Painted Lady Butterflies in Upper Las Virgenes Canyon Open Space Preserve

Painted Lady Butterflies in Upper Las Virgenes Canyon Open Space Preserve. May 12, 2019.

Back in March, a profusion of painted lady butterflies in Southern California made headlines. The colorful insects were said to be passing through the area on their way to Oregon and other points to the north.

Two months later millions of the black, orange and white butterflies continue to be seen in the West San Fernando Valley, Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch), and other areas. Recently there has been an uptick in their numbers and there have been some remarkable displays of the flyers along local trails.

There are three very similar species of “lady” butterflies in the genus Vanessa — the painted lady (Vanessa cardui), the American lady (Vanessa virginiensis) and the west coast lady (Vanessa annabella). The Canadian Biodiversity Information Facility web site has a side-by-side comparison of these species and this post on BugGuide.net compares the American lady to the painted lady.

The lady butterflies I’ve looked at closely in Upper Las Virgenes Canyon Open Space Preserve have the identifying characteristics of the painted lady (Vanessa cardui). Here are an open-wing photo and a closed-wing photo of painted lady butterflies in Upper Las Virgenes Canyon Open Space Preserve.

This three-minute slow-motion video of painted lady butterflies in upper Las Virgenes Canyon reveals their fluid, bird-like flight. The purple flowers in the video are winter vetch, an introduced plant which is also more abundant this year.

Chinese Houses Along the Sheep Corral Trail

Wildflowers continue to flourish following our wet rain season. Above average precipitation tends to produce more wildflowers, a wider variety of wildflowers, larger patches of a wildflower species, larger plants, and in some cases larger blossoms.

During the week I photographed several new “Weekday Wildflowers” on runs from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve. This week’s runs included Lasky Mesa, Upper Las Virgenes Canyon, and the Sheep Corral Trail.

Chinese houses, white snapdragon, yellow monkey flower, stinging lupine, and a few other species were added to the Weekday Wildflowers slideshow.

Weekday Wildflowers

Goldfields along a trail in Upper Las VIrgenes Canyon Open Space Preserve

Many of my weekday runs are on the trails of Upper Las Virgenes Canyon Open Space Preserve (formerly Ahmanson Ranch).

In the wake of the Woolsey Fire and our wet rain year, the hills of Upper Las Virgenes Canyon Open Space Preserve have been covered with a dense carpet of green that has recently transitioned into a sea of mustard yellow. The grasses have now gone to seed and the hills will soon turn a summery-blond.

At first glance, just about all you see at Ahmanson Ranch is the green and yellow. But if you look closer, intermixed with the black mustard and other introduced plants are a variety of wildflowers.

In a few areas of the Preserve, there are large patches of native wildflowers, but it is more common for the native flowers to have to battle introduced plants for growing space. Some species are more successful than others.

Here is a slideshow of the wildflowers I’ve been seeing on my weekday runs, along with some comments and the date the photo was taken. Some of my weekday runs extend into Cheeseboro Canyon, so wildflowers from that area are also included. Additional photos may be added as the season progresses.

The yellow flowers along the trail on which Lynn is running are goldfields. As of April 10, there were still patches of goldfields blooming in the Lasky Mesa area.
