wildlife crossing

The Wallis Annenberg Wildlife Crossing—the largest of its kind in the world—is currently under construction nearby. I climbed the hill out back and saw it in the distance, spanning the 10-lane 101 freeway. Decades in the planning and fundraising, this vital structure will protect biodiversity across the region by linking undeveloped land that‘s currently fractured by major roads. It’s hoped that it will help prevent the extinction of our threatened mountain lion population. The crossing is due to be completed some time next year.

The lower parts of Solstice Creek are well-visited, but not many people climb Sostomo Trail to enjoy the gorgeous crossing on the upper creek. The three of us settled into a bed of fallen sycamore leaves and enjoyed the quiet shade. I liked seeing the little backswimmers (Notonectidae family) — I’d also observed these aquatic insects in Australia.

Backswimmers, as the name implies, swim inverted, using their long hind legs to paddle vigorously. They prey on organisms as large as tadpoles and small fish and can deliver a painful “bite” to humans—actually a stab from their sharp proboscis. These insects inhabit still freshwater in lakes, ponds, and marshes, and can also be found in garden ponds and occasionally in swimming pools. Despite being primarily aquatic, backswimmers are effective fliers, allowing them to easily disperse to new habitats.
