Monique Keiran: For butterflies, mythology lives on in descriptive names.

We can thank a 312-year-old Swede for making a harmless bug-hunting hobby seem like tempting fate with capricious Greek gods. In the mid-1700s, Carl Linnaeus revamped the way we classify, categorize and name living things in related groups. He leaned heavily on the Greek and Roman classics when he named the butterfly groups.

And so we have the Parnassian butterflies — found in mountain meadows — and the Satyrids, Nymphalids and Danaianids, as well as species such as Danaus plexippus, Polygonia faunus, Parnassium phoebus and Phoebis sennae. These are scientific names, based on the two-named system to distinguish genus-plus-species that Linnaeus put in place and is still used in biology today.

A Look at the Science of Insect Conservation.

Western monarchs migrate to California annually to overwinter in coastal groves. In her study, Schultz analyzed data reported by the Xerces Society, collected from 1997 to 2016, about monarch populations in the coastal groves, as well as some older data. Schultz found that the average abundance of the western monarch in 2016 was less than 5 percent of the abundance in the 1980s. “What we think we’re seeing is a long-term decline related to threats of habitat loss and pesticides,” she says.

We don't know why this year's numbers may have surpasses last year's.

But what we do know, they will head to the foothills by September where they will hibernate, and head back to the Sierra next spring.

The California Tortoise Shell can live up to 10 months as adults.

Each fall, the Western monarch butterflies migrate from Southern California to Central California where they stay huddled by the thousands — with their wings closed — until February, when they mate and begin their migration back south.

Butterflies are More than Party Favors.

“Butterflies raised by unregulated commercial interests may spread diseases and parasites to wild populations, with devastating results. Often, butterflies are released great distances from their points of origin, resulting in inappropriate genetic mixing of different populations when the same species is locally present. When it is not, a non-native species is being introduced in the area of release. At best, this confuses studies of butterfly distribution and migration; at worst, it may result in deleterious changes to the local ecology.”

Scientists scramble to learn why monarch butterflies are dying so quickly.

A smaller monarch population in the western United States that migrates between California and the Pacific Northwest is disappearing even faster, dropping from 1.2 million in the 1990s to just 30,000 last year -- a 98 percent drop.
