From September, but suitable for #Stunday -- American Lady spotted amidst a cornfield nearly ready for harvest

Such an unexpected splash of colour!

To jump onto the lap, or not to jump onto the lap

Big question for a #Caturday morning

#Tortoiseshell
Tortoiseshell cat sits on rug looking up at her owner's lap (inferred from the fact that we can see two legs ending in sheepskin slippers).

Aerial view of possible detente over the hot air register in the bedroom. It's usually Misty's domain but Mao the farm cat now wants in and is playing all charming in her advances

#CatsOfBluesky
#Tortoiseshell
Two cats on hardwood floor near a corner in which a hot air register is mounted. One is a greyish-white longhair and the other is a Tortoiseshell. The latter looks as if she is asking for a place near the warm air and the former looks as if she might just grant that privilege.

My kind of weather for Thanksgiving Day -- cloudy and grey, with a dusting of snow.

#HappyThanksgiving
View of snow-dusted hillside with three tall trees centered upon it and more trees in the background. We see the side of a red barn off to the left at the bottom of the hill.

I was fortunate enough to see an aberrant Pearl Crescent this summer, and even catch it mating with a regular specimen!
Two Pearl Crescents, one aberrant, are mating in grass. The aberrant specimen has larger blotches of taupe and orange than the regular form.

Rainbow Mao!

Her mottled tortoiseshell fur is further enhanced by the sunlight refracted through leaded glass

Perfect for #Caturday

Another spectacular display this evening

St. Croix County, Wisconsin

Nature is amazing

#Aurora
#Naturephotography
Dark sky lit up by the surreal colours of the northern lights. Clouds of green and pillars of magenta glow over a dark meadow.

I'm typically the same -- dropping everything to go out -- but I didn't feel well last night so went to bed early. Awoke around 11:00 to find the bedroom bathed in this eerie glow. I literally took this photo out the window from my bed. Never had the lights "come to me" like that!

Awoke just after 11:00 last night to a strange glow in the bedroom. Looked out the window to see Aurora borealis bathing our entire valley in red, upstaging the lights on the cell tower.

The newly-harvested cornfield seemed to reflect the colours in the sky.

#Naturephotography
View of a small rural valley over which the northern lights are glowing in red, pink, and green. A cornfield, just harvested, reflects this light.

Prairie sky at sunset last night

The bleakness of November creates such drama

#Naturephotography
A sunset sends rays of light into blue-grey clouds filling the sky over a meadow and, behind it, a cornfield just harvested

Recycling this photo from mid-July for #Stunday

Female specimen of the Eastern Tailed-Blue, which has been nominated (by @butterflyguy99.bsky.social) as the real species closest to the bsky logo

Not as showy as the male, but possessing a shimmery beauty all her own

I agree! Here was one of my better shots of this guy (yes, the blue is male!) this summer

I humbly submit that we do NOT need AI to analyze our cats' litter box behaviour

#Caturday
#JustSayNoToAI
Part of a flyer for some god-awful contraption for monitoring litter box activity. The headline is "What Can Litter Box Behaviour Tell Tou?" and various images of trend data and AI-generated text surround a photo of a poor, unsuspecting cat. More ridiculous claims from the flyer for a product that promises to transform litter box behaviour into "smarter care."

Percy has had every opportunity to sit here before, but it was only when I left some papers atop the little sewing chest that he determined it was a cat-ready perch

Happy #Caturday
Interior shot of a black cat sitting on top of a small chest in front of a window, with plenty of sunshine streaming in. The cat is looking over his shoulder at the photographer, whose papers are now in all likelihood covered in cat hair.

I hereby announce that I am a global citizen! Does this mean I can move to the UK and join #TeamMoth to escape this dystopian nightmare? I have my moth credentials handy!

#Moths
#MothsMatter
A "certificate of participation" issued for taking part in National Moth Week. It is decorated with a composite image of colourful moths, some of which may not actually exist, and a congratulatory wish is "signed" by various scientists. This participant is hoping that the certificate will open many doors.

Complementary colours. Eau Claire University campus on #NoKings day. Posting a week late for #Stunday
Sideways view of a stately classroom building in red brick. Directly beneath the first-floor windows are hydrangeas with pink-tinged blossoms, and in front of them, yellowish-green hostas.

Those eyes!

Happy #Caturday from Mao the #Tortoiseshell
Black cat with the deep reddish-brown swirls that give it the 'tortoiseshell' label sits in a ray of sunlight on a green and black rug. Her greenish-yellow eyes glow in the reflected light.

A not-too shabby White-Speck this #MothMonday morning. After ten days of nearly nothing, I'm happy.

Close-up of a moth with wings coloured by a rich palette of grey, taupe, pale peach, gold, and ... well, there are just a lot of subtle shades in there! The moth is clutching the end of a stick.
