The day before the Angeles Crest 100, after checking in for the race in Wrightwood, I drove over to Inspiration Point to have lunch, go for a short hike, and enjoy being in the mountains. The day was exceptional.

While running in the Marin Headlands last weekend it occurred to me that it had been at least a couple of months since I’d done a a run in Pt. Mugu State Park. In addition to following the recovery of the area since the May 2013 Springs Fire, I’ve been surveying the effects of the December 2014 flash floods in Sycamore Canyon and its tributaries and hadn’t yet looked to see what happened in Serrano Canyon.
When doing a run in Pt. Mugu State Park I almost always start at the Wendy Drive trailhead. I’ve run from that trailhead to Serrano Valley and Canyon a couple of ways. Both routes connect by way of Satwiwa and Danielson Road to the Old Boney Trail. One follows the Old Boney Trail all the way to the Serrano Valley/Canyon Trail. The other climbs up and over Boney Mountain, eventually connecting to the Backbone Trail, and then descends the Chamberlain Trail and rejoins the Old Boney Trail about a mile east of the Serrano Valley/Canyon Trail.
Today’s run was a variation of option B. After climbing Boney Mountain to Tri Peaks, I ran over to Sandstone Peak using the Tri Peaks and Backbone Trails. Sycamore Canyon Fire Road, Two Foxes Trail and Upper Sycamore Trail were used to get back to Satwiwa and the Wendy Drive trailhead from Serrano Canyon.

Poppies along the Two Foxes Trail in Pt. Mugu State Park. From Sunday’s run to Mugu Peak and back from the Wendy Drive trailhead in Newbury Park.
I was on the way back from Mugu Peak and about four hours into my run. I’d stopped at an exposure of Miocene age shale along the Upper Sycamore Trail. The gray-brown rubble is home to an intensely blue-purple wildflower called spreading larkspur (Delphinium patens ssp. hepaticoideum).
I’d just snapped a series of bracketed exposures of one patch of the flowers when suddenly there was the bumblebee-on-steroids buzzing of a hummingbird in front of me.
At least I thought it was a hummingbird. It sounded like a hummingbird and was about the right size. Its blurred wings were shaped like a hummingbird’s. It flew with the precision of a hummingbird, darting from flower to flower, deftly feeding on each blossom’s nectar using its oddly shaped beak.
But it wasn’t a hummingbird — it was a hummingbird moth — a white-lined sphinx (Hyles lineata). I’d read about hummingbird moths, but to have one suddenly appear and start feeding on a larkspur plant I happened to be photographing was extraordinary.
Apparently the problem of feeding on the high-energy nectar in certain types of flowers is sufficiently definitive as to have produced a very similar evolutionary solution in wildly different organisms.
The sphinx moth is described as flying like a hummingbird, but which lineage produced this elegant solution first? It may have been the moth! A trace fossil of a sphinx moth found in Early Eocene Asencio Formation of Uruguay appears to predate the earliest known Oligocene fossils of hummingbird-like birds! In any case it appears that both hovering moths and birds co-evolved with the flowering plants on which they feed and pollinate.

Following last year’s drought-induced hiatus goldfields are once again blooming in profusion on Lasky Mesa. The little yellow “belly flowers” tend to grow in low spots and along paths where rain water pools.
