I see the last incarnation was getting quite long so started a new version.

This flower Mary found this morning, a milkweed vine up on the front of our property in Arizona.

The view of the flowers here is 2cm across.

A giant leopard moth (Hypercompe scribonia) caterpillar I discovered crawling on my dry-stacked stone retaining wall yesterday. I couldn't resist taking a picture when it was next to a large section of pale green Montgomery County, Maryland beryl I collected and stuck in the wall as a non-structural "chink".

3rd Oct 2023 18:56 UTCAlessio Piccioni

Unfortunately I don't remember the name of the plant that produces these flowers, but I really like it because after the flower withers after a few months it begins to produce the seed which is first enclosed by small petals or perhaps small leaves which then open up when ripe. form like a new flower. In the attached photos you can see the three phases.

Luckily today I managed to photograph one of the last flowers.

Here's a photo of the primulas in my garden, absolutely love this flower...

3rd Oct 2023 20:20 UTCfsq (Mia Lane)

There's also this flower, the scientific name of which I do not know, so if you do, please let me know! (No, not a dandelion)

4th Oct 2023 11:50 UTCVladimir Sergienko

I think this is Kerria japonica, I'm not the slightest bit of an expert on flowers, so maybe my identification is wrong

In running a few specimens from the Dragoon Mountains through the sonic cleaner and bringing one quartz in to view under the microscope, this moss was perked up to nice and green after years in a box in the shed.

Reminded me of nice pyromorphite crystals but I knew immediately this was a "biological". View here is 1 cm.

8th Oct 2023 12:33 UTCVladimir Sergienko

Saccamoeba stagnicola is interesting because it forms triuret crystals inside itself; you can see the crystal as the brightest granule inside the amoeba

8th Oct 2023 13:04 UTCRolf Luetcke Expert

Vladimir,

sounds like having a "kidney stone" to me!

8th Oct 2023 16:49 UTCFrank Casella

I think this is a type of bracket fungus, Laetiporus sulphurous. New York state, Orange county.

8th Oct 2023 17:58 UTCMike Urbanik

More than likely sulphurous. A fantastic edible.

8th Oct 2023 19:10 UTCRolf Luetcke Expert

Frank,

Now that is probably the most picturesque shelf fungus I have ever seen, great photo.

Larry,

I have had those jump from the foliage and stick to ones cheek in Florida. Nice photo you got.

30th Oct 2023 14:28 UTCLarry Maltby Expert

I call it photo art.

We have had a lot of rain this fall in Michigan and the color was stunning. The storm clouds and the sky are dark and the driveway is wet. The delicate colors of the popular grove was too dark so I used photo shop to add some sunshine. The trees are now stripped of their leaves and when I woke up this morning there was white stuff in the grass.

30th Oct 2023 17:11 UTCHerwig Pelckmans

white stuff in the grass.

Did you order any minerals?

;-))

30th Oct 2023 19:05 UTCLarry Maltby Expert

No Herwig,

Before winter is over I will receive plenty of the white stuff without putting in an order.

30th Oct 2023 17:44 UTCMartin Rich Expert

Some days ago, I photographed this little guy. A fire salamander (Salamandra salamandra).

30th Oct 2023 19:20 UTCHerwig Pelckmans

Among my favorite salamanders!

I assume this one was "al-ready" for/in hibernation?

The contrasting colors can hardly get any better!

:-)

You will have to imagine this, because taking an adequate photo is beyond my capability. Today I was examining a crystal-lined cavity in a recently purchased micromount specimen and noticed several stands of spider silk which spanned the cavity. Attached to one of them were the remains of an extremely tiny spider. I did not have the heart to disturb them.

4th Nov 2023 20:28 UTCMartin Rich Expert

This is the end of the summer. Geese where flying today to the south. Flying in formation and the moon is also visible, a great photographing subject. Unfortunately, I can show only a lousy snapshot wich I made with my cellphone.

5th Nov 2023 22:30 UTCRolf Luetcke Expert

Kind of late in the season for toads to be out but this is our animal water bucket and the hardware cloth keeps animals which may fall in from drowning but allow things like drinking and toads to make use of the water. Since it has been very dry, the toad is making use of the water in the bucket before it goes underground for the season. This one is a spadefoot toad.

15th Nov 2023 16:46 UTCKim A. Strange

Came across this (these) little guy a couple of weeks ago. The hills are covered this time of year with Orb Weaver Spiders in elaborate webs. The combination of a light dew overnight and soft backlighting made this stand out.

