Leafcutter bees are solitary, gentle pollinators that construct leaf-based egg chambers, provisioning them with nectar and pollen. A female may create up to 20 such cells, like the one seen in this footage of a bee emerging in the UK. Many species exist globally, including 63 in Florida.

Bees are also remarkably complex. Expert Stephen Buchmann notes they feel emotions, process long-term memories during sleep, and may even dream, raising ethical questions about their treatment. Learn more about bee intelligence: [here](https://biodiv.us/3n2sePr).

Mexican gray wolves, also known as lobos, are a highly endangered subspecies. The Center for Biological Diversity, a 501c3 nonprofit, spearheaded their reintroduction to Arizona’s Apache

Mexican gray wolves, also known as lobos, are a highly endangered subspecies. The Center for Biological Diversity, a 501c3 nonprofit, spearheaded their reintroduction to Arizona’s Apache National Forest in 1998. Since then, we have worked tirelessly to protect these unique wolves from persecution and boost their declining genetic diversity.

Today, 241 lobos roam wild in Arizona and New Mexico, with 380 in captive-breeding programs. Despite this progress, they remain among North America’s most endangered mammals. We are committed to their full recovery, believing that human welfare is deeply linked to the vast diversity of wild animals and plants.

Dr. Justin O. Schmidt, a renowned entomologist and ally of the Center for Biological Diversity, famously endured approximately 1,000 insect stings to create his unique Pain Index. This index comically rated and described the intensity of stings, from the "light, ephemeral" sweat bee to the "pure, intense" bullet ant. Dr. Schmidt passed away on February 18, 2023, at 75.

After weeks of protests, legal action, and public comments, the last shipping container from former Arizona Gov. Doug Ducey's rogue border wall was removed. This anti-immigrant symbol sliced

After weeks of protests, legal action, and public comments, the last shipping container from former Arizona Gov. Doug Ducey's rogue border wall was removed. This anti-immigrant symbol sliced through a vital wildlife corridor, impacting endangered jaguars and ocelots. The Center's Russ McSpadden called it "perhaps the only major border wall removed globally since the Berlin Wall." Taxpayers, however, still pay millions for Ducey's destructive stunt.

Male mason wasps have evolved a unique defense: using spiked genitals to mimic a female's venomous sting. Lacking true stingers, males deter predators like tree frogs by faking one with spines on their reproductive organs. A 2022 study found this strategy 35% effective, compared to females' 87% escape rate with real stingers.

Scientists recently discovered bats, like Tuvan throat singers and death-metal vocalists, produce sound using ventricular folds instead of vocal cords. A Danish biologist found bats use these for low-frequency calls. With their ability to also make extremely high-pitched calls, bats possess an unparalleled vocal range. The Center for Biological Diversity argues this makes them more akin to grindcore vocalists, who utilize both very low and very high frequencies.

Scientists recently filmed octopuses throwing seashells and debris at each other, possibly for social reasons. This adds them to a select group of animals known to hurl objects. Females initiated most throws (66%), often during mating, with 17% hitting their underwater targets.

After five years of legal action by the Center for Biological Diversity, the U.S. Fish and Wildlife Service finalized Endangered Species Act protection for the Dixie Valley toad. These extremely rare amphibians, previously under emergency protection, face acute threat from a geothermal power plant likely to dry up their critical hot springs. As the Center’s Great Basin Director Patrick Donnelly stated, "Renewable energy is essential to combating the climate emergency, but it can’t come at the cost of extinction."
