they kept this Tricolored Bumblebee busy long enough to get some video. It seemed to be collecting nectar and not pollen.

More Ambush Bugs
I wasn’t really happy with my recent photos of the Jagged Ambush Bugs. They weren’t bad considering how small they are, the camera I was using, and that I was hand holding in the field. But a couple of days later I spotted them again, on the same thistles, and I decided I’d take a few home and see if I could do better. I used a ziplock bag from my lunch and hoped the three bugs wouldn’t kill and eat each other before I got home.
They made it home intact and I transferred them to plastic food containers, separate ones, just in case. I didn’t have any idea how/what to feed them but I hoped they’d survive overnight. (Bugs are pretty tough.)
Saturday morning I put the macro lens on the EM1 and got out my Peak Designs tripod. I started with them in a white Corel bowl. Most bugs can’t climb the slippery sides but these guys had no problems. Luckily they didn’t move too fast and I could catch them and move them back into position. (Shelley had given me strict instructions not to let them loose in the house.)
I tried focus stacking first, but they kept moving on me and there wasn’t enough light to use a fast shutter speed. Despite that, this shot came out fairly well. It's nice to get a clear look at those front claws.
I switched to using the tiny flash that came with the EM1. That gave enough light to use a small aperture to get a decent depth of field. And one of the benefits of electronic flash is that it’s so fast it helps freeze any movement.
As much as it was convenient to shoot indoors, it wasn’t a very natural setting so I decided to try outdoors. We don’t have any thistles like I found them on, so I made do with a random flower, although I have no idea if an Ambush bug would choose this kind of flower. When I put it on the flower it got dusted with pollen (sticky stuff). I had a hard time getting a decent angle since the bug was busy crawling around, but I got a few decent shots.
Showing Shelley some of the photos she mentioned how hard it was to judge size from the photos. The bugs look huge in the closeups but they're about the size of a ladybug (but flatter). So I figured I’d get a photo of it with a dime for scale. Except it refused to sit still. So I put it in the fridge for a while hoping to slow it down. (Most bugs are more lethargic when cold.) Shelley shook her head when she found a bug in the fridge, but luckily she’s a good sport about my eccentric hobbies. It didn’t help much. Either it wasn’t bothered by the cold, or it warmed up too quickly. Eventually I managed a few shots with queen Elizabeth.
I decided I had enough hundreds of photos of Ambush bugs and let them go in the garden. When I went to wash out the food containers I noticed some specks in the bottom of one. My first thought was that it was bug droppings, but they were stuck to the bottom and didn’t look quite like that. (Based on my not very extensive experience of bug droppings.) I still had the camera set up on the tripod so I took a few shots and zoomed in on the computer. Interestingly, they were clearly eggs rather than droppings. One of my bugs obviously must have been a female. I have the eggs on my dresser. I wonder how long they'll take to hatch. Given the size of the eggs, the babies are going to be very tiny!

Rusty Tussock Moth
I was walking across Innovation Place headed for Starbucks (since the coffee shop here is still closed due to Covid). As usual, I was scanning for whatever I might see, and I noticed this pair of fancy caterpillars. According to Seek, they're Rusty Tussock Moth caterpillars.
The one above was quite a bit smaller, which might means it's male. The larger one below is perhaps a female.
As with just about any creature you investigate, Rusty Tussock Moths have some interesting details. The adult male moth is a fairly normal looking brown moth. But the adult female doesn't have wings and doesn't look like a moth at all. The adult female stays beside her cocoon, attracts the male moths via pheromones (scent), and then lays her eggs in the same spot.

Ambush Assassins
Out for a walk around Innovation Place at lunch time, I noticed a big bumblebee visiting a thistle flower. It didn't seem to be in a hurry to go anywhere so I pulled out my camera.
Looking closer, I saw there were several other bugs on the same flower. I took some photos and Seek later identified it as a Jagged Ambush Bug which is a kind of Assassin bug.
They are ambush predators like crab spiders, waiting on a flower and pouncing on visiting insects. If you look closely in the photo above you can see it has big front "claws" almost like a praying mantis.
Also like crab spiders, ambush bugs will take on prey bigger than themselves. But I think the bumblebee was a little too big. (The ambush bug is to the left of the bumblebee's head.)
Although the little ZS100 does pretty well at closeups, it would have been nice to have the big camera and macro lens. Although even a phone does pretty well these days, like with these Woodland Skippers.

Bat in the Boardroom
Boardrooms are visited by a variety of creatures, but most of them wear suits.
I'm not sure how this bat (Little Brown?) got inside our office.
It's amazing what evolution comes up with. Nice of it to show off its wing for me.
