Thar's gold in them thar hills?
Probably not. But thar's definitely gold in that there pollinator garden--our little pollinator garden in Vacaville, Calif.
Gold, black and white--as in the iconic monarch caterpillars.
We've been waiting all year for Mama Monarchs to lay some eggs on our milkweed. We planted four different species, watered them and watched them bloom, fade, and go to seed. The bees sipped nectar from the blossoms, aphids sucked the juices from the stems, lady beetles (aka lady bugs) ate the aphids, and milkweed bugs chewed on the seeds.
All was not going well.
At 9 a.m., we saw FOUR monarch caterpillars munching away on our potted narrow-leaf milkweed, Asclepias fascicularis. Then at 6 tonight, FIVE more on the same batch of narrow-leaf milkweed.
Just when I was thinking I wouldn't be rearing any monarchs this year (in 2016 the tally totaled 60 plus), one or more Monarch Mamas proved me wrong.
I placed the 'cats in a netted butterfly habitat from the Bohart Museum of Entomology to protect them from predators and give them a chance at life, a chance for another generation.
What's going on with monarchs in this area is not good.
Butterfly guru Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, who has monitored butterfly population trends on a transect across central California for 46 years, from the Sacramento River Delta through the Sacramento Valley and Sierra Nevada mountains to the high desert of the Western Great Basin, has not seen a single egg or caterpillar this entire calendar year at his low elevation sites.
"Not one!" he told Beth Ruyak on her "Insight with Beth Ruyak" program, Capital Public Radio, Sacramento, last week.
Shapiro, who maintains a research website at http://butterfly.ucdavis.edu, will talk about butterfly population trends (including monarchs) and how climate has affected them at a free public presentation from 6:30 to 7:30 p.m., Tuesday, Sept. 11 at Sierra College, Grass Valley. The event takes place in the Multipurpose Center Building, N-12, Room 103. Parking is $3; permits can be purchased at the kiosk machine at the main entrance to the campus. (For more information, contact the series coordinator, Jason Giuliani at firstname.lastname@example.org.)
And news flash: Shapiro spotted one monarch today, an adult female, in West Sacramento.