15th Nov 2023 18:24 UTCRolf Luetcke Expert

Kim,

Many years ago, on a trip to Florida, I found a small dirt road I was able to get away from the main road to camp. The road had not been used except for garbage dumping, making a difficult place to get around but after I did, a pristine area to walk. I was walking down the tree covered road in late afternoon and suddenly stopped. The whole road was one giant spider web, with a near hand size spider. I stopped just in time, the spider was in the direct middle and that was exactly face level. We get the orb weavers here in Arizona as well, great spiders and nice photo with the dew.

15th Nov 2023 20:11 UTCKim A. Strange

Rolf, near hand sized spiders sounds like a horror film... they get up to 3 or 4 inches here with webs that can measure 3 feet or more - it always amazes me how they string their webs between trees that aren't touching - how do they do that?

16th Nov 2023 18:07 UTCRolf Luetcke Expert

Spiders use air currents to get their silk strand across open spaces. They let out silk until it attaches to something, test it and go across and make sure it is fastened tight, then build their large web. By the way, this is also how they spread out as tiny newly hatched spiders.

Saw this once in Summer when there was a big thunderstorm blocking one area with a darkness. I was in sunlight and looking up at the dark cloud saw hundreds of tiny rainbow threads. They were slowly lifting up into the sky. The baby hatchlings go up a tree to the top and let out silk. Weighing so little, the few feet of silk then outweighs the spiders and pulls them up into the air and they drift with the winds to disperse. They had taken special nets up in airplanes the height of commercial traffic and found a good number of these tiny spiders even up that high, truly amazing.

We have a phone pole where we were standing and the phone line was draped in lines of rainbows where the spiders webs hit the line and got entangled. A wonderful sight we have only witnessed one time.

15th Nov 2023 18:29 UTCRolf Luetcke Expert

Here is that Florida spider, a Golden Silk Orb-weaver-Nephilia clavipes. The web was a good 8 feet across.

15th Nov 2023 18:31 UTCRolf Luetcke Expert

This was another orb weaver spider, this one on Key West in Florida.

A friend of mine, told me about his friend Seamus who lived in the Bronx, NY and was hired to find spiders and snakes in Central America. He collected a 5 pound (2.27) kilogram spider which he kept in his apartment and said the Central Americans told him they had seen even bigger spiders. This plus the venomous snakes kept the undesirables from breaking into his unlocked apartment.

16th Nov 2023 18:14 UTCRolf Luetcke Expert

Tony,

I used the same "fear" in the uneducated living in Bisbee. A few houses up from mine was a family who's kids were terrors in the area. They broke into all the houses in the area and stole a lot of things. Having a pet rattlesnake in a cage in my house, the local kids, including the ones who kept breaking into homes would often stop by to see my latest animal I would bring home from the zoo where I worked. I told all the kids that knew I had a rattlesnake in the house, I would let it loose in the house when I went away on long trips to guard my house.

My house was never broken into and years later, the kids who had in the meantime moved away stopped by to visit the old neighborhood and I was out on my porch. The older boy's first question was if I still had that rattlesnake and let it loose when I left. Guess the "fib" I told sure worked since my house was the only one on the block that was never broken into.

16th Nov 2023 19:01 UTCHarold (Hal) Prior Expert

We had a similar situation many years ago with neighborhood kids breaking into houses. My "fear for the uneducated" was to post the following sigh on door. "Warning This house protected by ultraviolet radiation!". We were the only house that was never broken into!

16th Nov 2023 20:10 UTCRolf Luetcke Expert

Hal,

Those techniques do work.

I can add one more. I used to travel in Mexico a lot with a camper-van and often parked in out of the way places but even in those places, people roamed often. My preperation was to have 8x10 inch photos of a rattlesnake and one of a scorpion, in both side rear windows. With messages in Spanish of "peligro, viboras de cascabel, and alacran". I also had a jar of one pickled snake on the transit behind my front seat. Again, never got the car broken into in months of Mexico traveling.

Those things do work and yours is also quite good.

17th Nov 2023 13:16 UTCRolf Luetcke Expert

We feed birds here on our property and quail come to our feeders quite often. Found a quail feather but it was no longer attached to the quail. When you feed birds, the hawks also come to prey on the smaller birds and this quail was on the menu. All the birds do have to eat, including the hawks.

Been a while since the last time I shared (but always nice to come back and see all the new photos). Here's a few highlights frome one of my most recent trips. I spent a week in Olympic National Park in October. Olympic has three main habitats--the rainforest, the mountains, and the coast--with a plethora of different species in each, many of which are endemic. This first picture is a lipstick powderhorn lichen (Cladonia macilenta), named for the bright red tip that is a reproductive structure of the lichen.

