California Has 50 Times More Monarch Butterflies Than Last Year

California's monarch butterflies were teetering on the brink of extinction, but a promising rebound may buy more time to save them.

So Far, 100,000 Monarch Butterflies Migrated in 2021. Can This Stop Their Extinction?

Tens of thousands of monarch butterflies are flocking to the California coast for the winter, filling tree branches with fluttering orange wings – a remarkable rebound from years of near-extinction.

Recent Decline of the Monarch Butterfly Linked to Climate Change

Danaus plexippus) in North America, as well as the possibility of its breeding range becoming inhospitable if global warming shall persist. (Photo : Photo by Chris Chow on Unsplash) Monarch butterfly (Danaus plexippus) feeding on sedum flowers The insect is known for its extraordinary migration from Mexico off north to their breeding grounds in the US, then south in the autumn to shelter against North American winters, and then fly north again in early March. So far, the reason why butterflies leave the relative warmth of Mexico and go back to the US has not been figured out. From the looks of it, cold weather could be their decisive factor, which implies that monarch behavior could change profoundly over the coming decades if the globe warms persistently.

SANTA CRUZ, Calif.— Migratory western monarch has declined by more than 99% since the 1980’s. The Xerces Society, an international invertebrate conservation nonprofit, reported that the total number counted in 2020 was down to 1,914, a drop by more than 90% from the prior year — a count already below the threshold at which scientists warned the migration may collapse. To help scientists gain insight into migratory monarchs this spring, researchers are inviting the community to participate in the Western Monarch Mystery Challenge. The challenge was started by a group of researchers from Washington State University, Tufts University, University of California at Santa Cruz and the Xerces Society to help fill a critical gap in knowledge about habitat needs of migrating monarchs in the spring. Running from Feb. 14 (Valentine’s Day) to April 22 (Earth Day), the challenge is a call to action to report a monarch if you see one. Once you report a sighting, you will be entered to win prizes.

U.S. agency sidesteps listing monarch butterflies as endangered

Share Illegal logging at wintering grounds in Mexico contributes to the monarch butterfly’s decline. FRANS LANTING/MINT IMAGES/SCIENCE SOURCE U.S. agency sidesteps listing monarch butterflies as endangered Dec. 15, 2020 , 6:20 PM The U.S. Fish and Wildlife Service (FWS) announced today it will not yet protect one of North America’s best known butterflies under the Endangered Species Act. The agency concluded that the iconic black and orange monarch ( Danaus plexippus) has suffered population declines steep enough to possibly qualify for federal protection, but FWS will take no action at this time because 161 species already being considered for the list are a higher priority for support from the agency’s limited budget.
