Blue Banded Bees are amongst our most beautiful Australian native bees. They are about 11 mm long and have bands of metallic blue fur across their black abdomens.

Blue Banded Bees are solitary bees. This means that each female bee mates and then builds a solitary nest by herself. She builds her nest in a shallow burrow in clay soil or sometimes in mudbricks. Many Blue Banded Bees may build their nest burrows in the same spot, close to one another, like neighbouring houses in a village.

Blue Banded Bees can perform a special type of pollination called 'buzz pollination'. Some flowers hide their pollen inside tiny capsules. A Blue Banded Bee can grasp a flower of this type and shiver her flight muscles, causing the pollen to shoot out of the capsule. She can then collect the pollen for her nest and carry it from flower to flower, pollinating the flowers. Quite a few of our native Australian flowers require buzz pollination eg Hibbertia, Senna.

Tomato flowers are also pollinated better when visited by a buzz pollinating bee. Researchers at the University of Adelaide made substantial progress in developing native Blue Banded Bees for greenhouse tomato pollination.

It would be much better for our environment to use our native Blue Banded Bees for this purpose rather than introducing European Bumblebees to Australia! (European Bumble Bees are not found on mainland Australia. Instead, native Blue Banded Bees and Carpenter Bees fill the niche of buzz pollinators on the mainland.)

Parrots are known for being adaptable, but you might not expect to see them in the trees of snowy Stuttgart. Yet it’s true: Around 50 yellow-headed Amazon parrots live in this German city. And they don’t just survive here – they thrive.

From making the most of the daily commute to major success in breeding, the Stuttgart parrots are of great interest to conservationists. With wild parrot numbers in sharp decline and more cities across the globe reporting urban parrot populations, could they offer hope for their species’ future?

The Southwestern Speckled Rattlesnake exhibits great variability throughout their range. Their coloration generally matches the tones of the rocks found within their habitat. This, the white variant, lives in an area where the granite is light in coloration with dark flecking.

I rarely record my wild howlings. There have been many times when I have traversed solo into the forest, or into the desert, & have shrieked... just simply for the joy & pleasure it brings. Same thing with running around nude amongst the wilderness. There is just something so vastly freeing & liberating about it. May this post here be a testament for all to embrace your inner animal, in a fun & safe way. To take a break from the concrete jungle & to fully immerse yourself in the natural one. I promise you, that you will be thankful you did.

Tyrant lizard king? No thanks, fuck the monarchy. Spinosaurus is cooler anyway (the modern depictions of him, not the terrible Jurassic Park version). hell yeah, look at that crocoduck and his powerful tail, I bet he could just smack T. rex with that tail and it would be over.

Did you know a crocodiles tail is just as dangerous at its jaws? That shit is pure muscle for swimming, it can break bones. Big heavy theropods like T. rex are fucked if they get a broken leg.

I prefer herbivorous dinosaurs though. Therozinosaurus is hilarious and I love him. BEHOLD

I love garter snakes so much, this one was curious and friendly and slid right across my leg after telescoping a bit for me to take a photo.

After years-long discussion, birds will no longer be named after people — a decision meant to dissociate the animals from problematic eponyms.

The American Ornithological Society announced Wednesday that all common English-language names of bird species named after people will be changed, along with other monikers that have been deemed offensive. In total, approximately 70-80 birds — primarily in the US and Canada — will be renamed.

“There is power in a name, and some English bird names have associations with the past that continue to be exclusionary and harmful today,” said Colleen Handel, president of the AOS, in a statement.

Many birds sport names that come from White men with “objectively horrible pasts,” according to the group Bird Names for Birds, a grassroots initiative that has been advocating for this change. Having their names memorialized in this manner is similar to building a statue in their honor, the group argues.

The Hammond’s flycatcher, for example, is named for William Alexander Hammond, a former US surgeon general. Hammond held racist views toward both Black and Indigenous people, writing that Black people specifically were of “little elevated in mental or physical faculties above the monkey of an organ grinder.”

Judith Scarl, the executive director and CEO of AOS, said in a statement that there has long been historic bias in how birds have been named, and scientists should work to eliminate that bias.

“Exclusionary naming conventions developed in the 1800s, clouded by racism and misogyny, don’t work for us today, and the time has come for us to transform this process and redirect the focus to the birds, where it belongs,” she said.

Though efforts toward renaming birds existed before, the movement gained momentum in 2020, in the midst of large-scale cultural upheaval surrounding racist or otherwise offensive names — like those of sports teams and school buildings. That same year, Christian Cooper, a Black birdwatcher, made headlines after a White woman called the police on him — highlighting some of the prejudices Black people face in the outdoors.