18th Nov 2023 06:49 UTCKyle Bayliff

An Oregon ensatina (Ensatina eschscholtzii oregonensis). It's not apparent in this picture, but this one was missing most of its tail. It had a little nub where the new one had just started growing. Uninspired as it may be, I named it 'Stumpy'

18th Nov 2023 06:55 UTCKyle Bayliff

A Pacific oak fern (Gymnocarpium disjunctum). This species of fern changes color in the Autumn. However unlike the vivid colors of the maples, the oak ferns turn white. I like these because of their somewhat skeletal appearance.

18th Nov 2023 06:59 UTCKyle Bayliff

A western red-backed salamander (Plethodon vehiculum). Probably the most common salamanders in the Park, but a new species for me. These guys move fast, though. This one scrambled into the underbrush before I could get any more pictures.

18th Nov 2023 07:05 UTCKyle Bayliff

Not the greatest picture as I was a little far away, but watching the coho salmon (Oncorhynchus kisutch) running up Sol-duc Falls was one of the top highlights of the trip. There was a pool a little further downriver where the fish rested before making their attempts at the falls. I saw many make it past the first tier of the falls with some truly impressive jumps (and many others collide very solidly with the rocks), but not one made it up the second tier while I was there.

18th Nov 2023 07:10 UTCKyle Bayliff

Olympic had more fungi than you could shake a stick at. I found over 50 different species (though many I have yet to identify). This bulbous honey fungus (Armillaria gallica) was one of the more photogenic varieties.

18th Nov 2023 07:19 UTCKyle Bayliff

Here's one of the endemic species I mentioned. This is an Olympic torrent salamander (Rhyacotriton olympicus) that I found in a small waterfall on a hillside. This one was maybe as long as my pinky finger. It's cropped out in this picture, but I stucks some wet moss and mud in my gold pan to keep it moist, but it wasn't very interested in getting comfortable. It stopped crawling just long enough for a picture, then I let it go back in the waterfall.

18th Nov 2023 07:25 UTCKyle Bayliff

Animals were a little scarce on the alpine trails. The marmots had already started their hibernation, unfortunately, but the rocks along the Hurricane Ridge trail didn't disappoint. Lovely dendrites like these, some with tiny crystals, interesting foliation, etc. I wish I had brought my magnifying loop on that trail.

18th Nov 2023 07:32 UTCKyle Bayliff

The coast was a little disappointing. The tide was up on the day I explored the coastal sections of the park, so no tidepooling, and I didn't spot any of the whales I was hoping for. I spotted a harbor seal and a bald eagle from a distance, but that was about it except for the gulls. The beaches had some interesting geology, though. This layered rock was turned almost vertically and I found some nice tafoni formations as well.

18th Nov 2023 07:36 UTCKyle Bayliff

One of the ubiquitous banana slugs (Ariolimax columbianus) on a log covered with moss and honey mushrooms. The Park must be a paradise for them.

Always nice to see your photos and nice to see "green" since we are in drought central here in SE Arizona.

Thanks for posting a nice group of your photos.

18th Nov 2023 13:33 UTCErik Vercammen Expert

Thanks! Always something new to learn.

18th Nov 2023 18:06 UTCKyle Bayliff

Thank you to David for posting the informational link. Erik, here's an example of the tafoni that occurs along the Olympic coastline. It occurs in the same layered rock I showed (limestone in this case, I think?). I have seen more impressive tafoni formations elsewhere, though. Salt Point State Park in California has an impressive amount along the coastal section of the park, though that occurs in weathered sandstone.

18th Nov 2023 16:09 UTCRolf Luetcke Expert

Bit of a story. The Tarantula Hawks are always so active and getting close enough for a photo is very difficult. The story here is years ago, going to the landfill to toss out trash, someone had tossed two plastic outdoor chairs. They were still in decent shape so we took them along, not for sitting but to put out near the house for water for the birds to take baths in. This time of year, we put in the sugar water to feed the bees. They come in hundreds and we like helping them out and they finish the sugar water in a couple of hours. This early morning we put out the sugar water and a tarantula hawk was also on the chair. It was still slow and wet from the nights dew. So, got some nice close up photos. Those thrown out chairs have been used this way for close to 20 years now and both birds and insects get to enjoy them.

Sarah,

Our birds only go off for a little while and come right back. They keep a close eye on where the hawk goes and when it moves on to check other areas, they come back.

Posted the photo of this yucca that the cattle pulled over to eat the flowers on the top stalks this Spring and just walked by it again and saw it was sending up a new sprout from the root still in the ground. Will take a number of years for it to attain the size of the one knocked down but it shows the resiliance of desert plants.
