Also, this continued video quality issue is the main reason I find myself going back to IG. @bsky.app :/

This piece is called “Deer Resistant My Ass!”
We have a few painted rocks around our garden. After deer browsed my evening primrose literally the day I planted it, I thought about a rock with this quote. Then was like “wait. I have a bandsaw.” #nativeplants #starwars #failure Oenothera biennis

I found a dead fly in my yard. Turns out it’s zombie fly infected with a fungus that makes it find a high perch, spread its legs/wings, die, and release fungal spores below. I’ve found 3 now, with 1 shipped to @zombiflied.bsky.social at Harvard for science! Just in time for Last of Us finale! 😂

After 87 years, zebra swallowtail butterflies return to Pittsburgh thanks to pawpaws Although its host plant is native to Pittsburgh, no sightings of zebra swallowtail butterflies had been reported in 87 years. Until now.

And this excellent @nextpittsburgh.bsky.social article by Andy Moore gives a lot more history, research, and context!

Long-gone zebra swallowtail butterflies in my Pittsburgh pawpaws Naturalists waited decades for the zebra swallowtail butterfly's return to the northern end of its habitat. My pawpaw trees bred hope.

This was my original story in @publicsource.org: www.publicsource.org/zebra-swallo...

It happened! At least 4 of the 32 zebra swallowtail #butterfly chrysalises that overwintered survived (maybe all). The 1st eclosed today! This shot was NOT planned. 3 more coming in the next 1-2 days. All offspring of this single mom: www.publicsource.org/zebra-swallo...

Another tiny strip of lawn I’ll never mow again! The other side is neighbor‘s lawn. Shrubby St. John’s wort + foxglove beardtongue from seed. I’ve solarized w/cardboard/mulch around plantings before. Works well enough. If the deer strike and I need to replace, well the hard part’s done.

Just perusing through your native plant photos. :) this one reminded me of some NE aster shots I took this week! Yes, really. I grew them from seed under light in my basement. Then took them in and out trying to harden them while avoiding freezes. They’re so confused 😵‍💫 😂. I was shocked.

That’s great to know! Although these deer will keep coming back over and over. City deer… haha. I had read that oenothera are deer-resistant. That clearly does not apply to starved urban deer. 😂 or just bad internet info

Yes the “stairs” were haphazardly thrown together today. Squirrels will ruin it regularly anyway.

Made a new #hobbit hole for our front garden. Partly to make kids/parents smile when they walk by. But mainly to make myself smile. Scrap fence cedar and acrylic paint. It’ll look better with real plants around it I think. Pieces cut on #scrollsaw. #woodworking #geekart

Current vibe post Chewie’s “cryptorchid” surgery. Fun tangent: this lead to me learning that “orchid” means “testicle.” Hat tip to @metalmarks.bsky.social for sharing this illustration of why the plant is called an #orchid in our Pittsburgh #Naturalists signal chat. #DogsofBluesky

Cold & rain makes for a great day to do my annual refinish of this inlayed patio sunflower table I made. Downside of oil-finish: yearly maintenance. Upside: it’s easy and much prettier than something like spar urethane. It stays on our porch so at least somewhat limited exposure to elements.

Purely based on my 1 successful attempt at doing exactly this: don’t give up hope on them if it takes FOREVER for them to pop out. Haha. Mine took like a couple months to germinate (I tried scar vs non-scar, fridge cold strat vs fall sow). But everything ended up growing after a few months.

Wooden monarch hindwings being glued.

Wooden monarch forewings being glued. A scrap piece of ash superglued to the backer. And scrap walnut wedge gives clamping pressure.

Next 2 stages of glue up. Since body is glued, I 1st did the bottom wing, pressing them toward center with cauls. Then repeated with forewings. You can see the cauls (a superglued scrap and a wedge) in the second photo to apply clamping force. The pieces interlock at the body creating a pivot point.

1 step of glue up has begun. I usually find it helpful to glue at least 1 piece to serve as a stable reference when I go to glue the rest. Tiny errors are additive (especially with over 300 individual pieces of wood). So it’s best to take it in stages. I’ve never had a stress-free glue up. 😂