In 2021, the AOS announced an ad-hoc committee to make recommendations regarding these common English names. The committee was formed in 2022 and released its guidance earlier this year. Wednesday’s move by the AOS is in response to those recommendations, and the renaming project is set to begin next year.

These Tiny, Beautiful Wasps Eat the Hearts Out of Cockroaches - The New York Timesarchive.today • These Tiny, Beautiful Wasps Eat the Hearts Out of Cockroaches - The New York Times

If you loathe cockroaches, you’re going to love the emerald jewel wasp.

Females of the species Ampulex compressa, known also as emerald cockroach wasps, are less than an inch long, and decked out in gorgeous, metallic green-blues. To complete their life cycles, they must first sting an American cockroach, and inject the much larger insect with mind-control toxins that turn it into a defenseless zombie.

Next, the female wasp drags the subdued cockroach by its sensitive antennae into a cavity it has found, lays a single egg on the roach’s leg and then uses dirt and debris to seal the fateful pair inside. After six days, the egg hatches, and the larva carves its way inside the cockroach’s chest. It then begins devouring the helpless insect from the inside out.

After six days, the egg hatches, and the larva carves its way inside the cockroach’s chest. It then begins devouring the helpless insect from the inside out.

It is one of the more macabre horror stories you will find in nature, and just in time for Halloween.

Gruesome as it is, there are around half a million species of parasitic wasps on this planet, and many make their living in a similar fashion. Scientists love to study these mini-monsters because many wasps zero in on insects that humans don’t really mind seeing brutalized: creatures like roaches, but also crop pests and invasive species.

But there’s something scientists never noticed about the jewel wasp’s “Cask of Amontillado” routine until now.

“Since the 1800s, people have sort of had this mantra that parasitoids selectively avoid eating the vital organs of their host so that they can keep it alive,” said Kenneth Catania, a neuroecologist at Vanderbilt University. “And what I have found is that this parasitoid goes straight to the heart of the cockroach, and eats it.”

Each fall, Dr. Catania prepares a special, Halloween-themed class for students of his Neurobiology of Behavior course. One year, he even built a three-room, Wes Anderson-style diorama and filmed a wasp dragging its victim through a dollhouse-size kitchen full of tasty, tiny treats and into a tomb shaped like a human skull.

To be clear, the video is meant to be silly and engaging, the better for students to learn how the wasps operate. But behind the cutesy props, it also shows real ecology in motion. The wasp performs her task perfectly, even going so far as to seal the skull’s eye socket with tiny bits of golden plastic treasure, just as Dr. Catania hoped she would.

And so, in another attempt to win his students’ attention, the scientist set out to film an emerald jewel wasp larva as it feasted on the cockroach from within.

“That’s the way science often unfolds for me,” said Dr. Catania, the author of “Great Adaptations.” “I’m looking at something out of curiosity, or art.”

This is how he ended up capturing the larva’s taste for cockroach heart. But he made an unexpected discovery: After eating the heart of the cockroach, the wasp larva started gnawing at its quarry’s trachea, the insect equivalent of lungs. This caused air to leak out of the cockroach’s respiratory system and into its body cavity, air that the wasp larva then eagerly slurped up.

In other words, the emerald jewel wasp both eats the cockroach’s heart out and takes its breath away.

After performing the experiment two dozen times, Dr. Catania was able to show that not only do the air bubbles allow the larva to breathe while fully inside the cockroach’s body, but they also give the little hell-raiser a metabolic boost. Once the air bubbles appear, the larvae start to chew faster, which Dr. Catania documented this year in a study published in the journal Current Biology.

Within 48 hours, the emerald jewel wasp larva has chewed its way through so much cockroach that the host dies. “You can imagine it sort of like ‘Alien,’” said Dr. Catania, referring to Ridley Scott’s 1979 film. “Once it’s inside you, it’s game over.”

In fact, the game ends much faster than has been observed with other parasitoids, some of which don’t even fully kill their hosts at this stage, but rather keep their victims on life support by avoiding vital organs. That led Dr. Catania to ask why these wasps evolved to consume with the speed of Joey Chestnut.

That sets up a perfect cliffhanger for a sequel to this natural slasher flick: Dr. Catania believes the wasp has to eat quickly before its zombified host is eaten by, well, something else. But that’s a discovery he’s not yet ready to publish.

“There’s more to this story,” he said, “and I’m currently working on the second part.”
