Green Lynx Spider Stalking Yellow Jackets

What killed this yellow jacket wasp?

Yellow jackets are a kind of wasp and many people fear them. Their black and yellow coloration is mistaken for honey bees and people are afraid of being stung. 


We have a low number of yellow jackets in the yard, but when you see them at a protein food source, like a hawk cast, it appears they are numerous. Video. When we first moved to this house 18 years ago, we couldn't eat on our patio without being harassed by 10-20 yellow jackets. We put out traps for them.


The problem was that we didn't have a balanced ecosystem. The previous owners sprayed for insects, baited for snails and planted mostly non-native plants. Gradually we have restored a more natural flora, which in turn attracts native animals–from insects to raccoons.


The Cooper's hawks are feeding their youngsters in the backyard. The young hawks are dropping bits of meat, this feeds the yellow jackets. But the yellow jackets are also eating the caterpillars that show up on my tomatoes. And the yellow jackets have a predator too.

Insects Feeding on Hawk Leftovers

The young Cooper's hawks are becoming the center of their own ecosystem. Their overworked parents bring food, drop it off and leave again, just that fast. With four juveniles that eat as much as they do, each parent is having to catch three times its normal prey. 


 
They aren't restricting their hunting to birds, they are bringing back whatever they can find. Rats have definitely been on the menu.


The juveniles eat their fill and then, similar to owl pellets, they cough up clumps of hard to digest bones and fur.


These "casts" are a bit gory, but they are in turn providing food to carnivorous insects like the yellow jackets in the video here. Listen and you will hear one of the young hawks calling in the background. Ants and flies are eating the leftovers, while western fence lizards are then pouncing on both species of insects. Spiders also will benefit. The ring-necked snake benefits from the success of the lizards.

Pre-School for Cooper's Hawks

young Cooper's hawk

The Cooper’s hawks have had a huge family this year. They first mated back in March. They must have lost the first clutch, but they are making up for it. There are four recently fledged juveniles hanging out in the backyard. In the morning and late afternoon they raucously call for their parents to bring them food.

Two of the larger juveniles are starting to follow the parents. It would be fascinating to see if they are watching their parents hunt.

Catching enough food to provision the four youngsters, who are now as large as their parents, is a Herculean task. The parents aren’t being picky about prey; rats have even become part of the fare.

With four youngsters to watch over, it's understandable that while the parents were off with the bigger chicks when they first left the nest, they missed that the little one didn't want to be left behind. The little hawk was not yet able to fly and ended up on a neighbor's front porch, just steps from the sidewalk. The flurry of humans wanted to "save" the little guy. But these hawks are devoted parents, like most birds, I convinced everyone to give the parents time to collect their youngster. I relocated the juvenile a short distance from its landing spot to an area that was away from the sidewalk, shaded yet visible to the parents. The parents did return and communicated to their little one what it needed to do, to get safely up into a tree.

He is flying a little, but still not well enough to follow the parents. The smallest of the juveniles he's pictured here. He's hungry enough that he has started trying to catch his own food. His movements are not skillful and his attempts seem to be in slow motion. He went toward a group of house finches, who stayed just out of his reach, then he turned to go after a fox squirrel. The squirrel couldn’t believe its eyes at first. It moved just out of the young hawks reach, then actually came back to taunt the young bird.

When he isn’t calling for his parents, the young hawk sits watching the small birds that one day will be its food staple. He’s learning how they fly, their alarm calls, how they respond to threats. His sharp eyes are ever watchful.  Cooper's hawk on fountain.

Meanwhile the California towhees are taking no chances. They are teaching their youngster to fly under the covered patio and carport. No use tempting the young Cooper’s hawk to make its first self-caught meal a young towhee just learning to fly.

Sometimes biodiversity surprises you by appearing in unexpected places. Walking through the garden from the garage, this juvenile or nymph katydid jumped onto a load of clean laundry and rode into the house.

Katydids are herbivorous insects and they do nibble on my roses at night. But they also are important food for many of the bird and lizards that eat insects in my yard. As long as predators can find clean, safe food in our yard, they come and maintain a balance. Only two or three katydids seem to survive to adulthood.

Two species of katydids, common in the Los Angeles area, are both residents in our yard.

This nymph is a fork-tailed bush katydid (Scudderia mexicana); it will grow up to be all green with long, thin leaf-shaped wings.

The other species we see is the broad-winged katydid (Microcentrum rhombifolium) To see a photo of this classic, katydid with wide, green leaf-shaped wings.


Insects that eat your plants are best kept in check by a balanced ecosystem with predators. Put the insecticides aside and attract insect predators to your yard.

Small Blue Flower in Garden

The small bracted dayflower (Commelina erecta) on the hillside creeps close to the ground and is inconspicuous to humans. But it’s fleshy leaves are enjoyed by the tortoises that live with us. The tiny flowers bloom for 1-4 days attracting the native carpenter bees and pollinating flies.

It grows in disturbed soil and is a highlight of our garden in dry shady areas. Finding a ground cover for dry shade is not easy. The intensity of the blue flowers is like the burst of flavor from a ripe blueberry.

California Spiders

On this longest day of the year, I'm looking for biodiversity.

American house spider

Rachel Carson wrote in Silent Spring that in a healthy environment there should be at least one spider within 3 feet of you at all times. Spiders are the Earth’s dominant predators. On any day I can surprise myself with the variety of spiders I can find.

Look for the fragile webbing strung under this dead flower.

A small American house spider (Achaearanea tepidariorum) has constructed a web beneath a spent bird-of-paradise (Strelitzia reginae) bloom.
While a trashweb spider (Cyclosa turbinata) may stay hidden, but it’s web is purposefully visible stretched between the branches of a dwarf lime tree. Several generations of this spider’s great grandmothers have called this tiny tree home. The collection of debris in the center is wrapped with silk that reflects ultraviolet light waves and is therefore believed to attract flying insects. This spider truly lures in its prey.

These spiders are important predators eating insects, providing spider web that is used by many birds in constructing nests, and the spiders are in turn eaten by larger animals.  If you have spiders you are on your way to healthy habitat.

Discovery in the Garden

For the past few weeks I’ve been crazy busy with work, tasks generated by the wants of people. It sucks you in until it seems important, urgent, even vital. But in reality the pushing of paper from one pile to another, the sprinkling of well-placed words and the measuring of spaces between lines of text is a never-ending job without surprise or discovery. In other words, most of us humans are engaged in lifeless pursuits.

This morning, I went out into the yard for just a few minutes and watched two different species, a valley carpenter bee and an Allen’s hummingbird drinking nectar from the same “lipstick sage.” The amazing thing was they each approached the plant in a different way. The hummingbird drank directly from the red trumpet flower. The bee grabbed onto mature flowers that had turned white and licked at the outside base of the bloom. When it did this, the flower trumpet dropped under its body and the bee was put in a position where its legs went into the flower thereby delivering pollen.

The variety of species that are living in this small suburban plot of land has increased dramatically since I first started documenting and replacing “traditional” landscaping with plants and features that would create habitat. (hummingbird territories)

Discovery is a daily occurrence in a natural habitat; and that natural habitat doesn’t have to be a distant rainforest. Everyday the habitat that surrounds my home offers me real moments of life–survival, birth, death, discovery and change.
