Yellow-headed Caracara (Daptrius chimachima) Yellow-headed Caracara from Commerce St, Wilmington, DE, US on November 20, 2025 at 03:38 PM by Matt Felperin. Continuing 1st state record initially reported by Jeanette Sloper on 11/18. Moving aroun...

πŸ€πŸ“°: There's apparently a yellow-headed caracara in the USA. Per speculation on Facebook, maybe traveled to Wilmington, DE, via the banana-laden Chiquita Explorer from Honduras. One person said she saw it near the Blue Route / I95. Great pics on iNaturalist. #delco www.inaturalist.org/observations...

Read The Book Journey to rainforests, volcanoes and ancient temples to discover the mind-blowing story of the strangler figs and their kin, which have shaped our world and our species in many extraordinary ways.

I highly recommend Gods, Wasps and Stranglers. Terrific read. planetficus.substack.com/p/the-book

Not a tiny bird's nest, this cute little mossy cup is the remains of a green lacewing cocoon!

If you've seen a crawling piece of fluff it's almost certainly one of these little trash monsters, hiding from predators & prey. Adults look like this: flic.kr/p/2jZaTAQ

I think there are three genera of parasitoids that attack fig wasps: Sycoscapter, Philotypesis, and Apocrypta (all in the Pteromalidae). I'm not really sure which fig wasp species they attack (they all specialize). I think the first two have representatives in California.

If you encounter a wild fig in California, I highly recommend dissecting some of the fruit to see what's inside. You might even get lucky and see wasps trying to get into the fruit. Bonus points for pics of Sycoscapter, a chalcid that is parasitic on fig wasps. www.inaturalist.org/observations...

This is where fig wasps get into fig syconia. And where the next generation escapes. It's called the ostiole.

The California Fig Advisory Board, a lobbying group, says that only 1% of the state's fig trees require wasps for pollination. What they don't advertise is that these trees can still be visited by the millions of wasps that emerge from nearby, wild fig trees. #figs californiafigs.com/faq/#:~:text...

Until recently @ymilesz.bsky.social taught me, I didn't know anything about the fascinating synbiotic relationship between fig trees and fig wasps. So I've been wanting to see their work in the wild, and found it on the last day of #September2025GallWeek !

My photo shows a three quarter profile of an ancient Egyptian figurine of a leaping dog facing left. Carved from ivory, now a warm caramel brown colour with glossy surface. The dogs eyes are outlined in black, the ears are floppy, the mouth is slightly ajar (the inside of the mouth is painted red - not sen in my photo). The front and back legs are outstretched as if running at full speed. A lever under the dog’s chest opens and closes the mouth so that the dog looks as if it’s barking. Dimensions: L 18.2 cm Γ— H 6.1 cm Γ— W 3.6 cm. Dated to Late Dynasty I8, I400-I350 BC, reign of Amenhotep III who was Tutankhamun’s grandfather.

The dog is mounted on a thin metal rod in a display case. In the background in the same display case is a β€˜galloping’ brown horse, which is the handle of an ancient Egyptian fly whisk or light whip.

A macro photo of just-hatched, nearly transparent earwig babies, along with several still-unhatched eggs. The only pigment on the babies is in their compound eyes and mandibles, which can even be seen through the shells of the eggs that are yet to hatch.

--pigment on their eyes & mandibles. Why? My guess is, if you think about it, a transparent eye can't trap light, so to be useful it needs pigment. As for mandibles, they need to be tough enough to bite food (one here is already nibbling its empty eggshell) and melanin hardens (sclerotizes) them.

Be honest, could you tell this was a diorama?
Haus der Natur in #Salzburg uses many tricks to make viewers believe they're seeing a wild scene: high-quality #taxidermy, outstanding background painting with perspective to give depth, and hiding the point where the painting meets the 3D foreground. 🐐

Harvested 63 persimmons this year, almost twice the number from 2024. And lost only one to the squirrels, compared to perhaps 10 last year.

I was too young to remember exactly how my parents did the collecting and de-husking, but a podcast I recently listened to suggested that shaking the tree would dislodge the fruit a few days before they'd normally drop, and I think the discoloration (from larval activity) might be less noticeable.
